I am running a "old" Xcode 3 project in Xcode 4 and code sense is not working for my own classes. I have tried following:
Clean/rebuild
Remove Derived Data
Installing 4.3 documentation
Restart
Without any luck.
Sometimes the code sense works but mostly I just get "No Completions".
Try this:
Open Organizer then Project Tab.
Clear the "Derived Data". Xcode should re-index your project then and code sense should work. At least worked for me.
I know this is late, but for reference: http://sealedabstract.com/code/when-xcode-4s-code-completion-autocomplete-breaks/
Close the project, leaving XCode still running.
Open XCode’s Organizer window, go to the Projects Tab, select the correct project, and hit the Delete button next to “Derived Data”.
Quit XCode.
Navigate to your project’s .xcodeproject file in Finder. Right-click, choose “Show Package Contents.”
Leave the project.pbxproj file, but delete the project.xcworkspace file, any .pbxuser files, and the entire userdata folder.
Open the project in XCode. You will see XCode riding high on the CPU usage for around 10-60 seconds, depending on the size of your project. The activity window will say “Indexing”
When your CPU spike returns to earth, code completion will be working again.
There's a lot of deleting going on there so please be careful, but this definitely worked for me.
I've been doing this, and it's worked multiple times for me (after trying all of the above previously).
Edit: Now I just hit space, backspace (the mac version) and rebuild... works nice. Then, remember to scroll (sometimes the colors don't show up until you scroll somewhere)
Find your prefix file: "ProjectName_prefix.pch".
Comment out some line. (basically change it)
Build your project, doesn't matter if it fails or not.
Uncomment it.
Build again.
I'm betting only step 2 (modify the prefix) is what does it, but these essentially get you back to running. Suddenly everything magically recolors itself and completes functions.
Good luck if that doesn't fix it, perhaps try doing this to your dependency pch files (three20 or FB api's)
Clearing the "Derived Data" only works temporarily for me. I have to do it and then restart Xcode like 3-4 times each day to get code sense working again.
I found out the real cause is in the Target's Build Settings. I moved everything from Header Search Paths to User Header Search Paths and it is fixed. In my case, the framework I'm working with is RestKit.
BTW, I came up with this because I was adding another project (QuickDialog) into my project and I was curious that it is using User Header Search Paths, but not Header Search Paths. Here is the difference between them.
You can able to fix that issue by change build settings like this, PreCompile Prefix Headers :NO
FYI, if one file doesn't have code sense but the rest of your project does, check that its added to a target. Once I did that I got code sense back in that file.
It's been ages but the answer is just to move the code into a new folder and the code sense should be working now.
This happened when I added a new Objective-C Class and the code sense doesn't work only on the newly added .m and .h files (on XCode 4 latest update during this post).
Close all xcode windows
Delete all your projects from xcode>window>organizer and restart your project. It will now sense and index your project properly.
I wrote about it in detail here.
Basically my fix was that with localization. I upgraded from xcode 3.2.5 to xcode 4 and then screwed around with built in interface builder and turned on localization for a XIB file accidently which placed my source files in en.lproj directory. After moving them back to Classes folder it worked perfectly.
Again, for the sake of helping others with this issue which, in my case, happened upon upgrading to Xcode 4.3.
Of course I tried the solutions offered in this post, and none of them worked. But the suggestion to move the location of the project in Finder brought back some Code Sense, but the suggestions didn't make any sense.
I ended up deleting my project and re-cloned it from the git repository.That brougt back Code Sense for me...
I open a second project in the background whenever my Xcode's code sensing stops working (it usually works the first time i open the project but after a while code sense no longer works). So what i do is to open a second project in Xcode. Xcode will start indexing the second project and magically the code sense for my main project is back.
Running Xcode 4.3.1 on Lion
Hope this helps someone.
From this comment here I was able to debug the problem on my end, it seemed to be a bad -w flag that the clang preprocessor wasn't recognizing properly. Basically, running
defaults write com.apple.dt.Xcode IDEIndexingClangInvocationLogLevel 3
in Terminal increases the verbosity of the indexer, and should help you track down issues. Open Console.app and look for messages from Xcode, the search string IDEIndexingClangInvocation helped me find them.
For me it happened simply because the file had no target membership. If the first few answers did not work for you, go to your .m file (presumably it's this file that you're having trouble with), open the Utilities view (Edit -> Utilities -> Show File Inspector) and under "Target Membership" check the target to which you want this file to belong.

This morning, Xcode 9.0 (9A235) shows a new/strange Auto Complete box that is not at all what it used to be. How do I get the full auto-complete box so that autocomplete looks like how it usually does?
Try:
Go to Xcode > Preferences > Text Editing
Under Code completion - Uncheck 'Suggest completions while typing'
Quit out of Xcode and then relaunch Xcode.
Go to Xcode > Preferences > Text Editing again
Quit out of Xcode and then relaunch Xcode.
Now go to Code completion and check 'Suggest completions while typing'.
Try typing library function or enum and enjoy!
Deleting the DERIVED DATA folder seemed to fix my issue. Thanks to this post: swift println() not showing autocomplete options while writting code
Things to try:
#1
Run this command in the project directory if you use cocoapods:
rm -rf ~/Library/Caches/CocoaPods;
rm -rf Pods; rm -rf ~/Library/Developer/Xcode/DerivedData/*;
pod deintegrate; pod setup; pod install;
#2
**Clean Cached Data**
Clean the Project -> Cmd+Shift+K
Clean the Build Folder -> Cmd+Shift+Option+K
If you skipped step one:
Delete Derived Data
Xcode Preferences -> Locations ->
Arrow Symbol Takes you to DerrivedData -> Delete Folder
#3
**Check your Build Phase's Compile Sources.**
Every .swift and .m file in the project should be in this list or it won't autocomplete in those files.
#4
**Optimize your Editor:**
Use fileprivate* on every class property and function that you can to reduce the scope of the Compilers work per item.
Write modular/OOP code so you have less code for the compiler to read.
Avoid using Type Inferance when the result is a complex calculation, and try to break down complex calculations into let this = smallerOperation statements
* In Swift 4 private became stricter than fileprivate
In Xcode 12 there have been significant improvements in how often deleting derived data is necessary (though freezing has increased).
Xcode Version 11.0 (11A420a)
I have tried the solution from Lal Krishna for Xcode V11.0. It worked a few times but later I got no result.
I found one solution. You must delete two files:
Library/Developer/Xcode/Derived Data (as described before)
Library/Developer/Xcode/UserData/IDEEditorInteractivityHistory
That solution helps me now. May be useful for others 😉
This can happen when the file is not a member of the Target. Open the file where autocomplete is not working and show the the "Utilities" tab in the top right of Xcode (blue in the screenshot below).
Ensure your Target (typically your app's name) is checked. Autocomplete should work almost instantly without restarting Xcode, cleaning, or deleting Derived Data.
If it is already checked, make sure to uncheck and recheck it again. For me, it did the trick.
I'm using Xcode 10.2 and I had the same issue.
This answer from axel helped me to fix.
Anyway, I'm going to describe a bit more:
Go to YourProject.xcodeproj by clicking with Right Mouse Click and open Show Package Contents
Go to xcuserdata and delete your youruser.xcuserdatad
If you have also the xcworkspace(if you already have any pods installed) then do step 3&4, if not then just skip step 3&4:
Go to YourProject.xcworkspace by clicking with Right Mouse Click and open Show Package Contents
Go to xcuserdata and delete your youruser.xcuserdatad
Quit Xcode
Delete Derived Data by using Terminal:
rm -rf ~/Library/Developer/Xcode/DerivedData
Open Xcode and check if it works.
This can also happen if you redundantly named your files. For example,
Data.swift
Data.swift
Here's a bit of workaround but works.
Clean the project... Command + Shift + K
Clean the build folder... Command + Shift + Options(Alt) + K
Delete derived data for the project...
This can be done with the help of this link:
How can I delete derived data in Xcode 9?
Close XCode.
Reopen XCode (let the indexing complete) and Build the project... Command + B
Once it will be done with building, The suggestions will be back. I have tried it twice.
Update:
Sometimes the issue can be as simple as Duplicate file names.
Carefully check if any new file names added by you are conflicting with older files.
In Xcode 11.4, even if you move an existing file to another group, the suggestions disappear. This can be cured simply by restarting Xcode.
Removing the file from the Test Targets fixed my problem.
After a long time of searching, I finally fixed the issue for me. In Xcode > Preferences > Text Editing, in "Code Completion", I had "Use Escape key to show completion suggestions" checked for some reason. As soon as I unchecked this box, auto completion worked like a charm, without even needing to restart Xcode! (Xcode 10)
Please try doing this:
Select the file >> check if the file is added to UITesting or UnitTesting targets (File inspector -> Target Membership). If so, please uncheck those two and make sure only the project target is selected. Then build and try if autocomplete is working fine.
This worked for me. Hope it help someone.
For Xcode 11.4 (11E146)
Back Slash in folder name breaking the autocompletion feature, If this is the case remove it and build again.
I added here what was going on in my project just in case it can help someone else... I had 2 files with the same name and I didn't realise.
Just lost a day trying to solve the autocomplete nightmare of Xcode (9.2). Deleting derived data seemed to work briefly then things reverted. Reboots etc and other suggested voodoo failed to make a difference.
I gave up and download the 30 day trial of AppCode from Jet Brains. Autocomplete worked fine there and this maybe coincidence but it then started working again in my project in Xcode. Can't guarantee that it'll keep working...
It seems to be file specific in my case (Xcode 9.2) For me the fix was:
Delete problem file (remove reference)
Clean and Build
Add file back into the project (I did not check test targets)
Build again
Finally after 3 hours of trying everything - autocomplete works as it should.
Problems mostly because there are missing location of some files in project navigator (build errors)
Press command+1 to open Project Navigator pane
Check if there are any missing files
Or you can:
Delete DerivedData (command+shift+K)
Clean build folder (command+shift+option+K)
Press build again (command+B)
You should see build error that Xcode could not find some files that prevent build tool to process auto complete.
Correct and fix any missing files that you see.
Hope this helps
Use Command + B
or Command + R to Build or Run the project
Xcode sometimes messes up ;)
Xcode 11.3, macOS catalina
process parsecd achieve 100% of cpu, so kill it helps me
goto underneath directory and delete all folders on it.
{Your User}/Library/Developer/Xcode/DeriveData
It worked for me.
For me it was happening in my test file, because it wasn't part of a target for some reason. Setting it's target membership solved the issue.
For me, the problem occured when I discarded all the changes of one file (under Source Control > Commit), which effectively deleted the file. This is what I wanted and I thought that the file and all references to it would be delted too.
However, there was still a reference to the file (shown in red) in the Project navigator. Deleting the (now non-existant) file in the Project navigator magically brought auto-completion back.
No amount of cleaning, deleting derived data, etc helped. I only realized the deleted file was still showing when I tried to build my project, which of course failed because it couldnt find that file.
Hope this will help someone save 30 minutes :)
check whether you selected the Suggest completions while typing in Xcode -> Preferences -> Text Editing
navigate to user->Library->Developer->Xcode->DerivedData in Finder and delete the DerivedData folder
My case might appear too specific to help, but it might give someone an idea of how to solve broken auto-completion. Xcode 10.2.1.
In my case, auto-complete stopped working entirely and non of these other answers helped me. In addition, the fan on the computer could be heard to go louder indicating something was overworking (no other apps running), it should be noted I was editing on a MacBook Pro laptop. It seemed to be linked with the editor struggling to parse the equation I'd written:
switch mtype {
case .indeterminate:
newPosition.x = (frame.width - mainFigureText.frame.width) / 2
case .right:
newPosition.x = (((frame.width / 2) - mainFigureText.frame.width) / 2) + (frame.width / 2)
case .left:
newPosition.x = (((frame.width / 2) - mainFigureText.frame.width) / 2)
}
I was looking to animate a text view left, right, or to the middle depending on user prefs. The newPosition is a CGPoint that the text will animate to. Anyway, I split the equations up and all of a sudden auto-complete started working and the fan went quiet! I've been able to recreate this specific problem more than once by re-typing the above code and then replacing it with:
let halfFrameWidth: CGFloat = frame.width / 2
let middleLeft = (halfFrameWidth - mainFigureText.frame.width) / 2
switch doseType {
case .right:
newPosition.x = middleLeft + halfFrameWidth
case .left:
newPosition.x = middleLeft
default:
newPosition.x = (frame.width - mainFigureText.frame.width) / 2
}
I would like to add one more to the pile of solutions, because it is the only one that worked for me and is nowhere to be found here.
Xcode normally comes with two default build configuration for every project. Release & Debug. I have an extra one for my unit tests called Testing. In Xcode 10.1, 10.2, 10.3 and 11 beta, the new build system does not seem to like it and will only auto-complete if you either use Release or Debug. Any custom build configuration breaks auto-completion in mixed (swift + objc) project with unit tests.
I faced the same problem in Xcode 11.3.1. In my case The issue was cause due to duplicate file names / Deleted file name. Better to run the application once and check whether there are any deleted files/classes so that you will get a syntax error.
This Link helped me. Open the Build Settings & fill the framework search paths. See the below image.
Build errors can break the autocompletion feature in Xcode.
I had the issue with 100% not working auto-complete, none of written here helped. One thing I noticed – it was broken right after adding some entities into .xcdatamodel file, which have codegen class definition by default.
So I wasn't surprised when using old-style codegen none (and generating classes of course) fixed the issue immediately, even without restarting the xcode.
With Xcode 11.1, simply performing Clean Build Folder or deleting derived data was not enough to fix autocomplete.
Only after restarting my Mac, everything was back to normal
If you have issue with weird completion/auto-completion/intellisense (not showing default stuff like delegates and datasource protocols methods) just change your target (e.g. from simulator iPhone 8 to real device), build the project and switch back to your original target.
Similar with issues with Interface Builder (storyboards) not showing anything, but only "nothing selected" whenever you select any part of the view. Just switch to other Xib/Storyboard (or even create new), check if it works there and switch back.
These workarounds worked for me in both cases (had both issues in one day with one project on Xcode 10.2.1). From what I've seen all over internet forums it seems these are bugs never fixed since Xcode 6.x or so.
Cheers!
First, there's one old question with the same issue, but since the answers don't work for me, i'm posting this one:
I had problems to open an old project at all. So i deleted xcuserdata and the derived data, from the options tab, too. This one worked fine and i was able to open the project, but now when i click on the storyboard Xcode "hangs" and i have to force it to quit.
This happens only if i click on main.Storyboard, every other file in the project works fine when i click on it.
The last thing i tried was to run the project and in the last 5 minutes, it says Compiling 2 of 2 Storyboard files and that's all; no other result at the moment.
edit: cleaning the project doesn't work too.
edit2: It seems the problem is with my Xcode, not the project. I created a new project and Xcode freeze when i try to open the storyboard. Same with some other old projects.
Next step: reinstalling the Xcode.
Ok, like i comment previously, i tried a lot of things before consider to reinstall Xcode, but the most important were to run the project in other Mac and when i saw that there was no problem to show the storyboard i concluded that the issue were in Xcode.
I reinstalled it and it works fine.
Before everyone does that it's probably a good idea to see if your project run on other mac.
You can also delete xcuserdata, the derived data and the Xcode saved state.
Among the other things i tried:
I restored the version of main.storyboard i have on time machine, just before the crash. Didn't worked, but worth to try.
I also considered to replace the file with the same but from some old version. But the problem was, that i've made too many changes on the actual storyboard, so i needed to find a way to restore it.
Cannot run on the selected destination
The selected destination does not support the architecture for which the selected software is built. Switch to a destination that supports that architecture in order to run the selected software.
I am using the Facebook-iOS-SDK from GitHub: https://github.com/facebook/facebook-ios-sdk
tested latest commit (2a030e795aed343e7614e149a5ebdfa78b223a72) and sdk-version-3.0.8 tag, both having the same problem. Tested the Hackbook, Scrumptious, FriendPickerSample on both iDevices and iSimulator.
It was working before (on older version of XCode), so it could be the xcode upgrade, but my other projects work fine. I've tried multiple solutions on this site which works for others but not on mine, does anyone encounter this before with Facebook-SDK specifically? Thanks in advance!
EDIT: I have found the issue, if you install the FacebookSDK and you add the resources folder to get the facebook image buttons there is a Info.plist file. XCodes goes weird with this info.plist file. I have deleted it, made a clean and now it works perfect :)
OLD:
The same behavior here. On another projects it runs perfectly but in this one I have always the same problem. After some XCode restarts sometimes it runs ok, sometimes I "click" on run and then nothings happens, sometimes it runs...
The best option is to move the project to other path. Adding and removing the libsql3.0 from lib dependencies sometimes works too.
Sadly, it seems like this is a bug on XCode, it will build and run fine for once every couple of restarts and with the entire project directory moved to other path. This is very sad because apple always make good products for consumer but all their developer software are crappy compared to big M's
I ran into this problem. It seemed to start right after XCode hung and I had to force quit. This was a day before the 4.6 update. I hoped that that update might fix the problem. And I did get one successful build before I started getting that message (actually in 4.6 there are two different but similar messages that seem to alternate.
I solve the problem by letting XCode update the project settings. I first noticed this possibility when I made a duplicate copy of my project and open that, but it is clear that this option is also available in the original. Here is what I did
In the Issues Navigator just under my project "MyProject project" I had a message MyProject.xcode
Validate Project Settings
Update to recommended settings.
I click on that and I was presented with a dialog box with 4 checkboxes some explanatory text and the option to perform changes. I just let Xcode make those changes and everything has been fine since.
Remove info.plist from Facebook Resources folder. Changed the location of XCode project and Reset the iPhone simulator...now it is working :) Buggy XCode !!
My "Run" button under "Product" is greyed out and after trying a few things from various forums, can't figure out what's gone wrong.
I've tried removing the project.xcworkspace and xcuserdata files and letting xcode generate new ones, but no...
My co-worker uses AppCode from IntelliJ and when he pulls the code, it runs just fine. But if he opens the same files in his Xcode, his "Run" is also greyed out.
"Edit" your current "Scheme":
Make sure you have "Run" checked for that build target:
The scheme need to be fixed (I don't know why xcode changed it)
Here are the required steps:
, ,
Make sure you have the correct target selected.
(Upper-left in Xcode window, near the triangular Run button.)
My co-worker who uses AppCode had edited the configuration file, moved some frameworks around, etc... We noticed that there was a difference between XCode and AppCode in using relative vs. absolute paths in the project.pbxproj file.
Ultimately I just reverted the code to before his changes, so at this stage, I'm not entirely sure which difference in the config file actually caused Xcode to not be able to Run the project.
**EDIT
From the .git logs, it looks like AppCode was adding relative directories with 7 sets of "/../" and before there were only ever instances of 5 "/../" to get back to the root directory.
Rather frustrating that Xcode had no way of dealing with this from inside the IDE.
I've built a small app using storyboards and it ran great. Just before final testing I decided to try it out to see if it runs on iOS 4.3. I clicked on the gray 5.0 in the project settings and selected 4.3.
The app failed to build with the following error message:
Storyboards are unavailable on iOS 4.3 and prior
Both the iPhone and iPad storyboards tell me that.
The issue that when I switched back to iOS5 target, I still keep getting these errors from both storyboards, and the product won't build!
I checked: iOS Deployment target in projects settings is 5.0
Target app deployment target is 5.0
Build settings uses iOS 5.0 SDK
What else do I need to do to restore my project to a buildable state? Is this a brand new bug or am I forgetting something?
Update: I kept getting this error even after doing a clean.
I changed the debugger in Schemes to "LLDB" and did an additional clean, the project now builds and compiles
I also got this problem and finally I solved this by following procedure:
Open XXXXXX.storyboard
Open Identity and Type tab in your right view of Xcode.
Set the value of Development in Document Versioning to "Xcode 4.2" (my default value is "Default Version (Xcode 4.1)".
Change the value of Deployment from Project SDK Version (iOS 5.0) to iOS 5.0, then back to Project SDK Version (iOS 5.0)
Rebuild the project and the error should be resolved.
The solution that worked for me was just to delete the ~/Library/Developer/Xcode/DerivedData directory for my project.
I'm just going to add this one as another possible answer here, as the first solutions worked for me several times (as I mentioned in my previous comment) until today when I couldn't get my project to compile for love nor money with the same error.
With the debugger changed and Xcode set to 4.2 and restarting several times I could not compile. However I discovered another way to get around this issue.
Select the storyboard in the left column and 'Show in Finder' and drag the storyboard to the desktop. Xcode will now change its colour to red and be unable to compile.
Clean the project, drag the storyboard back from the desktop to the directory in finder.
Then, it builds and the error goes away again.
I don't know what triggered the error originally as I'm developing under iOS5 and building for 4.3, but it seems to come up from time to time and.
This seems to be a bug in the latest XCode that I've also run into too, did try the OP's solution of changing debugger and that had no effect.
It cropped up for me since I tried storyboard with 4.3 and then tried to change back.
My solution was to close XCode, open it again and clean. Then I compiled and it worked fine.
Hope this helps others.
While other solutions helped me, they didn't work 100% of the time. I don't know enough about XCode to know how reliable this solution is, but at least it worked for me so you can try it in your project.
In the left hand side of Xcode, open the project navigator. Click the top item, which is your project. In the panel immediately to the right, you'll see a choice to choose between your project and its targets. Click the project, and then in the panel to the right, under the "Info" tab, set "Command-line builds use" to Debug (in my two projects where I was having the error, both were set to Release).
A picture is probably easiest:
Another idea: Open another project with storyboards in Xcode and try to run that. If it succeeds, you can come back to the current project and it should build. I think this clearly indicates a bug in Xcode.
After trying all the answers in here (removing the Storyboard reference, quitting Xcode, cleaning, changing debugger, etc.), none worked (with Xcode 4.5).
The only way I got it to rebuild (and it was a total guess) was to open the Storyboard file in a text editor and delete the following line:
<deployment version="1280" identifier="iOS"/>
It should be near the top of the file, in the <dependencies> section. After that, the project was built successfully and Xcode even re-added that line to the file, but, it still builds...
Go figure...! Hopefully it can help someone!
At last, an elegant workaround that seems to do the trick for me! (I sure hope it works for everyone else. This one's stubborn.)
Once your settings are back safely in iOS 5-land, try Cmd-Option-Shift K (aka "Clean Build Folder..." from the menu - hold down Option to see it), then build.
the solution is simple,
right click your storyboard file, and show in finder
then select the folder where the file is (this would probably be in the en.lproj folder)
right click on the MainStoryboard.storyboard file causing the problem and open with text edit
find the line that reads or something like this:
<development version="4300" defaultVersion="4200" identifier="xcode"/>
and change it to something like this:
<development defaultVersion="4300" identifier="xcode"/>
save the file and build. Et voila...
Ok, I tried everything above and problem still occurred. So I just remove storyboards (as reference not move to trash). then build successfully; after that I added them again; Build, And finally worked.
I was having the same problem. I tried all the above answers and all combinations and nothing worked. Then later after doing some research, I analysed that the simple fact that the error that was throwing at me was straight forward.
Just go to the Build settings and instead of selecting the xcode project file, select the product file and change the Deployment target to 5.0 or 5.1. The error should go off.! I did this in Xcode 4.3 in Lion OSX. It worked fine for me!!
I also had this problem, and nothing helped. Even opening another project and trying to build failed.
What I did, and what for me, was going to project -> info and under "Deployment Target" change iOS Deployment Target to whatever, build and than change back to whatever it was and build again.
Here is yet another random, voodoo, flail that seemed to workaround the bug just now. (after other techniques here had not helped) I renamed the storyboard file (and the entry for it in the info.plist file). Haven't tried the "drag to/from desktop" ritual yet.
Tonight, I have lost like 45 minutes to this issue. grrrrr. Ok I feel better now.
After trying all the suggestions above, without success, I got my code to compile doing the following.
Edit -> Refactor -> Convert to Objective-C ARC
rm -rf $HOME/Library/Application Support/Developer/Shared/Xcode
rm -rf $HOME/Library/Preferences/com.apple.dt.Xcode.*
rm -rf $HOME/Library/Saved\ Application\ State/com.apple.dt.Xcode.savedState
rm -rf $HOME/Library/Developer/Xcode
seems to help with Xcode 4.3.2
Had similar issue. XCode would build and run other projects fine but couldn't get rid of the error on project I had changed, not even backups from server. Tried all the above solutions but nada. Here is what worked.
Uninstall XCode.
Delete user/library/developer/XCode folder.
Reinstall XCode (maybe you should start this before searching for the folder, download took me 20 minutes).
Start up, clean and build.
Worked for me. Saved me some time. Sometimes when the scalpel doesn't work it's time for the hatchet. Now I get to pick a new font to code in (this will clear your preferences)!
The only solution that has worked for me is to create another project without Storyboarding enabled, build it, then switch back to the storyboard project, clean and build.
Here is yet another random, voodoo, disconnect your iPhone if it is connected.
I simple changed deployment target to 4.0 and Development to 4.3 from MainStroyboard.
I clean the project; and restarted the mac, :) i know it sounds funny but restarting xcode didn't helped. maybe there is a cache in memory...
Then i built the project ; it was ok!
