Mistakenly remove reference of the whole project in Xcode - xcode

I am working on an iOS project but mistakenly I just remove reference of the whole project in Xcode. After that, I have tried to add all of these folders and files but now the scheme is gone that's why I can't build the project anymore. Can we fix this horrible problem?

This is an ugly work-around, but it has been known to work.
Start a new project with the same name (just stored in a different place)
Remove all the code from the project navigator, including the storyboard
Import all the files and the storyboard from the original project.
Double-check the storyboard (I had problems with loss of segue IDs)
It took time, but at least it made the codesign problem go away.

Issue with Xcode in Main.Storyboard

I've been working on a project the last few weeks in Xcode and everything's been great. Main.Storyboard all of a sudden, will not load or open. Other projects open fine. There hasn't been any significant changes in this project. The last thing I tried doing was adding a navigation bar to one of my view controllers, to add buttons or items. I also tried adding a navigation item. Things started to complicate after trying to do these things. I have the latest version of Xcode, my project settings are linked correctly and tried rebooting my Mac but it doesn't solve anything. Does anybody know what may have caused this error and how to resolve?
The easy way:
Check out the latest working version of the storyboard file and try the changes again. Likely something odd and transient happened that corrupted the existing storyboard file (I've seen it happen with managed object model files before which are also XML underneath).
If there are too many changes to redo them:
Make a copy of the current storyboard file outside the repo and then checkout the latest working version of the file from the repo.
Diff the two files moving over changes that make sense from the troublesome file keeping an eye out for balanced tags (i.e. if a view has an opening tag but no closing tag Xcode will get confused).
Try opening the modified storyboard in Xcode. With luck it will open and be fine. Otherwise you will need to do a bit more digging or go back to option one and redo the changes.
I downloaded your repo and I can open Main.storyboard just fine:

Xcode 8.2.1 becomes unresponsive when i click on main.Storyboard

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.

After updating Xamarin and Xcode, failing to run app on iOS device

I recently updated Xcode and Xamarin and when I deploy my project to my simulator on iOS it works well. But when I however try to use my phone that has been working succesfully for many months now it does not work and I get this error in the log:
System.IO.FileNotFoundException: /Users/Carlos/Projects/Myproject/iOS/obj/iPhone/Debug/build-iphone8.1-9.3.2/ibtool-link/LaunchScreen.storyboardc/02J-Ip-oVM-view-Ze4-5b-2t2.nib does not exist
My bundle identifier matches my provisioning profile that I have made on apple.
I have tried to delete the obj and bin folders in the projectmap/mainmap (not the obj and bin-folders inside the iOS folder) but without any success. I have also rebuild the project and cleaned it but the problem still remains.
When I create a brand new project however it works. So it seems to be a problem with old projects only.
In the map on my old project I cannot even find "ibtool-link" and if I check the newly made project I just made i can see it there and other maps as well. Can I solve it by copying them over? Or is there a better solution?
Any ideas what it might be?
You might try the suggestions (I saw at least 2 different ones) in this post which are:
simply right click on the xib and open it in IB. I then turn around and close it in IB and that gets me past the error.
And
make sure 'Main Interface' empty in info.plist.
Remove Bin and Obj folder.
Also you might try deleting the build cache on your mac by going to /Users/<Your User Account Name>/Library/Caches/Xamarin/mtbs/ and then delete the folder that is the same name as your solution (there might be 2, one with iOS in the name, delete both). This will get recreated when you rebuild your solution.

Problems adding Projects to Workspace in Xcode 4

I have a couple of projects that I had started under Xcode 3.2.x some time ago. I switched to Xcode 4 a few days ago and want to make use of the Workspace feature as both projects. Basically, my plan is to extract some common features out of the two projects and make them a common library that both projects depend on. However, before I even get to the tricky bit of dependencies I get stuck just adding my two projects to the workspace.
I tried creating a new workspace and selecting "Adding files to " from the context menu; I then select the .xcodeproj file from my first project and it appears in the left-hand side tree browser in my workspace. However, it's just the file, not the project that I get. That is, rather than getting a two-line entry in the tree browser where the first line states the project name and the second line says something like "1 target, iOS SDK 4.3" like in the Apple documentation, I get a single line simply stating the name of the .xcodeproj file including the extension. There is also no triangle on the left to expand the node. It's like I just dragged some file in the workspace, not a project. The same goes for the second project.
I have also created a new Project "Foo" from scratch in Xcode 4 and added it to my workspace, with the same result. I looked at Apple documentation and watched the 16 second video about a dozen times now, but cannot work out what I am doing wrong (if the problem is indeed in the chair and not in the computer).
I had this exact same problem. I think it stems from having another workspace already open referencing the project you want to add. I got it working by:
shutdown xcode completely
double-click the workspace to launch Xcode and open just that workspace
drag and drop the project file from the Finder
Worked fine. I have many workspaces all referencing an openssl project, and it seems to work OK when you only have one workspace open at a time in Xcode.
Actually, I made it work without exiting Xcode.
All you have to do is make sure the projects you want to add are closed, since Xcode is having trouble adding open projects to a workspace.
So:
Close the projects you want to add
In the Workspace window, choose "Add Files to MyWorkspace"
Add the .xcodeproj file of the project you want to add
I had the same problem. SO I just exit xcode, restart it. Then I can see the files under the project.
Exiting Xcode completely and then double-clicking the .xcodeproj file to open the project.
It works but when you add an activity to the project than r.java file is automatically removed and errors are coming.

Xcode 4 code sense is not working

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.
