Suddenly I've started to get this error LaunchServiceError
If I rename the main folder say from ProjectA to ProjectB
then the LaunchServiceError goes away, as soon as I name it back to the original folder name, the error returns.
Any ideas please?
Based on the error my guess is that you're not opening Xcode Instruments in the recommended ways:
https://developer.apple.com/library/ios/documentation/DeveloperTools/Conceptual/InstrumentsUserGuide/LaunchingInstruments.html
Basically always make sure you launch it through Xcode (or an Xcode application menu by right clicking on the Xcode icon, etc). As well, make sure to always save your .trace file using Save As in Instruments, so that you can ensure it's saved with a unique name.

Whenever I close Xcode and then open it again, some file gets deleted and I have to start all over again. When I checked the file status it says locally deleted. Is there a way I can fix this :
Thanks
There is a possibility that your 'red' files (classes) are not at the same location as they were the last time you opened the project.
Find the files which were red, add them back to your project, and
delete the red links. Assuming, that you haven't deleted them by
mistake. (in case you did accidently - here's a hack)
Check the full path of the missing file or 'Show in Finder'. Can you access it?
If this doesn't help, I found this useful thread when I was using Xcode 4.1 earlier. Check it.
There were around 200 files I had to delete in my Xcode project (and yeah, they were deleted properly), and now I have to copy 200+ files are supposedly replace the ones I just deleted.
I keep getting "Multiple errors occurred while copying files". The Xcode window doesn't show the newly-added files, but if I explore the project folder using the Finder, I can see that the files were indeed added - well, there most likely was a certain file that could not be copied and thus caused the error. Problem is, I have no idea which one nor why.
Now then, is it possible to get Xcode to tell me what the problem is rather than telling me there is one?
Edit: Okay, I did discover that some of the new files shared the same name as some files that were not listed in Xcode, which explains the error. However, I am still interested in knowing whether there is a way to know that the "Multiple errors" actually are whenever Xcode says t his.
When Xcode finds a duplicate file, it generates this error, and then it fails to add references for the files that it did manage to copy.
Rather than deleting files from the finder and starting over, you can do this:
Open the Finder for your project, where your source files are located
Command-click the ones for which your references are missing (and if you click others, it won't really matter)
Drag them into Xcode. When the confirmation dialog comes up, unset the "Copy items into destination group's folder (if needed)" checkbox. This will tell Xcode to make references only.
I deleted the files from finder and then added again the files via Xcode, that worked for me.
This error sometimes occurs when the code is not merged properly. The missing files will not be available in Xcode but once you open the finder containing this project, you will be able to spot the missing file.
The simplest way to add these missing files back to the project is:
1) In your Xcode, navigate to Build Phases Tab.
2) Under Compile Sources, tap on '+' to add back the missing file.
Sometimes the missing files will be greyed out in the build phases, just tap on '-' and add them back.
For me this is worked. I tried to add files which are already in my bundle. So make sure you are not adding files which are already added. I hope it helps someone.
I've been having this problem for a couple weeks now. All of a sudden this happened to my project and I havent been able to fix it. Its a basic tab-bar app and i've barely even started heavy coding on it. Running xcode 4.6.2 (tried on 4.6 and 4.6.1 also).
The actual error says:
"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."
Thanks in advance.
Well here's my new fix: I had (for some reason) changed the highlighted line below:
I had changed the ${EXECUTABLE_NAME} to something else. Changing it back did not fix the issue immediately: I had to first click the + to add a new row then delete the new row.
My app runs fine now
OLD FIX:
OK, so yes, it's true, there are other questions like this one. They helped me figure out a different (and stranger) solution.
I right-clicked on my .xcodeproj file and chose "Show Package Contents"
I then opened "project.pbxproj"
I copied all the text from it to another file, deleted all the text from it and saved
This "crashed" my XCode Project that I had accidentally left open in XCode.
I closed my project, then pasted the original contents of "project.pbxproj" back into "project.pbxproj"
I saved "project.pbxproj" and closed it
After opening my XCode Project again, I was able to run it on my device!
To me, it doesn't make sense why this worked because I didn't modify an files... But it did, so hurrah!
PS
Back up your project beforehand, just in case.
EDIT: Well mine has stopped working again and I can't use the above method to fix it...
Using Xcode 4.5.2
I occasionally want to rename a project all the way through the project without leaving obvious folder name atavisms from previous versions in the project 's file system.
The usual instructions for renaming an Xcode project do not accomplish this. I have read them and done them many times. They only go so far. They leave the main directory (at the same level as the .xcode.proj file) with the ORIGINAL project name. Call me persnickety but I don't like that. So I endeavor to change it as follows.
I begin with the usual instructions, then attempt to rename the remaining original folder name both in Xcode and in Finder. It ends badly. Here are the steps I follow. It should be reproducible.
We will attempt to change a project named "JoeSchmoe" to "JoeSchmoe_1".
Do the Usual Project Rename Procedure
Create a new Xcode Utility project, named: "JoeSchmoe". Use Storyboards and ARC.
Build, run, and test functionality to verify that everything is OK. It is. Stop.
Hit cmd-shift-J
Open the Utilities panel on the right
Under Identity, change project name to "JoeSchmoe_1". Xcode will ask you, "Rename content project items?" Click "Rename"
Build. It should succeed. And it does.
The Problem
In the Project Navigator, notice that the main folder in the project is still named "JoeSchmoe"!
Change the name of that folder to JoeSchmoe_1
Build. It should succeed. And it does. We're done, right? Well let's look at the project's file system.
Quit Xcode
In Finder, open the folder containing the newly renamed and working "JoeSchmoe_1.xcode.proj"
(Its containing folder is still named "JoeSchmoe". That's ok for now. We could change it to anything without affecting Xcode, so long as it contains the .xcode.proj file and associated files and directories. We leave it alone.)
In that directory (at the same level as the JoeSchmoe_1.xcode.proj file), notice that the main project folder is also still named "JoeSchmoe" !!
Change the name of this "JoeSchmoe" folder to "JoeSchmoe_1". (We expect this to break the project because we know Xcode will still be looking for the "JoeSchmoe" folder, since it didn't change it for us.)
Start Xcode
Build. It fails, as expected.
Notice that all the filenames in the Project Navigator are now red colored, meaning files not found. (We expected this. Now we want to fix it.)
In the Project Navigator, select the project (top icon), then Target -> Build Settings -> Packaging -> Info.plist File.
Notice the file pathname in the Info.plist File settings row is named: JoeSchmoe/JoeSchmoe_1-Info.plist !! The directory still has the old project name. But in the file system we just changed it. So let's make this the same as what's in the filesystem.
Change its name to JoeSchmoe_1/JoeSchmoe_1-Info.plist
Re-Verify that the directoryname/filenames are identical in the file system and what you have in your Xcode Packaging -> Info.plist setting.
If they are, the project should build. Right?
It Fails. And all of the project files are in red (meaning not found).
Try cleaning the project (Product menu -> Clean),
Quit Xcode, Restart and Build.
It Fails, as before.
At this point I don't have a theory as to why it fails, other than to assume that there is an Xcode setting that needs to be changed somewhere that I haven't yet discovered. Looked all around for it. I'm stumped.
What am I missing?
Since they got rid of the feature that was in Xcode 3 to easily change your project name, it's been a pain in the butt to do manually. I found a great app in the mac strore Project Duplicator for Xcode 4 that copies your project and lets you name it whatever you want. I've been using it for a while now and have never had an issue with it, and it was only $1 when I purchased it.
GW
The last thing I had to change when renaming a project, including the finder folders, is the setting under "Build Settings->Prefix Header". It was still pointing to a finder folder that no longer existed and the compiler would throw on a file not found error.
Once I changed this to my new inner project folder, it all worked fine and I've been able to build the project as expected.
See this answer for fixing the problem manually
Renaming xcode 4 project and the actual folder
Coming from a background of Visual Studio I had no idea how good that IDE truly was until I had to work with Xcode. One of the more pressing oddities that it has just thrown up is the following.
I'm upgrading a project to a retina display and so have to add a bunch of new #X2 files. This is fine, I have the files and I go into Xcode, choose the project group where I want to add them, select them all and click 'Add'.
"Multiple errors occured" Xcode helpfully blurts and then returns to whatever it was doing before. No break down of what those errors might be, or what actually happened or why.
So I do some looking and some of the files are actually in the directory but Xcode ignores them, I can't figure out a way of adding them (it says they're already there!) but they won't appear in the xcode project.
Can I 'refresh' xcode so it looks in the directory and shows them?
==============================
PS. While I'm here and can rant a little, anyone with a VS background now using Xcode, am I wrong in thinking the following points are hugely annoying:
1) The debugger - frustratingly slow.
2) The file explorer - can't easily sort by name
3) The file explorer - column on the right listing the file names doesn't change the file highlight when you move from file to file within the editor window.
4) Adding files to a project - see above!
Some of these probably stem from lack of experience with the IDE but still, they irk.
Files in the XCode directories don't necessarily have to be in the project.
For some reason, XCode doesn't like overwriting files, and that's the warning message that I usually get when this happens too - "Multiple errors occured."
What I suggest you do is remove all of the #2x files from your project directory, and add them back into XCode using "Add Files..." Make sure you select "Copy files into project directory if necessary" though, otherwise they will just be referenced to their current location on disk.
