So I have an xcode project that fails every time I run it on my computer. Works on other computers though. I get the following error:
dyld: Library not loaded: /System/Library/PrivateFrameworks/Swift/libswiftCoreFoundation.dylib
Now, when I look in /System/Library/PrivateFrameworks/Swift/ I can't find the libswiftCoreFoundation.dylib file. But other swift projects work just fine. I have no idea how to fix this. I've tried cleaning, restarting my computer, creating a copy of the project, updating Xcode, updating command line tools, everything I could think of.
The project was working just fine a few hours ago. Something went wrong by itself. No clue how to fix things.
After spending 6 straight hours debugging and trying to fix things, I found the solution. For some reason, my "Library Search Paths" was filled with the wrong directory. I never set it to that directory. But it was set.
Here is what I mean:
The highlighted field was filled with the following: macosx/System/Library/PrivateFrameworks/Swift
I just took that out. I hope this helps save some future traveler the pain and torture I went through

Im running Xcode 9.2. My storyboards are completely useless now. Ive
experienced what this article shows and have tried everything the
article suggested.
My issue occurred when I tried to add a single swift file to an existing
objective C project with about 320 files in it already. I removed the
.swift file entirely from the project, then did everything in the article
link above and still nothing fixed it including removing/reloading XCode
several times trying different things.
I filed a bug with apple but haven't received any replies in a week (of course). Apple seems to be slammed with tons of bugs lately they keep
creating.
Now I cannot work on this project's storyboards at all and Im dead in the
water. Really not happy with Apple lately!
Is there anything more that anyone has had success in fixing this issue?
Im completely dead in the water on this application now.
Fixed this by setting the command line tools version to the correct one. Mine was blank in Preferences / Locations
For my case, whenever I open a storyboard from a workspace, this happens. So I got rid of cocoapods and workspace, then just use carthage for thirdparty libraries. Storyboards opens faster and without this error.
Note that the storyboard I am testing is empty.
This turned out to be stupidity on my part. I had a script that was killing certain processes on my Mac over and over and it turns out that was my issue. When I removed it everything worked as normal again.
I've spent the past few months converting a project of mine with about 1500 source code files into Swift. It was incredibly tedious, but I finally did it. It runs well, builds well, but:
When I attempt to archive the project, Xcode fails with the following error:
ditto: can't get real path for source '/Users/USER/Library/Developer/Xcode/DerivedData/
APP-dtsbrzschafjiubelceuxtfwstqf/Build/Intermediates/ArchiveIntermediates/APPCore/
IntermediateBuildFilesPath/APPCore.build/Release/APPCore.build/Objects-normal/
x86_64/APPCore.swiftmodule''
Command /usr/bin/ditto failed with exit code 1
APP being the app and APPCore being the embedded framework.
What I've tried:
cleaning the project (which really has no effect when archiving, since archive always compiles from scratch)
using Xcode 7.2 beta (released a few days ago)
making as many declarations as possible non-public
disabling any Swift optimizations for the release build configuration
building the APPCore framework as release - which actually works (!) - and does (!) create the .swiftmodule file
The last part being the strangest here. This evidently points to the archive doing something slightly different, but I have no idea what.
My question is if anyone has any idea why is this happening and how to debug this. I've spent the last two days trying to figure this out, but no results...
I've googled this error as well, but unfortunately, the answers were fairly limited and suggesting to comment all lines of code and then start slowly uncommenting them until the project builds. Which is OK for a smaller project, but not for a 25KLOC project, mainly when you have absolutely no idea where to start...
I had the same issue and your question actually helped me to solve it (Xcode 8).
In debug mode just got the "ditto: can't get real path for source" without any further information. Switching to release mode showed me that the problem was that the framework wasn't allowed to have a bridging header file. I went to the build settings and removed the bridging header file (don't know why there was one) and it now compiles both in release and debug mode.
My Xcode project is really starting to irk me.
I wrote a program that involved multiple png images. At a random point, it said that frown.png had no such file or directory so I renamed every instance of it to frown2.png and i still got the same error still saying frown.png even though there was no instance of it.
I then took all of my code and images and created a new project. For a while it worked, but when i tried adding a second view (doubt that caused it), i started getting the same error again still with frown.png.
What should i do?
(P.S. i am very inexperienced in xcode so please keep answers clear and concise. Thanks)
I've just followed the steps on the cocos2d site to install the latest xcode 4 project templates, however every time I try and create a Chipmunk/Box2d project it fails to build, stating there are ~26 issues.
I've read up on this a little and found that Xcode 4 change the way templates are handled which is causing the issue, but I haven't found what I need to do to fix this.
Any help would be appreciated!

Hey, I had the same issue as you but after a lot of searching I found a solution.
For some reason if your project name has a space in it then Xcode 4 doesn't link the Box2D framework in properly, thus giving you the 26 errors.
I recreated my project with a name without spaces and it compiled perfectly.
I've been working on a project in Xcode 3.2.5 and today I tried migrating it up to Xcode 4.0. It compiles just fine; I can navigate to and execute the .app without a hitch (as expected). The only thing that is screwy is the fact that Xcode cannot launch the application, and displays the following error when it tries:
"Error starting executable. No executable file specified. Use the "file" or "exec-file" command" (image not available)
I've scoured the Project and Xcode settings and have been googling for half the day, but all I can find are dead ends and people bashing other people about breaking Apple NDA. FYI Xcode 4 has been released, and is no longer under NDA.
Should I just start a new project and copy in my source? Sounds wrong to me, but brute force works when brute force works.
Thanks in advance
At a guess, the schemes it set up for you based on your v3 targets and build settings might not be quite right. From the schemes menu, choose to edit the current scheme, then select the Run action from the list and make sure the appropriate exectuable is selected.
I ran into the same issue this question came up so I spent my time identifying the issue, reproducing the issue, narrowing it down and explaining as best I could how to not make it happen - as well as the general frustration that comes with an issue like this (it hit me on 2 different versions of Xcode in 2 weeks).
If you're going to delete my post then at least take the time to try and answer the question as I had tried to do.
Now, on to the reply that actually tells how this issue may be created and how to avoid that.
I JUST had this happen creating an app for iOS. Why? I renamed my target executable.
Just tested this by checking out a new copy of the source and rebuilding.
The app ran fine on my device.
Went in to Xcode 4.2, renamed the target. Ran the app. "Error starting Executable..."
I changed the filename back. Same error.
Cleaned and ran the app again and it launched.
Renamed the app, cleaned and ran it again. Not so much luck.
Don't rename your app by renaming the target.
This is such a stupid limitation. Apple lets you rename your target app, but by doing so, this prevents your app from launching on the device.
EDIT: I haven't checked in any code, but now I can't check out and build and run any app without this happening. How do you get the device/xCode out of this state once you've gotten it in to it?
Even the app now crashes on launch at int retVal = UIApplicationMain(argc, argv, nil, nil);
This is in Xcode 4.2 on Snow Leopard, but I got into the same state with Xcode 3 on another Machine last week.
Edit 2: Rebooted the device, rebooted my Mac. Built and ran in the simulator first, then on the Gen4 iPod touch. It works.
I had this issue when migrating a project from Xcode 4 to 4.1, and it ended up being due to the Target's "Product Name" being different in the debug and release configurations. A holdover from when I changed the name of the product many versions ago. So check that...
I've downgraded Xcode from 4.2 to 4.1 only to encounter an error at build and run on device: "Error starting executable. Don't know how to run ...". I've cleaned the project (Xcode > Project > Clean) and cleaned the build folder (Xcode > Project > (hold option key) Clean Build Folder). After that I had to build again and it built okay on iPod touch 4g running iOS 5.
Well, it sure sounds like a whole family of bugs behind that error message!
I got the error after loading up an Xcode 3 project under 4.2.x for the first time.
None of the above tips worked for me, however what I eventually did was switching from GDB to LLDB.
That fixed it.
It looked like the new path to the executable wasn't properly recognized by GDB (i.e. once locally at PROJECT/build/Debug/... in Xcode3 but now in the usual temp. folder location with Xcode 4 it was still looking for the executable in the build folder relative to the project sources)
I duplicated the target and rename the copied on to different name, I got this error message. What I did is to clean the project, exit Xcode, restart the Xcode, then it can run on my device.
