Fixing file 'project.pch' has been modified since the precompiled header was built error in Xcode

I was recently working on my application messing around in the info.plist section, and since that my application will not run on my test device:

file 'project.pch' has been modified since the precompiled header was built

Something to note is that the app runs fine in the simulator.

Edit: Now I am getting this error instead of the other one:

No such file or directory (/Users/Me/Library/Developer/Xcode/DerivedData/MyProject-abcdefghijklmnopqrstuvwxyz/Build/Products/Debug-iphoneos/MyApp./MyApp)

How to regenerate the info.plist file?

You could try a deep clean (not the same as Product > Clean) - Option+Command+Shift+K

Note: this means the clean the build folder (by pressing Option + Product -> clean folder)

1. Close your project or workspace.
2. In Finder: ⇧shift+⌘cmd+G
3. Paste: ~/Library/Developer/Xcode/DerivedData/
4. Delete the ModuleCache folder and empty trash.
5. Open up your project.
6. Clean: ⇧shift+⌘cmd+K
7. Build: ⌘cmd+B

In my case the error message had a small hint:

note: after modifying system headers, please delete the module cache at '~/Library/Developer/Xcode/DerivedData/ModuleCache/5CYAJ91AZCB7'

I tried and it worked.
