Obscure Xcode build error: “The file “myapp-SBPartialInfo.plist” couldn’t be opened because there is no such file.”

Question

I\'m getting the following error toward the end of the build:

error: could not read data from \'/Users/myname/Library/Developer/Xcode/DerivedData/myapp-ftieubjjfkuwy

Answer 1

In my case the problem was that somehow the Run action in my scheme showed my app's name without the ".app" extension. Editing the scheme and picking AppName.app fixed it.
