Obscure Xcode build error: “The file “myapp-SBPart

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-ftieubjjfkuwyrhhleghfevbhxuu/Build/Intermediates/myapp.build/Debug-iphoneos/myapp.build/myapp-SBPartialInfo.plist': The file “myapp-SBPartialInfo.plist” couldn’t be opened because there is no such file.

The only thing I can think of is that it is a result of having aborted a build an hour or so ago.

I have cleaned, quit Xcode, rebooted my computer - none of the easy fixes are working. I've checked the other build directories (Debug-iphonesimulator and Release-iphoneos), and neither of those directories contain the file either. But both the simulator and the archive are building correctly.

Xcode bugs are the worst.

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.

Answer 2

In my case, I resolved this by setting the Deployment Target to iOS 9.0 from iOS 8.0, as I had a UIStackView, which is not supported before iOS 9.0

Answer 3

I heard back from Apple Support.

Something was wrong with one of the generated files. Here are the steps to fix it:

1) Quit Xcode.

2) Open Finder and select Go > Go to Folder...

3) Delete the DerivedData folder

4) Open Xcode.

5) Clean your project

6) Build
