Xcode 10.2 Update issue Build system error -1: Unable to load contents of file list: input/output xcfilelist

Question

After upgrading to Xcode 10.2 I am getting 2 errors

:-1: Unable to load contents of file list: \'xxxxx/Pods/Target Support Files/Pods-xxxx/Pods-xxx

Answer 1

For me, this was caused because I was setting up a custom configuration (.xcconfig) file for different environments. I wasn't importing the Pods/Target Support Files/Pods-XXXXXX/Pods-XXXXXX.release.xcconfig into my configuration file.

This guide helped me find the missing step. https://thoughtbot.com/blog/let-s-setup-your-ios-environments

Thanks Patrick.
