Xcode 10.2 hangs during Archive on arbitrary Task

This question has been asked before with prior Xcode versions:

Their solutions were:

• Remove armv7 from Valid architectures
• Change debug information format to DWARF instead of DWARF with dSYM File

I have tried all of these but the archiving still gets stuck at a particular task, always the same task number.

I have looked into the report navigator, and their are issues. But just warnings. There is one error "FontAwesome" build target, which doesn't say much. But the app use to build with version 10.1

For those that come across this issue, it was because of FontAwesome. I had installed it via CocoaPods. Not sure what the issue was, but I manually installed it into the project and it resolved the issue.
