I know there are lots of posts on this error and it seems like it is a catchall for Xcode. I have tried all the suggestions in these posts:
Installation Failed "Invalid argument" when trying to run Today application extension
Installation Failed: Invalid Argument -iOS Extension
https://forums.developer.apple.com/thread/7338
And none of them have worked (I tried every answer's suggestion). I have reverted to older commits that I know never saw this error, done clean clone installs, I uninstalled and reinstalled Xcode, restarted my computer, deleted all derived data, and everything else I could possibly think of. Please let me know if you think you have an answer.
Note: I still think there may be an issue with the info.plist, but like I said, even reverting back to an older version doesn't work. Is there potentially a place xcode keeps info.plist files on the local hard drive and references these?
Thanks!
