Answer 1

Having the same exact issue with iOS 10.3 and Xcode 8.2.1. I'm not going to download the new Xcode beta just to fix this. Come on Apple!

To anyone reading this, you have to go to https://developer.apple.com/download/ and get the latest version, which might even be the beta, if the stable release doesn't work.

In the future, I would be aware if you update iOS on your devices you may break Xcode/iOS version so update wisely if you want to keep testing on it without jumping through hoops that Apple makes.
