Ok, here's what happened. To open the project in XCode 11 I had to convert Swift from 3.x to 4.x. When I made some manual changes to add the @objc tag, I errantly added it to a few private functions in the code. I'm guessing the 'out of range' message meant 'hey, we can't see those functions you idiot.I removed it and now builds fine on all devices & ios versions.Hopefully this helps someone in he future...
