FCM iOS build error

I’ve followed the instructions on http://ionicframework.com/docs/native/fcm/, but no matter what I do, I can’t build for iOS my app with FCM plugin installed. Without it, all works perfectly fine! Here is the error that I get, which doesn’t really give too much useful information to me, any advice will be HIGHLY APPRECIATED! Many thanks!

Don’t your Ionic Native Push Plugin (https://ionicframework.com/docs/native/push/) at the same time, this causes the error!!!
