Build fails on iOS

[bartonhammond]

First, thanks for sharing this project - looks good!

I have XCode 10.1
Do I need to do anything special?

Launching lib/main.dart on iPhone XR in debug mode...
Xcode build done.                                            8.2s

Hi @bartonhammond ,
I have not tested in Xcode. I tried to follow along plugin guide of flutter (https://flutter.io/docs/development/platform-integration/platform-channels#step-4a-add-an-ios-platform-specific-implementation-using-objective-c. I have no previous experience in iOS dev. May be I missed something. If you find the fix please create a PR.
I am 95% sure, the bug is in this file: https://github.com/hvpulok/flutter_poc/blob/master/ios/Runner/AppDelegate.m
Thanks
