React-native-firebase: App does not start if I add the stuff to AppDelegate.m

[ODelibalta]

When I add those two lines to AppDelegate.m, simulator fires up and nothing happens after that.

Environment

1. Target Platform iOS:
2. Development Operating System macOS Sierra:
3. Build tools (Xcode: Version 8.3.3 (8E3004b), iPhone 6 ios 10.3):

"scripts": {

    "test": "jest"

  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  [FIRApp configure];
  return YES;
}

Anything in the xcode logs?

How do I find that? I open xcode window> devices and selected iphone6 (simulator uses that) but there is nothing about logs.

I am about to lose it. It's been two days I've been trying to get this to work. I downloaded the example app from here and guess what, that works. When I do the steps, it does not.

I figured out and it was my mistake. I was copying the .plist file via finder. I added the file to the project within xcode. everything works now. I literally spent my entire weekend for this. I do not feel too highly of myself right now :) please close. ty !
