[FIRApp configure] crashes app on ios simulator

[mjmaix]

• Xcode version: Version 9.0 (9A235)
• Firebase SDK version: Firebase/Core (4.3.0)
• Firebase Component: Core
• Component version: _____

Steps to reproduce:

Running my RN app with react-native run-ios is working until integrating firebase on ios/AppDelegate.m file. After adding, the app crashes after showing (> 1 sec)

(did pod update and/or pod install after manually removing Pods folder)

See this this recording: http://recordit.co/Ry74pTUpmC

I'm using iPhone 6 (iOS 11.0) simulator

This is the system log

Hey @mjmaix - instead of import <Firebase.h> try import <Firebase/Firebase.h>. Let me know how that goes!

[mjmaix]

@ryanwilson

Thank you for checking. Just tried #import <Firebase/Firebase.h> with react-native run-ios but it's still now starting as expected

Hmm thanks for trying. Is there anything above that in the log about where in the process it fails? I haven't used React Native before so trying to figure out where this is failing.

[mjmaix]

None, cause I cleared the system log before `react-native run-ios`. Do you want to see the startup logs? It's quite long though

If you could share the stack trace where it crashes from the system log, that'd be great! I guess this can be done like this (apologies if you already knew this, I'm learning this as we go 😛 )

[mjmaix]

Tried but it doesn't get me thru when clicking cmd+D as the app shows then crashes.. I'm not an iOS dev so I don't know other tricks to start the app in debug mode

[mjmaix]

I'll also check this more tomorrow, I'll post updates

[ryanwilson]

Looks like you should still be able to grab them from the simulator log (from this comment:

tail -100 -f ~/Library/Logs/CoreSimulator/{simulator udid}/system.log

Should grab the last 100 lines of the log. If you have more than one simulator, you can get the UDID by running instruments -s devices.

Sounds good, keep me in the loop!

I did some experiments by creating xcode project with firebase pod install. It's not crashing like in react-native. Maybe this is not a problem on firebase-ios-sdk?

[mjmaix]

Fixed it, I opened the project on xcode using .xcworkspace, run the app
By doing this, the logs would remain even after the app crashed.

*** Terminating app due to uncaught exception 'com.firebase.core', reason: '`[FIRApp configure];` (`FirebaseApp.configure()` in Swift) could not find a valid GoogleService-Info.plist in your project. Please download one from https://console.firebase.google.com/.'

Missing GoogleService-Info.plist
Apparently, I have to use Xcode's Add files to project instead of copy pasting it on the folder.

@mjmaix thanks for the update, glad you figured it out!
