Gfx device initialization failed

[stein84]

I'm using Firebase SDK 1.1.1 and Unity 5.3.6f1. Xcode 8.2.1 and iOS environment.
(device - 5 with iOS 9.2.3 , 6 plus with 10.1)
When libMessaging.a included in my project, the app crashes with 'gfx device initialization failed' message.
It's pretty odd that Firebase affects GL initialization but it happens. When building after removing libMessaging.a, this issue never occurs.
quickstart sample won't reproduce this issue, but there's no difference between my project settings and sample's one and it seems I'm not the only person who suffers from this, due to this link below

followings are logs from both quickstart sample and my project.

any advice on this ? thanks

The log points to applicationDidFinishLaunching() not being called before applicationDidBecomeActive(). applicationDidBecomeActive is one of the methods we swizzle when libMessaging.a is loaded. It's possible our method swizzling is interacting with another plugin in your project. Any chance you could try pulling plugins from your project into the quickstart sample one at a time to see which one causes this to break?

I believe we finally tracked this down to using a C++ object before the C++ runtime was initialized (i.e during an Obj-C +load() method). The fix should be in the 3.0.0 release https://firebase.google.com/support/release-notes/unity#3.0.0
