Firebase，Fabric和Crashlytics与-ObjC链接器标志没有Cocoapods iOS

Question

Trying to add Firebase Messaging to my iOS app that already has Fabric/Crashlytics and I am trying to add it without Cocoapods .

I followed the readme instructions in the Firebase SDK zip file and once I add the -ObjC linker flag to the target, it causes a duplicate symbol compile error for Fabric/Crashlytics

I then found out to use -force_load and pointed it to the Firebase.h file. This allowed me to compile, but when trying to FIRAPP.configure() it came up with this error:

2016-11-30 14:33:31.862 Parents[243] <Debug> [Firebase/Core][I-COR000001] 
    Configuring the default app.

    unrecognized selector sent to class 0x3159a53c

Has anyone ever experienced this before? Please note I am not using Cocoapods for all three.

Answer 1

I actually had the same exact problem. My awesome coworker suggested to update Fabric and Crashlytics to the latest and it worked. Try that!
