I have configured the Firebase Crash Reporting. When I test it with code:
NSArray *array = @[@(123),@(312)];
I tested this scenario and it worked fine for me. let me explain it in to steps.
NSArray *array = @[@(123),@(312)]; array;
add the code in application:didFinishLaunchingWithOptions function and after that build the application. It will crash for shower.
Step 2: Stop the application and open the simulator and run the application from the simulator not from Xcode.
// NSArray *array = @[@(123),@(312)]; // array;
comment the code which is causing the crash and run it from the Xcode.
if all work well then this message well shown "Firebase Crash Reporting: Crash successfully uploaded" in the console of Xcode.
Hope it help :) Sorry for bad English. let me know if there is any problem in it.
