iOS: FIRApp.configure() on a thread other than the main thread

[sri...@laddoo.net]

Is it safe to call FIRApp.configure() on a thread other than the main thread in iOS? I'm using Firebase for analytics and crash reporting and might use it for push notifications in the future. The initial call takes ~30ms and I'd like to keep that out of the init loop for faster app load times. I couldn't find any details about this in the documentation.

Thanks!

Hello Sridhar,

Great questions. From what I can tell, FIRApp and Firebase Analytics are both built to be thread safe on iOS. We can't see any immediate issues here, but I don't think this has been tested widely and there could be gaps in some of the specific feature modules. For example, I recall that we had an issue during initial launch, fixed now, when Crash Reporting was used beside SQL Lite, because it was not concurrency safe.

☼, Kato
