FR: Background Thread Crashlytics Initialization

[michaeleisel]

Feature proposal

• Firebase Component: Crashlytics

My recollection is that Crashlytics at some point in the past could be initialized on a background thread. However, I see that currently it's recommended to call [FIRApp configure] on a background thread. Considering that Crashlytics by itself can take 50ms+ during startup, I'd love to be able to initialize it on a background thread. This would also be a big advantage over other crash reporters that have a similarly high main thread delay.

Hi @michaeleisel,
We've implemented some improvements in #7332 to speed up the startup time of the SDK. This doesn't move the initialization to the background thread, but should help a little with the delay.

👍 any ballpark estimates on the reduction?

From some testing on an iPhone 7 running iOS 14.3, I saw a decrease of more than 50% in SDK start up time. Of course, this is an old phone and the improvements will definitely vary by device and application size.

sounds great. it'd still be nice to have thread safety, but certainly less important. could close or not 🤷

I'll close this for now and reopen if there are any updates.
