My app has several app extensions and I'd like to be able to unify the logging between them such that they write to a single shared file (which can be read from and subsequently uploaded to things like Crashltyics or Bugsnag etc.)
Its possible to log directly to things like Crashlytics, however none of them I've investigated have a unified approach for the app and extensions (for example, if you use Crashlytics you have to configure the app and the extensions separately, so any logging goes to two entirely separate consoles.)
Hence, instead I'm wondering if there a library that provides the ability to log to a file, and that file can be shared and simultaneously written to (in the case where the app and its extensions are running simultaneously).
Do any of the existing log libraries for iOS have this ability?
