Description

Very frequently, after building an app to the iOS Simulator I see no logs:

But when I open the file mentioned in the second last line it does exist and has logs:

Yeah this should be fixed in the current master , it was to do with compile time logs being lost.

[~fokkezb] check this out see if we can close this ticket?

Hard to say since it doesn't always happen, but TIMOB-20588 talks about main thread (which I don't have enabled) and Studio (which I don't use)
Angel Petkov 2016-04-08

Main thread shouldn't be enabled , for the fix to work. Its just the one method thats we forced to run on main-thread so the logs don't get lost. The logging messages on compile time shouldn't be an issue now, did you test it with 5.4.0 ? You don't need to have studio open to test this.

Yes, seems to work. Notice the first line of 5.4 missing with 5.2.2 5.2.2
