@jhoanarango, can you provide additional information/ a code snippet of what is happening in your code when you receive that message?

Hello,

So there is not code snippet that I can't point to from my code, however following this trace it leads me to MapBox's EventsManager.sendTurnstile(). I will post screenshots here, since it seems is the best way to show you. Also, I am on XCode Beta 5 now.

@jhoanarango Were you able to find a fix for it? I'm seeing the exact same thing as you. CC: ZiZasaurus

@srinivaskasala , hey sorry I didn't answer earlier. But not, till this day I have not been able to do anything about this. I think this is more on the MapBox side. They should take a look since I do not have access.

@jhoanarango @srinivaskasala Here is the PR with the fix: https://github.com/mapbox/mapbox-events-ios/pull/344 It was released as part of MapsSDK 10.8. There are some cases when you still can see this issue but I can assure you that aside from the Xcode warning, this problem has no impact on the stability of the SDK. It was blocking the main thread for a small amount of time, but it happens only during the MapView initialization as you can see from the stack trace, so it doesn't affect the map after it has been created.
