"no such layer" exception after style update

[tadasr]

Platform:
iOS

Mapbox SDK version:
ios-v3.3.4 (c64a0c2486)

Steps to trigger behavior

We released our app 7 days ago. After we updated updated our map style(2 days ago) we started to receive crashes (from Crashlytics) with error "Fatal Exception: std::runtime_error: no such layer".

we are calling insertCustomStyleLayerWithIdentifier on mapViewDidFinishLoadingMap delegate callback. We are removing layer with removeCustomStyleLayerWithIdentifier on willMoveToWindow callback if window is nil.

Some stack trace:

Fatal Exception: std::runtime_error: no such layer

Could you post a fully symbolicated stack trace, please?

[1ec5]

Just a wild guess, based on the error message: are you sure the otherIdentifier parameter is correct? It should be the identifier of a layer that’s already in the style. You can see a list of the layer identifiers in Studio’s sidebar. (Once #6097 lands, you’ll also be able to access this list via MGLStyle’s layers property.)

@1ec5 I just double checked, otherIdentifier is correct.

That was fun to read on my phone. 😀 (Please use Gist next time.) The stack trace still says "hidden" all over it, which means it isn't symbolicated.

The only place that the "no such layer" exception thrown is in Style::removeLayer (within the implementation of removeCustomStyleLayerWithIdentifier). Are you absolutely sure that you are passing the correct layer identifier to removeCustomStyleLayerWithIdentifier, and calling it only when the custom layer has not already been removed?
