Crash when adding and removing the same StyleLayer at runtime

[rmnblm]

Platform: iOS
Mapbox SDK version: 3.4.0-alpha.4

Steps to trigger behavior

1. Add a style layer

// Note: StyleLayer is a class variable
styleLayer = MGLCircleStyleLayer(layerIdentifier: "test-layer", sourceIdentifier: "sv")!
styleLayer.circleColor = UIColor.green
mapView.style().add(styleLayer)

1. Add a UISwitch which basically triggers the following

if (switch.isOn) {
    mapView.style().add(styleLayer)
} else {
    mapView.style().remove(styleLayer)
}

1. Removing the layer works, re-adding the layer will crash the app with the following error message:

Note: I also deleted the latitude, longitude and zoomLevel attributes from the MGLMapView control and also tried to programmatically add the mapView as proposed from @1ec5 in #1184, still doesn't work.

This is due to a combination of #6254 and #6096. For now, you'll need to get a fresh reference to the layer after adding it, using layerWithIdentifier(_:).

Thank you, I wasn't sure if I'm doing something wrong or it isn't supported yet. I implemented an example in my Mapbox-iOS-Examples repo here.
