layerIndex Property Throws Error/Not Adding Layers In Correct Order

[dmlitvinov]

We have exactly the same problem. There is no error without specifying an index, but there is no way to set the correct layer order

Is this layer index property working for anybody else?

I just stumbled across the same issue - but only on iOS.
Android is fine with setting the `layerIndex´ prop.

The crash seems to happen here. I don't know why the style apparently have no layers when running on iOS. I tried to set layerIndex after a delay when the map and all layers have rendered, but it crashes immediately when setting the prop.

As a workaround, I used the aboveLayerID (belowLayerId could be used as well I suppose), for all my layers, even though they are not in the same ShapeSource and that works fine for both iOS and Android.

I tried #361 in my project with setting layerIndex instead of aboveLayerId.
The layers in my map style (street names, etc.) are placed rather high up with the highest being around layerIndex 40-42.
I want my own layers to be placed above all the map's own layers, so if I set layerIndex to 50 for my own layer, I get:
Terminating app due to uncaught exception 'NSRangeException', reason: 'Cannot insert style layer at out-of-bounds index 50.
I have 14 layers on my map, so I have to use the 8 indexes between 42 and 50, and rely on aboveLayerId layers in the same ShapeSource.

Does anyone know why it is not possible to use an index >= 50?
