Application crashes when adding a heatmap layer type

[captainbarbosa]

Steps to reproduce

1. Create a heatmap layer and add it to a map view after the style has finished loading:

func mapView(_ mapView: MGLMapView, didFinishLoading style: MGLStyle) {
    // Parse GeoJSON data. This example uses all M1.0+ earthquakes from 12/22/15 to 1/21/16 as logged by USGS' Earthquake hazards program.
    guard let url = URL(string: "https://www.mapbox.com/mapbox-gl-js/assets/earthquakes.geojson") else { return }
    let source = MGLShapeSource(identifier: "earthquakes", url: url, options: nil)
    style.addSource(source)

    // Create a heatmap layer.
    let heatmapLayer = MGLHeatmapStyleLayer(identifier: "earthquakes", source: source)
    style.addLayer(heatmapLayer)
}

Full minimal test case can be found here.

2. Try to run this code in an application and observe crash.

Expected behavior

• Application should not crash and heatmap should render.

Actual behavior

• Entire application crashes with the following log:

libc++abi.dylib: terminating with uncaught exception of type std::runtime_error

Configuration

Mapbox SDK versions: v5.1.0-alpha.1 iOS/macOS versions: 10.14.4 Device/simulator models: iPhone X, physical device Xcode version: 10.2.1

I'm getting this issue in 5.2. Any workaround?

@long1eu Did you ever find a solution? I'm encountering this issue when I add a heatmap on iOS only. Android works fine, I'm using the react-native version of this library (current react native version uses the 5.9.0 iOS SDK)

Gotcha. Thanks for the quick reply!
