Summary:
I attached an implementation of an MKOverlayRenderer to this report. This renderer is used in our app to render a track on a MKMapView. This works with iOS 9.x, but does not work with iOS 10 beta 1.

There are also some warning logs of VectorKit:
2016-06-14 15:00:40.158864 CURFER[273:15886] [LogMessageLogging] <private>
ERROR /BuildRoot/Library/Caches/com.apple.xbs/Sources/VectorKit/VectorKit-1208.4/GeoGL/GeoGL/GLCoreContext.cpp 1760: InfoLog SolidRibbonShader:
ERROR /BuildRoot/Library/Caches/com.apple.xbs/Sources/VectorKit/VectorKit-1208.4/GeoGL/GeoGL/GLCoreContext.cpp 1761: WARNING: Output of vertex shader 'v_gradient' not read by fragment shader

Steps to Reproduce:
Use the attached Renderer to render something on a MKMapView.

Expected Results:
The render should do it's job as it does in iOS 9.

Actual Results:
No rendering at all, warning logs (see above)

Version:
iOS 10.0 [14A5261v]

Configuration:
