        I run my app whit a MKMapView and the console show this:

         

        "ERROR /BuildRoot/Library/Caches/com.apple.xbs/Sources/VectorKit_Sim/VectorKit-1230.32.8.29.9/GeoGL/GeoGL/GLCoreContext.cpp 1763: InfoLog SolidRibbonShader:

        ERROR /BuildRoot/Library/Caches/com.apple.xbs/Sources/VectorKit_Sim/VectorKit-1230.32.8.29.9/GeoGL/GeoGL/GLCoreContext.cpp 1764: WARNING: Output of vertex shader 'v_gradient' not read by fragment shader"

         

        What happened?

         

        Help, please.

            Can you describe a bit more about the map related code in you app?  Custom annotations?

             

            -M

                  Hello have simple Map in C-Objective..

                   

                  MKCoordinateRegion myRegion;
                    
                       CLLocationCoordinate2D center;
                      center.latitude = DUB_LAT;
                      center.longitude = DUB_LONG;
                    
                      MKCoordinateSpan span;
                      span.latitudeDelta = THE_SPAN;
                      span.longitudeDelta = THE_SPAN;
                    
                      myRegion.center = center;
                      myRegion.span = span;
                     [mapView setRegion:myRegion animated:NO];
                  

                   

                  Pretty standard .. but this error comes when Try to zoom or interect with map in any way..

                      I experienced the same bug on Version 8.2 (8C38) on a Swift project, it makes the app crash on a real device but just warns on the simulator

                       

                      ERROR /BuildRoot/Library/Caches/com.apple.xbs/Sources/VectorKit_Sim/VectorKit-1230.32.8.29.9/GeoGL/GeoGL/GLCoreContext.cpp 1764: WARNING: Output of vertex shader 'v_gradient' not read by fragment shader
                      
                      
                      
                      
                      

                       

                       

                      Just on one scene using a map but the issue dissapeared when I stopped displaying an info message with https://github.com/SwiftKickMobile/SwiftMessages

                       

                      Just saying it could be an interaction between the mapkit and a 3rd party library

                       

                      Hope it helps

                    I get this also, just dragged a MapView in interface builder into my app, and when I zoom I get this in the logs...

                      I have the same messages. Is there any decision to solve the problem?
