iOS 13, Metal on simulator, CIKernel

Hey there,

I am very happy to see that iOS 13 seems to have Metal supported on simulator.

I am wondering however, why using a CIColorKernel with deprecated Kernel Language works fine but a CIKernel (and the proper options in Build Settings) works fine on device but not on simulator. I get the following issue : "Metal DAG compiler disabled"

Hope to get some help on this.
