Starting with iOS 13 the simulator now supports Metal but without Metal Performance Shaders.

If you want to run GPUImage3 on the simulator you can change this:

if #available(iOS 9, macOS 10.13, *) {
    self.metalPerformanceShadersAreSupported = MPSSupportsMTLDevice(device)
} else {
    self.metalPerformanceShadersAreSupported = false
}

to the following:

#if targetEnvironment(simulator)
    self.metalPerformanceShadersAreSupported = false
#else
    if #available(iOS 9, macOS 10.13, *) {
        self.metalPerformanceShadersAreSupported = MPSSupportsMTLDevice(device)
    } else {
        self.metalPerformanceShadersAreSupported = false
    }
#endif

According to Developing Metal Apps that Run in Simulator:

In Xcode 11, Simulator adds support for Metal development. You can write iOS and tvOS apps that use Metal and test them in the Simulator, gaining the benefits of hardware acceleration on the Mac during development of your app.

and Supporting Simulator in a Metal App

I guess this crash related to framework GPUImage3, but..I tried to run the code from Apple. The app crashes, unfortunately.

updated: MetalPerformanceShaders is not supported on the simulator currently.
