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
