swiftui - Path.fill in Xcode11 beta5 doesn't work anymore

Question

Path.fill and .stroke of swiftUI in Xcode11 beta5 doesn't work

The code below works fine in Xcode beta4, but it crashes in Xcode beta5, the error information all I get :Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode = 0x0)

Code :

import SwiftUI

struct ContentView: View {
    var body: some View {
        Path{path in
            path.addRect(CGRect(x: 20, y: 20, width: 300, height: 200))
        }.fill(Color.red)
    }
}

#if DEBUG
struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
#endif

It's a known issue in Beta 5. Disclosed in their release notes:

Using the Path structure may cause your app to crash if you’re using the SDKs included in Xcode 11 beta 5. As a result, you may be unable to successfully follow the steps in the Drawing Paths and Shapes tutorial. (53523206)
