问题描述

Xcode11 beta5中swiftUI的Path.fill和.stroke不起作用

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

下面的代码在Xcode beta4中工作正常，但在Xcode beta5中崩溃，我得到的所有错误信息都是:线程1:EXC_BAD_INSTRUCTION(代码= EXC_I386_INVOP，子代码= 0x0)

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)

代码:

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
