Round Specific Corners SwiftUI - iOS 16 Sample Project.swift

struct ContentView: View {
    @State var topLeading: CGFloat = 0
    @State var topTrailing: CGFloat = 50
    @State var bottomLeading: CGFloat = 50
    @State var bottomTrailing: CGFloat = 0

    var body: some View {
        VStack {
            HStack(spacing: 32) {
                Slider(value: $topLeading, in: 0...50)
                Slider(value: $topTrailing, in: 0...50)
            }

            Text("Round me")
                .frame (width: 200, height: 100)
                .background(.red)
                .clipShape(
                    .rect(
                        topLeadingRadius: topLeading,
                        bottomLeadingRadius: bottomLeading,
                        bottomTrailingRadius: bottomTrailing,
                        topTrailingRadius: topTrailing,
                        style: .continuous
                    )
                )

            HStack(spacing: 32) {
                Slider(value: $bottomLeading, in: 0...50)
                Slider(value: $bottomTrailing, in: 0...50)
            }
        }.padding()
    }
}

⚠️ Important Note:

Although it works from iOS 16, .rect needs Xcode 15 to be available.

_{💡 You can use this method until the GM release of the Xcode 15}
