Ios SwiftUI 中的偏移量和按钮有问题吗

我有一组按顺时针方向旋转的按钮，但我无法正确单击它们:

我认为补偿有问题，但我不知道如何解决，有什么建议吗？

这是代码:

struct CategoryView: View {
    // Circle Radius
    @State private var radius: Double = 150
    let circleSize: Double = 350
    // Degree of circle
    @State private var degree = -90.0
    let cards = ["John", "Mark", "Alex", "Kevin", "Jimmy"]
    
    var body: some View {
        ZStack {
            let anglePerCount = Double.pi * 2.0 / Double(cards.count)
            ForEach(0..<cards.count, id: \.self) { index in
                let angle = Double(index) * anglePerCount
                let xOffset = CGFloat(radius * cos(angle))
                let yOffset = CGFloat(radius * sin(angle))
                Button {
                    
                } label: {
                Text(cards[index])
                    .font(.title)
                    .fontWeight(.bold)
                    .rotationEffect(Angle(radians: angle + Double.pi/2))
                    .offset(x: xOffset, y: yOffset)
                }
            }
        }
        .rotationEffect(Angle(degrees: degree))
        .onAppear() {
            radius = circleSize/2 - 47 // 47 is for padding
        }
    }
}
