如何删除视图的默认边距，SwiftUI？

Question

I'm new to SwiftUI. According to my picture below, there are leading and trailing margins appeared in my DialogView(white area at bottom). I need to remove it.

Here's my code.

struct ForgetPasswordView: View {
var body: some View {
    ZStack {
        VStack {
            HStack {
                Image("img_test").resizable()
                    .frame(width: 100, height: 100)
            }
            .frame(height: 130)
            .frame(maxWidth: .infinity)
            
            Spacer()
            DialogView()
                .background(Color.white)
                .frame(maxWidth: .infinity)
        }
        .padding(.top, 120)
        .background(Color.pink)
    }
    .edgesIgnoringSafeArea(.all)
    }
}

struct DialogView: View {
var body: some View {
    VStack(alignment: .leading, spacing: 30) {
        Text("Forget Password")
            .font(.system(size: 15, weight: .light))
            .padding(.top, 20)
        Text("Proceed to reset your password? ")
            .font(.system(size: 15, weight: .light))
        Text("If yes, please enter your existing mobile number to receive OTP")
            .font(.system(size: 15, weight: .light) )
    }
    }
}

Answer 1

I assume that want to keep the background of the DialogView to ignore the safe area but keep its content within the safe area.

In this case use a ZStack with a fixedSize modifier like this:

struct DialogView: View {
    var body: some View {
        ZStack {
            Color.white
                .ignoresSafeArea()
            VStack(alignment: .leading, spacing: 30) {
                Text("Forget Password")
                    .font(.system(size: 15, weight: .light))
                    .padding(.top, 20)
                Text("Proceed to reset your password? ")
                    .font(.system(size: 15, weight: .light))
                Text("If yes, please enter your existing mobile number to receive OTP")
                    .font(.system(size: 15, weight: .light) )
            }
        }
        .fixedSize(horizontal: false, vertical: true)
    }
}

Also, you'll need to remove existing .background and .frame that you add in the parent view and embed it just like DialogView() .
