SwiftUI stop Divider from expanding vertically in HStack

I'm using SwiftUI to create something like an alert popup, which I present from UIKit code using UIHostingController. The view looks like this:

VStack(spacing: 0) {
    // Some text ...   

    HStack(spacing:0) {
        Button(action: self.onCancel) { Text("Cancel") }
           .padding().inExpandingRectangle().fixedSize(horizontal: false, vertical: true)

        // This divider is the problem
        Divider() // .fixedSize()

        Button(action: self.onDelete) {  Text("Delete") }
           .padding().inExpandingRectangle().fixedSize(horizontal: false, vertical: true)
    }
}.frame(minHeight: 0)

The inExpandingRectangle is something I found in another stackoverflow question. It centers the text in each side of the HStack.

extension View {
    func inExpandingRectangle() -> some View {
        ZStack {
            Rectangle().fill(Color.clear)
            self
        }
    }
}

It looks like this. Garbage.

If I put the .fixedSize() on the divider, it does this. Not horrible, but the divider is stupid looking and doesn't expand to the size of the buttons.

Here is a demo of possible simplified alternate, without that artificial extension. Tested with Xcode 11.4 / iOS 13.4.

demo

Divider() // or Rectangle().fill(Color.gray).frame(height: 1)
HStack {
    Button(action: {}) { Text("Cancel").fixedSize() }
        .padding().frame(maxWidth: .infinity)

    Divider() // or Rectangle().fill(Color.gray).frame(width: 1)

    Button(action: {}) {  Text("Delete").fixedSize() }
        .padding().frame(maxWidth: .infinity)

}.fixedSize(horizontal: false, vertical: true)

Note: It worth also to consider custom divider, like

Rectangle().fill(Color.gray).frame(width: 1) // or any other color

than might give much appropriate visual feedback, like

Putting a fixedSize() modifier on the HStack instead of the Divider fixies the problem.

    var body : some View {
        VStack(spacing: 0) {
            // Some text ...
            Text("gsfdsfkajflkasdjflkas,jdflaskjf")
            HStack(spacing:0) {
                Button(action: {print("hi")}) { Text("Cancel") }
                    .padding().inExpandingRectangle().fixedSize(horizontal: true, vertical: true)

                // This divider is the problem
                Divider()


                Button(action: {print("hello")}) {  Text("Delete") }
                    .padding().inExpandingRectangle().fixedSize(horizontal: true, vertical: true)
            }.fixedSize()        <------- Insert this
        }.frame(minHeight: 0)
    }

Result:

You can try below code hope its help you (Xcode 11.2.1)

Note: Change Font, Frame and Color as per your requirement

var body: some View {

    VStack(spacing: 0) {

        Text("Delete")
            .font(Font.system(size: 20, weight: .bold))

        Text("Are you sure you want to delete ?")
            .font(Font.system(size: 18, weight: .regular))
            .padding([.top,.bottom], 15)

        Rectangle().fill(Color.gray.opacity(0.5)).frame(height:0.5)

        HStack(spacing:0) {

            Button(action: {
                //Your action
            }) {
                Text("Cancel")
                    .foregroundColor(Color.black)
                    .font(Font.system(size: 18, weight: .medium))
            }
            .frame(minWidth: 150, maxWidth: .infinity, minHeight: 40, maxHeight: 40, alignment: .center)

            Rectangle().fill(Color.gray.opacity(0.5)).frame(width:0.5,height:20)

            Button(action: {
                //Your action
            }) {
                Text("Delete")
                    .font(Font.system(size: 18, weight: .medium))
                    .foregroundColor(Color.red)
            }
            .frame(minWidth: 150, maxWidth: .infinity, minHeight: 40, maxHeight: 40, alignment: .center)
        }
    }
}

Output :
