How to make width of view equal to superview in SwiftUI

Question

I have Button

struct ContentView : View {     var body: some View {         HStack {             Button(action: {}) {                 Text("MyButton")                     .color(.white)                     .font(Font.system(size: 17))             }             .frame(height: 56)             .background(Color.red, cornerRadius: 0)         }     } } 

But I want to pin it to supreview's edges (trailing to superview's trailing and leading). Like this:

HStack doesn't help me, and it's expecting. Fixed frame or width equals UIScree.size are not flexible solutions.

Answer 1

You need to use .frame(minWidth: 0, maxWidth: .infinity) modifier

Add the next code

        Button(action: tap) {             Text("Button")                 .frame(minWidth: 0, maxWidth: .infinity)                 .background(Color.red)         }         .padding([.leading, .trailing], 20) 

Padding modifier will allow you to have some space form the edge.

Keep in mind that the order of modifiers is important. Because modifiers are actually functions that are wrapping the view bellow(they do not change a properties of views)
