ViewModifier

A ViewModifier is a protocol that can be called on a particular view. Modifier methods adhere to the protocol and return a new, altered View that will replace the originally created View.

struct MyView: View {
    var body: some View {
        View(s) here
            Modifier methods like .bold() can be called underneath a View.
            Multiple modifiers can be chained using dot notation.
    }
}

The following example displays some text:

import SwiftUI

struct ContentView: View {
    var name: String = "Sam"

    var body: some View {
        Text("Hello \(name)")
            .font(.title)
            .bold()
    }
}

In the example above, the .font() and .bold() modifiers are called on a Text view. In addition, a built-in text style, .title property, is passed into the .font() modifier.

This will display:
