You can add any property to any SwiftUI view, like this:
import SwiftUI
struct ContentView: View {
let name = "Flavio"
var body: some View {
Text("Hello, \(name)!")
.font(.largeTitle)
}
}
See how I used let
because the property is a constant.
Note this, because later we’ll see how to update a property value by tapping a button.
Here is another example with an integer variable:
import SwiftUI
struct ContentView: View {
let name = "Flavio"
let age = 38
var body: some View {
VStack {
Text("Hello, \(name)!")
.font(.largeTitle)
Text("You are \(age) years old")
}
}
}
