Display a Float with specified decimal places in SwiftUI

I am trying to display the value of a Slider in SwiftUI, but I only want one decimal place to show.

I know how to do this in regular Swift by using "%.1f", but that does not work in SwiftUI.

Solution

  • There is nothing special to do about SwiftUI:

    struct ContentView : View {
    let myfloat: Float = 1.2345    

    var body: some View {
        let formattedFloat = String(format: "%.1f", myfloat)
        return Text("My Float: \(formattedFloat)")
    }
}
