SwiftUI - Text minimumScaleFactor not scaling only when needed

Question

I have a Text that I want to modify with a .minimumScaleFactor(0.1) when the length of its string extends outside the view. However, the scaling applies every time, even when the original font size would be perfectly fine.

My view is structured thusly:

        VStack(alignment: .center, spacing: 0) {
            HStack {
                Image("medal \(place)").resizable()
                    .foregroundColor(color)
                    .frame(width: 40, height: 40)
                Spacer()
                Text(username)
                    .font(.bold(16))
                    .lineLimit(1)
                    .minimumScaleFactor(0.1)
                    .frame(alignment: .trailing)
                    .foregroundColor(Color("mediumTextColor"))
            }
            Spacer()
            Text(score)
                .font(.extraBold(60))
                .foregroundColor(color)
                .lineLimit(1)
                .minimumScaleFactor(0.7)

            Spacer()
        }
        .frame(height: 96)
        .padding(10)
        .cornerRadius(16)
        .overlay(RoundedRectangle(cornerRadius: 16)
        .stroke(color, lineWidth: 2))

Answer 1

Important for that minimumScaleFactor() only does its job when it is needed, is the combination of .minimumScaleFactor AND .lineLimit(1); otherwise it will not work. layoutPriority(1) is not the key here.

Example - this works; Scale is only applied when needed:

Text("Something").minimumScaleFactor(0.5).lineLimit(1)

Answer 2

A continuation of answer above.

What is important is the order in which the modifiers are applied:

Text("This is a really long sentence.") 
   .minimumScaleFactor(0.5)                
   .font(.custom("OpenSans", size: 15))
   .lineLimit(1)
   .layoutPriority(1)

There isn't a need for the GeometryReader unless you need it for something else

Answer 3

Adding .lineLimit(1) to the Text will work well.
