SwiftUI Custom Slider with max Value

I use this great code to get a slider. here

but how can i set the max value to 30 not to 100?

this example is from 0 to 100.

hope everyone can help.

struct CustomView: View {

@Binding var percentage: Float // or some value binded

var body: some View {
    GeometryReader { geometry in
        ZStack(alignment: .leading) {
            Rectangle()
                .foregroundColor(.gray)
            Rectangle()
                .foregroundColor(.accentColor)
                .frame(width: geometry.size.width * CGFloat(self.percentage / 100))
        }
        .cornerRadius(12)
        .gesture(DragGesture(minimumDistance: 0)
            .onChanged({ value in
                self.percentage = min(max(0, Float(value.location.x / geometry.size.width * 100)), 100)
            }))
    }

You just need to replace the 100 with 30 to get bound from 0 to 30


struct CustomView: View {

    @Binding var percentage: Float // or some value binded

    var body: some View {
        GeometryReader { geometry in
            ZStack(alignment: .leading) {
                Rectangle()
                    .foregroundColor(.gray)
                Rectangle()
                    .foregroundColor(.accentColor)
                    .frame(width: geometry.size.width * CGFloat(self.percentage / 30))
            }
            .cornerRadius(12)
            .gesture(DragGesture(minimumDistance: 0)
            .onChanged({ value in
                self.percentage = min(max(0, Float(value.location.x / geometry.size.width * 30)), 30)
                print(self.percentage)
            }))
        }
    }
}
