Answer 1

Initializer 'init(value:total:)' requires that 'Binding<Int>' conform to 'BinaryFloatingPoint'

Thanks for showing the error message. That will help readers find what's happening in your code.

The initializer of ProgressView you are trying has this signature:

Code Block init<V>(value: V?, total: V = 1.0) where Label == EmptyView, CurrentValueLabel == EmptyView, V : BinaryFloatingPoint

The value passed to value: needs to be of some type BinaryFloatingPoint, not Binding nor Int.

Code Block struct ContentView: View {
    @State private var progress: Double = 0 //<- A type conforming to `BinaryFloatingPoint`
    
    var body: some View {
        ProgressView(value: progress) //<- No `$` here
    }
}

What do you mean by will not work?

If your code causes build time errors, you should show all the error messages.
If your code causes runtime errors, you should include all the error info as well as all the steps to reproduce the error.
If your code runs without errors but generates unexpected results, you need to clarify what you expect, what you actually get and how you can reproduce the issue.
