I have error: Cannot convert value of type 'Binding<String>.Type' to expected argument type 'Binding<String>'

I am using Xcode version 12.3, swift 5 and iOS 14.3

Occurred when grouping static containers (TextField and Text)

struct ContentView_Previews: PreviewProvider {

static var previews: some View {

ContentView(text: Binding<String>) // error is here

}

}

How can I solve this ?

That depends on how you defined your ContentView.

You can try something like this:

Code Block struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView(text: .constant("test value")) // <-
    }
}

When your ContentView have an @Binding property named text of type String, you need to pass an instance of Binding<String>, not the type name of itself.
