How to fix “Cannot convert value of type 'String' to expected argument type 'Binding<String>’”

SwiftUI’s components expect to have two-way bindings to properties, using something like @State or @ObservedObject. This error occurs because you tried to create an interactive component without a binding, such as this:

TextField("Enter your name", text: name)

To fix this, make sure your property is marked with @State, like this:

@State private var name = ""

Now create your component using a two-way binding, like this:

TextField("Enter your name", text: $name)
