In swiftui is there a way to pass a field of a propertywrapper that is an object, to a Binding parameter

Using Swift
1

I have a View that takes a Binding field of type String. I would like to pass the field of a propertywrapper that is an object. Is this possible?

@Binding var commentDto: CommentDto? // has a field called text
var body: some View {
    CustomTextField(text: $commentDto.text) // this gives error as field text, of $commentDto, is not available when using wrapper
}

Assuming that CommentDto looks something like this:

struct CommentDto {
  var text: String
}

then $commentDto.text will be Binding<String>, which I assume is not what you want. If you just want a String, you can do commentDto.text (no $).

PS

As per API design guidelines, it should be CommentDTO.

That is what I want actually, Binding<String>. But because the commentDto is optional compiler will not allow me to call $commentDto.text.

See this initializer. It allows you to provide custom closures that are called in order to get and set the value of the binding.
