Can't create binding in TextField - 'cannot find $social' in scope'

I can't create a binding with my 'username' property - Xcode gives me the error 'cannot find $social in scope'. Here is some of the essential code:

My problematic view:

struct ProfileSetter: View {
    @Binding var profile: Profile
    
    var body: some View {
        ForEach(profile.socials, id: \.id) { social in
            TextField(social.medium.rawValue, text: $social.username) //-> cannot find $social in scope
        }
    }
}

Its parent:

struct ProfileView: View {
    @StateObject private var viewModel = ViewModel()
    
    var body: some View {
        ProfileSetter(profile: $viewModel.myProfile)
    }
}

The simplified view model:

class ViewModel: ObservableObject {
    @Published var myProfile = Profile(socials: [//multiple instances of Social])
}

And finally, the models:

struct Profile {
    // other properties
    var socials: [Social]
}

struct Social {
    // other properties
    var username: String
}

Replacing the text field with Text(social.username) works fine, so creating the binding seems to be the problem.

You cannot bind directly to value, you should do it via parent object, like

ForEach(profile.socials.indices, id: \.self) { index in
    TextField(profile.socials[index].medium.rawValue, 
        text: $profile.socials[index].username)
}
