ios – SwiftUI looping through an array of Any using a ForEach – Type ‘any ‘ cannot conform to ‘Identifiable’

I’ve created a protocol as follows:

protocol InputViewModel: ObservableObject, Identifiable {
    var id: UUID { get }
    var title: String { get }
    var shouldShowTitle: Bool { get }
    var data: String { get set }
    var placeholder: String { get }
    var fieldType: FieldType { get }

Using this protocol, I’ve created types like TextFieldViewModel, TextViewViewModel, DatePickerViewModel etc

In my SwiftUI view, I have a list which could have any input type so I have an array as follows:

private(set) var inputViewModels: [any InputViewModel] = []

I populate this with required view models.

Now in my SwiftUI view, I want to loop through these view models and build the UI so I do this:

List {
    ForEach(currentProjectViewModel.projectInfoViewModels) { inputViewModel in
        if let inputViewModel = inputViewModel as? TextFieldRowViewModel {
            createUI(inputViewModel: inputViewModel)

This is where I get the error Type 'any InputViewModel' cannot conform to 'Identifiable'

SwiftUI error looping to any type

I know one way to fix this would be to make the inputViewModels of a specific type so that would be private(set) var inputViewModels: [InputViewModel] = [] without the use of any, however, I do have the requirement to support any input type.

Another solution would be to use indices as follows

ForEach(currentProjectViewModel.projectInfoViewModels.indices, id: \.self) { index in
    let viewModel = currentProjectViewModel.projectInfoViewModels[index]
    if let inputViewModel = viewModel as? TextFieldRowViewModel {
        createUI(inputViewModel: inputViewModel)

However, I’ve heard that using indices is not really reliable in SwiftUI views and as much as possible we want to iterate over the object

I also came across this answer but it is similar to the first solution I pointed out here.

How could I achieve what I want in the simplest / cleanest way possible ?
