Display specific parts of an array ? [SwiftUI]

Question

I have an empty array var choosenData = [Choosen]() By tapping a button, I append myView() component inside this array (component stored in another array)

self.choosenstore.choosenarray.append(
    Choosen(value: self.collectionarray[index].value)
)

And I would like to display this array like this:

HStack {
    ForEach(choosenstore.choosenarray) { choosen in
        myView(myValue: choosen.value)

    }
}

But on multiple lines. I tried multiple solution I saw on StackOverflow and other but it didn't work. So maybe is it possible to like do a "ForEach(choosenstore.choosenarray between 0 and 4 )" then a "ForEach(choosenstore.choosenarray between 4 and 8 )" ect... ?

Thanks !

It's an array. So you can deal with it like a normal array in Swift. Something like:

    HStack {
        ForEach(
            choosenstore.choosenarray
                .enumerated()
                .filter { (4...8).contains($0.offset) } // Here is the filter for being between 4 and 8
                .map { $1 }) { choosen in
            myView(myValue: choosen.value)
        }
    }
