display index of each item in forEach loop in swift ui

Question

I wanna display the index of each item in ForEach loop inside SwiftUI views. I tried using an count and increment it everytime but the Xcode gives an error "cannot comform to views"

Hard to know what exactly you are asking about without code but maybe you are looking for [enumerated()](https://developer.apple.com/documentation/swift/array/1687832-enumerated) — Joakim Danielson, Dec 09 '21 at 08:33
Either iterate the `indices` of the array or `enumerate` the array — vadian, Dec 09 '21 at 08:34
please share your code example to understand what you are doing and where's the issue — Muhammad Nawaz, Dec 09 '21 at 08:35

For Swift Use .enumerated() with array to get index with item in for loop

let array = ["element1", "element2", "element3", "element4"]

for (index,item) in array.enumerated() {
  print(index,item)
}

for SwiftUI this link will help you

Using Range and Count

struct ContentView: View {
    @State private var array = [1, 1, 2]

    func doSomething(index: Int) {
        self.array = [1, 2, 3]
    }
    
    var body: some View {
        ForEach(0..<array.count) { i in
          Text("\(self.array[i])")
            .onTapGesture { self.doSomething(index: i) }
        }
    }
}
