ForEach and with an index using SwiftUI

ForEachEnumerated.swift

// 01 Example with struct
// Use ForEach to provide views based on a `RandomAccessCollection` of some data type. 
// see documentation: https://developer.apple.com/documentation/swiftui/foreach

// I want the index you can do the following...
// You use `results.enumerated().map({$0}` which takes your results and returns it into an array 
// I have seen examples where you could do it like `Array(results.enumerated())`

// NOTE:
// The collection’s elements must conform to Identifiable or you need to provide an id parameter to the ForEach initializer.
// In this example I'm using a struct.

struct Foo: Indentifiable {
   var id: UUID = UUID()
   var name: String
}

let results = [Foo(name: "Example 1"), Foo(name: "Example 2")]

ForEach(results.enumerated().map({$0}), id:\.0) { index, item in
  // ... you can pass in the index or item    
}


// Example with Strings
ForEach(["baseball", "basketball", "hockey"].enumerated().map({$0}), id:\.0) { index, item in
            Text("\(item)")
 }
