iOS Swift - Lists and Data Display

Which of the following is the correct syntax to create a List with ForEach over an array items of strings in SwiftUI?

AList { ForEach(items, id: \.index) { item in Text(item) } }

BList { ForEach(items) { item in Text(item) } }

CList { ForEach(items, id: \.id) { item in Text(item) } }

DList { ForEach(items, id: \.self) { item in Text(item) } }

Step-by-Step Solution

Solution:

Step 1: Check ForEach syntax
When iterating over a simple array of strings, use id: \.self to identify each item uniquely.
Step 2: Validate options
List { ForEach(items, id: \.self) { item in Text(item) } } uses correct syntax with id: \.self. List { ForEach(items) { item in Text(item) } } misses the id parameter, causing errors. Options C and D use invalid keys for strings.
Final Answer:
List { ForEach(items, id: \.self) { item in Text(item) } } -> Option D
Quick Check:
ForEach with id: \.self for string arrays [OK]

Quick Trick: Use id: \.self for arrays of simple values [OK]
