iOS Swift - Lists and Data Display

Which of these is a correct way to use ForEach inside a SwiftUI List with an array numbers = [1, 2, 3]?

AList { ForEach(numbers, id: \.self) { number in Text(\"\(number)\") } }

BList { ForEach(numbers, id: \x\) { number in Text(\"\(number)\") } }

CList { ForEach(numbers) { Text(\"\(number)\") } }

DList { ForEach(numbers, id: \.count) { number in Text(\"\(number)\") } }

Step-by-Step Solution

Solution:

Step 1: Identify correct ForEach syntax
ForEach requires an id parameter for unique identification, usually \id: \.self\ for simple arrays.
Step 2: Check each option
List { ForEach(numbers, id: \.self) { number in Text(\"\(number)\") } } uses correct syntax with \id: \.self\ and closure with number parameter.
Final Answer:
List { ForEach(numbers, id: \.self) { number in Text(\"\(number)\") } } -> Option A
Quick Check:
ForEach syntax = id: \.self [OK]

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