[Solved] Why does this code cause a compile error? for number in asyncStream { print(number) } — Ans: Missing 'await' keyword in the for loop | iOS Swift

iOS Swift - Concurrency

Why does this code cause a compile error?

for number in asyncStream {
  print(number)
}

Aprint() cannot be used inside async loops

BAsyncStream cannot be iterated with for loops

CMissing 'await' keyword in the for loop

DasyncStream must be awaited before the loop

Step-by-Step Solution

Solution:

Step 1: Identify async iteration syntax
Async sequences require 'for await' to iterate asynchronously.
Step 2: Check code for missing keyword
The code uses 'for' without 'await', causing a compile error.
Final Answer:
Missing 'await' keyword in the for loop -> Option C
Quick Check:
'for await' needed for async sequence loops [OK]

Quick Trick: Always use 'for await' with async sequences [OK]
