Swift - Loops

Why are Swift loops considered safe by default?

AThey allow infinite loops without any checks.

BThey check conditions before each iteration to avoid errors.

CThey require manual index management to prevent errors.

DThey do not support looping over collections.

Step-by-Step Solution

Solution:

Step 1: Understand Swift loop behavior
Swift loops automatically check the loop condition before each iteration to ensure safety.
Step 2: Compare options with loop safety
Only They check conditions before each iteration to avoid errors. describes this safety feature correctly; others describe unsafe or incorrect behaviors.
Final Answer:
They check conditions before each iteration to avoid errors. -> Option B
Quick Check:
Loop safety = condition checks before iteration [OK]

Quick Trick: Remember: Swift loops always check conditions first [OK]
