hard📝 Conceptual Q10 of 15
Swift - Loops
Why does Swift enforce safety on loops modifying collections instead of allowing runtime errors?
ATo catch errors early and improve code reliability
BTo make loops run slower intentionally
CTo force developers to write longer code
DTo prevent any kind of collection usage
Step-by-Step Solution
Solution:

  1. Step 1: Understand Swift's design philosophy

    Swift aims to catch errors at compile time to avoid runtime surprises.

  2. Step 2: Recognize benefits of early error detection

    This improves code safety and reliability by preventing crashes during execution.

  3. Final Answer:

    To catch errors early and improve code reliability -> Option A

  4. Quick Check:

    Swift safety = Early error detection [OK]
Quick Trick: Swift catches errors early for safer code [OK]
Common Mistakes:
  • Thinking safety slows down code
  • Believing safety forces longer code
  • Assuming safety restricts collection use
