Swift - Optionals

Why does Swift require explicit unwrapping of optionals instead of automatically unwrapping them?

ATo make code shorter and easier to write

BTo prevent unexpected nil values causing runtime crashes

CBecause Swift does not support nil values

DTo allow optionals to change type dynamically

Step-by-Step Solution

Solution:

Step 1: Understand Swift's safety design
Swift forces explicit unwrapping to avoid silent crashes from nil values.
Step 2: Reason about automatic unwrapping
Automatic unwrapping could hide bugs and cause unexpected crashes at runtime.
Final Answer:
To prevent unexpected nil values causing runtime crashes -> Option B
Quick Check:
Explicit unwrapping prevents crashes = A [OK]

Quick Trick: Explicit unwrapping avoids hidden nil crashes [OK]
