What benefit does returning a tuple from a Swift function provide compared to returning a single value?
AIt allows returning multiple related values without creating a custom type
BIt enforces type safety by restricting return types to one value only
CIt automatically converts the return values to an array
DIt improves performance by avoiding memory allocation
Step-by-Step Solution
Solution:

  1. Step 1: Understand tuple returns

    Tuples allow grouping multiple values into one compound value.

  2. Step 2: Compare with single return values

    Returning a tuple lets a function return multiple related values without defining a new struct or class.

  3. Final Answer:

    It allows returning multiple related values without creating a custom type -> Option A

  4. Quick Check:

    Tuples group multiple values [OK]
Quick Trick: Tuples return multiple values together [OK]
Common Mistakes:
  • Thinking tuples convert to arrays automatically
  • Believing tuples restrict to one return value
  • Assuming tuples improve performance inherently
