Why might you choose a tuple over a struct in Swift for grouping values?
ATuples allow stored properties with default values
BTuples are lightweight and useful for temporary groupings without defining a new type
CTuples can be extended with protocols
DTuples support methods and inheritance like classes
Step-by-Step Solution
Solution:

  1. Step 1: Compare tuples and structs

    Tuples are simple, lightweight groupings without needing a new type definition, ideal for quick grouping.

  2. Step 2: Analyze options

    Tuples are lightweight and useful for temporary groupings without defining a new type correctly states tuples are lightweight and temporary. Options A, B, and C describe struct/class features not available to tuples.

  3. Final Answer:

    Tuples are lightweight and useful for temporary groupings without defining a new type -> Option B

  4. Quick Check:

    Tuples = lightweight temporary groups [OK]
Quick Trick: Use tuples for quick groups, structs for complex types [OK]
Common Mistakes:
  • Thinking tuples have methods or inheritance
  • Assuming tuples can conform to protocols
  • Confusing tuples with structs
