How does Swift's strong typing affect working with JSON data that can have mixed types?
ASwift ignores types and treats all JSON values as strings
BSwift requires explicit type checks and conversions for JSON values
CSwift automatically converts JSON types to matching Swift types
DSwift does not support JSON parsing due to strong typing
Step-by-Step Solution
Solution:

  1. Step 1: Recognize JSON mixed types

    JSON can contain strings, numbers, booleans, etc., mixed together.

  2. Step 2: Understand Swift's type safety

    Swift requires you to check and convert JSON values explicitly to correct types.

  3. Final Answer:

    Swift requires explicit type checks and conversions for JSON values -> Option B

  4. Quick Check:

    Strong typing needs explicit JSON type handling [OK]
Quick Trick: Always check and convert JSON types explicitly [OK]
Common Mistakes:
  • Assuming automatic JSON type conversion
  • Ignoring type safety when parsing JSON
  • Expecting Swift to treat all JSON as strings
