Why will this Stepper code cause a runtime issue?
@State private var number = 10
Stepper("Number", value: $number, in: 0...5)
AThe initial value 10 is outside the specified range 0...5.
BThe Stepper label must be a closure, not a string.
CThe @State variable cannot be private.
DThe range must be specified as 1...10, not 0...5.
Step-by-Step Solution
Solution:

  1. Step 1: Check initial value

    The variable number is initialized to 10, which is outside the Stepper's allowed range of 0 to 5.

  2. Step 2: Effect of mismatch

    This causes the Stepper to behave unexpectedly or crash because the initial value is invalid for the range.

  3. Step 3: Label and privacy

    Using a string label and private @State is valid and not an issue.

  4. Final Answer:

    Initial value outside range -> Option A

  5. Quick Check:

    Initial value must be within range [OK]
Quick Trick: Initial value must fit Stepper range [OK]
Common Mistakes:
  • Setting initial value outside range
  • Misunderstanding label requirements
  • Assuming privacy affects Stepper
