iOS Swift - Local Data Persistence

You wrote this code but your app crashes at runtime:

@Model
class Task {
  var title: String
  init(title: String) {
    self.title = title
  }
}

What is the likely cause of the crash?

AThe class is missing a default initializer for SwiftData.

BYou must mark the class as <code>final</code> when using @Model.

CThe property <code>title</code> must be optional.

DYou cannot use classes with @Model, only structs.

Step-by-Step Solution

Solution:

Step 1: Check SwiftData model requirements
SwiftData requires model classes to have a default initializer or all properties to have default values.
Step 2: Identify missing default initializer
The class has a custom initializer but no default one, causing runtime issues.
Final Answer:
The class is missing a default initializer for SwiftData. -> Option A
Quick Check:
SwiftData models need default initializers [OK]

Quick Trick: Ensure @Model classes have default initializers [OK]
