iOS Swift - Local Data Persistence

What is wrong with this SwiftData container setup?

let container = ModelContainer(for: [Person.self, Task.self])
let context = container.mainContext
context.insert(Person(name: "Alice"))

APerson must be a struct, not a class.

BYou cannot insert objects directly into modelContext.

CModelContainer cannot handle multiple model types.

DModelContainer initializer expects a variadic list, not an array.

Step-by-Step Solution

Solution:

Step 1: Check ModelContainer initializer syntax
ModelContainer expects a variadic list of model types, not an array.
Step 2: Analyze the code
Passing an array causes a type mismatch error; correct usage is ModelContainer(for: Person.self, Task.self).
Final Answer:
ModelContainer initializer expects a variadic list, not an array. -> Option D
Quick Check:
ModelContainer(for:) needs variadic types, not array [OK]

Quick Trick: Pass model types as separate arguments, not array [OK]
