Re-explain

some View is an opaque return type introduced in Swift 5.1. It tells the compiler that the function will return a specific type that conforms to the View protocol, but the exact type doesn't need to be known by the caller.
Benefits:

  • Type Safety: The compiler knows the exact type internally
  • Performance: Enables optimizations since the type is known at compile time
  • Flexibility: You can return different view types without exposing implementation details
  • Automatic Type Inference: The compiler figures out the return type automatically
