Pick all that apply

• 1Choice 1.

  It's a technique that intercepts existing method calls by changing the selector-to-implementation (IMP) mapping in the Objective-C runtime, and it also applies to Swift methods marked @objc dynamic

• 2Choice 2.

  Ordinary methods on a pure Swift class can be swizzled at any time, regardless of static dispatch

• 3Choice 3.

  It's used to slip cross-cutting concerns into every UIViewController's viewDidAppear, like automatic screen-view logging, but when several libraries swizzle the same method you get ordering and duplication problems

• 4Choice 4.

  To call the original implementation from inside the swizzled one, you call the new selector, not the original selector (since they've been exchanged)

• 5Choice 5.

  On iOS 18 with Swift 6, the runtime blocks swizzling, so it no longer works
