copy(with:)

Returns a new instance that’s a copy of the receiver.

Declaration

func copy(with zone: NSZone? = nil) -> Any

Parameters

  • zone:

    This parameter is ignored. Memory zones are no longer used by Objective-C.

Discussion

The returned object is implicitly retained by the sender, who is responsible for releasing it. The copy returned is immutable if the consideration “immutable vs. mutable” applies to the receiving object; otherwise the exact nature of the copy is determined by the class.
