Returns the difference needed to produce this collection’s ordered elements from the given collection.
SDK
- Xcode 11.0+
Framework
- Swift Standard Library
Declaration
func difference<C>(from other: C) -> CollectionParameters
otherThe base state.
Return Value
The difference needed to produce this collection’s ordered elements from the given collection.
Discussion
This function does not infer element moves. If you need to infer moves, call the inferring method on the resulting difference.
Complexity: Worst case performance is O(n * m), where n is the count of this collection and m is other. You can expect faster execution when the collections share many common elements, or if Element conforms to Hashable.
