Shuffles the collection in place, using the given generator as a source for randomness.
SDK
- Xcode 10.0+
Framework
- Swift Standard Library
Declaration
mutating func shuffle<T>(using generator: inout T) where T : RandomAvailable when Self conforms to Random
Parameters
generatorThe random number generator to use when shuffling the collection.
Discussion
You use this method to randomize the elements of a collection when you are using a custom random number generator. For example, you can use the shuffle(using:) method to randomly reorder the elements of an array.
var names = ["Alejandro", "Camila", "Diego", "Luciana", "Luis", "Sofía"]
names.shuffle(using: &myGenerator)
// names == ["Sofía", "Alejandro", "Camila", "Luis", "Diego", "Luciana"]
Complexity: O(n), where n is the length of the collection.
