Instance MethodSwift
shuffled(using:)
Returns the elements of the sequence, shuffled using the given generator as a source for randomness.
func shuffled<T>(using generator: inout T) -> [Self.Element] where T : RandomNumberGenerator
Parameters
- generator
The random number generator to use when shuffling the sequence.
Returns
An array of this sequence’s elements in a shuffled order.
Overview
You use this method to randomize the elements of a sequence when you are using a custom random number generator. For example, you can shuffle the numbers between 0
and 9
by calling the shuffled(using:)
method on that range:
let numbers = 0...9
let shuffledNumbers = numbers.shuffled(using: &myGenerator)
// shuffledNumbers == [8, 9, 4, 3, 2, 6, 7, 0, 5, 1]
