Generic Instance Method

shuffled(using:)

Returns the elements of the sequence, shuffled using the given generator as a source for randomness.

Parameters

`generator`

The random number generator to use when shuffling the sequence.

Return Value

An array of this sequence’s elements in a shuffled order.

Discussion

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:

Complexity: O(n), where n is the length of the sequence.

Reordering an Array's Elements

`func sort()`

Sorts the collection in place.

`func sort(by: (Element, Element) -> Bool)`

Sorts the collection in place, using the given predicate as the comparison between elements.

`func sorted() -> [Element]`

Returns the elements of the sequence, sorted.

`func sorted(by: (Element, Element) -> Bool) -> [Element]`

Returns the elements of the sequence, sorted using the given predicate as the comparison between elements.

`func reverse()`

Reverses the elements of the collection in place.

`func reversed() -> ReversedCollection<Array<Element>>`

Returns a view presenting the elements of the collection in reverse order.

`func shuffle()`

Shuffles the collection in place.

`func shuffle<T>(using: inout T)`

Shuffles the collection in place, using the given generator as a source for randomness.

`func shuffled() -> [Element]`

Returns the elements of the sequence, shuffled.

`func partition(by: (Element) -> Bool) -> Int`

Reorders the elements of the collection such that all the elements that match the given predicate are after all the elements that don’t match.

`func swapAt(Int, Int)`

Exchanges the values at the specified indices of the collection.
