init(base:bounds:)

Creates a view into the given collection that allows access to elements within the specified range.

Declaration

init(base: Base, bounds: Range<Base.Index>)

Parameters

  • base:

    The collection to create a view into.

  • bounds:

    The range of indices to allow access to in the new slice.

Discussion

It is unusual to need to call this method directly. Instead, create a slice of a collection by using the collection’s range-based subscript or by using methods that return a subsequence.

let singleDigits = 0...9
let subSequence = singleDigits.dropFirst(5)
print(Array(subSequence))
// Prints "[5, 6, 7, 8, 9]"

In this example, the expression singleDigits.dropFirst(5)) is equivalent to calling this initializer with singleDigits and a range covering the last five items of singleDigits.indices.
