overlaps(_:)

Returns a Boolean value indicating whether this range and the given range contain an element in common.

Declaration

func overlaps(_ other: Range<Bound>) -> Bool

Parameters

  • other:

    A range to check for elements in common.

Return Value

true if this range and other have at least one element in common; otherwise, false.

Discussion

This example shows two overlapping ranges:

let x: Range = 0...20
print(x.overlaps(10..<1000))
// Prints "true"

Because a closed range includes its upper bound, the ranges in the following example overlap:

let y = 20..<30
print(x.overlaps(y))
// Prints "true"
