# overlaps(_:) Returns a Boolean value indicating whether this range and the given closed range contain an element in common. ``` func overlaps(_ other: ClosedRange) -> Bool ``` ## Parameters `other` A closed 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 half-open range does not include its upper bound, the ranges in the following example do not overlap: ``` let y = 20...30 print(x.overlaps(y)) // Prints "false" ``` --- Copyright © 2026 Apple Inc.
