# intersection(_:eoFill:) Returns a new shape with filled regions common to both shapes. ``` @export(implementation) nonisolated func intersection(_ other: T, eoFill: Bool = false) -> some Shape where T : Shape ``` ## Parameters `other` The shape to intersect. `eoFill` Whether to use the even-odd rule for determining which areas to treat as the interior of the shapes (if true), or the non-zero rule (if false). ## Return Value A new shape. ## Discussion The filled region of the resulting shape is the overlapping area of the filled region of both shapes. This can be used to clip the fill of a shape to a mask. Any unclosed subpaths in either shape are assumed to be closed. The result of filling this shape using either even-odd or non-zero fill rules is identical. --- Copyright © 2026 Apple Inc.
