# clipsToBounds A Boolean value that indicates whether the view, and its subviews, confine their drawing areas to the bounds of the view. ``` var clipsToBounds: Bool { get set } ``` ## Discussion Setting this value to causes the view, and its subviews, to clip themselves to the bounds of the view. Setting it to prevents views and subviews whose frames extend beyond the visible bounds of the view from clipping themselves. A value of has no effect on [`hitTest(_:)`](/documentation/AppKit/NSView/hitTest(_:)) but does affect [`visibleRect`](/documentation/AppKit/NSView/visibleRect), as well as the area drawn inside [`draw(_:)`](/documentation/AppKit/NSView/draw(_:)). By default this value is . In macOS 13 and earlier, the default value is . Because of this change in default value, views built on macOS 13 and earlier may require layout adjustments such as the following on newer versions of macOS: - Showing or hiding UI elements by setting a parent’s frame size to zero. To hide a view hierarchy by shrinking the parent view, or positioning a child view outside a parent’s bounds, set the [`clipsToBounds`](/documentation/AppKit/NSView/clipsToBounds) property of the parent view to . Alternatively, set [`isHidden`](/documentation/AppKit/NSView/isHidden) to on the parent view instead. - Filling the `dirtyRect` of a view inside [`draw(_:)`](/documentation/AppKit/NSView/draw(_:)). It’s a common practice to set the background color on a view by calling [`setFill()`](/documentation/AppKit/NSColor/setFill()) on a background color and then calling on the `dirtyRect` parameter passed into an override of [`draw(_:)`](/documentation/AppKit/NSView/draw(_:)). Because the `dirtyRect` now extends outside your view’s bounds, call on the view’s bounds instead of the `dirtyRect`, or set the view’s [`clipsToBounds`](/documentation/AppKit/NSView/clipsToBounds) to . - Differentiating a view’s bounds from its `dirtyRect`. Use the `dirtyRect` parameter passed to [`draw(_:)`](/documentation/AppKit/NSView/draw(_:)) to determine what to draw, not where to draw it. Use the view’s [`bounds`](/documentation/AppKit/NSView/bounds) to determine the layout of what your view draws. --- Copyright © 2026 Apple Inc.
