# GeometryProxy3D A proxy for access to the size and coordinate space of the container view. ``` struct GeometryProxy3D ``` ## Overview You can use a proxy for anchor resolution. ## Topics ### Accessing geometry characteristics [`func frame(in: some CoordinateSpaceProtocol) -> Rect3D`](/documentation/SwiftUI/GeometryProxy3D/frame(in:)) The container view’s bounds rectangle converted to a defined coordinate space. [`var size: Size3D`](/documentation/SwiftUI/GeometryProxy3D/size) The size of the container view. [`var safeAreaInsets: EdgeInsets3D`](/documentation/SwiftUI/GeometryProxy3D/safeAreaInsets) The safe area inset of the container view. [`subscript(Anchor) -> T`](/documentation/SwiftUI/GeometryProxy3D/subscript(_:)) Resolves the value of an anchor to the container view. [`func transform(in: some CoordinateSpaceProtocol) -> AffineTransform3D?`](/documentation/SwiftUI/GeometryProxy3D/transform(in:)) The container view’s 3D transform converted to a defined coordinate space. ### Instance Methods [`func coordinateSpace3D(for: any CoordinateSpaceProtocol) -> GeometryProxyCoordinateSpace3D`](/documentation/SwiftUI/GeometryProxy3D/coordinateSpace3D(for:)) Returns a value that can be used for `CoordinateSpace3D` based coordinate conversions. --- Copyright © 2026 Apple Inc.
