## Topics

### Creating a system detent

[`large()`](/documentation/UIKit/UISheetPresentationController/Detent/large())

Creates a system detent for a sheet at full height.

[`medium()`](/documentation/UIKit/UISheetPresentationController/Detent/medium())

Creates a system detent for a sheet that’s approximately half the height of the screen, and is inactive in compact height.

### Creating a custom detent

[`custom(identifier:resolver:)`](/documentation/UIKit/UISheetPresentationController/Detent/custom(identifier:resolver:))

Creates a custom detent for a sheet by computing its value according to the properties of the provided context.

[`resolvedValue(in:)`](/documentation/UIKit/UISheetPresentationController/Detent/resolvedValue(in:))

Resolves a detent to its value.

[`customDetentWithIdentifier:resolver:`](/documentation/UIKit/UISheetPresentationControllerDetent/customDetentWithIdentifier:resolver:)

Creates a custom detent for a sheet by computing its value according to the properties of the provided context.

[`resolvedValueInContext:`](/documentation/UIKit/UISheetPresentationControllerDetent/resolvedValueInContext:)

Resolves a detent to its value.

[`UISheetPresentationControllerDetentResolutionContext`](/documentation/UIKit/UISheetPresentationControllerDetentResolutionContext)

A context for resolving custom detent values.

[`UISheetPresentationControllerDetentInactive`](/documentation/UIKit/UISheetPresentationControllerDetentInactive)

A value that represents an inactive detent.

### Identifying a detent

[`identifier`](/documentation/UIKit/UISheetPresentationController/Detent/identifier-swift.property)

The identifier of the detent.

[`UISheetPresentationController.Detent.Identifier`](/documentation/UIKit/UISheetPresentationController/Detent/Identifier-swift.struct)

Constants that identify system detent sizes.
