Using a UISheetPresentationController in SwiftUI
This article explores how you can create a layered and customized sheet experience in SwiftUI.
During WWDC 2021 Apple has announced a new way to create a layered and customized sheet experience in UIKit. This is possible using a new UIPresentationController subclass called UISheetPresentationController.
If you want to know more about it check out the following session from WWDC 2021 which talks about how we can build a non-modal experience in our app to allow interaction with content both in a sheet and behind the sheet at the same time.
UIKit now supports medium/large detents, which allows you to create a vertically resizable sheet that only covers half the screen. This is why it is often referred to as half-modal or full-modal. if you want to know more about detens have a look at Apple’s documentation.
SwiftUI currently provides only one way to achieve a modal experience. sheet(isPresented:onDismiss:content:) is a view modifier that presents a sheet with a large detent only when a given condition is true. What we would like instead is to use the UIKit exclusive medium detent in our SwiftUI apps.
