An improved backport is now available as a set of .backport.presentation modifiers, in a single Backports library, with a LOT more additions. This should simply my efforts and allow me and others to contribute more backports in the near future. SwiftUI Backports

Presentation

Also available as a part of my SwiftUI+ Collection – just add it to Xcode 13+

Provides a custom presentation modifier that provides more options including full screen presentations.

Features

Presentation allows the configuration of the following properties:

• UIModalTransitionStyle
• UIModalPresentationStyle
• isModalInPresentation
• Easy API for presenting SwiftUI from UIKit

Example

Sheet replacement in SwiftUI with a custom environment value:

struct Presenting: View {
    @State private var presentSheet: Bool = false
    @State private var presentFullscreen: Bool = false

    var body: some View {
        VStack(spacing: 20) {
            Button {
                presentSheet = true
            } label: {
                Text("Present Modal")
            }
            .present(isPresented: $present) { Presented() }

            Button {
                presentFullscreen = true
            } label: {
                Text("Present Fullscreen")
            }
            .present(isPresented: $present, style: .fullscreen) { Presented() }
        }
    }
}

struct Presented: View {
    @Environment(\.presentation) private var presentation // note this is __not__ `presentationMode`
    var body: some View {
        Button {
            presentation.wrappedValue.dismiss() // but it has an identical API
        } label: {
            Text("Dismiss")
        }
    }
}

Present from UIKit with a convenient and familiar API:

controller.present(Presented())

Installation

The code is packaged as a framework. You can install manually (by copying the files in the Sources directory) or using Swift Package Manager (preferred)

To install using Swift Package Manager, add this to the dependencies section of your Package.swift file:

.package(url: "https://github.com/SwiftUI-Plus/Presentation.git", .upToNextMinor(from: "1.0.0"))

Note: The package requires iOS v13+

Other Packages

If you want easy access to this and more packages, add the following collection to your Xcode 13+ configuration:
