Photo picker using fullscreencover in SwiftUI

View.swift

import SwiftUI
import PhotosUI

struct ContentView: View {
    @State var showPhotoPicker = false
    @State var selectedImage: UIImage?

    var body: some View {
        VStack {
            if let image = selectedImage {
                Image(uiImage: image)
                    .resizable()
                    .aspectRatio(contentMode: .fit)
            } else {
                Text("No Image Selected")
            }

            Button("Select Photo") {
                self.showPhotoPicker = true
            }
            .fullScreenCover(isPresented: $showPhotoPicker) {
                PhotoPicker(selectedImage: self.$selectedImage)
            }
        }
    }
}

struct PhotoPicker: UIViewControllerRepresentable {
    @Environment(\.presentationMode) var presentationMode
    @Binding var selectedImage: UIImage?

    func makeUIViewController(context: Context) -> PHPickerViewController {
        var configuration = PHPickerConfiguration()
        configuration.filter = .images
        configuration.selectionLimit = 1
        let picker = PHPickerViewController(configuration: configuration)
        picker.delegate = context.coordinator
        return picker
    }

    func updateUIViewController(_ uiViewController: PHPickerViewController, context: Context) {}

    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }

    class Coordinator: PHPickerViewControllerDelegate {
        let parent: PhotoPicker

        init(_ parent: PhotoPicker) {
            self.parent = parent
        }

        func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
            if let image = results.first?.itemProvider.loadObject(ofClass: UIImage.self) as? UIImage {
                self.parent.selectedImage = image
                self.parent.presentationMode.wrappedValue.dismiss()
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

Re original question: "Is it possible in SwiftUI to display the PhotoPicker using fullScreenCover? #SwiftUI"

Awesome, thank you very much for the example. I had trouble with func picker(_:,:) in Xcode 14.3 Beta 3. I corrected using the following version:

func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
    picker.dismiss(animated: true)
    
    let imageItems = results
        .map { $0.itemProvider }
        .filter { $0.canLoadObject(ofClass: UIImage.self) } // filter for possible UIImages
    
    let dispatchGroup = DispatchGroup()
    var images = [UIImage]()
    
    for imageItem in imageItems {
        dispatchGroup.enter()
        imageItem.loadObject(ofClass: UIImage.self) { image, _ in
            if let image = image as? UIImage {
                images.append(image)
            }
            dispatchGroup.leave()
        }
    }
    
    dispatchGroup.notify(queue: .main) {
        print(images)
    }
}

The rest works great. Cheers!
