# PhotosPicker issue on iOS 18

This is a minimum demo that can replicate the PhotosPicker issue on iOS 18:

1. Run the app on iOS 18.

2. Click the "Pick photo" button, which will invoke the PhotosPicker.

3. Navigate to the "Collection" tab, and the picker will show a "failure" UI.

The code is rather simple:

```swift

struct ContentView: View {

    @State private var selection: PhotosPickerItem? = nil

    

    var body: some View {

        VStack {

            Image(systemName: "globe")

                .imageScale(.large)

                .foregroundStyle(.tint)

            Text("Hello, world!")

            

            PhotosPicker("Pick photo", selection: $selection)

        }

        .padding()

    }

}

```

## Workround

We can avoid this issue by disabling the Collections feature in PhotosPicker. However this API isn't exposed in SwiftUI. You have bridge your SwiftUI view to use `PHPickerViewController`, which is the underlying part in `PhotosPicker`.

```swift

private func createNewInstance(sizeLimit: Int) -> PHPickerViewController {    

    var configuration = PHPickerConfiguration(photoLibrary: .shared())

    configuration.filter = PHPickerFilter.any(of: [.images])

    configuration.preferredAssetRepresentationMode = .current

    configuration.selection = .ordered

    configuration.selectionLimit = sizeLimit

    

    // Workaround to prevent users navigate to the Collections tab, which will crash.

    // https://developer.apple.com/documentation/uikit/view_controllers/collaborating_and_sharing_copies_of_your_data

    if #available(iOS 18.0, *) {

        configuration.disabledCapabilities = [.collectionNavigation]

    }

    

    return PHPickerViewController(configuration: configuration)

}

```
