I'm trying to add a delete action in a context menu, however it just gets displayed as the default black color. The Photos app uses a red color for its delete action as well. I've seen in some spaces online that this is not a functionality currently provided of contextMenu, however I have also seen it used in third party apps in the wild from developers such as Steve Troughton-Smith in his Broadcast app (It's not letting me link to his tweet, however he has a video showing a red item in a context menu). Does anyone know how to accomplish this?
Also, looking on Apple's documentation - https://developer.apple.com/documentation/swiftui/contextmenu for contextMenu it says that they have been deprecated for everything except for macOS. I find it strange that they deprecated it just one year after introducing it. Was this replaced by another component that I should be using?
var body: some View {
				ScrollView {
						LazyVGrid(columns: columns, spacing: 20) {
								ForEach(photos) { photo in
										Image(uiImage: UIImage(data: photo.imageData!)!)
												.resizable()
												.aspectRatio(1, contentMode: .fill)
												.contextMenu(menuItems: {
														Button(action: {
																deletePhoto(selectedPhoto: photo)
														}) {
																Label("Remove", systemImage: "trash")
														}
												})
								}
						}
						.padding()
						.navigationBarTitle(Text("Albums"))
						.navigationBarItems(trailing:
								Button(action: {
										self.showingImagePicker = true
								}) {
										Image(systemName: "plus.circle.fill")
								}
						)
						.sheet(isPresented: $showingImagePicker, onDismiss: loadImage) {
								ImagePicker(image: self.$inputImage)
						}
				}
		}

I currently have an app that allows users to import photos, the photos are then stored in CoreData as Binary Data and then synced with iCloud. When a user wants to view the photo, I display the photo to them with Image(uiImage: UIImage(data: savedImageData)).
I would like to allow users to upload live photos to the application as well, and have them saved into CoreData. I have tried searching online but haven't found a concrete process to do this. So how does one save Live Photos into CoreData?
P.S. I am saving the photos from a UIImagePickerController wrapped as UIViewControllerRepresentable to input my images currently, if something else is required to get the Live Photo component as well I am open to suggestions.
I'm trying to add CoreData to my application. This application is going to be a photo application, and give the user the ability to store photos in albums. I have two Entities in CoreData currently, Photo and Album.
The Album entity has four attributes. albumCoverImageData: Binary Data, id: UUID, name: String, passwordProtected: Boolean. In addition to these attributes, it has a relationship photos destination Photo Inverse Album.
The Photo Entity has two attributes, id: UUID and imageData: BinaryData
When trying to add a new album to the database, upon trying to save the context, the application crashes with the following error.

I have a view inside of a navigation bar that I am using as a photo preview. I'd like to mimic the Photo's app behavior, and have the image extend past the navigation bar, with the contents blurred by the navigation bar in the background. If you'd like to see an example of what I'm looking to replicate, open the Photos app and select a photo, the navigation bar covers the content that extends beyond it.
However, when I extend the View to disregard the safe areas, the navigation bar is fully transparent, and the photo is not blurred at all.
I've noticed on the parent view (LazyVGrid in a ScrollView) when scrolling the view under the navigation bar, the navigation bar has my desired effect.
Is there any way to force this behavior when the view in not in a ScrollView?
Here is my code for the photo preview view.
import SwiftUI
struct PhotoDetailView: View {
		var photo: Photo
		@State var isNavbarHidden: Bool = false
		
		var body: some View {
				ZStack {
						Rectangle()
								.frame(minWidth: /*@START_MENU_TOKEN@*/0/*@END_MENU_TOKEN@*/,maxWidth: /*@START_MENU_TOKEN@*/.infinity/*@END_MENU_TOKEN@*/, minHeight: /*@START_MENU_TOKEN@*/0/*@END_MENU_TOKEN@*/,maxHeight: /*@START_MENU_TOKEN@*/.infinity/*@END_MENU_TOKEN@*/, alignment: /*@START_MENU_TOKEN@*/.center/*@END_MENU_TOKEN@*/)
								.edgesIgnoringSafeArea(.all)
								.foregroundColor(isNavbarHidden ? .black : Color(UIColor.systemBackground))
						Image(data: photo.imageData, placeholder: "No Image")
								.resizable()
								.aspectRatio(contentMode: .fit)
				}
				.edgesIgnoringSafeArea(.all)
//				.navigationBarHidden(isNavbarHidden)
				.navigationBarTitle("Test Title", displayMode: .inline)
				.onTapGesture(count: /*@START_MENU_TOKEN@*/1/*@END_MENU_TOKEN@*/, perform: {
						withAnimation {
								isNavbarHidden.toggle()
						}
				})
		}
}
