EXIF metadata is stripped when creating an asset via addResource(with:.photo, data:) on iOS 26.6
Starting with iOS 26.6, saving an image to the photo library via PHAssetCreationRequest.addResource(with: .photo, data:, options:) appears to re-encode the image, dropping all EXIF metadata. The same code preserved metadata through iOS 26.5. let creationRequest = PHAssetCreationRequest.forAsset() creationRequest.addResource(with: .photo, data: image, options: nil) I would like to know whether this change is intentional, and whether the file-based overload is the supported way to preserve an image's original metadata. What we verified The bytes we hand to PhotoKit still contain the metadata. Setting contentType explicitly does not help. We resolved the type from the data and confirmed at runtime that it was non-nil (public.jpeg): let options = PHAssetResourceCreationOptions() if #available(iOS 26.0, *) { options.contentType = contentType // verified: UTType.jpeg, not nil } let request = PHAssetCreationRequest.forAsset() request.addResource(with: .photo, data: imageData, options: options) The resulting asset still has no EXIF. Writing the identical bytes to a temporary file and using the file-based overload preserves everything: try imageData.write(to: temporaryFileURL, options: .atomic) let options = PHAssetResourceCreationOptions() options.shouldMoveFile = true let request = PHAssetCreationRequest.forAsset() request.addResource(with: .photo, fileURL: temporaryFileURL, options: options) Capture date, camera information and location are all intact. We access the library with PHAccessLevel.addOnly.

iOS app running in compatibility mode on Apple Vision Pro does not apply hoverEffect to SwiftUI View
We tested our iOS app on visionOS and found that the hover effect works on most of UIKit views, but it does not work on most of SwiftUI views. SwiftUI views are used within UIHostingController. I created a new project (Storyboard based iOS app) and displayed the following SwiftUI view in UIHostingController and found that the buttons in the List were highlighted, but not the standalone buttons. struct SwiftUIView: View { var body: some View { List { // This button has the hover effect. Button { print("Hello") } label: { Text("Hello") } } // This button does't have the hover effect. Button { print("Hello") } label: { Text("Hello") } .hoverEffect() } } Is there a way to highlight any SwiftUI view?
