I’m trying to add a search filter UI like the one used in the Music app. I’ve tried to add a reusable view to the search controller collection view but there seems to be padding around it. My plan was just to add a Collection View there and try recreate the animation used. I tried scope buttons but those are a segment control, so they only hold a few options.

I removed a pod from my project and when I went to commit I got a whole list of the deleted files marked with exclamation marks saying they're "missing". I've cleaned the build folder, deleted derived data etc but these still keep coming up.

In my view controller I have a collection view and over that there is a scroll view (covering the whole main view). The collection view acts as a sort of "header" to the scroll view and has images in it. The scrollview has a clear view at the top the same size as the collection view to make the collection view visible through the scrollview - collectionViewTouchView. This is done so I can create a parallax effect when scrolling. The problem is that I can't swipe on the collection view because the scrollview is over it. Can I somehow record touch events on collectionViewTouchView and then pass it directly to the collection view?

I'm looking to get a GPU to use for Object capture. The requirements are an AMD GPU with 4GB of VRAM and ray tracing support, the rx 580 seems to be able to do ray tracing from what I've found online but looks like someone had an issue with a 580X here https://developer.apple.com/forums/thread/689891

I have an ARSCNView with nodes in AR. The UI guides you in scaling an object and the images captured are used to create a 3D model. When I try take a picture using arView.snapshot() it basically takes a screenshot a the resolution is the screen resolution and the nodes are visible. I also noticed that the AR View displays a lower quality output than the camera app. If I try get a separate camera output with AVFoundation then the arView doesn't get an output and vive versa, it only allows one view to access the camera. Is it possible to get a full resolution image without the nodes visible from the AR View (if I hide them, capture the image and display them again they do flicker) or is it possible to have 2 camera streams one to the arView and the other used to solely capture images (this one does not need to visible on screen)

In my app user accounts are handled with Firebase Auth. When creating a user how can I get the system to suggest a Unique password (that prompt that comes up on the keyboard) and also how can i get it to save these details to the keychain. My app will have a website in the future so I want the details come up when the user tries to login there. When the user logs in i used the func below to save the details to the keychain, it says the details have been saved but it doesnt seem to come up in the passwords tab in Settings. func saveCredentialsToKeychain(email: String, password: String) { let query: [String: Any] = [ kSecClass as String: kSecClassInternetPassword, kSecAttrServer as String: "myWebsite.com", kSecAttrAccount as String: email, kSecValueData as String: password.data(using: .utf8)!, kSecAttrAccessible as String: kSecAttrAccessibleWhenUnlocked ] let status = SecItemAdd(query as CFDictionary, nil) if status == errSecSuccess { print("Credentials saved to Keychain") } else { print("Error saving credentials to Keychain: \(status)") } }

I have a CollectionView in my SwiftUI App. The collectionView is wrapped in a UIViewRepresentable. If I tap on a collectionView cell normally the function isn't called but if I hold the cell down the console prints <0x107507790> Gesture: System gesture gate timed out. and when I let go of the cell after that's printed then didSelectItem is called. Here is my CollectionView Class: class SessionsCollectionView: UIView, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout { lazy var collectionView: UICollectionView = { let layout = UICollectionViewFlowLayout() layout.minimumInteritemSpacing = 0 layout.minimumLineSpacing = 30 let collectionView = UICollectionView(frame: CGRect.zero, collectionViewLayout: layout) collectionView.translatesAutoresizingMaskIntoConstraints = false collectionView.dataSource = self collectionView.delegate = self collectionView.clipsToBounds = false collectionView.delaysContentTouches = false collectionView.register(SessionCell.self, forCellWithReuseIdentifier: "cell") collectionView.register(SessionsHeader.self, forSupplementaryViewOfKind: UICollectionView.elementKindSectionHeader, withReuseIdentifier: "header") return collectionView }() override init(frame: CGRect) { super.init(frame: frame) self.backgroundColor = .clear setupCollectionView() } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } private func setupCollectionView() { addSubview(collectionView) collectionView.backgroundColor = .clear collectionView.alwaysBounceVertical = true collectionView.alwaysBounceHorizontal = false collectionView.delaysContentTouches = false collectionView.contentInset = .init(top: 20, left: 0, bottom: 20, right: 0) collectionView.showsVerticalScrollIndicator = false NSLayoutConstraint.activate([ collectionView.topAnchor.constraint(equalTo: topAnchor), collectionView.leadingAnchor.constraint(equalTo: leadingAnchor), collectionView.trailingAnchor.constraint(equalTo: trailingAnchor), collectionView.bottomAnchor.constraint(equalTo: bottomAnchor) ]) } // MARK: Header func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -> UICollectionReusableView { if kind == UICollectionView.elementKindSectionHeader { let sectionHeader = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "header", for: indexPath) as! Header return sectionHeader } } func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, referenceSizeForHeaderInSection section: Int) -> CGSize { let width: CGFloat = collectionView.frame.width let height: CGFloat = 33 + 20 return CGSize(width: width, height: height) } // MARK: - UICollectionViewDataSource func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return 10 } func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! SessionCell return cell } // MARK: - UICollectionViewDelegateFlowLayout func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { let width = collectionView.bounds.width let height = 150 return CGSize(width: collectionView.bounds.width, height: height) } func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { print(indexPath.row) } } struct SessionsCollectionViewWrapper: UIViewRepresentable { var sessionViewNavigation: SessionViewNavigation func makeUIView(context: Context) -> SessionsCollectionView { let sessionsCollectionView = SessionsCollectionView() return sessionsCollectionView } func updateUIView(_ uiView: SessionsCollectionView, context: Context) { // Update any properties or handle updates if needed } }
