“build disappears”

Good evening, I am a beginner in SwiftUI (and in code in general). I am currently trying to make an application for a university project. I would like to organize the layout of my different tabs. I'm trying to manage by taking different pieces of code from the internet to form what I want to achieve. Currently I'm stuck for 8 hours on something that seems simple: A code I copied allowed me to put a presentation name that disappears when you scroll up the page content. I didn't like the TabBar, so I replaced it with a template that has a more fluid animation. I am in the following situation: I would like to form a Home tab with 2 categories: News and Challenges. For this, I have four Swift files: i. MixView ii. MixTabBar iii. NewsView iv. ChallengesView The problem comes from the fact that initially on the viewed youtube video, the data of the News page was present on the home page. Scrolling this data made the header disappear. As I also have the Challenges, I have to (I think) find a way to

I'm programatically trying to add a label to the collection view when the collection view is empty so let the user know that the collection view is empty. I created a function to do this. However, whenever the collection view isn't empty anymore, I can't get the label to disappear, does anyone know how I can change this. Here is my code:func EmptyCollectionView() { if communities.count == 0 { let messageLabel = UILabel(frame: CGRect(x: 20.0, y: 0, width: self.collectionViews!.bounds.size.width - 40.0, height: (self.collectionViews?.bounds.size.height)!)) messageLabel.text = You haven't created anything yet! messageLabel.font = messageLabel.font.withSize(20) messageLabel.font = UIFont.boldSystemFont(ofSize: messageLabel.font.pointSize) messageLabel.textColor = colorCircleBlue messageLabel.numberOfLines = 0 messageLabel.textAlignment = NSTextAlignment.center messageLabel.sizeToFit() self.collectionViews?.backgroundView = messageLabel } else { addPhoto() } }

Any possible solution?

I have a simple UITextView with a custom NSLayoutManager in my app. The UITextView have a tap gesture and when you tap on UITextView it animates off the screen. My problem is that when you tap on the UITextView the entire text disappears. After debugging for a while I think it has something to do with NSTextContainer which I pass to the UITextView because If I don't pass it everything works fine. I thought it had to do something with my custom NSLayoutManager but then I tested it with a default NSLayoutManger and it is still giving the same issue. Can you please tell me what is going wrong? I have attached a sample code for your reference. I have slowed down the animation so can see what is wrong. class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() setUpTextView() } private func setUpTextView() { let rect = CGRect(origin: CGPoint(x: view.frame.origin.x, y: view.frame.origin.y + 50 ), size: CGSize(width: view.frame.width, height: view.frame.height - 50 ) ) let te

Hello, I used AVPlayer in my project to play network movie. Most movie could play normally, but I found the sound will disappear sometimes if I play specified 4K video network stream. The video will continue playing but audio stops after video is played for a while. If I pause player and then resume, the sound will be back but disappeared again after several seconds Check AVPlayerItem status: isPlaybackLikelyToKeepUp` == true isPlaybackBufferEmpty` = false player.volume > 0 According the value above, it seems not cause by empty playback buffer or volume issue. I am so confused for this situation.

If you have a form like the below, to show some fields just when a specific option of a Picker is selected (so it appears/disappears based on the picker selected option) if you are running an Ipad and you are inside (keyboard opened) of any of the fields that will disappear if you select the other Picker element, once doing it the app crashes:Picker(selection: $createAccount, label: Text()) { Text(New Account) .tag(0) Text(Existing Account) .tag(1) } .pickerStyle(SegmentedPickerStyle()) Form { Section(header: Text(Personal information)) { if (self.createAccount == 0) { TextField(Name, text: self.$name) } } }This happens if you play with .disabled too.Does anyone have a workaround? Perhaps this is a known bug?Crash traceException Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Termination Signal: Illegal instruction: 4 Termination Reason: Namespace SIGNAL, Code 0x4 Terminating Process: exc handler [17379] Application

I have lost about 30 notes after a recent iOS updates. Everything neatly sorted into headings - minus my notes. Does anyone have any ideas please how I can find my missing notes??

Installed iOS 10 beta on Sprint iPhone 5s. Noticed laggy performance. As well as fuzzy/blurry icons when exiting app or pulling up a folder and closing it out. Went to reduce motion and reduce transparency. When going back to the home screen, the folder that I had opened to get to my settings is no longer visible, but the spot is still being recognized. Tried locking phone, enabling said features again. Only way to restore visibility of folder is powering the phone down and turning it back on.
