build disappears

Thursday I was running a iPad Retina iOS 10.2 on my Machine. When I got into the office Friday and started my Machine up the Simulator was no longer in xCode. I attempted to add the simulator but when I went to Create a new Simulator and selected iPad Retina as the device. The OS Version drop down menu did not have the iOS 10.2 in the list.I've done a lot of things to troubleshoot this down to unistalling xCode completely removing any files on the machine, even in ~Library/ and reinstalled it completely.I'm currently running v8.3.3 of xCode and by default has iOS 10.3.1 installed. So when I went to create a new simulator I downloaded the iOS 10.2 Simulator from the components tab but there still is no version I can select in the drop down. I also downloaded iOS 9.2 to check and the drop down menu now has 9.2 iOS but does no have 10.2.I'm sorta running dry on how to fix this so I've come to this thread seeking help on how to resolve this.Thanks in advanced.-edit-So I've been messing with this more to find out

Yesterday, my Xcode IDE work fine, but today there is an error with it.

Trying to get a sticky cell that will orthogonally scroll with the section, but only partially, leaving the trailing end exposed until scrolled backwards. Demo Code: https://developer.apple.com/documentation/uikit/views_and_controls/collection_views/implementing_modern_collection_views (Download the project) Open: Modern Collection Views > Compositional Layout > Advanced layouts View Controllers > OrthogonalScrollBehaviorViewController.swift Replace func createLayout() -> UICollectionViewLayout { ... } With func createLayout() -> UICollectionViewLayout { let config = UICollectionViewCompositionalLayoutConfiguration() config.interSectionSpacing = 20 let layout = UICollectionViewCompositionalLayout(sectionProvider: { (sectionIndex: Int, layoutEnvironment: NSCollectionLayoutEnvironment) -> NSCollectionLayoutSection? in guard let sectionKind = SectionKind(rawValue: sectionIndex) else { fatalError(unknown section kind) } let leadingItem = NSCollectionLayoutItem(layoutSize: NSCollectionLayoutSize(

I have this spaceshooter game where it spawns enemy ships randomly. once the player reaches 30, it would spawn a Boss Sprite. In the original App, I have it set up to where the boss would appear and only move left and right because I ran into an issue with the sprite disappearing once it collided with the bullet.I do not have it set up to where if both contacts were made, it would remove the Boss from parent.I tried to close in on the problem by copying the app and deleting everything besides the player and the boss sprite.The sprite disappears when physicsWorld.contactDelegate = self is set so it is a collision issue.Could this be a bug with the xcode?It is not the image itself because i took out the images and i am using just the placeholder image (big red X) saying that no image of that name was found.Here is a gif of what it looks likehttp://g.recordit.co/8ucvkrwR4Z.gifthe left side of the screen shows the bullets being shot from bottom to top the image coming from right to left is the b

I'm trying to convert an existing Chrome Extension to Safari Web Extension using this converter - https://developer.apple.com/documentation/safariservices/safari_web_extensions/converting_a_web_extension_for_safari. Immediately after convert, xcode opens and I build the project with my developer certificate. Everything looks perfect in Safari: the popup works fine, the context menu item is there, options are there. The moment I restart Safari OR rebuild the project (even without changes), the context menu item disappears. This is how context menu is defined in my context.js script: chrome.runtime.onInstalled.addListener(function() { ttchrome.contextMenus.create({ tttttitle: chrome.i18n.getMessage(contextMenu), ttttcontexts: [selection], ttttid: context + selection tt}); }); chrome.contextMenus.onClicked.addListener(onClickHandler); My manifest.json has this: permissions: [activeTab, storage, contextMenus], I followed these instructions - https://developer.apple.com/documentation/safariservic

Content drawn in the CALayer gets disappeared when UIMailComposeViewController appears over the control. We could reproduce this issue only after upgrading to iOS 11. This works fine in iOS 10 and before.

I have a peculiar situation, where the first time I present a sheet from a Section that has the header: set, the sheet disappears by itself the first time it is presented. @State private var show = false // … List { Section { Text(foo) } header: { Text(bar) } .sheet(isPresented: $show) { Text(baz) } // just to enable Button(toggle) { show = true } } In Xcode I get this warning when I present the sheet (taken from our live app): Attempt to present <_TtGC7SwiftUI29PresentationHostingControllerVS_7AnyView_: 0x10a819e00> on <_TtGC7SwiftUI19UIHostingControllerGVS_15ModifiedContentVS_7AnyViewVS_12RootModifier__: 0x10a020600> (from <_TtGC7SwiftUI32NavigationStackHostingControllerVS_7AnyView_: 0x10a0cba00>) while a presentation is in progress. Tested on iOS 17.4.1, iPadOS 17.4.0 (Simulator), Xcode 15.3 Previews. Circumstances The circumstances are as following: a Section has to be in a List, and have content:, and header: or footer: set to something, and have the .sheet(…) set on the sectio

Hi, Xcode updated and now I can't build any of my projects, it says: Swift Compiler Error - Unable to load standard library for target 'arm64-apple-ios14.5' The options of running iOS devices on the simulator also disappeared. I run my Xcode on the M1 chip. Does Apple, anyone have a solution? h

Hello, my Xcode app has worked just fine for the last few weeks, I have not changed anything and when I run it now, the tab bar disappears when the associated tab is selected, also stuff like the cursor, navigationbarbackbutton are all invisible or white. How can I fix this, not sure if it's an Xcode bug. tab view: init() { let tabBarAppearance = UITabBarAppearance() tabBarAppearance.configureWithOpaqueBackground() UITabBar.appearance().scrollEdgeAppearance = tabBarAppearance } content view: TabView(selection: $selectedTab){ NavigationView(){ FeedView() } .tabItem { Image(systemName: h.circle) }.tag(1) NavigationView(){ JobsView() } .tabItem { Image(systemName: j.circle) .tint(.gray) }.tag(2) }

Our app recently got rejected couple times by an issue that the keyboard is not appeared (or is disappeared after 1 second) on log in page when the reviewer tried to login by using their iOS 15.0.1 device (iPhone or iPad). We can't reproduce from our devices until we connect a Magic Keyboard to our device and found out the iOS 15 has been changed for the behaviour of hardware keyboard: When running the app in iOS 15 and iOS 13 in Simulator, if the Connect Hardware Keyboard is on, typing in hardware keyboard results differently for iOS 15 and iOS 13, iOS 15 keyboard is disappeared from the Simulator. I connect my Magic Keyboard to my iPhone (iOS 15.0.1) and when I tap on a text field (e.g. in Message app) - there is no iOS keyboard appears on the screen. I also sometimes have luck that the iOS keyboard is appeared when I tap on Message app's text field, if the iPhone is awake from the locked screen. Then I can use the iOS keyboard for inputting, but once I start typing in the Magic Keyboard,

I have a UICollectionView where sometimes (about 50% of the time) when the keyboard appears, it causes all of the collection view cells to disappear. This only happens on iOS 16, and the collection view itself maintains its size throughout the keyboard presentation and dismissal, but loses all of its cells. The didEndDisplaying UICollectionViewDelegate method is called for each of the cells that were being displayed. I've tried using both diffable data source and UICollectionViewDataSource implementations. I've tried using keyboard notifications to move the collection view up, and I've tried pinning the bottom of the collection view to the top of the keyboard layout guide. The issue persists no matter the implementation. Given that it works on iOS 15 just fine, and that the issue is non-deterministically happening about half the time on iOS 16, I'm inclined to think it's yet another iOS 16 bug. I've debugged thoroughly, reviewed my code over and over, tried different implementations, and made all kin
