CoreBluetooth Scan not working when OS upgraded to 18.3.1
Hi, I currently have an app that connect to an arduno via CoreBluetooth. However, the app no longer discovers the arduino when the operating system was upgraded to iOS 18.3.1, however on iOS version 17.6.1 the ardiuno was discoverable I was able to test this theory on two different phones each with different iOS versions. I see that it is failing to find the peripheral at the scan however the logs indicate that the central state is powered on. Why are my peripherals no longer being discovered with this update? and what is the solution?

Download Container downloads only partial container
In Xcode Version 16.2 (16C5032a) - and previous versions too, the download container in the Devices & Simulators functionality no longer works. It will start downloading the container, however it will also: show NO download progress fail to download the whole container (the downloaded container is missing whole directories, eg. AppData/Library is missing - where my application stores the CoreData db) show no errors This was tested with the XCode version stated above (and previous versions) and with iPhone XR (18.1.1 - MR42CN/A) and with iPad (17.7.2 - MR7F2FD/A). How can I debug this issue / make the Xcode download the whole container? Running on Mac mini 15.1.1 (24B91).

Xcode quit working
When I try to open Xcode, it tries to open the previous windows and load up the project I was last working on, but I can’t create a new project without opening Xcode, and I can’t do that; it just quits and gives me an Xcode quit unexpectedly, and it still happens when I download earlier versions of Xcode from the Apple developer website and the latest from the App Store, and I even when in Finder and tried to open my project that way, and it just does the same thing. I have tried everything, and I mean everything. I even reinstalled macOS, and it worked for a minute until it tried to open my project and then quit again and is doing the same thing.

Spatial audio personalised profile access entitlement "not available on iOS"
I followed this guide, and added com.apple.developer.spatial-audio.profile-access as an entitlement to the app (via the + Capability button – Spatial Audio Profile). I have a audio graph that outputs to AVAudioEngine. However, the Xcode Cloud build ended up with this error: Invalid Code Signing Entitlements. Your application bundle's signature contains code signing entitlements that are not supported on iOS. Specifically, key 'com.apple.developer.spatial-audio.profile-access' in 'Payload/…' is not supported. This guide says it's available on iOS. Does it mean not on iOS 17? In which case how can I provide fallback for iOS 17?

Xcode crashes when "Build Phases" -> "Copy Files" -> "Copy only when installing" checkbox gets clicked
I've got a very simple command-line Swift project that contains a couple of OpenGL shader source files. They need to be accessed at run-time in order to be compiled and linked. For initial debugging, I hard-coded the absolute path to their location in the Xcode project directory, but I switch back and forth between two machines (MacBook Pro and Mac Studio) for which the project paths are different, so this doesn't work well. To solve this, I thought I could get Xcode to copy the shader sources over with the executable file at build time. I'm aware that technically, command-line apps have no resource bundle, but the "Build Phases" -> "Copy Files" section of the project configuration isn't disabled for my project, so I assumed that it could handle this. I added the two shader source files to the set of files to copy, via the "+" button, and set the Destination to "Products Directory". I left the "Subpath" field blank. AFAICT, nothing happens: the "Products/Debug" sub-directory of "~/Library/Developer/Xcode/DerivedData/..." has the executable, but neither of the shader sources. In fact, they don't appear anywhere inside ~/Library/Developer/Xcode. Okay, perhaps I need to uncheck "Copy only when installing" in the project config? Sadly, as soon as I click to uncheck it, Xcode crashes, even if that's the very first thing I do immediately after Xcode restarts. FWIW, I'm running Xcode 16.2 on a late 2019 MacBook Pro running Sonoma 14.6.1, but I'm pretty sure I've experienced the problem on my 2024 Mac Studio as well.

Fully symbolicate crash log received from App Review
A new app I submitted to review was rejected due to a crash. I cannot reproduce the crash, even running it on exact the same device model used by App Review. So I need to symbolicate the ips crash log they provided me. Using MacSymbolicate and the archive located using Xcode Organizer I was able to partially symbolicate the crash log. To fully symbolicate the crash log, however, according to MacSymbolicate, I would need two more symbol files, which can't be located, because they relate to system frameworks (SwiftData and _SwiftData_SwiftUI). I have tried to follow the instructions provided on https://developer.apple.com/documentation/xcode/adding-identifiable-symbol-names-to-a-crash-report but I had no success. It seems to me that the instructions contained there for symbolicating using Xcode do not apply for crash logs downloaded from appstoreconnect after an App Review rejection. Also, the instructions seem to be out of date, e.g. "To symbolicate in Xcode, click the Device Logs button in the Devices and Simulators window.": This button was replaced by "Open Recent Logs", which opens what seems to be a different window (according to some online research). Is it possible to fully symbolicate such an ips file downloaded from App Review team? If so, how can this be achieved? Thanks This is how the partially symbolicated crash log looks like: Hardware Model: iPad13,16 ... AppStoreTools: 16C5031b Code Type: ARM-64 (Native) Role: Foreground Parent Process: launchd [1] ...

Non-deterministic xctestplan files
Working with .xctestplan files reminds me very much of working with project files and nibs and storyboards back in the day 😅 It seems that they are non-deterministic. This means that every time we add a new test module or edit the inclusion rules at all the whole file is recomputed. But it doesn't have a fixed order so everything in the file changes. It makes it very difficult to see what has happened in PR reviews and causes conflicts any time anything is changed. TBH... because it isn't alphabetical, even just finding a particular test suite is difficult without changes. Are there any plans to bring this file format up to date with the likes of xcodeproj and xib files? It would help massively while working with source control in a larger team. Thanks

How to create a new asset catalog in a package
I created a package using "File > New > Package" and now I want to add a new Asset Catalog to this package. With my package selected in the project navigator I select "File > New > File" but it creates a Swift file instead of showing the Template Selection dialog Ref: https://developer.apple.com/documentation/xcode/managing-assets-with-asset-catalogs#Create-a-new-asset-catalog

FamilyControls Framework info.plist missing
We are trying to create a screentime app using the Family Controls as well as Device activity frameworks. The build succeeds but while pushing to an iphone we are getting an info.plist file for deviceactivity.framework could not be found error. For reference when using the Screentime API a physical device must be used not a simulator. When we remove the device activity framework this error also occurs for the family controls framework. We have added the Family Controls(development) Capability and applied for the distribution capability. We have redownloaded xcode multiple times on the main device, deleted derived data, and redownloaded all of the iphone SDKs and the issue still persists.

CoreData in Swift Packages
I am having issues loading my model from a Swift Package with the following structure: | Package.swift | Sources | - | SamplePackage | - | - Core | - | - | - SamplePackageDataStack.swift | - | - | - DataModel.xcdatamodeld | - | - | - | - Model.xcdatamodel ( <- is this new? ) As mentioned, I am not required to list the xcdatamodeld as a resource in my Package manifest. When trying to load the model in the main app, I am getting CoreData: error:  Failed to load model named DataModel Code: In my swift Package: public class SamplePackageDataStack: NSObject {     public static let shared = SamplePackageDataStack()     private override init() {}     public lazy var persistentContainer: NSPersistentContainer = { let container = NSPersistentContainer(name: "DataModel") container.loadPersistentStores(completionHandler: { (storeDescription, error) in             if let error = error as NSError? {                 fatalError("Unresolved error \(error), \(error.userInfo)")             }         })         return container     }()     /// The managed object context associated with the main queue.

tvOS icon missing layers
I have an AppleTV app which I released in 2016. I've updated it and released a new version every year without much hassle. This year, with tvOS 17.2, the layered app icon isn't working right. This is a two-layer image made with PNGs. When it's selected, it looks right and the layers move correctly: But when it's not selected, the background layer disappears: Screenshots are from the simulator but it also happens on the device. It's inconsistent; sometimes it's the front layer that disappears. Occasionally both layers work, but I can't tell why. I've spent a day trying everything. Very frustrated. The icon previews correctly in Xcode and in Parallax Viewer. The image sizes are correct: 400 x 240 for Small, 800 x 480 for Small@2x, 1280 x 768 for Large. The back layer is a non-transparent PNG. I tried adding a Large@2x set. Didn't help. Originally I had a three-layer image with no middle layer PNG. I deleted the empty middle layer, but that didn't help. All the PNG files are from GnuIMP. Same color space, even. I was using the filenames tvicon-back-s.png and tvicon-back-s@2x.png. I tried taking out the @ sign in case that was confusing Xcode. (It never has before, but I am flailing here.) Anybody have any clues? If it's an Apple bug and there's nothing I can do, I'm going to just push the release button and hope it fixes itself someday.

There is no longer a Frameworks and Libraries section for App Extensions with Xcode 16
I've got an existing app which is using some 3rd party xcframeworks within its app extensions (for example within a Notification Service Extension). Within the target for the app extensions there is a Frameworks and Libraries section where the xcframework was dragged and dropped into. However now I want to create a new project and do a similar thing, within the app's target there is a Frameworks and Libraries section, but when an app extension target is created, Xcode is not adding a Frameworks and Libraries section. There is a Link Library with Binary section, however this doesn't have an embed section (where you can select to embed, don't embed, embed without signing etc.) and I get build error trying to drag and drop the xcframework in here. Where id the Framewoks and Libraries section go for app extensions for projects created with Xcode 16? How can this section be added?
