Is anyone else seeing their apps crash on iOS/macOS 17.4/14.4 and newer when building a project that simply just includes the iOS 18 @AssistantIntent Macro? The beta 4 releases still have this problem. There are no notes about this that I have seen in the beta release notes. Crash message shown in console when trying to run on 17.4, 17.5, 17.5.1, etc: dyld[21935]: Symbol not found: _$s10AppIntents15AssistantSchemaV06IntentD0VAC0E0AAWP Referenced from: <F7A1FEF0-F3B0-379C-A914-D1FB0BA7C693> /Users/jonathan/Library/Developer/CoreSimulator/Devices/CA308F47-BCA8-4429-8599-1BB1CCEAB5B6/data/Containers/Bundle/Application/D7DC8E16-90DB-406A-A521-20F18326E4A7/IntentDemo.app/IntentDemo.debug.dylib Expected in: <88E18E38-24EC-364E-94A1-E7922AD247AF> /Library/Developer/CoreSimulator/Volumes/iOS_21F79/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/AppIntents.framework/AppIntents Obviously, the new Apple Intelligence AssistantIntents only work on the 2024 OS releases. However, even when these new App Intents are marked with @available(iOS 18, macOS 15, *), the app crashes on any earlier OS version. But it runs just fine on iOS 18 and macOS 15... I would love for me to just have done something wrong but I don’t think I have… Here is the sample project: https://github.com/JTostitos/FB14323923 Maybe it's a compiler issue thats failing to strip out the macro when building for older OS's or an Xcode issue - I have no idea. I just would like to know why its not working and how to resolve it. Thanks in advance for anyones help...

I was curious as to the procedure for having an encryption key leaked and was hoping to have your opinions on how these two questions will be answered [if you were in the position]. Q1: Let's say, for instance, that you're making a social media network that stores private messages in a database network (such as Firebase) and uses basic encryption to store that data into an encrypted format (e.g., text message: "Hello Mous772!"; Firebase data: "deaErG5gao7J5qw/QI3EOA=="). But oh no! Someone got access to the encryption key used to encrypt hundreds of thousands of messages. You cannot simply delete thousands of messages because of this hacker, so how should you deal with this? This is where my question comes in. Is it possible to change the encryption key for all of the data if I am using the code system at the bottom of this question and using that code system to store encrypted data in Firebase? If so, how would you go about doing that? (Please use simple language; I'm not good with this stuff). Q2: What, in your opinion, is the best way to prevent this in the first place? I was told that a good solution was to store two sets of the same data; when one kegs it, we shut down the original and use the backup; however, this does not sound sustainable at all. I want to know what steps can be taken to ensure this never happens. [Please don't give me "Well... you can never *really hide these keys!" I'm well aware it's not possible to never have them leaked ever; I'm just looking for best practices only.] This is the encryption system we are using for this hypothetical app. // MARK: Value // MARK: Private private let key: Data private let iv: Data // MARK: - Initialzier init?(key: String, iv: String) { guard key.count == kCCKeySizeAES128 || key.count == kCCKeySizeAES256, let keyData = key.data(using: .utf8) else { debugPrint("Error: Failed to set a key.") return nil } guard iv.count == kCCBlockSizeAES128, let ivData = iv.data(using: .utf8) else { debugPrint("Error: Failed to set an initial vector.") return nil } self.key = keyData self.iv = ivData } // MARK: - Function // MARK: Public func encrypt(string: String) -> Data? { return crypt(data: string.data(using: .utf8), option: CCOperation(kCCEncrypt)) } func decrypt(data: Data?) -> String? { guard let decryptedData = crypt(data: data, option: CCOperation(kCCDecrypt)) else { return nil } return String(bytes: decryptedData, encoding: .utf8) } func crypt(data: Data?, option: CCOperation) -> Data? { guard let data = data else { return nil } let cryptLength = data.count + key.count var cryptData = Data(count: cryptLength) var bytesLength = Int(0) let status = cryptData.withUnsafeMutableBytes { cryptBytes in data.withUnsafeBytes { dataBytes in iv.withUnsafeBytes { ivBytes in key.withUnsafeBytes { keyBytes in CCCrypt(option, CCAlgorithm(kCCAlgorithmAES), CCOptions(kCCOptionPKCS7Padding), keyBytes.baseAddress, key.count, ivBytes.baseAddress, dataBytes.baseAddress, data.count, cryptBytes.baseAddress, cryptLength, &bytesLength) } } } } guard Int32(status) == Int32(kCCSuccess) else { debugPrint("Error: Failed to crypt data. Status \(status)") return nil } cryptData.removeSubrange(bytesLength..<cryptData.count) return cryptData } } //let password = "UserPassword1!" //let key128 = "1234567890123456" // 16 bytes for AES128 //let key256 = "12345678901234561234567890123456" // 32 bytes for AES256 //let iv = "abcdefghijklmnop" // 16 bytes for AES128 //let aes128 = AES(key: key128, iv: iv) //let aes256 = AES(key: key256, iv: iv) //let encryptedPassword128 = aes128?.encrypt(string: password) //aes128?.decrypt(data: encryptedPassword128) //let encryptedPassword256 = aes256?.encrypt(string: password) //aes256?.decrypt(data: encryptedPassword256)

I would like to include the bottom sheet from the iPhone "find my" and "maps" app in my app. During my research I came across the new modifier .presentationDetents for sheets. The only problem here is that you can no longer interact with the main screen when the sheet is active. In my app, however, I would like the sheet to be active all the time like in the iPhone apps mentioned and that you can still interact with the main screen like in the iPhone apps with the map. I would be very happy about help. Greetings

I am building and running a simple Open MPI C application. In order to run it, I configured the run process in this way:\ Edit Scheme -> Run -> Info -> Executable -> Other... -> /path/to/mpiexec Edit Scheme -> Run -> Arguments -> Arguments Passed On Launch -> -np 4 "$(BUILT_PRODUCTS_DIR)/$(EXECUTABLE_NAME)" Now, instead of the hardcoded "4" as the number of processes, I want to specify an environment variable (like the already existing BUILT_PRODUCTS_DIR and EXECUTABLE_NAME environment variables), so I enter in Environment Variables NUM_PROCS as Name and 4 as Value. Thus, I write in Arguments Passed On Launch the whole quoted string: "-np" "$(NUM_PROCS)" "$(BUILT_PRODUCTS_DIR)/$(EXECUTABLE_NAME)". And Xcode can't read the NUM_PROCS environment variable (despite I can easily read it in the C program by a getenv("NUM_PROCS")!), in fact, it runs the default number of processes of my system (12). I tried in a very large number the different ways of writing arguments (every string on a new line, with quotes, without quotes, ...), but none worked as I expected.

Hello, Dear Developers Problem Description My team is working on functionality test in iOS18. Basically, application functionality works as expected without any modification. However, We found a small issue in settings application. iOS 17 In iOS17, 3rd party OSS license string in settings application would been displayed if the license button is been clicked. Model: iPhone SE 3 OS Version: 17.6.1 iOS 18 However, in iOS18, nothing but a blank page. Model: iPhone SE 3 OS Version: 18.0.1 Settings.bundle Below are files in settings.bundle. What I've searched Using XCode 16 makes no change Nothing about settings.bundle in iOS 18 release note A similar post: https://forums.developer.apple.com/forums/thread/764519 The solution in the post doesn't solve my problem. If you know the solution, please let me know. Best wishes.

With Xcode 16 I cant make the Final Cut Extension Workflow work. I am quite sure I was able to add the Workflow Extension target a couple of months ago in Xcode 15 and did successfully build it, but in Xcode 16 it wont build and it fails with this error: clang: error: unknown argument: '-e_ProExtensionMain' I have installed multiple times Workflow Extensions SDK 1.0.2 and even disabled Library validation like its described in the release notes but I dont think thats the problem here. Seems like clang doesn't have the arguments for it, I guess the SDK should add these but seems like something got messed up - the template shows up fine in Xcode. I reinstalled Xcode and command line tools but that didnt help. Checking clang it really doesnt have the argument. But where does the SDK add this? Xcode seems to be using internal clang and /usr/bin/clang doesn't have it either. Any tips what could be the problem here? I was not really able to locate the SDK to remove it before trying to install again - any ideas? Steps to reproduce Create new project Add FCP workflow extension target Build -> it fails Same behaviour with 16.1 Beta. I am running Sonoma 14.7. Thanks in advance for any ideas!

I am getting this error while archiving the app. This is happening after upgrading to the latest macOS Sequoia and XCode 16. getting this error. env: node: No such file or directory Command PhaseScriptExecution failed with a nonzero exit code It was working when I was in XCode 15.4.

I encountered an issue when implementing the WKUIDelegate protocol and NSItemProviderWriting protocol. Below is a minimal example of the code that reproduces the issue: import UIKit import WebKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. } } class ItemProvider: NSObject, NSItemProviderWriting { static var writableTypeIdentifiersForItemProvider: [String] { fatalError() } func loadData( withTypeIdentifier typeIdentifier: String, forItemProviderCompletionHandler completionHandler: @escaping @Sendable (Data?, (any Error)?) -> Void ) -> Progress? { fatalError() } } extension ViewController: WKUIDelegate { func webView( _ webView: WKWebView, runJavaScriptAlertPanelWithMessage message: String, initiatedByFrame frame: WKFrameInfo, completionHandler: @escaping @MainActor @Sendable () -> Void ) { fatalError() } } When implementing the WKUIDelegate protocol after NSItemProviderWriting protocol, the following warning appears: Instance method 'webView(_:runJavaScriptAlertPanelWithMessage:initiatedByFrame:completionHandler:)' nearly matches optional requirement 'webView(_:runJavaScriptAlertPanelWithMessage:initiatedByFrame:completionHandler:)' of protocol 'WKUIDelegate' The target's SWIFT_VERSION is 6.0.

I made an update to my app's code to make use of the new Contact access limited permission (CNAuthorizationStatusLimited), like so: if (@available(iOS 18.0, *)) { switch ([CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts]) { case CNAuthorizationStatusLimited: <snip> However, later I discovered there's another totally unrelated issue which only manifests when the app is built with XCode 16. It isn't a trivial change to workaround, so for now I would like to make a release to the app store which makes use of the new CNAuthorizationStatusLimited status but is built using XCode 15. However, building with XCode 15 results in a "Use of undeclared identifier 'CNAuthorizationStatusLimited' error. If the code were making use of a new API, I could workaround using a selector for example, however as this is an enum, is there Is there any workaround possible for this - or its just not possible to build using XCode 15 and the source code contain references to CNAuthorizationStatusLimited?

I get this error from time to time in UI tests when they are run on CI. Any ideas what might be causing this error?

The macOS build is available in TestFlight. But when I go to App Store Connect to prepare it for submission, I don't see any macOS version in the "Build" section.

In Xcode 16.0 and 16.1 beta 2, running on macOS 15.1 beta 4, Developer Documentation for Objective-C is (at least partially) missing in the Navigator. Many of the entries appear to be for Swift. In Xcode 16.1 beta (i.e. beta 1), the documentation is normal. I did not find any posts in this forum about this, which is surprising and makes me wonder if the issue is isolated to particular configurations. In any event, I would appreciate any information anyone may have about this.

I have not been able to open any of my apps since I uploaded my latest update midOctober 2023. Previously I have tried everything on forums from removing derived data, adding new options in build folder and more. Since then I have wasted hours trying to open any app from my iCloud / hard disk and I wonder if part of the problem is caused by backing up to iCloud, as I can open from an external hard disk. It takes almost as long to upload from hard disk than cloud so whole thing annoying, does this add clues to this frustrating problem ? Also when I opened one of my apps it had made hundreds of unassigned assets that all had to be removed individually. I have no idea how to continue with my work I have three other apps in progress, but am halted at present but such a stupid small detail. // here is full commet /Users/ruwickigmail.com/Desktop/0-APPS-2023/InstaAnimates/InstaAnimates.xcodeproj: warning: Unable to find a target which creates the host product for value of $(TEST_HOST) '/Users/ruwickigmail.com/Desktop/0-APPS-2023/InstaAnimates/DerivedData/InstaAnimates/Index.noindex/Build/Products/Debug-maccatalyst/InstaAnimates.app/Contents/MacOS/InstaAnimates' (in target 'InstaAnimatesTests' from project 'InstaAnimates') My bundle ID is fine but it crashes on loading so may be due to something in signing but everything looks fine. I note that there are hundreds of enquiries on the forums, but most are unanswered. as this is an regular Xcode Apple problem and there are hundreds of people being put of continuing with their apps could the Apple team look into this please.

I have the newest Xcode and macOS. When I'm trying to check Pull Request changes then when I click on any changed/added file, then instead of view with file I see infinite spinner. This happened in all files. I've tried to reinstall Xcode, macOS, clone new repo. This feature works once per 10-20 tries. Also when I try to manually compare uncommitted changes to some commit in Code Review mode, then I don't see any changes and no error appears. When I use git command line command in terminal, everything works and I receive changes. What can I do to fix this problem? I've tried Xcode 16.1 beta, and I can't go back to Xcode 15. Anyone has this problem? Anyone has any ideas?
