Recently, our team bumped into a crash that we cannot resolve. We looked for help everywhere. I asked people here on forums, team asked about 10 fellow developers and the question on SO was created. Nobody knows the reason for the crash, nobody can find a workaround. So, as the last resort, I called for Apple Technical Support (aka code-level support). I assumed that people there understand how things work under the hood. Considering that this service is limited (2 TSI per year, otherwise paid), I expected the quality to be high. In fact, it didn't help us to resolve the problem, and I was disappointed how irrelevant the provided support could be. TLDR: The dev didn't even open the test project! I described the memory crash with WidgetKit-based complication. I spend my time capturing video, finding watch logs on my iPhone and creating a sample project. I attached console output, stack traces and a couple of screenshots. I even provided a .watchface file, so they can reproduce the configuration. This together took about 6-8 hours of work. I explained what happens in detail: steps to reproduce, what I've tried. I asked the support to recommend me way to present only the specified complications. Then I submitted the issue and started to wait. It took them 1 week to responsd. I pointed my sight on the email with excitement, expecting to finally get the resolution. But what I found there was disappointing. The software engineer, Rico, quoted only a couple of sentences from my list. His letter contained only 4 lines of text (not including greetings and cheers). In the first line he recommended to use preprocessor macro to enable only necessary complications, which is nonsense. Of course we need to change complications dynamically, when the user selects them. I two next lines he recommends to use if statement in WidgetBundle to dynamically unlock the complications. I already knew that it isn't possible. Because, quote: "if statements in a WidgetBundleBuilder can only be used with #available clauses" @available(*, unavailable, message: "if statements in a WidgetBundleBuilder can only be used with #available clauses") public static func buildOptional<W>(_ widget: W?) where W : Widget The last line cancelled everything before, Rico said that this can't be done at runtime. Probably, he added that after reading the documentation, but forgot to edit his previous statements. I didn't give up completely. I decided to skip the design discussions and get the info that Rico could probably have, due to his access to the software. Why the extension using so much memory? I also asked him, if he was able to build the project and reproduce the bug. Another week passed. I'm sending a follow-up message. That worked, after another 3 days I got the response: Finally some useful information! Timeline and views are being archived to disk (all simultaneously), that's why the memory usage is so high. Basically, a widget design issue. But anyway, we have what we have. Then next line, he has written this: "Complications are deprecated". What? But wait, he thinks that we use ClockKit, and recommends migrating to WidgetKit. So Rico completely forgot that we discussed WidgetBundle and SwiftUI before 🤡 He honestly tells me that he didn't open the project. Why? Because "Complications are unlikely to be supported", he says. So he "forgot" WidgetKit on intention, this gave him an excuse to ignore the sample project. My time was invested for nothing! I believe there's no need in further conversation with Rico. I will provide the detailed feedback to the Apple. And I'm posting it publicly to make sure that Rico gets the attention he deserves.

Excuse my English. In Greece where I live the apple service is terrible and you can't find a solution. After using android for 15+ years I decided to switch to iphone (iOS) and got the shock of my life. The obvious settings that exist on android on iOS do not exist. For example I have a lot of trouble with the keyboard keys, because it has small keys, I almost can't type text. The settings from "Accessibility" (I'm considered rather handicapped) to enlarge text (I don't know if it also enlarges the keyboard) spoil texts in apps e.g. in X). Also in Greek it doesn't give the possibility to change the layout and I am forced to use Google's gboard or Microsoft's SwiftKey. Also in Adobe Acrobat the list of files in the cloud is flickering. https://www.youtube.com/shorts/Z3s-XpswXe4 ...and the service for printing https://youtube.com/shorts/-3w8-ycR-dc?si=JpJ0mQTeGOaX6DA8 Incredibly stupid problems!

We applied for us company and the following warning has been appearing for weeks; Your enrollment is being processed. Does anyone work at Apple? Apple are you there? Can you hear us?

I am new to iOS/Apple development, and not much familiar with Apple Ecosystem around development. I am facing an issue where my client want to deploy his application on Apple Store, me and my client are in separate countries. I am not sure should I, or can I use my Mac to register an Apple ID for him, and then enroll him in enterprise developer program? As a contractor what is the right way to go about enrolling my client or the client should do it himself?

Hello, I am working on a new App for my company that will be available for iOS and Android. I develop it in Visual Studio using .NET MAUI. I can deploy my development version of the App on an Android device without issues, but when I try to deploy to an iPhone, a dialog wants my Apple credentials. I was invited as a developer in Business Connect by the product manager. The account that invited me is already used for publishing several Apps the company made in the past. I log in with my new Apple developer account, confirmed all legal notices, but when I try to connect to the iPhone from Visual Studio, I get the following error. The Apple account is used for publishing Apps and I was invited as a developer. Do I need to enroll to the Apple Developer Program with my new account just to test the software on my iPhone?

I have an enterprise app that on 95% of devices, I can trust, verify and run the app . On the other 5% the app remains not verified after using the verify app button. The 2 devices I am testing with are both are running ipadOS 17.3.1. The one that can verify the app is a ipad pro (11-inch) and the other is an ipad pro (12.9-inch). I follow the exact same steps on both devices and the 11-inch always verifies and the 12.9-inch never verifies. On the ipad that does not verify, when I try to open the app I get a popup saying "unable to verify app An internet connection is required to verify trust of the developer" when the ipad has a valid internet connection.

Recently Apple deprecated the NXFindBestFatArch, used to find the most compatible / appropriate slice in a universal/fat binary. However its replacement macho_best_slice is broken and will return EBADARCH for any non-Apple binary 😓 The issue seems to be that the dyld3::GradedArchs::grade method does not take into the account the nuances of the CPU sub types of type *_ALL. Namely that any CPU with a more specific sub type (e.g. CPU_SUBTYPE_ARM64E) can also still execute code compiled with a CPU sub type of *_ALL (e.g. CPU_SUBTYPE_ARM64_ALL). All the details (+code, +debugging, +disassembly) posted at: https://objective-see.org/blog/blog_0x80.html. Also, hrmm!?:

Hi there, Hope you're all doing great. It's been a while since we've submitted a request for an Apple Developer Enterprise Account creation. Until today, no email was received and it's showing since a week now that thy're still procession the request. We've sent an email to the Support Team but no response till today. we don't know if there's any issue with the data submited. What else can we do? How much time do they generally take to process account creation request? Thanks

Hello everyone For a year now my partner and I have been having problems receiving payment from Apple. For a whole year we have been writing letters to the mail and not getting a constructive and clear answer. For the last 4 months we have stopped receiving any answers at all. Can you tell me who has had problems with Apple ignoring our letters? What to do in such a case

I encountered an error while saving after modifying the sales region. I used the developer mode of Safari browser to view the error message on the webpage and found that your API: bulkUpdateAppAvailability has a status: "409" error issue.

Hi Team, I have been working on an application that includes a Network Extension. I wanted to disable it if a captive portal is detected over the network. I have tried different approaches to detect it, including the standard approach outlined in the following document: https://datatracker.ietf.org/doc/html/draft-ietf-capport-api, using the URL https://captive.apple.com/hotspot-detect.html. However, none of these methods seem to be working. Additionally, the kSCNetworkReachabilityFlagsConnectionRequired flag is not being flagged when under a captive network. Could you please assist with this issue? Thank you.

Hello, I am currently testing the com.apple.configuration.app.managed declaration, and have failed to get it to work with either VPP OR Enterprise apps. (Testing is being conducted on an iPhone XR with iOS 17.3.1) VPP: Initially errors where returned due to not having a license for the device, so I have set it up to fetch a license before the declaration is return to the device. Said declaration is as follows (I have attempted to switch from Device to User VPP type, as well as attempting to use BundleID or AppStoreID but all have the same result: { "Identifier": "BBC_Test_Install", "Payload": { "AppStoreID": "377382255", "InstallBehavior": { "Install": "Required", "License": { "VPPType": "Device" } } }, "ServerToken": "...", "Type": "com.apple.configuration.app.managed" } The configuration above successfully applies on to the device, and can be seen in the configurations tab in Settings. The install is unsuccessful however, as the app.managed subscription item returns the following result: "app" : { "managed" : { "list" : [ { "state" : "failed", "declaration-identifier" : "BBC_Test_Install", "identifier" : "uk.co.bbc.newsuk", "name" : "BBC News - UK & World Stories" } ] } } The device does not provide any additional information, it was initially returning the following reason when I did not request a licence before the install: "code" : "Error.LicenseNotFound" but this has disappeared now that a licence is requested before hand. No other information can be gleaned so I am at a bit of a loss. It should be noted, I am wipping my device between each test, just to try and get it working on a "fresh" application before attempting to deal with updating the declaration. Enterprise: This also does not seem to be behave, the configuration states a successful application, but it cant be seen in the declrations tab within general settings: "active" : true, "identifier" : "Enterprise_Test_Install", "valid" : "valid", "server-token" : "..." The associated configuration is as follows: { "Identifier": "Enterprise_Test_Install", "Payload": { "InstallBehavior": { "Install": "Required" }, "ManifestURL": "https://my.domain/web/mdm/ios/enterpriseplistgenerator/bundle.id" }, "ServerToken": "...", "Type": "com.apple.configuration.app.managed" } I have had previous success installing enterprise apps through MDM commands so I would have assumed the ManifestURL should have worked the same. The above URL does cause the device to make a secondary request for the application manifest, which returns the following: <?xml version="1.0" encoding="UTF-8"?> <plist version="1.0"> <dict> <key>items</key> <array> <dict> <key>assets</key> <array> <dict> <key>kind</key> <string>software-package</string> <key>url</key> <string>https://my.domain/web/mdm/ios/enterpriseipa/bundle.id</string> </dict> </array> <key>metadata</key> <dict> <key>bundle-identifier</key> <string>bundle.id</string> <key>kind</key> <string>software</string> <key>subtitle</key> <string>testapp</string> <key>title</key> <string>testapp</string> </dict> </dict> </array> </dict> </plist> Which the device then does nothing with (app.managed does not report back anything). When installing the enterprise app through MDM commands the above plist does cause the device to make a secondary call to fetch the applications IPA. Some additional information, help, or insight would be useful, as from my perspective the declaration does not seem to work at all.

I have a shell script that turns a framework into a plain dylib and updates some dependent library paths using install_name_tool. It works, but if the framework was signed, I get warnings like: install_name_tool: warning: changes being made to the file will invalidate the code signature in: [redacted].dylib (for architecture x86_64) I thought I could get rid of the warning by adding codesign --remove-signature dylib-path to the script before using install_name_tool, but then I get errors like install_name_tool: fatal error: file not in an order that can be processed (link edit information does not fill the __LINKEDIT segment): [redacted].dylib (for architecture x86_64) Is there a way to fix this?

iPhone first? Or iMac first? Feedback Assistant is Broken Again (GRRR!!) and I have to reset my iCloud Pwd - which device should I change it on first? iPhone first? Or iMac first? Feedback Assistant is Broken Again (GRRR!!) and I have to reset my iCloud Pwd - which device should I change it on first? This is the question that led me to start this thread: Why is Apple forcing me to change my Appl… - Apple Community Apple is not 'forcing' me to, of course - although I have no choice - I can only recommend to everyone that they AVOID FEEDBACK ASSISTANT LIKE THE PLAGUE until some hack can be found to delete the utterly useless thing: every time I try to sign into it, it forces me to reset my pwd - and then refuses to recognise the freshly minted pwd - and I ABSOLUTELY GUARANTEE I have done this enough times to be certain that it is a Feedback Assistant fault - and a huge one - I'm on Sonoma 14.4 Public Beta. So, having done this utterly unnecessary dance at least fifteen times over the past couple of weeks, and been caught in #AnotherAppleGotcha time and time again (for example, reset pwd on iMac, then sign out of iCloud on iPhone, only to have my exact (copied and pasted) fresh pwd rejected by iPhone), I really would like to know the correct order to do this in - please, please, I'm on my knees here! Perhaps it would be easier to erase the hard disks on all my devices, reload from Time Machine or something - or start with a fresh, ****** Apple ID, and get the Geniuses at the Bar to transfer all my licenses . . . Only joking - but, come on Apple, you can do better than this! And, just by the by, why does the Apple Community website, when asking me to choose which of my (fifteen) Apple devices, offer me first on the list, three MICROSOFT PCs as possible subjects of this problem??? !!!! So - I've reset the pwd on the iMac - all cool after an NVRAM reset and a bit of grunting - but I now have an iPhone which is signed in on the old pwd - and I have updated the OS with an out-of-date pwd - should I sign out and sign in again? (Which, by the way, triggered mayhem last time I tried it) or just wait until some crucial moment like checking in at an airline terminal, only to find I'm locked out of my entire system again? Nobody knows. There's nothing - I've even search the smelliest corners of the DarkWeb - nothing at all . . .

I was trying to run some c++ code on clang (I have command line tools installed) but it just showed this error: Undefined symbols for architecture arm64: then it showed bunch of random gibberish here is my code: #include <iostream> #include <vector> using namespace std; typedef std::string type_t; int main(){ type_t name = "Yashar"; cout << "Hello " << name << '\n'; return 0; }

I am new to Xcode and trying to learn and having issues with errors it seems. I believe the problem is specifically with my code not being able to be displayed on the example iPhone on the right hand side of the screen. Here are the 2 errors I receive below. The codes at the very bottom are red on my screen so I am guessing those are what is most important out of all of this. Thanks and please let me know if I can answer any additional questions regarding this.
