I created an application in xcode 13, and I need to install it on my iPhone 12 iOS 18. I already went to the Apple Developers website and downloaded the files iOS_17.5_Simulator_Runtime.dmg and also the file iOS_18_beta_Simulator_Runtime.dmg I copied them to the folder on my Mac /Library/Developer/CoreSimulator/Profiles/Runtimes/ And even so, when I opened xcode and went to deployment info, the most recent iOS version is still 15.2 and the last one I downloaded doesn't appear. what should I do ? I preferably want to install iOS 18 beta on my iPhone 12

I've been trying to add an 'Info.plist' file this afternoon and get a recurring error that I haven't seen before. I see a lot of other people have posted similar errors over the time but I con't seen any solutions posted. I'd appreciate anyone reading this giving it a boost to perhaps have an engineer post a solution so others will not waste as much time on this as I have. . Info.plist has the proper path, I do not have a 'script phase' or 'custom build rule', and I don't know what "Did you forget to declare this file as an output of a script phase or custom build rule" means. I've had Info.plists before, I'm just not sure why I'm getting this error or how to bypass it.

How to set Tx power level for iphone

An app I'm developing uses a text data file to access some words. The app runs fine in all simulators and when directly hard-wired from my Mac to my iPhone. When I download it to App Store Connect and run the app in TestFlight the app runs fine except when it tries to access the data file. The error it gives me is that it can't access the same data that I access when running the app in the simulators.

As of a few weeks ago or so I'm finding it hard to test my apps in the simulator or on test devices. When I try to sign into iCloud (my apps use CloudKit) or sometimes even make a sandbox StoreKit purchase, I get a "unlock account" alert that refers me to one of my real devices, which then prompts me to change my password. I did that once but then the next day it wanted me to change the password again. Is this expected, and if so how are developers expected to handle this?

I've been contacting Apple Developer support for over 3 weeks now regarding new agreement that is not visible anywhere in account and no option to accept it either. Submitted ticket twice but no response at all. All they have to say is "Thank you for contacting us. We’ve received your support request and will get back to you as soon as possible. Your case ID is 102320028158. If you have any additional information you’d like to provide or would like a status update on your case, please reply back to this email."

I'm following the guidance from [wwdc24/10171] using Xcode 16 beta 2 on Sonoma (https://developer.apple.com/wwdc24/10171) and find myself unable to active the _EXPERIMENTAL_SWIFT_EXPLICIT_MODULES = YES setting. I tried both in the project file and in the XCConfig file and nothing. After cleaning and building with timing summary, I can't find any "Compiling Swift module" nor any "modules report". I only get multiple statements of "Compiling clang module" and the "GenerateClangModulesReport" What am I doing wrong?

Feedback on Documentation Page for Message Filter App Extension Documentation: Creating a Message Filter App Extension Hello, I am writing to provide feedback on the documentation for creating a message filter app extension. We followed the instructions on the page, particularly the section regarding setting up shared credentials. The instructions state: "Then, you must set up shared credentials as described in Shared Web Credentials, substituting messagefilter for webcredentials throughout the steps. Lastly, you must specify the domains in your Info.plist file, which should look similar to the dictionary shown below." However, when we tried to implement this, we encountered the following error while attempting to save credentials via the SecAddSharedWebCredential function from the message filter extension: Error Domain=com.apple.security.xpc Code=3 "<connection: 0x12e0d4500> { name = com.apple.securityd, listener = false, pid = 0, euid = 4294967295, egid = 4294967295, asid = 4294967295 }: Connection invalid - failed at lookup with error 159 - Sandbox restriction" UserInfo={numberOfErrorsDeep=0, NSDescription=<connection: 0x12e0d4500> { name = com.apple.securityd, listener = false, pid = 0, euid = 4294967295, egid = 0, asid = 4294967295}: Connection invalid - failed at lookup with error 159 - Sandbox restriction} The specific call we did: func SecAddSharedWebCredential( _ fqdn: CFString, _ account: CFString, _ password: CFString?, _ completionHandler: @escaping (CFError?) -> Void ) This error seems related to sandbox restrictions. The documentation does not provide enough information on how to properly set up the environment or what additional configurations might be needed to avoid such sandbox restrictions. More detailed guidance on configuring sandbox permissions and any additional steps required for setting up shared credentials in a message filter extension context would be highly beneficial. Thank you for your attention to this matter. We look forward to any updates or clarifications you can provide to improve the implementation.

The in-app purchase is not working. I am trying to create auto-renewable subscriptions, but all I see is "The subscription is unavailable in the current storefront." I have checked and signed all agreements available to me in App Store Connect. They are all in "Active" status. I created subscriptions in App Store Connect (they are all in "Waiting for Review" status). All countries or regions are selected in the subscription. Subscription Prices, Tax Category, and App Store Localization are set. When building in Xcode, I set the StoreKit Configuration to None in the scheme. The app was installed via TestFlight. I submitted the app for review, but the reviewer also couldn't use the purchases. I've already watched all the videos on StoreKit v2. I don't know what else I can do.

I am trying to send a app build to appstoreconnect through VisualStudio, this used to work some months ago but now I get this error every time. The provided entity includes an attribute with a value that has already been used What is strange is that everything worked fine a couple of months ago. I have tried incrementing the version numbers but to no avail. I have also been through all the agreements and accepted them all.

The application crashes and displays the error "SIGNAL 6:Abort trap:6" while it is in movement.

I need to access notification data that accumulates in the Notification Center, similar to text messages, through BLE communication in my app. How can I achieve this?

I want to retrieve processor features at runtime. I used 'MRS' instruction to access system registers. But it failed on my M1 MacBook. I tried the same code on Nvidia Orin(ARM ISA), it's works. On MacOS, I found only 'NZCV' system register I can access. Does Apple impose limitation on other system registers?

Hi, I am consuming the API https://gdmf.apple.com/v2/pmv to get the supported apple OS versions. I do get intermittent 403 exception almost every alternate day. Is there any way to fix this issue for this API? Is there any better and reliable Apple API to get supported apple OS versions across macos, ios etc?

I have been able to get rid of reported memory leaks in Instruments not by fixing a leak but by adding some lines (like releasing a previous nil object) that convinced Instruments it is not a leak. But I am stuck are some I cannot stop Instruments from reporting. It reports a leak in this code if(expr.length>0) { // add previous Atomic Atomic *atom = [[Atomic alloc] initWithString:[string substringWithRange:expr] isNumber:aNum]; [exprTokens addObject:atom]; [atom release]; } } and it underlines the substringWithRange method. I changed code to explicitly release atom and I assumed substringWithRange would return an autoreleased new string. I am aware Instruments tells you where the leaked object is created and not where it is leak, but only things created here are atom and a sub string and atom is released immediately. The initWithString method might do it, but I don't find anything there. Also, while running instruments, this code is 8542 times (I am pretty sure always in the same context) and Instruments says it only leaks 61 times. I don't now if there is misunderstanding are a code problem?
