Developer Disk Image could not be mounted on this device
I have been working on a M1 Mac mini, using my iPad Air M2 running 26.3 iPadOS. Switched to a new M4 Mac mini, went to connect my iPad to run from Xcode and was presented this "The developer disk image could not be mounted on this device." So how can a get an updated DDI? I appreciate any ideas. /Users/robertlawson/Desktop/Screenshot 2026-02-15 at 8.21.50 PM.png

Feedback Assistant: „This Feedback will no longer be monitored, and incoming messages will not be reviewed.“
Every now and then I get this very frustrating message on Feedback Assistant. For instance, in FB14696726 I reported an issue with the App Store Connect API. 4 weeks later, I got a reply, asking among other things for a „correlation key and Charles log“. I immediately replied saying that I didn‘t know what those are, and they replied After reviewing your feedback, it is unclear what the exact issue is. I pointed out that I had asked a question which was left unanswered, and they replied explaining what the correlation key is. Then I asked again what the Charles log is. They replied The Apple Developer website provides access to a range of videos covering various topics on using and developing with Apple technologies. You can find these videos on our Development Videos page: http://developer.apple.com/videos. I opened the link and searched for „Charles“ but there were no results, so I asked to kindly point me to the video answering my question. They replied 3 months later (today): Following up on our last message, we believe this issue is either resolved or not reproducible with the information provided and will now consider this report closed internally. This Feedback will no longer be monitored, and incoming messages will not be reviewed. This is not the first time I ask for clarification and get back a message basically telling me that „we won‘t answer any questions you may have and won‘t hear anything you still may have to say about this issue“. They didn‘t even ask me to verify if the issue is resolved or not, like they sometimes do. No, they just shut the door in my face. I just wanted to share this frustrating experience. Perhaps an Apple engineer wants to say something about it or a developer has had a similar experience?

Built in ssh-add doesn't read ~/.ssh/config
I'm trying to authenticate to a git host using SSH keys stored in 1Password. I have ~/.ssh/config with mode 600 set with a symlink: Host * IdentityAgent "~/.1password/agent.sock" But ssh-add -l shows no identities. If I set $SSH_AUTH_SOCK, ssh-add -l works just fine. I'd love to not have to do this, though. Why doesn't ssh-add seem to read ~/.ssh/config? The built-in version is OpenSSH_10.0p2, LibreSSL 3.3.6. I've searched fruitlessly for an answer anywhere else.

Apple 403 detected - Access forbidden
Im getting this specific error 'Apple 403 detected - Access forbidden' when trying to build my app, my previous 10 builds all succesfully work but now it keeps on giving this error. I'm guessing its because of a new agreement email I recieved. But when i got to both developer website and app store connect there is no new agreements to accept. I'm quite stuck. Any help appreciated. Thanks

memory leak in dlopen / dlcose, or user error?
Calling dlopen then dlclose causes an increase in the amount of memory used by the program. If I create a loop that calls dlopen / dlclose repeatedly on the same dynamic library, memory usage increases continuously. Is this a bug, or am I using dlopen / dlclose incorrectly? I can reproduce this by modifying the sample code in the Apple Developer docs Creating Dynamic Libraries. If I modify Runtime.c, changing the line void *lib_handle = dlopen(lib_name, RTLD_NOW); to add the infinite loop, as below: void *lib_handle = dlopen(lib_name, RTLD_NOW); for (int ii = 0; ; ++ii) { printf("loop %i\n", ii); int close_err = dlclose(lib_handle); printf("close error: %i\n", close_err); printf("dlopen(%s, RTLD_NOW)\n", lib_name); lib_handle = dlopen(lib_name, RTLD_NOW); } then opening and closing the dynamic library will succeed, but memory usage (as reported by top) will rapidly increase. I'm running on x86_64 macOS 13.6.6. Full code for the modified Runtime.c is attached, the rest of the code is available in the Apple Developer docs. Any suggestions? Many thanks, Chris Runtime.c

App Icon Dimension
I am trying to make an app icon 20 x 20 pixel dimension. I cannot get the icon to be sized this way. It gets blurry. I have used adobe express + illustrator. I have not been able to size it. It is a 400 x 400 dimension png. I want the proportion to be 20 x 20 without losing the clarity.

Alarmkit- custom sounds
Hello guys, I know people already talked about this here but maybe some of you solved it. When trying Alarmkit, it keeps playing the same default sound. I tried a lot of changes to make it play my custom sound but nothing worked. Has anyone solved this or is it just the alarmkit problem? Thank you and take care guys.

Document Type Export / Import in Xcode - Shared via Messages
I’ve created a document type for my app and set it up in the Info Configuration in Xcode. This all works as expected: Implemented with the Transferrable API and ShareLink, I can share an app’s file via the Files app or Notes and then import the file via a Share extension and the fileImport swiftUI api. My question is regarding Messages, specifically. It appears as a ShareLink option and I’m able to send my app’s document type via a message, but I’m unable to open it or share it (internally, with my app), other than being able to forward or delete it. If I copy the file, I can’t access it within my app (it’s still stored in the Messages private bundle) and startAccessingSecurityScopedResource returns false as expected. The message does detect the right icon, so it’s recognizing the custom document type. If my Share Extension, exported document type, and transferable implementation is configured correctly, should I be able to open a file for my app shared via Messages? Is this an allowed action? I get various answers from AI, and I can’t test this in the Simulator on pre-26 devices.

Authentication issue from Expo EAS CLI
Hello, I am experiencing an authentication issue when submitting my Expo iOS app to App Store Connect using the Expo EAS CLI from the terminal. The exact flow is as follows: I run the submit command in the terminal. I am prompted to enter my Apple ID. After entering the Apple ID, I am prompted to enter my Apple ID password. After the password is accepted, I am prompted to enter a 6-digit verification code. I receive the 6-digit code immediately via SMS or phone call. I enter the code correctly and immediately, but the CLI always returns “Invalid code.” This happens every time. Important notes: The Apple ID and password are correct. The 6-digit code is entered immediately and exactly as received. Logging in to App Store Connect via a web browser with the same Apple ID, password, and SMS code works without any issue. The problem only occurs when authenticating through the terminal using Expo EAS CLI. Could you please advise why the verification code is being rejected in the CLI and how I can successfully authenticate and submit my app?

Running tests on multiple simulators and local mock servers
Hello, I have a question about running tests on multiple simulators. Currently, my company has a WDIO+Appium test suite with XCUITEST driver that runs on a single simulator through a mockttp proxy (we are intercepting and mocking some of the responses from our APIs and pass through the rest). In order to route the traffic we are currently using 'networksetup -setsecurewebproxy '. Everything works as expected. With growing number of tests we'd like to scale number of simulators on a single host to 3-5. We have a working setup but the problem are system-wide proxy settings routing traffic from multiple simulators, which we can't distinguish by UDID or any other means, we know of. We can spin multiple mock servers on the same machine but we are struggling to find the way to route the traffic on a simulator basis. In the end, both options are viable: 1 mock server running for multiple simulators N number of mock servers for N number of simulators Has anyone had the same/similar problem? How to approach this? We are currently running on Sequoia OSX and platform version 18.6. Thanks!

Icon Composer showing werid images
Hey guys! I downloaded Apple’s Icon Composer to build my iOS 26 app icon. I exported my SVG from Illustrator (and verified it through Canva and the W3C validator). However, when I import it into Icon Composer, it looks really weird . There are these bubble-like artifacts appearing in the center. Here's my orignal svg icon file trace-logo.txt Any help will be appreciated! Best, Justin

"Application has not loaded accessibility" timeout followed by silent auto-recovery corrupts framework state on iOS 18
On iOS 18, when XCUITest encounters an "Application has not loaded accessibility" error after the 60 second timeout, it performs an undocumented auto-recovery ("Setting up automation session") instead of halting the test as documented. This leaves the XCUITest framework in a corrupted state, causing subsequent tests in the same session to fail with unexpected behavior. Expected Behavior (per Apple documentation): Any failure in the launch sequence will be reported as a test failure and the test will be halted at that point. Actual Behavior: XCUITest waits 60 seconds for accessibility to load Logs "Application has not loaded accessibility" error Instead of halting, performs "Setting up automation session" (auto-recovery) Test continues with corrupted framework state Subsequent tests in the same session fail with phantom element queries Steps Run XCUITest suite on a real iOS 18 device Have an app with moderately heavy initialization (e.g., synchronous network operations during bootstrap) Observe intermittent "accessibility not loaded" errors When error occurs, subsequent tests fail with unexpected behavior Test Logs Evidence First test (accessibility failure + recovery): t = 11.11s Wait for accessibility to load t = 71.14s Capturing diagnostic spindump t = 76.24s Assertion Failure: Application 'com.example.app' has not loaded accessibility t = 76.26s Setting up automation session ← Undocumented recovery t = 77.29s Tear Down Second test (corrupted state): t = 35.01s Tap "signin-button" t = 35.55s Waiting for "bannerButtonStackFirstItem" ← Query NOT in test code! t = 40.58s Assertion Failure: Failed to find element The second test executes element queries that do not exist in its source code, indicating leaked/corrupted state from the previous test's failed recovery. Note: The tearDown() method terminates the app but cannot reset the internal state of the XCUITest framework itself, so corruption persists across tests. We are observing this behavior consistently on iOS 18 real devices. We would like to know: Is this a known issue with XCUITest on iOS 18? Is anyone experiencing similar "accessibility not loaded" failures followed by auto-recovery? Is the "Setting up automation session" recovery behavior intentional or a bug? Is there a recommended workaround to prevent framework state corruption between tests?

Missing Content from my app
Hi there! I am not a coder, but I built an app in ADALO just for in-house use in my company, PetroImaging. The app looked the way I wanted it to in the preview mode in ADALO, but when my app was approved and ready for download in the app store, a lot of content was missing. Many buttons that linked to screens were just gone - even though they were there in the preview and the buttons are formatted correctly in adalo. How can I get my content that I need back on my app so the employees can being using it?

Issue while creating ipa in release mode
I have an MAUI based application build and ready for the distribution. The application is working perfectly in the debug environment on the simulator. So the app logic is working correctly as expected without any errors. But when a release build is created the application crashes on the simulator and physical device. I'm developing the application using .Net 10 framework with target device iOS 26. The Supported OS Platform is set to 15.0 in csproj file. Also have the entitlements. plist file set in the csproj. The IDe used is Visual Studio Code for Mac (MAC OS). The application uses MSAL for the login / authentication purpose (Microsoft.Identity.Client) and SQLite Database (Sqlite-net-pcl) Message: Kindly guide me to build the application correctly in release version and get the ipa file ready for the in house distribution that could be deployed correctly on the physical device with iOS 18 / 26.

Problem getting Expectation objects (AI slop)
This is from an Xcode generated file. var values: [String] = [] let exp = Expectation() let c = pub.filter { $0 != nil }.map { $0! }.sink( The second line gives an error: "'Expectation' cannot be constructed because it has no accessible initializers". My best guess that Expectation objects come from some other Apple Swift Testing function, but I don't know where.
