So I ran a promo for my app that got me 30k downloads or so. The app was free for a day and so it got lots of "purchases". There were two errors from StoreKit2 that I can't explain (I'll detail the other one in another post)
This one:
StoreKit.StoreKitError.systemError(Error Domain=NSCocoaErrorDomain Code=4097 "connection to service with pid 19497 named com.apple.storekitd" UserInfo={NSDebugDescription=connection to service with pid 19497 named com.apple.storekitd}
There are various theories online that the display name of the purchase could be an issue.
Another was that this indicates that this indicates that a helper process has crashed.
Generally my guidance was to restart the device and that seemed to resolve it for most if not everyone. But not everyone reached out and it rained bad reviews and I was accused of a bait and switch and so on.
Is there any way to mitigate this? Any way to address it? It doesn't happen for everyone but it happens very frequently still.

Hi everyone,
I’m encountering a crash in my app and need help understanding what’s causing it and how to resolve it.
As stated in the crash report, the issue is caused by exceeding the system-wide per-process port limit. Can you tell me how to locate and identify why this is happening?
Below are the full report of the crash log:

Hello Team!
Recently we cleaned up profiles and renewed certificates under developer account, noticing profile expiration date showing invalid, it supposed to show certificate expiration date. Due to this I am not able to update or download profiles. Any one experienced this this? what would be the solution?.
Thanks,
Kumar.

When I'm inspecting a WKWebView in a simulator and the WKWebView loads a local URL with a port number, I've found that most features of Safari dev tools that worked in iOS 17 are broken in iOS 18. Here are the steps I'm taking:
Set up a WKWebView with isInspectable = true that loads a local URL, e.g. https://www.local.mydomain.com:3000
Install a self-signed SSL certificate on a simulator for www.local.mydomain.com
Run my app on the simulator
The WKWebView loads successfully
In Safari on my Mac, I can select the WKWebView and open dev tools to inspect it
If the simulator is on iOS 17, this works fine, no issues.
But if the simulator is on iOS 18, Safari dev tools are mostly broken. I can tell that there is a connection to the WKWebView because the Network tab logs the requests that I expect. But I cannot use any of the other dev tools features: Elements, Sources, Console, etc.
Has anyone else encountered this? Is there a workaround?

I'm trying to rewrite an old AppleScript mail rule that I used extensively as a Mail extension using the MailKit framework and I've run into an issue.
Previously, when developing the script, it was possible to debug it by selecting the message I wanted it applied to and choosing the Mail.app menu item "Message/Apply Rules"
This would re-execute my script and I could iterate over it as many times as I liked while developing.
I haven't found any great way of doing this for my extension with a MEMessageActionHandler. The closest I've found is to forward the message to myself and wait for it to come back in again over the internet, at which point the extension would get executed again. Needless to say, this makes debugging my MEMessageAction handler much slower.
I've tried a number of things in Mail.app to try and get it to re-execute my extension with a particular message without any luck. Does anyone know of a good process for debugging a MEMessageActionHandler that doesn't involve forwarding the message to myself over and over and waiting for it to come in each time?

Hi, my server in Melbourne Australia is getting weather forecasts from a few places around Australia. When I look at the daily timesteps that I get back, they might be something like this:
"days": [
{
"forecastStart": "2025-06-25T00:00:00Z",
"forecastEnd": "2025-06-26T00:00:00Z",
"daytimeForecast": {
"forecastStart": "2025-06-25T07:00:00Z",
"forecastEnd": "2025-06-25T19:00:00Z",
"overnightForecast": {
"forecastStart": "2025-06-25T19:00:00Z",
"forecastEnd": "2025-06-26T07:00:00Z",}
It doesn't matter where I ask for - Melbourne, Darwin, Perth, it always comes back the same.
The documentation says that daytimeForecast is 7 am to 7 pm local and overnightForecast is 7pm to 7 am local.
However, in a place like Perth 7-19Z is 3 pm to 3 am, not 7 pm to 7 am like advertised.
I can see that for any given date, there are 3 maximum temperature forecasts, a 24 hour max, a daytime max and an overnight max and they differ from each other.
Can anyone help me understand what's happening here?
And furthermore in the example above, the 24 hour forecasts that have, for example this:
"forecastStart": "2025-06-25T00:00:00Z" ... Can the 00:00:00Z be trusted literally? Or is it more the case that it's "2025-06-25" but the HMS got tacked on in a conversion?

I filed FB16715590 about this. I have a vague memory this might be related to some code to pretend to be case insensitive, but I can't find it now.
I am a developer on a project at work. I recently got a new laptop; however, since then I have been unable to build/deploy our application. I received a copy of the Developer ID Application certificate and Developer ID Installer certificate from a fellow developer. Note, everything works on their machine with these certificates.
I have gone through the steps documented here https://developer.apple.com/forums/thread/712005
When I run security find-identity -p codesigning, I have two certificates that show up. one for my User and one for the Developer ID Application that my colleague gave me. Both show up as matching and valid identities.
When I try to codesign "MyTrue", as documented in the link above, using "Apple Development" works; however, the "Developer ID Application" identity does not. I get a errSecInternalComponent error.
ahenderson@ahendersonmacbook [17:29:23] [~/Downloads]
-> % codesign -s "Apple Development" -f MyTrue -vvv
MyTrue: replacing existing signature
MyTrue: signed Mach-O universal (x86_64 arm64e) [MyTrue]
ahenderson@ahendersonmacbook [17:30:48] [~/Downloads]
-> % codesign -s "Developer ID Application" -f MyTrue -vvv
MyTrue: replacing existing signature
Warning: unable to build chain to self-signed root for signer "Developer ID Application: SRS Pharmacy Systems, Inc. ([REDACTED])"
MyTrue: errSecInternalComponent
I have downloaded all of the intermediate certificates from the apple PKI and have them installed under my keychain in login.
Having spent days on this, I am at the end of my rope.
Laptop Specs:
M3 Pro
36GB Ram
MacOS Sequoia 15.1
It is worth noting that my colleagues laptop is not running Sequoia. Not sure if that makes any difference or not.
It is also worth noting, that I can run the codesign manually with the Developer ID Application using sudo (I know I shouldn't do this, but I just wanted to see if that made any difference).
I have an Xcode project setup as follows:
3 static libraries
1 framework target, whose Mach-O type is set to Dynamic Library
main app target (iOS app)
The target dependencies are as follows:
In framework's build phase [Link with libraries], I have the 3 libs statically linked.
In the main app's build phase [Link with libraries], I have only the framework, which is dynamically linked.
As per my understanding:
The libs are statically linked to the framework. So, the framework binary would contain code from all the libs.
The framework is dynamically linked to the main app (iOS app in this case). So, the main app's binary only has a reference to the framework's binary, which would be loaded in the memory at runtime.
Assuming my understanding is correct, I'm stuck with the following problem:
All 3 libs build successfully
The framework builds successfully
The main app target doesn't build. The compilation is successful, but the build fails with linker errors.
Please let me know if I am doing something incorrectly, or if a configuration is missing. Below are more details:
The linker gives the following error:
Undefined symbols for architecture arm64:
"StringUtils.GetStr() -> Swift.String", referenced from:
dynamic_fw.AppDelegate.application(_: __C.UIApplication, didFinishLaunchingWithOptions: [__C.UIApplicationLaunchOptionsKey : Any]?) -> Swift.Bool in AppDelegate.o

And the command shown in the logs for linking phase is:

We are building a framework which will be used by other apps. Want to integrate crash reporting and diagnostics for our framework. Want to report crashes to our backend happening inside our framework only and ignore app level crashes. Is it possible to filter crashes like that ?
Visual Studio 2022 is attempting to use port 11000 instead of 62078, but the port on iOS 18.5 is not listening for VS's Hot Reloading. Is this allowable? If so, how?
Background:
We are developing an App for both Windows, Android and iOS.
Our process is that virtually every pull request must be tested by a tester before being pushed to the main branch.
Up until now, we have been distributing the 3 versions to our testers via Microsoft AppCenter. Unfortunately, AppCenter is stopping per 31 March 2025 and we are looking for an alternative method.
As the Play Store isn't really useful for us for distributing android apps (a test build can take a few hours before appearing according to their documentation), we may have to look into setting up our own distribution website for our apps.
As such I was wondering, rather then using Test Flight for iOS, to also distribute the iOS app via our own website to our testers as it would be easier for our testers to have everything together.
Even though our apps are build and signed using an "ad hoc" provisioning profile, it's still not possible to just install the .IPA files just by downloading it.
The actual question:
So my question is, how can I install our app to our testers from a website. Do I have to set the link as something specific?
Or has AppCenter been using a trick not available to us mere mortals?
To clarify: I am only asking for distributing to our testers using the ad hoc provisioning profile with the test devices registers at apple. I am NOT asking for distribution to end users, that goes via the App Store as usual.
I've been using the weather kit API for months now without issue, but all of a sudden API queries return the response {"reason": "EXPIRED"}. The code around this area hasn't changed since June and the credentials haven't changed. The JWT is refreshed frequently (well within expiration). Have looked at the generated JWT in jwt.io and Payload and Header details correct and jwt.io reports JWT as "signature verified".
Is the JWT a red herring and its something else?
Here's an example URL:

Would appreciate any insights you may have.

We are experiencing an issue where our app gets stuck during launch. The splash screen appears for some time, and then the app either becomes unresponsive or closes unexpectedly. However, there are no crash logs captured in Xcode or Firebase Crashlytics, indicating that the app is not crashing but rather being terminated. This issue is preventing affected users from properly launching the app.
Additionally, some users have reported occasional lag and slow performance when using the app. The issue occurs only for a specific subset of users and appears to be related to other Electronic Logging Device (ELD) apps running in the background. When these apps are active, our app struggles to launch and sometimes becomes unresponsive.
We suspect that this behavior could be related to system resource allocation, such as high memory consumption by background apps, which might be affecting our app's ability to launch correctly. However, we have been unable to reproduce the issue on our end despite multiple attempts.
Actions Performed During App Launch:
Firebase configuration
API requests, including:
Fetching account details
Registering the FCM token with the server
Asynchronous background requests to fetch POI details
Creating a local database and storing POI data in local storage
We would like guidance from Apple regarding potential causes and debugging strategies, especially in scenarios where the app does not produce crash logs but still fails to launch properly. Any insights into memory management, conflicts with background applications, or system resource constraints would be highly appreciated.
Steps to Reproduce:
Install and launch the app on an affected device.
Observe that the app gets stuck on the launch screen.
After some time, the app terminates unexpectedly.
Issue is inconsistent and occurs only for certain users.
Presence of other ELD apps running in the background appears to influence the issue.
Is anyone seeing flaky results when using parameterized test with pairs of (input, result) data?
I have several (5) tests for a given method. I create a zip sequence by zip([in1, in2, in3, in4, in5],[out1, out2, out3, out4, out5])
Sometimes, the test only runs 4 of the tests and fails to report a failure even though I deliberately place data that should cause a failure.
Sometimes, even though I only select one test to run, the test explorer goes crazy into a loop and I have to clear test results to get it to stop. Following a suggestion, I disabled running tests in parallel.
Xcode 16.2 / OSX 14.7 (Sonoma) / Mac mini M2 Pro
It uses the SwiftJWT library. When decoding JWT, I get the error "JWT verifier failed to verify the JWT String signature".
This occurs when building Release with Xcode16.
It does not occur on Debug builds or Xcode15.
Please tell me how to solve it

I am using two iPhone11 devices, having iOS v17.6.1 for automation testing using Seleniumv4.X-Appium v2.x.
Today I updated the mac to Sequoia15 version which updated the XCode to v16.
Just after this update, I could not able to run the previously running automation script. The console message is "org.openqa.selenium.SessionNotCreatedException:
Could not start a new session. Response code 500. Message: Unable to launch WebDriverAgent. Original error: xcodebuild failed with code 70. This usually indicates an issue with the local Xcode setup or WebDriverAgent project configuration or the driver-to-platform version mismatch."
Hi all,
I'm trying to add Spotlight support to a macOS app that handles custom virtual machine bundles with the .vpvm extension. I’ve followed the current documentation and used the modern CSImportExtension approach with a Spotlight Importer extension target.
Here’s what I’ve done:
App Info.plist:
Declared com.makeprog.vpvm as a UTI conforming to com.apple.package.
Registered it under UTExportedTypeDeclarations and CFBundleDocumentTypes.
Spotlight Importer Extension:
Added a new macOS target using the Spotlight Import Extension template.
Set the NSExtensionPointIdentifier to com.apple.spotlight.import.
Used CSSupportedContentTypes = com.makeprog.vpvm.
Implemented a minimal update(_ attributes:forFileAt:) method that sets displayName, title, and contentDescription.
Other steps:
Verified that the .appex is embedded under Contents/PlugIns/.
Confirmed it appears in mdimport -e output with correct UTI.
Used mdimport -m -d2 -t /path/to/file.vpvm, but I still get:
Imported '/path/to/file.vpvm' of type 'com.makeprog.vpvm' with no plugIn.
The extension is never invoked. I’ve also tried:
Ensuring the .vpvm file is a valid directory bundle.
Restarting Spotlight / rebuilding index.
Ensuring the app and extension are properly signed.
Tried installing the app in test virtual machine
Question:
Has anyone successfully used CSImportExtension for custom UTIs?
Is there something additional I need to do for the extension to be recognized and triggered?
Any advice or examples would be greatly appreciated!
Thanks in advance.
I am trying to fix a bug in my iOS app that is dependent upon date and time. Is there any way to set the actual time on the iOS Simulator to a specific date and time? I know that you can set one for the status bar, but that doesn't affect the actual date and time that is reported by the system to apps.
