This is a bit of a headscratcher. Xcode 16 fyi.
I've written a standalone watchos app (with a stub ios app).
Distributes and works perfectly over Testflight.
I've submitted for app store and it passed the checks an I've released it for sale.
Told my brother to use a promo code to download it and show me how it looks and report me any nuisances.
He tells me there's no app neither on phone (expected) nor in watch. And he checked both the Watch ios app list and the watch.
I've gone through various GPTs and they've all told me the basic troubleshooting. That his watch might not be supported (wrong, it's a watch 10 ultra with latest updates and my min supported versions are hilariously low).
They've suggested that I might not have the right keys for making it standalone set, also no. They suggested that skip_install shouldn't be set to no; also wrong I think they're thinking xcode 13 and below. The stub ios app has a dependency on watchos app and also has an embed directive. I also checked the archive and saw the watchos app embedded indeed.
Again, the app works perfectly fine when distributed over testflight. And AFAIK that's a release build which I know for a fact because I had a problem with not giving healthkit entitlements to release (that was another but minor headscratcher at the time, when it was working over direct xcode upload).
Minor detail, I've written, test(flight)ed the app in UK and in English, my brother is in Turkey.
Of course now I immediately pulled the app out of sale because I don't want people paying and getting nothing, that's gonna cause a lot of trouble.
So I need any help I can get to
How to debug this without exposing the app and myself: is it possible to limit the release?
Obviously: what could be going wrong?
How the hell did I even pass app review? Is this maybe isolated to my brother's watch?
I'm more than happy to share project files and/or info.plist files(end products of them, because my plists are generated from project file).

Hello!
I’m trying to handle custom URLs (e.g., customurl://open?param=value) that open the app. However, while the app launches via the custom URL as expected, the parameters are not being passed to or are accessible from the iOS-specific implementation.
Currently, if I open a custom URL via Safari, the app gets launched but the custom URL and parameters are not accessible.
customurl://open?hello=test
According to the iOS Docs ( https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app#Handle-incoming-URLs )
any URLs should be passed to:
func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:] ) -> Bool
I do not register the above application function to be called but instead this one is executed during app start with launchOptions always being nil:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool
This is the case regardless of if the App is started fresh or was already running in the background.
My pInfo entry for the custom URL:
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleTypeRole</key>
<string>Viewer</string>
<key>CFBundleURLName</key>
<string>dev.customurl.project</string>
<key>CFBundleURLSchemes</key>
<array>
<string>customurl</string>
</array>
</dict>
<dict/>
</array>
TLDR: How can I access the parameters, passed with the URL?
Any thoughts on what I am doing wrong?
On my MAC, I have a XPC server running as a daemon. It also checks the clients for codesigning requirements.
I have multiple clients(2 or more).
Each of these clients periodically(say 5 seconds) poll the XPC server to ask for a particular data.
I want to understand how the performance of my MAC will be affected when multiple XPC clients keep polling a XPC server.
Is it possible to change the title "Choose Activites" and also remove the search on the FamilyActivityPicker?
We are planning to use our internal IdP (PingFederate) for authentication of end users in their iOS apps using ASWebAuthenticationSession. Initial tests are successful, but the user is prompted for every login (and logouts) with a consent dialogue box:
“AppName” wants to use “internal domain-name” to Sign In
This allows the app and website to share information about you.
Cancel Continue”
Let’s say that our top-level domain is “company.no”, where our IdP is placed at “idp.company.com”. I have seen examples where the Associated domains entitlement points to the idp as a webserver for serving the JSON output AASA file. In this case that would be:
authsrv: idp.company.com
Anyone with experience implementing this structure with the IdP as webserver for serving the JSON output?
Our problem is that trying to use the IdP as webserver for this purpose is that it is very complicated to modify the IdP’s webserver configuration. Also, this modification needs to be re-done every time we need to upgrade the IdP.
My question is therefore also related to the options of which webserver to install the AASA file on. Has anyone installed the file on a generic webserver on the toplevel domain like
“webserver.company.com” ?
I'm just trying to display an image that is stored in the local filesystem, but the more I dig into this the more confused I get.
So previously I used this code (it's simplified):
func findImage(name: String) -> UIImage? {
do {
let url = try FileManager.default.url(for: .applicationSupportDirectory,
in: .userDomainMask,
appropriateFor: nil,
create: false)
.appendingPathComponent("MyFolder")
.appendingPathComponent("\(name).png")
guard let image = UIImage(contentsOfFile: url.path) else {
return nil
}
return image
} catch {
print(error.localizedDescription)
}
return nil
}
Notice I create the URL with just .appendingPathComponent() and turning URL to path via url.path.
It works! So what's the question?
In Improving performance and stability when accessing the file system I've read that you better use the new appendingPathComponent(_:isDirectory:), that's good, will do.
Also url.path is deprecated in iOS18. Should I use url.path(percentEncoded:) instead? What should be the value of percentEncoded when accessing the local filesystem?
In this adjacent thread I've read:
Don't use UIImage(contentsOfFile:) either, because it's a path-based API. There's no URL-based equivalent, which is an Apple clue that should be doing something else.
Is this true? Then how should I store and load my images?
Just FYI, I create images like this:
private func generateThumbnail(name: String) {
guard let drawingWidth = canvasGeo?.size.width,
let drawingHeight = canvasGeo?.size.height else { return }
let thumbnailRect = CGRect(x: 0, y: 0, width: drawingWidth, height: drawingHeight)
Task {
UITraitCollection(userInterfaceStyle: .light).performAsCurrent {
let image = self.canvasView.drawing.image(from: thumbnailRect, scale: UIScreen.main.scale)
guard let data = image.pngData() else { return } // -- HERE
do {
try FileManager.default.createDirectory(at: try FileManager.default.url(for: .applicationSupportDirectory,
in: .userDomainMask,
appropriateFor: nil,
create: true)
.appendingPathComponent("MyFolder"),
withIntermediateDirectories: true,
attributes: nil)
let filename = "\(name).png"
let url = try FileManager.default.url(for: .applicationSupportDirectory,
in: .userDomainMask,
appropriateFor: nil,
create: true)
.appendingPathComponent("MyFolder")
.appendingPathComponent(filename)
try data.write(to: url, options: .atomic) // -- and HERE
} catch {
print(error.localizedDescription)
}
}
}
}
My usecase — just save the user's PencilKit Canvas as an image and display it back to him on a different View. I'm on SwiftUI and iOS 16+.
Would be happy to learn the correct way, thanks!
In iOS 18 (beta 1-4) when you set openAppWhenRun = false in your AppIntent of your live activity the perform function never gets called.
In iOS 16 and 17 my live activities work. I have downloaded other apps and in their live activities any button tab which doesn´t open the app is also doing nothing in iOS 18.
Has anyone got this working? Any comments from an Apple engineer on this?
I have universal links configured for my iOS app which work as expected when the app is installed. When the app is not installed the universal link will go to the browser as expected.
What I want to do is redirect to the app store, allow the user to install the app, then redirect them to the initial universal link. Redirecting them to the app store isn't the hard part I can achieve that from the webpage, however I don't know how to save a reference to that initial link to redirect them once they instal the app.
What I want the flow to be for a user who doesn't have the app is:
visit a universal link (example.com/UUID)
redirect to the app store and install the app
open the app and redirect to example.com/UUID
I've seen some ways people are doing this with the clipboard but I don't love that solution, I also don't want to use a 3rd party service if I can avoid it - how are the 3rd party services making this happen?
In my app, I implemented a screen recording functionality.
But there was an unexpected crash.

We observed a new crash after upgrading to iOS 18.
This crash does not occur on iOS 17 or earlier.
Crash Stacks From Xcode Organizer

Crash Stacks From APM
After the app is put in background for sometime and brought in to foreground and the app crashes each time with a different thread stack entries but all of them states same exception reason.
The documentation specifies that when Contacts framework returns unified contacts that each fetched unified contact object (CNContact) has its own unique identifier that’s different from any individual contact’s identifier in the set of linked contacts and that when refetching a unified contact, that this identifier should be used.
There is also an analogous identifier within the list of contactRelations, but each of these don't seem to corespondent to the unified contacts. For example, is a new contact (Sheryl Zakroff) is created in the simulator Contacts and their spouse is set to Hank Zakroff. However, the GUID created for the contactRelations identifier does not correlate to the original Hank Zakroff GUID and cannot be searched.
Is this a bug or what is the indent of the contactRelations identifier?
Here's a debug output of walking the unifiedContacts:

In my Catalyst app I use
func setupMailComposer() {
// Check if the device can send email
guard MFMailComposeViewController.canSendMail() else {
print("Mail services are not available")
showMailErrorAlert()
return
}
// Create and configure the mail composer
let mailComposeVC = MFMailComposeViewController()
mailComposeVC.mailComposeDelegate = self
// Set the email details
mailComposeVC.setToRecipients(["example@example.com"])
mailComposeVC.setSubject("Subject for your email")
mailComposeVC.setMessageBody("This is the body of the email.", isHTML: false)
// Attach a file (optional)
if let filePath = Bundle.main.path(forResource: "example", ofType: "pdf"),
let fileData = try? Data(contentsOf: URL(fileURLWithPath: filePath)) {
mailComposeVC.addAttachmentData(fileData, mimeType: "application/pdf", fileName: "example.pdf")
}
// Present the mail composer
self.present(mailComposeVC, animated: true, completion: nil)
}
Since I have updated to macOS 15.1 the canSendMail() function returns false although I have configured Apple Mail (like before in 15.0 where it worked flawlessly).
Hello,
After being in the AppStore for more than a year with the app working perfectly, yesterday I started seeing that WeatherKit requests failed with
Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"
Encountered an error when fetching weather data subset; location=<+41.40217108,+2.20023642> +/- 0.00m (speed -1.00 mps / course -1.00) @ 13/12/25, 12:20:35 Central European Standard Time, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"
I checked on developer.apple.com and we still have everything turned on and
No changes were made from an already deployed app; and we pay 200$ a month for WeatherKit, this is unacceptable since it's not the first time WeatherKit randomly decides to stop working.
More fun facts: the widget works fine...
I have an app developed by using the Callkit/Call-Blocking and received feedback from individual users, when using [cxcalldirectorymanager reloadextensionwithidentifier] to write call blocking data, it returned error code 11 with the following contents:
errorCode: 11
errorDomain: com.apple.callkit.database.sqlite
errorDescription: sqlite3_step for query 'DELETE FROM PhoneNumberBlockingEntry WHERE extension_id =?' returned 11 (11) errorMessage 'database disk image is malformed'
I want to know the reasons for this error and how to solve it,Thanks!
How do I handle force quit in Swift? I received crash reports during a tesflight test. I didn't understand what it was: none of my app's symbols were present, and Xcode didn't want them either... unlike two others who were very specific.
By doing a few Google queries, I saw that [UIApplication _terminateWithStatus:] + 136 (UIApplication.m:7578). Accompanied by a SIGSEV... corresponded to a simple thing: it's a crash during a force quit.
I tested it with two iPhones, connected to my Mac, and launched the app from Xcode on each of them. I waited a bit, then quit it. It immediately went into the background and waited to launch operations with BackgroundTaskManager. I went to the app carousel and quit it with a swipe of my finger. I immediately see in the log that "sceneDidDisconnect" from SceneDelegate is called... then the immediate crash occurs, with the same elements as those received during the test flight
crashlog.crash
: SIGSEV and [UIApplication _terminateWithStatus:] and identical elements thereafter.
And this applies regardless of what I put in "SceneDidDisconnect," a print, and something to close the BGtasks if they are running (but iOS should normally kill them too, right?) .. 1 or 2 secondes after it crashes.
At the moment of the crash, the Xcode cursor is positioned on "class Appdelegate" in AppDelegate.
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
My question is: how do I handle force quit in Swift? I have another Objective-C application that does the same thing and runs identical operations in the background. If I force quit it, there is no crash.

Dear Apple Support Team,
I hope this message finds you well.
I’m reaching out to inquire about the limitations of deferred deep linking within iOS applications. Specifically, I’m interested in understanding the constraints and challenges that prevent deferred deep links from functioning as expected in certain scenarios (e.g., when the app is not installed or other related issues).
Additionally, I would like to ask if there are any recommended alternative approaches or solutions to implement deep linking, ensuring that users can still be directed to specific content or screens even if they need to install the app first.
Your insights and guidance would be greatly appreciated as I work to enhance the user experience in my app.
Thank you for your time and assistance.
Best regards,
Santosh
Hi
I'm novice developer.
I’m currently developing a phone number blocking app using a Call Directory Handler Extension.
The blocking feature works perfectly on iOS 18.5, but it doesn’t seem to function properly on iOS 26 beta 4.
The extension is invoked, and the numbers are passed correctly, but incoming calls are not being blocked as expected.
Is there a known issue with CallKit or Call Directory Extensions on iOS 26 beta 4
Hello,
I have a question about data deserialization using NSKeyedUnarchiver in iOS SDK development.
Current Situation:
Previously, we were using the NSKeyedUnarchiver.unarchiveObject(with: Data) function
We have changed to using the NSKeyedUnarchiver.unarchivedObject(ofClasses:from:) method to deserialize complex objects stored in UserDefaults
We need to include all types in the ofClasses parameter, including Swift primitive types as well as various custom classes and structs within the project
Questions:
Implementation Approach: Is it correct pattern to include all classes defined in the project in the ofClasses array? Is this approach recommended?
Runtime Stability: When using this approach, is there a possibility of runtime crashes? Are there any performance issues?
Alternative Methods: If the current approach is not the correct pattern, what alternatives should we consider?
Current Code Structure:
All model classes conform to the NSSecureCoding protocol
We use the requiringSecureCoding: true parameter
We use a whitelist approach, explicitly listing only allowed classes
I would like to know if this structure is appropriate, or if we should consider a different approach.
Thank you.
