I am trying to add complication feature to my watchOS app. I need to add some keys to the Info.plist.
Project Navigator - no Info.plist file (as expected)
Target watchOS > Build Settings > Info.plist values.
I am unable to add a value. Hovering over a row does NOT show small '+' or '-' icons.
How do I edit the Info.plist?

Xcode 16.2 archive fails to compile XIB
Xcode Archive command fails most of the time while compiling an XIB which was created in older Xcode.
XIB was updated in Xcode 16.2 version also which did not fix this issue.
Archive from Xcode app works but Xcode build command fails and no reason shown by the command.
** ARCHIVE FAILED **
The following build commands failed:
CompileXIB /Users…/Resources/Nibs/<XIB_NAME>.xib
Xcode 16 seems to „forget“ a swift package within a subfolder of a root package after restart or shut-down.
I have the following project structure, which also resembles the directory structure on disc:
MyPackage
- Package.swift
- README.md
- Sources
- MyPackage
- Tests
- MyPackageTests
- Tools
- MyGenerator // <- after restart this folder is not visible in the Xcode project navigator
- Package.swift
- Sources
- main.swift
- Tests
MyGenerator is a standalone package which is used during development of MyPackage to generate source code files for MyPackage based on text file input. Essentially an executable target script which I can run within its folder with:
swift run MyGenerator someInputFile.txt
MyPackage does NOT use MyGenerator as a dependency, nor do I want this tool listed as a dependency in MyPackage Package.swift file.
Yet MyGenerator is part of the same Git repo, as it documents the changes to the tool on how to generate source code for MyPackage. Both packages are developed in tandem.
MyGenerator itself defines dependencies in its Package.swift file, which are unrelated to the functionality of MyPackage.
After restart of Xcode or even just a longer shut-down period the MyGenerator subfolder is not visible in the Xcode project navigator, the /Tools folder is empty. I have to manually add the sub package via Add files to "MyPackage" -> Move files to destination every time.
How can I solve that Xcode remembers the sub package unter /Tools?
Edit: I am using Xcode 16.2
After update to Xcode 16.3, any breakpoints stopped in simulator and device. The scheme is configured to Debug in Build Configurator.

We’re developing an iPad application that visualizes 2D and 3D building floor plans, including a mesh network of nodes that control lighting and climate. The node count ranges from 1,000 to 15,000.
We’re using SceneKit to dynamically render the floor plan and node mesh on an iPad 10th generation running iPadOS 18.3. While the core visualization works, we are experiencing significant performance degradation as the node count increases.
Specifically:
At 750–1,000 nodes, UI responsiveness noticeably declines.
At 2,000 nodes, navigating the floor plan becomes nearly unusable.
We attempted to optimize performance with a Geometric Pool algorithm, but the impact was minimal. Strangely, the same iPad handles 30,000+ 3D objects effortlessly when using Unity or Unreal Engine, raising the question of whether SceneKit may not be optimized for this scale.
Our questions:
Is SceneKit suitable for visualizing such large node counts, or are we hitting an inherent limitation of the framework?
Are there best practices or optimization techniques for SceneKit that we might be missing?
Should we consider a hybrid approach or fully transition to a different 3D engine for this use case?
We’ve attached a code sample below demonstrating the issue. Any insights, suggestions, or experiences would be greatly appreciated!
ContentView.swift
I used Swift Playground to develop application in Mac OS. Also using ZStack I used limited area in full page (using .frame(width: $, height: $)). However using command + R or clicking start button to see preview .app, while non resizing application my ZStack show as cutted. Please tell me how to set preview .app frame size as width, height... The buttom code is ContentView.swift code.
@main
struct ContentView: App {
init() {
MyFont.registerFonts()
}
// @StateObject private var audioPlayer = AudioPlayer()
var body: some Scene {
WindowGroup {
NavigationStack {
StartMenuView()
.frame(minWidth: 594, maxWidth: 594,
minHeight: 1142, maxHeight: 1142)
.preferredColorScheme(.dark) // Dark Mod
.statusBar(hidden: true) // Hidden Status Bar
.edgesIgnoringSafeArea(.all) // Ignoring Safe Area
}
}
.windowResizability(.contentSize)
}
}
Thank you for reading.

So I got charged the annual developer fee on December 2024, and then again this February 2025.
Worse, a few days after getting charged twice, I received an email from Apple saying my developer account subscription has been suspended due to failure in paying the annual fee.
I already submitted a support ticket to Apple, but I haven't gotten a response yet.
Is there something else I can do?
Would appreaciate any help.
Thanks!

Hi,
I am getting an error stating "Argument passed to call that takes no arguments". I want this Apple Watch App to measure and store RR Intervals from the PPG sensor on the Apple Watch for Heart Rate Variability calculations. Please help me fix this, I can't figure it out. Here is my code:
heartbeatQuery = HKHeartbeatSeriesQuery(predicate: predicate,
dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in
// Switch to main thread for UI updates
DispatchQueue.main.async {
if let error = error {
print("Heartbeat query error: (error.localizedDescription)")
self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)"
// Consider stopping the workout session if the query fails critically
// self.stopWorkoutSession()
return
}
if ended {
print("Heartbeat query indicates series ended.")
}
// Append valid RR intervals
if timeSinceLastBeat > 0 {
self.rrIntervals.append(timeSinceLastBeat)
self.beatCount += 1
}
} // End DispatchQueue.main.async
}) // End query data handler
// --- END OF PROBLEMATIC INITIALIZER ---
// Execute the query if it was created successfully
It recommends the fix as removing this part:
'(predicate: predicate,
dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in
// Switch to main thread for UI updates
DispatchQueue.main.async {
if let error = error {
print("Heartbeat query error: (error.localizedDescription)")
self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)"
// Consider stopping the workout session if the query fails critically
// self.stopWorkoutSession()
return
}
if ended {
print("Heartbeat query indicates series ended.")
}
// Append valid RR intervals
if timeSinceLastBeat > 0 {
self.rrIntervals.append(timeSinceLastBeat)
self.beatCount += 1
}
} // End DispatchQueue.main.async
})'
But after I remove that it says "Cannot assign value of type 'HKHeartbeatSeriesQuery.Type' to type 'HKHeartbeatSeriesQuery'" PLEASE HELP ME
Thanks

Hi,
Our organisation just ran out of the included Xcode Cloud hours. I now want to upgrade (I am the account holder).
There does not seem to be a way to do this on the Apple Developer and/or App Store Connect websites, as you'd expect.
The Get started with Xcode Cloud page mentions that I need to use the Apple Developer app.
However, when I sign up to this in the Apple Developer app, the account shown when pressing Subscribe is my personal account, not any account related to the organization:
It is impossible to change the payment details.
How can I use the organization account to pay for this, as I obviously do not want to get charged to my personal account?
Thanks.

I work at a well-established university with a business journal that is over 25 years old. We have been waiting now for almost four months to have our Apple News account reviewed. In what world is this OK? No ability to communicate with anyone or have any updates except to log in once a month to see the 'under review' message still there. Seriously?
I'm experiencing an issue with a custom font not loading properly in Xcode 16.3. The font files are included in the bundle, listed in Info.plist, and verified for correct names using UIFont.familyNames, but they still don't appear at runtime. Has anyone else run into this with Xcode 16.3? Could this be related to recent changes in asset packaging or font catalogs?
Hey everyone,
I’ve been trying to get my apple developer account approved for weeks now with so many back and forth messages exchanged. However, I’m still not sure where my application stands.
I submitted my verification docs multiple times through a special link. It was under review but then no one acknowledged its current status. Later, I received a follow up asking me to enrol again because it was causing some issue. But when I tried doing that, it says there is some error And asked me to contact support to resolve this.
how long will this take before I get to the stage where I can make a payment and have my account approved?

I'm currently transferring an iOS app to a new Apple Developer account and following the process outlined in Apple’s documentation:
🔗 TN3159 - Migrating Sign in with Apple users for an app transfer
The process for generating transfer_identifiers and migrating existing users is clear, and I don’t expect issues with that part.
However, I have a question about preserving the user session after the transfer.
My setup:
The app uses Sign in with Apple via a backend-based authentication flow.
On login, the app retrieves the authorization_code and sends it to the backend.
The backend exchanges the code for tokens from Apple, including a refresh_token.
That refresh_token is then used on the backend to validate the user’s identity on subsequent requests.
My concern:
Once I initiate the app transfer, migrate users, and update the backend with new Apple credentials (client ID, team ID, etc.), I assume that the existing tokens issued under the old credentials will become invalid.
So my question is:
Is there a way to maintain the user’s authenticated session through this transition without requiring them to manually sign in again?
I’d like to ensure a seamless experience for users, if possible.

Hi,
You're here because your project has issues related to Xcode Previews or Swift Previews. The issue you're experiencing may be the result of any of the following:
An error in your SwiftUI app, Xcode previews, or on-device previews.
A configuration error in your Xcode project, including any third-party dependencies or packages.
A system issue in the operating system, SwiftUI, or in Xcode Previews.
Based on your request, I need more information about your SwiftUI app when rendering Xcode Previews or on-device previews. Specifically, I’ll need the diagnostics Swift Previews generates to make sure I understand the error encountered by the preview system. Please create a report in Feedback Assistant to share the details requested in the instructions below.
For issues with macOS, Mac Catalyst, on-device iOS, or on-device visionOS previews, perform the following steps to gather diagnostics:
Download and install the Swift Previews logging profile for your device.
Reproduce the error while previewing on device, taking note of the timestamp when the error occurred.
Attach the Previews diagnostics, sysdiagnose from your Mac, a sysdiagnose from the previewing iOS or visionOS device.
For issues with Xcode Previews, perform the following steps to gather diagnostics:
Download and install the Swift Previews logging profile for your device.
Reproduce the error in Xcode Previews, if you haven’t already done so.
If an error banner appears in the canvas, click the "Diagnostics" button within the banner, then go to Step 5; otherwise, continue to Step 4.
If the error banner is missing, navigate to the menu in Xcode: Editor > Canvas > Diagnostics
In the presented sheet, click the "Generate Report" button.
Attach a zip file containing the diagnostic report to your bug report (it will be named something like previews-diagnostics-0123456789.zip).
Submitting your feedback
Before you submit to Feedback Assistant, please confirm the following information is included in your feedback:
with the Swift Previews logging profile installed, attach the sysdiagnose logs gathered after reproducing the issue
the Previews diagnostics generated by Xcode
timestamp identifying when the issue was reproduced
focused sample Xcode project that reproduces the issue (if applicable)
screenshots or videos of the error (optional)
Please include all requested information to prevent delays in my investigation.
After your submission to Feedback Assistant is complete, please respond to your original Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your SwiftUI app, a configuration issue within your Xcode project, or an underlying issue in the operating system, SwiftUI, in Xcode Previews, or on-device previews.

I have an iOS app, and I am trying to add a companion WatchOS app. My iOS app depends on 2 libraries:
GoogleMobileAds
FirebaseAnalyticsWithoutAdIdSupport
When I add a new target for WatchOS, the preview build starts to fail. I am not adding any libraries to WatchOS. The Google Ads and Firebase Analytics libs are only under the iOS target.
I am unable to run the preview, I get an error when trying to build the watch scheme. The preview does not work. The build just crashes. I've included the error log below.
But, here are the steps I've tried so far:
Delete folders inside Derived Data
Run a clean build (Cmd + Option + Shift + K)
Delete scheme and create a new one
Reset Package Cache
Restart Xcode
Restart Macbook
But, it just does not work. I do not understand why the watchOS target is erroring for "GoogleUserMessagingPlatform" and "GoogleMobileAdsTarget" when those packages are not linked/used for the watchOS.
SchemeBuildError: Failed to build the scheme “timerWatch Watch App”

Hey folks,
We are looking for a way to increase the sampling frequency beyong what's currently called "high frequency sampling" for CPU profiler (or time profiler -- doesn't really matter for us).
We are aware that this is not offered through the UI but wondering if we can somehow experimentally enable this via the .tracetemplate (plist).
Basically, we see that samplingRate exists (in the plist) but don't see it having an effect on the actual runs. The resulting trace file always lists sample-rate-micro-seconds="1000" for the data table. E.g.,
<table trigger="time" pmc-events="Cycles" target-pid="SINGLE" schema="counters-profile" needs-kernel-callstack="0" sample-rate-micro-seconds="1000"/>
Cheers

I have a swift project with a Watch companion.
Since the update of Xcode in 16.3 version after updating MAcOs , Watch OS, iOS to the latest version . It is quasi impossible for me to make Xcode work with my series 10 Watch. I have a lot of alert box, messages in the "device & Simulator" tool like this
Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters.
And many message telling me that Xcode is preparing the Watch , then that it has lost the connexion.
I have to wait some minutes after EACH run of the App to test it again. This is very annoying .
Some of the alerts I have :
And the best to know , is that I can run the APP outside of Xcode , it works, Connects to the iPhone, fetch data and so. the iPhone sees the Watch without and problem.
Reboots can solve for a few minutes the problem. But that is not a solution.

My newly registered Apple Developer account has been unexpectedly blocked before I was able to submit our app. This is our first iOS app and I believe this may be a misunderstanding. We’d like to resolve this as quickly as possible (case ID is 102568035119). Please let us know the steps we need to take.
