My project has a base app which is manually signed, inside I have a FileProvider parent app and extension.
When things works elegantly in Xcode debug build when I run FP App. But, when I package it, the FileProvider can't mount, fails with a generic error on parent app
(Error Domain=NSFileProviderErrorDomain Code=-2001 "The application cannot be used right now." UserInfo={NSLocalizedDescription=The application cannot be used right now.}
Another generic error in FileProvider demon
fileproviderd(488) deny(1) file-read-data /Applications/XYZ.app/Contents/Resources/FileFP.app
How to solve this?

I am using Xcode 14.3 and when Issue that says "Could not find bundle inside /Library/Developer/CommandLineTools under scntool". I searched this up and tried reinstalling CommandLineTools, reinstalling xcode, and reseting xcode.
Here are screenshots of the issue: https://docs.google.com/document/d/1H6HsoZoJhISMo-5cXG-kN0hat6jftcujL1iYK2TRkeA/edit
And here is the code: https://github.com/EnderRobber101/Xcode
Is there a solution? Please inform me of the solution. Thank you for reading.
SecCopyErrorMessageString suggests that the return value should be called with CFRelease to release/free the object.
Though upon attempting to do so, XCode says "CFRelease is unavailable: Core Foundation objects are automatically memory managed".
I have verified with Instruments in XCode that the follow code increases in memory usage without bound, from ~3MB to 20MB+ over 100000 iterations.
public func simpleLeak(){
var secReq: SecRequirement?
let err = SecRequirementCreateWithString("blah" as CFString, SecCSFlags(rawValue: 0), &secReq)
guard err == errSecSuccess else {
var errorString = SecCopyErrorMessageString(err, nil)
print(errorString)
return
}
}
What's the proper usage of SecCopyErrorMessageString that doesn't leak memory in Swift?
Hi!
Xcode 14.3 on MacOS 13.3.1
I'm developing in iOS app targeting iOS 14.0 and higher. I've included 4 cocoa pods in my project and my code has compiled and run just fine.
When I started to try to build an archive to submit to the app store, things started falling apart.
Now nothing compiles for simulators and test devices and I end up with linking errors with undefined symbols. I've tried clean builds, pod updating, pod installing, explicitly importing the modules in my swift code. I'm ready to pull my hair out.
Undefined symbols for architecture arm64:
"OBJC_CLASS$_SFGeometryUtils", referenced from:
objc-class-ref in MGRS.o
ld: symbol(s) not found for architecture arm64
Any suggestions? Randomly I can get past this road block and then I run into:
cannot find type 'TIFFImage' in scope
var tiffImage: TIFFImage!
Then randomly back to unresolved symbols by linker.
Thanks,
Bobby
I need to install the GoogleSignIn for my iOS application, and I did so.
The issue is that the watchOS app inside the project stops working because of build failures that are caused by the GoogleSignIn package. I cannot figure how to fix it, because inside the project settings, that package appears in the list of Frameworks for the iOS target, and is not present into the list of Frameworks for the watchOS target, as you can see in the first image below.
Can someone please shed some light? I have an app that uses Core Data and CloudKit, up until the last version, I was able to sync data between devices but now after I added two new Entities for some reason it stopped syncing between devices.
Here is how I did the change:
Created a new Core Data container.
Added the new Entities and their Attributes
Tested the new Entities locally to be able to send the new schema to CloudKit.
Went to CloudKit and made sure that the new Entities and Attributes were reflected on the Developent database.
Deploy Schema Cahnges.
Went to the Production database to make sure the new schema was deployed; and it was, both databases look the same.
Testing:
Tested in the simulator and with a real device and everything syncs, even the new Entities.
If I download the app from the App Store on two different devices they do NOT sync.
Based on the procedure I'm describing above, is there any important step I may have missed when doing the migration?
I'm not sure if this is related to the syncing issue but after testing a few times, I no longer can turn the iCloud on, I get the following message when I try to turn iCloud Sync On.
CoreData: error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate resetAfterError:andKeepContainer:]: <NSCloudKitMirroringDelegate: 0x282c488c0> - resetting internal state after error: Error Domain=NSCocoaErrorDomain Code=134410 "CloudKit setup failed because there is another instance of this persistent store actively syncing with CloudKit in this process."

Any idea of what could be wrong and preventing the devices from syncing? Any idea or suggestion is welcome.
Thanks
Hi,
I'd like to upload audio samples to the OpenAI Whisper API or others that take m4a, mp3, and wav data. I capture from the microphone and perform some basic signal processing to try to filter out non-voice samples and am left with AVAudioPCMBuffer.
It seems there are two approaches:
Use AVAudioConverter to create AVAudioCompressedBuffer in MPEG-4 audio format. I've gotten this working (although I can't verify that the compressed data is valid because I'm unable to export a file with proper MPEG-4 headers).
Use AVAssetWriter, but this writes to disk, which strikes me as inefficient.
Neither of these readily produces a memory buffer with a .m4a file inside.
Am I missing some obvious way to do this? How do people upload compressed audio data to remote endpoints?
I've also explored just trying to create my own MPEG-4 compliant header but I was unable to produce a valid file.
Thanks,

We have a requirement where we want to keep user in the browser until he completes the onboarding. Is there any way to keep the user in browser even if app is installed.
Issue is once app will come in foreground and then we can manually check and open the same link in browser but in that case app will open and go back to browser will give a bad user experience.

I am using aws amplify and it returns all of its results into models and their type is something like List. But I would like them in standard swift arrays so I can use all the functionality like .first and such. How can this be done easily?
My error:
Cannot convert value of type 'List?' to expected argument type '[ResourceSubCategory]'
Thank you!
Hi I upgraded my Mac to test the new os and iOS 17. But I have problems with the weather kit on the app.
WeatherKit enabled as app service and capability there was no issue with the iOS 16.
What could be the problem?
import Foundation
import WeatherKit
class WeatherKitManager: ObservableObject {
@Published var weather: Weather?
@Published var isFetchingWeather = false
func getWeather(latitude: Double, longitude: Double) async {
do {
let receivedWeather = try await WeatherService.shared.weather(for: .init(latitude: latitude, longitude: longitude))
DispatchQueue.main.async {
self.weather = receivedWeather
}
} catch {
fatalError("\(error)")
}
}
var symbol: String {
weather?.currentWeather.symbolName ?? "xmark.app"
}
var temp: String {
if let temp = weather?.currentWeather.temperature.converted(to: .celsius) {
let formattedTemp = String(format: "%.1f", temp.value)
return "\(formattedTemp)°C"
} else {
return "Yükleniyor..."
}
}
}

Hi, I'm an iOS developer who found an issue with the regularExpression option in the range method of the string. The return value differs between iOS 17 beta 1 and iOS 16, even when using the same regex pattern and input.
Build with XCode14.2
// Regex pattern to check thousand amount pattern but comma is optional.
// 10000 => Correct
// 1000,0 => Incorrect
let regex = "^[+-]?[0-9]{1,3}(?:,?[0-9]{3})*$"
let rangeOf10000 = "10000".range(of: regex, options: .regularExpression)
let rangeOf100000 = "100000".range(of: regex, options: .regularExpression)
// in iOS 17.0 developer beta
// rangeOf10000 = nil
// rangeOf100000 = got an object normally.
// in iOS 16.2
// rangeOf10000 = got an object normally.
// rangeOf100000 = got an object normally.
I don't know if the defect in the range method or my missing something in the regex pattern such a long time, but I wonder why rangeOf10000 is nil in iOS 17 beta 1.
I cannot run my app, I get this error. I installed xcode 15 beta on my mac m2 pro, also I have macOS Sonoma (v14.0) installed. In previous code versions the code was able to run.

I have a Mac app, Notenik, written with AppKit, that dynamically generates an Edit view that is used to edit multiple fields for a Note. Sometimes, depending on a user's request, multiple NSTextViews end up appearing within the same parent view (a tab, if that matters). Lately I and some of my users have noticed that, when moving from one NSTextView to another (either by tabbing or by clicking), the cursor initially fails to appear. Once the user starts editing within the NSTextView, the cursor appears and acts normally. And this doesn't occur when moving from an ordinary text field to an NSTextView -- only when moving from one NSTextView to another. But it is troubling and confusing to users that the cursor initially disappears. I'm not sure exactly when this started happening, but it has not been happening for very long. Although I make frequent updates to the app, this section of code has had no recent changes, so I am at a loss to explain this behavior, or to correct it. Any help would be appreciated.
I have a Utility app that does not have a Dock icon and runs in the menu bar. On macOS Sonoma (14 DB 1) you cannot use anymore the workaround that we used on previous versions of the macOS, as you get a warning that you should use SettingsLink.
NSApp.sendAction(Selector(("showSettingsWindow:")), to: nil, from: nil)
But the issue is, that before I usually were calling as well NSApp.activate(ignoringOtherApps: true) to activate the app. As clicking on the MenuBar app icon does not do that.
The SettingsLink only opens the Settings Scene, but does not actually activates the app. I could not find a workaround how to do so. As I cannot inject my code in SettingsLink call.
Any ideas how I can activate my app when SettingsLink is called?
Hey all!
Updating older code & libraries to some of the new Swift 5.9 / iOS 17 changes. Running into a weird issue with Xcode 15. Whenever I try to add a local Swift package, Xcode immediately crashes with the following trace. Anyone else seeing something similar or have a workaround?

All demo code from Apple that I know lacks view models.
Every time model data is directly injected into the view and even modified from the view via the new @Bindable macro.
Is Apple not using ViewModels and therefore MVVM at all?
I understand it might not really be required for the small demos, but it would still be helpful to understand, e. g. how the new @Model, @Observable, @Binding fit into the MVVM model.
Why am I getting this error during code time in editor window of Xcode at every call to print function?
Use of 'print' refers to instance method rather than global function 'print(_:separator:terminator:)' in module 'Swift'
Hello!
I can't preview the SwiftUI views of watchOS target in Xcode 15 beta 1, when the containing iOS app has a SPM dependency. Reproducing steps:
Create a new watchOS app project (with a companion iOS app) in Xcode 15.
Both iOS and watchOS ContentView can be previewed at this step.
Add a Swift package to the iOS target (the package should be an iOS-specific package, not a watchOS one, for example, https://github.com/siteline/SwiftUI-Introspect)
After you add the static library to iOS target, the watchOS preview no longer work anymore.
If you check the error message, you can find the Xcode preview attempt to build the iOS package against watchOS SDK.
Hi,
My app hangs for about a second when I open the app when it's been in background phase. It doesn't hang every time, but it hangs randomly (like once in 10 times) when I open the app again. I am not able to reproduce what causes this hang.
Hang Detection provides hang logs (spindump) when hang occurs. It has something to do with MusicKit as logs mention it but I cannot understand what it is. Please help me understand these logs.
I am running iOS 17 beta 1 with MusicKit and ApplicationMusicPlayer.
