My framework has private Objective-C API that is only used within the framework. It should not be exposed in the public interface (so it shouldn't be imported in the umbrella header).
To expose this API to Swift that's within the framework only the documentation seems to indicate that this needs to be imported in the umbrella header?
Import Code Within a Framework Target
To use the Objective-C declarations in files in the same framework target as your Swift code, configure an umbrella header as follows:
1.Under Build Settings, in Packaging, make sure the Defines Module setting for the framework target is set to Yes.
2.In the umbrella header, import every Objective-C header you want to expose to Swift.
Swift sees every header you expose publicly in your umbrella header. The contents of the Objective-C files in that framework are automatically available from any Swift file within that framework target, with no import statements. Use classes and other declarations from your Objective-C code with the same Swift syntax you use for system classes.
I would imagine that there must be a way to do this?

Hello,
I have integrated LZMA2 compression into my iOS app, Hogs, and successfully implemented compression. However, when attempting to upload the app for TestFlight, I encountered an error:
"The app references non-public symbols in Payload/Hogs.app/Hogs: _lzma_code, _lzma_end."
These functions are part of the LZMA compression library (specifically LZMA2). Here's a detailed description of the issue:
What I Have Done:
LZMA2 Integration: I integrated LZMA2 compression into the app and created a wrapper around the LZMA functions (_lzma_code, _lzma_end) to prevent direct references.
App Build Configuration:
I ensured the LZMA2 library is linked correctly with the -lzma flag in the linker settings.
I wrapped the LZMA functions in custom functions (my_lzma_code, my_lzma_end) in an attempt to avoid using the non-public symbols directly.
Error Message:
During the app submission process, I received the following error:
"The app references non-public symbols in Payload/Hogs.app/Hogs: _lzma_code, _lzma_end."
Steps Taken to Resolve:
Checked if any LZMA functions were exposed incorrectly.
Ensured that all non-public symbols were properly encapsulated in a wrapper.
Verified linker settings to ensure the proper inclusion of the LZMA2 library.
Request:
Could anyone provide suggestions or best practices to resolve this issue and avoid references to non-public symbols? Should I use a different method for linking LZMA2 or encapsulating these symbols?
Thank You:
I appreciate your help in resolving this issue so I can move forward with submitting the app for TestFlight.

We would like to show a user-friendly message but can not.
Description:
When attempting to create a duplicate passkey using the ASAuthrorizationController in iOS, the Face ID authentication times out SDK does not return a timeout specific error. Instead, it directly returns an error stating that duplicate passkey cannot be created.
SDK to first handle the FaceID timeout case and provide a distinct timeout error so we can gracefully manage this scenario before the duplicate passkey validation occurs.
Steps to Reproduce:
Implement passkey creation flow using ASAuthorizationController.
Attempt to register a duplicate passkey (e.g., using the same user ID and challenge).
Let FaceID prompt timeout (do not interact with the authentication prompt).

Hi, I'm relatively new to iOS development and kindly ask for some feedback on a strategy to achieve this desired behavior in my app.
My Question:
What would be the best strategy for sound effect playback when an app is in the background with precise timing? Is this even possible?
Context:
I created a basic countdown timer app (targeting iOS 17 with Swift/SwiftUI.). Countdown sessions can last up to 30-60 mins. When the timer is started it progresses through a series of sub-intervals and plays a short sound for each one. I used AVAudioPlayer and everything works fine when the app is in the foreground. I'm considering switching to AVAudioEngine b/c precise timing is very important and the AIs tell me this would have better precision.
I'm already setting "App plays audio or streams audio/video using AirPlay" in my Plist, and have configured:
AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, options: .mixWithOthers)
Curiously, when testing on my iPhone 13 mini, sounds sometimes still play when the app is in the background, but not always.
What I've considered:
Background Tasks: Would they make any sense for this use-case? Seems like not if the allowed time is short & limited by the system.
Pre-scheduling all Sounds: Not sure this would even work and seems like a lot of memory would be needed (could be hundreds of intervals).
ActivityKit Alerts: works but with a ~50ms delay which is too long for my purposes.
Pre-Render all SFX to 1 large audio file: Seems like a lot of work and processing time and probably not worth it. I hope there's a better solution.
I'd really appreciate any feedback.
I'm primarily an AppleScript writer and only a novice programmer, using ChatGPT to help me with the legwork. It has helped me to write a functioning app that builds a menu structure based on the scripts I have in the Scripts directory used in the script menu and then runs the applescripts. When I distribute the app to my desktop and run it, the scripts that access other apps, like InDesign will cause it to launch, but not actually do anything. I included the ids for each app in the entitlements dictionary and have given the app full disk access in system settings, but it's not functioning as I'd expect.
I know there are apps like Alfred that allow you to run scripts from a keystroke, but I'm building this for others I work with so they can also access info about each script, what it does, and how to use it from the menu, as well as key commands to run them.
Not sure what else to say, but if this sounds like a simple fix to anyone, please let me know.
I am using CHCSVParser in objective-c to use the CSVString extension of the Array instance method.
When I installed a new app on iOS18.1.1, the correct value (@"Application,"abc,def"") was returned for both the first and second turns, but
when I installed a new app on iOS18.2, the correct value was returned for the first turn, but @"" was returned for the second turn.
Even when I debug with step into, I can enter the CSVString for the first turn, but I cannot enter it for the second turn and after. It's as if the instance method is not being generated.
There are in-app purchases between the first and second turns, but the view controllers that are called are also the same.
Is there any change between iOS18.1.1 and iOS18.2?

I'm working on a cross-platform C# application that converts HTML content to PDF. The goal is to render dynamic HTML pages (including CSS and JavaScript) as high-quality, printable PDF files. Additionally, I need to support features like adding headers/footers, securing PDFs with passwords, and controlling user permissions. While everything works well on Windows, I need some help rendering consistency and handling permissions on MacOS.
Hello together,
since Xcode Version > 15 the following error handling causes following error "Pattern of type 'DecodingError' cannot match 'Never'
func getSupportedCountries() async {
// fetch all documents from collection "seasons" from firestore
let queryCountries = try? await db.collection("countries").getDocuments()
if queryCountries != nil {
self.countries = (queryCountries!.documents.compactMap({ (queryDocumentSnapshot) -> Country? in
let result = Result { try? queryDocumentSnapshot.data(as: Country.self) }
switch result {
case .success(let country):
if let country = country {
// A country value was successfully initialized from the DocumentSnapshot
self.errorMessage = nil
return country
}
else {
// A nil value was successfully initialized from the DocumentSnapshot,
// or the DocumentSnapshot was nil
self.errorMessage = "Document doesn't exist."
return nil
}
case .failure(let error):
// A Country value could not be initialized from the DocumentSnapshot
switch error {
case DecodingError.typeMismatch(_, let context):
self.errorMessage = "\(error.localizedDescription): \(context.debugDescription)"
case DecodingError.valueNotFound(_, let context):
self.errorMessage = "\(error.localizedDescription): \(context.debugDescription)"
case DecodingError.keyNotFound(_, let context):
self.errorMessage = "\(error.localizedDescription): \(context.debugDescription)"
case DecodingError.dataCorrupted(let key):
self.errorMessage = "\(error.localizedDescription): \(key)"
default:
self.errorMessage = "Error decoding document: \(error.localizedDescription)"
}
return nil
}
}))
} else {
self.errorMessage = "No documents in 'countries' collection"
return
}
}
the interesting part of the code where XCODE shows an error is from "switch error" downwards.
Does anyone of you have an idea what's wrong?
Ay help appreciated !
Thx, Peter

Hi There,
I have a iOS App which has been published and purely managing data by SwiftData. I use following simple codes everywhere in Views:
...
@Query var items: [Item]
....
if let firstItem = items.first( where: {...}) {
...
Then I encountered crash at Query that _items.wrapperdValue has some errors.
Then I tried to split first(where...) into ordinary way:
let filteredItems = items.filter(...)
if let firstItem = filteredItems.first {
...
It runs OK.
Is it a bug in SwiftData in 18.2 or I missed some steps to facilitate SwiftData macros?
Hello, I have an issue with importing some .mp3 files into a swift playground project (in Xcode, not in the Playground app). They worked fine in the Xcode project, but for some reason playgrounds isn't able to find them. I imported them the exact same way as I did in the Xcode project.

SE-0411 Isolated default value expressions
link: SE-0411, commentary
SE-0412 Strict concurrency for global variables
link: SE-0412
introduces: nonisolated(unsafe)
notes: While this is a proposal about globals, the introduction of nonisolated(unsafe) applies to “any form of storage”.
SE-0414 Region based Isolation

introduces: #isolation, optional isolated parameters
notes: This is what makes it possible to iterate over an async stream in an isolated async function.
SE-0421 Generalize effect polymorphism for AsyncSequence and AsyncIteratorProtocol
link: SE-0421, commentary
notes: Previously AsyncSequence used an experimental mechanism to support throwing and non-throwing sequences. This moves it off that. Instead, it uses an extra Failure generic parameter and typed throws to achieve the same result. This allows it to finally support a primary associated type. Yay!
SE-0423 Dynamic actor isolation enforcement from non-strict-concurrency contexts
link: SE-0423, commentary
introduces: @preconcurrency conformance
notes: This adds a number of dynamic actor isolation checks (think assumeIsolated(…)) to close strict concurrency holes that arise when you interact with legacy code.
SE-0424 Custom isolation checking for SerialExecutor
link: SE-0424, commentary
introduces: checkIsolation()
notes: This extends the custom actor executors introduced in SE-0392 to support isolation checking.

availability: upcoming feature flag: GlobalActorIsolatedTypesUsability
notes: This loosen strict concurrency checking in a number of subtle ways.
Swift 6.1
Swift 6.1 has the following additions.
Vision: Improving the approachability of data-race safety
link: vision
SE-0442 Allow TaskGroup’s ChildTaskResult Type To Be Inferred
link: SE-0442, commentary
notes: This represents a small quality of life improvement for withTaskGroup(…) and withThrowingTaskGroup(…).
SE-0449 Allow nonisolated to prevent global actor inference
link: SE-0449, commentary
notes: This is a straightforward extension to the number of places you can apply nonisolated.
Swift 6.2
Xcode 26 beta has two new build settings:
Approachable Concurrency enables the following feature flags: DisableOutwardActorInference, GlobalActorIsolatedTypesUsability, InferIsolatedConformances, InferSendableFromCaptures, and NonisolatedNonsendingByDefault.
Default Actor Isolation controls SE-0466
Swift 6.2, still in beta, has the following additions.
SE-0371 Isolated synchronous deinit
link: SE-0371, commentary
introduces: isolated deinit
notes: Allows a deinitialiser to access non-sendable isolated state, lifting a restriction imposed by SE-0327.
SE-0457 Expose attosecond representation of Duration
link: SE-0457
introduces: attoseconds, init(attoseconds:)
SE-0461 Run nonisolated async functions on the caller’s actor by default
link: SE-0461
availability: upcoming feature flag: NonisolatedNonsendingByDefault
introduces: nonisolated(nonsending), @concurrent
notes: This represents a significant change to how Swift handles actor isolation by default, and introduces syntax to override that default.
SE-0462 Task Priority Escalation APIs
link: SE-0462
introduces: withTaskPriorityEscalationHandler(…)
notes: Code that uses structured concurrency benefits from priority boosts automatically. This proposal exposes APIs so that code using unstructured concurrency can do the same.
SE-0463 Import Objective-C completion handler parameters as @Sendable
link: SE-0463
notes: This is a welcome resolution to a source of much confusion.
SE-0466 Control default actor isolation inference
link: SE-0466, commentary
availability: not officially approved, but a de facto part of Swift 6.2
introduces: -default-isolation compiler flag
notes: This is a major component of the above-mentioned vision document.
SE-0468 Hashable conformance for Async(Throwing)Stream.Continuation
link: SE-0468
notes: This is an obvious benefit when you’re juggling a bunch of different async streams.
SE-0469 Task Naming
link: SE-0469
introduces: name, init(name:…)
SE-0470 Global-actor isolated conformances
link: SE-0470
availability: upcoming feature flag: InferIsolatedConformances

notes: This is particularly useful when you want to conform an @MainActor type to Equatable, Hashable, and so on.
SE-0471 Improved Custom SerialExecutor isolation checking for Concurrency Runtime
link: SE-0471
notes: This is a welcome extension to SE-0424.
SE-0472 Starting tasks synchronously from caller context
link: SE-0472
introduces: immediate[Detached](…), addImmediateTask[UnlessCancelled](…),
notes: This introduces the concept of an immediate task, one that initially uses the calling execution context. This is one of those things where, when you need it, you really need it. But it’s hard to summary when you might need it, so you’ll just have to read the proposal (-:
In Progress
The proposals in this section didn’t make Swift 6.2.
SE-0406 Backpressure support for AsyncStream
link: SE-0406
availability: returned for revision
notes: Currently AsyncStream has very limited buffering options. This was a proposal to improve that. This feature is still very much needed, but the outlook for this proposal is hazy. My best guess is that something like this will land first in the Swift Async Algorithms package. See this thread.
SE-NNNN Closure isolation control
link: SE-NNNN
introduces: @inheritsIsolation
availability: not yet approved
notes: This aims to bring the currently experimental @_inheritActorContext attribute into the language officially. It’s not clear how this will play out given the changes in SE-0461.

I'm encountering an issue where certain images are not displaying on some iOS devices, while the same code works perfectly on others. There’s no error or crash — just some images fail to load or display. I've confirmed the image URLs and formats are correct.
Has anyone faced a similar issue or could suggest what might be causing this inconsistent behavior?
Thanks in advance!

I have an xcode project which has both cpp and swift code. In one of my usecase I am passing primitive type variables from swift to cpp by reference( primitives types list here as per the new cpp-swift interop documentation)
swift code:
// primitive check code:Bool
var x : Bool = true
// When we are passing a variable as a Reference, we need to use explicitly use'&'
student.PassBoolAsReferenceType (&x) // interop call to cpp code
print (x)
Cpp code:
void
Student::PassBoolAsReferenceType(bool &pValue) noexcept
{
std::cout << pValue << std::endl;
pValue = false;
}
The above code fails during compilation with no clear error message "Command SwiftCompile failed with a nonzero exit code"
However, all the other primitive types that I tested worked for the above code like Int, Float, Double etc. Only the Bool interop fails. Can someone explain why is it not possible for bool? I m using the new interop introduced in swift 5.9.
Hi There,
I have been using my Mac Studio to complete some work in Python (which I normally do in Linux) and recently I got this error which has completely stopped all development as venvs will no longer work correctly:
WARNING: Ignoring invalid distribution ... (and then whichever apps are currently installed in the venv
This occurs for me on every install of any version of Python installed using any of the standard methods (installer). I've tried all the main points of advice on knowledgeable forums, but the difference between Python on Sequoia and Python on Linux is enough such that I am at an end of my debugging knowledge. I've even attempted to blast away any System Python changes with a recovery reinstall, but the problem persists. I've done almost exactly the same setup on my MacBook Air and it is fine ... but the Studio is now unavailable for Python development.
I know I have probably dropped the ball somewhere but can't see the error myself so, I'm wondering if I should just blast away everything on the machine and go through the process of doing a clean install. Asking the experts in MacOS here so I can avoid the pain of doing that!

This topic area is about the programming languages themselves, not about any specific API or tool. If you have an API question, go to the top level and look for a subtopic for that API. If you have a question about Apple developer tools, start in the Developer Tools & Services topic.
For Swift questions:
If your question is about the SwiftUI framework, start in UI Frameworks > SwiftUI.
If your question is specific to the Swift Playground app, ask over in Developer Tools & Services > Swift Playground
If you’re interested in the Swift open source effort — that includes the evolution of the language, the open source tools and libraries, and Swift on non-Apple platforms — check out Swift Forums
If your question is about the Swift language, that’s on topic for Programming Languages > Swift, but you might have more luck asking it in Swift Forums > Using Swift.

I have been recently getting the following error seemingly randomly, when an event handler of a SwiftUI view accesses a relationship of a SwiftData model the view holds a reference to. I haven't yet found a reliable way of reproducing it:
SwiftData/BackingData.swift:866: Fatal error: This model instance was invalidated
because its backing data could no longer be found the store.
PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(url: COREDATA_ID_URL),
implementation: SwiftData.PersistentIdentifierImplementation)
What could cause this error? Could you suggest me a workaround?
I am an SDK provider working with Swift Package Manager (SPM) to deliver libraries for iOS developers. My SDK currently uses SPM targets to modularize functionality. However, SPM enforces strict resource bundling, which prevents me from efficiently offering multiple targets—each with a different set of localization files—in a single package.
Current Limitation:
When multiple SPM targets share the same source and resource directory but require distinct sets of .lproj localization folders (for app size or client requirements), SPM raises “overlapping sources” errors. The only workaround is to manually split resource directories or have clients prune localizations post-build, which is inefficient and error-prone.
Feature Request:
Please consider adding native support in Swift Package Manager for:
Defining multiple targets within a single package that can process overlapping source/resource directories,
Each target specifying a distinct subset of localization resource files via the exclude or a new designated parameter,
Enabling efficient modular delivery of SDKs to clients needing different localization payloads, without redundant resource duplication or error-prone manual pruning.
Support for this feature would greatly ease SDK distribution, lower app sizes, and improve package maintainability for iOS and all Swift platforms.
❌ Could not find email_ai.py in the app bundle. Available files: []
The error above is what I’m encountering.
I’ve placed the referenced file both in the project directory and inside the app. However, every time I remove and reinsert the file into the folder within the app, it prompts me to designate the targets—I select all, but this doesn’t resolve the issue.
I’m unsure how to properly reference the file so that it is recognised and included in the bundle. Any guidance would be greatly appreciated.
this is my build phase:
#!/bin/sh
set -x # Prints each command before running it (for debugging)
pwd # Shows the current working directory
echo "$SRCROOT" # Shows what Xcode thinks is the project root
ls -l "$SRCROOT/EmailAssistant/EmailAssistant/PythonScripts" # Lists files in the script folder
export PYTHONPATH="/Users/caesar/.pyenv/versions/3.11.6/bin"
/Users/caesar/.pyenv/versions/3.11.6/bin/python3 "$SRCROOT/EmailAssistant/EmailAssistant/PythonScripts/email_ai.py"
echo "Script completed."
