Hey everyone,
I’m developing an app for visionOS where I need to display the Apple Vision Pro’s current IP address. For this I’m using the following code, which works for iOS, macOS, and visionOS in the simulator. Only on a real Apple Vision Pro it’s unable to extract an IP. Could it be that visionOS currently doesn’t allow this? Have any of you had the same experience and found a workaround?
var address: String = "no ip"
var ifaddr: UnsafeMutablePointer<ifaddrs>? = nil
if getifaddrs(&ifaddr) == 0 {
var ptr = ifaddr
while ptr != nil {
defer { ptr = ptr?.pointee.ifa_next }
let interface = ptr?.pointee
let addrFamily = interface?.ifa_addr.pointee.sa_family
if addrFamily == UInt8(AF_INET) {
if let name: Optional<String> = String(cString: (interface?.ifa_name)!), name == "en0" {
var hostname = [CChar](repeating: 0, count: Int(NI_MAXHOST))
getnameinfo(interface?.ifa_addr, socklen_t((interface?.ifa_addr.pointee.sa_len)!), &hostname, socklen_t(hostname.count), nil, socklen_t(0), NI_NUMERICHOST)
address = String(cString: hostname)
}
}
}
freeifaddrs(ifaddr)
}
return address
}
Thanks in advance for any insights or tips!
Best Regards,
David

I'm building a SwiftUI app using SwiftData. In my app I have a Customer model with an optional codable structure Contact. Below is a simplified version of my model:
@Model class Customer {
var name: String = ""
var contact: Contact?
init(name: String, contact: Contact? = nil) {
self.name = name
self.contact = contact
}
struct Contact: Codable, Equatable {
var phone: String
var email: String
var allowSMS: Bool
}
}
I'm trying to query all the Customers that have a contact with @Query. For example:
@Query(filter: #Predicate<Customer> { customer in
customer.contact != nil
}) var customers: [Customer]
However no matter how I set the predicate I always get an error:
BugDemo crashed due to an uncaught exception NSInvalidArgumentException. Reason: keypath contact not found in entity Customer.
How can I fix this so that I'm able to filter by contact not nil in my Model?
I’m an amateur developer working on a free utility for composers/producers, for which the macOS release needs to create and name RTP-MIDI sessions in Audio MIDI Setup from the command line (so I can ship a small C helper instead of telling users to click through the UI). Here’s what I’ve tried so far, without luck:
• Plist hacks: Injecting entries into ~/Library/Audio/MIDI Configurations/*.mcfg works when AMS is closed, but AMS immediately locks and reverts my changes when it’s open.
• CoreMIDI C API: I can create virtual ports with MIDISourceCreate, but attempting MIDIObjectGetDataProperty on the apple.midirtp.session plugin always returns err –10836.
• Obj-C & Swift: Loading MIDINetworkSession and calling defaultSession, init, setNetworkName: and setting enabled = YES doesn’t produce a new session object in the Network panel.
• dlopen/dlsym: I extracted the real CoreMIDI binary out of the dyld shared cache and tried binding _MIDINetworkSessionCreate, _SetName, _SetEnabled, etc., but all the symbols come back null or my tool segfaults.
• Plugin registration: I’ve pulled the factory UUID (70C9C5EA-7C65-11D8-B317-000393A34B5A) from /System/Library/Extensions/AppleMIDIRTPDriver.plugin/Contents/Info.plist and called CFPlugInRegisterFactories, but it still never exposes the session-creation calls.
At this point I’m convinced I’m either loading the wrong binary or missing one critical step in registering the RTP-MIDI plugin’s private API. Can anyone point me to:
The exact path of the dylib or bundle that actually exports the MIDINetworkSessionCreate/MIDINetworkSessionSetName/MIDINetworkSessionSetEnabled symbols?
A minimal working snippet (C or Obj-C) that reliably creates and names a Network-MIDI session?
Any pointers, sample code, or even ideas about where Apple hides this functionality on macOS 15 would be hugely appreciated. Thanks!
Hello everyone, I think I've discovered a bug in JSONDecoder and I'd like to get a quick sanity-check on this, as well as hopefully some ideas to work around the issue.
When attempting to decode a Decodable struct from JSON using JSONDecoder, the decoder throws an error when it encounters a dictionary that is keyed by an enum and somehow seems to think that the enum is an Array<Any>.
Here's a minimal reproducible example:
let jsonString = """
{
"variations": {
"plural": "tests",
"singular": "test"
}
}
"""
struct Json: Codable {
let variations: [VariationKind: String]
}
enum VariationKind: String, Codable, Hashable {
case plural = "plural"
case singular = "singular"
}
and then the actual decoding:
let json = try JSONDecoder().decode(
Json.self,
from: jsonString.data(using: .utf8)!
)
print(json)
The expected result would of course be the following:
Json(
variations: [
VariationKind.plural: "tests",
VariationKind.singular: "test"
]
)
But the actual result is an error:
Swift.DecodingError.typeMismatch(
Swift.Array<Any>,
Swift.DecodingError.Context(
codingPath: [
CodingKeys(stringValue: "variations", intValue: nil)
],
debugDescription: "Expected to decode Array<Any> but found a dictionary instead.",
underlyingError: nil
)
)
So basically, the JSONDecoder tries to decode Swift.Array<Any> but encounters a dictionary (duh), and I have no idea why this is happening. There are literally no arrays anywhere, neither in the actual JSON string, nor in any of the Codable structs.
Curiously, if I change the dictionary from [VariationKind: String] to [String: String], everything works perfectly.
So something about the enum seems to cause confusion in JSONDecoder. I've tried to fix this by implementing Decodable myself for VariationKind and using a singleValueContainer, but that causes exactly the same error.
Am I crazy, or is that a bug?
I'm trying to disable the sleep timer when a button is pressed in my macOS app but the problem is that from the resources I've seen elsewhere the code doesn't work.
The code I'm trying is
UIApplication.shared.isIdleTimerDisabled = true
When I try and run my app I get this error
Cannot find 'UIApplication' in scope
From what I've managed to search for regarding this it appears that UIApplication might be an iOS thing, but how can I adapt this for macOS? I've found some code samples from 5+ years ago but it involves lots of code. Surely, in 2025 macOS can disable sleep mode as easy as iOS, right?
How can I achieve this please?
Hi,
I’m trying to use the new InlineArray type, but noticed that it is unfortunately only available on macOS 26 and not on macOS 15 and others. As this is quite an essential type, I was wondering if this is intended or will this change in later beta’s? Not having it available on older Darwin platforms would severily limit it’s usage in the coming years.
Thanks!
I am sort of trying to do the opposite of what others are doing. I have a target called CopyFramework that creates a CopyFramework.framework within my main xcproj file.
I set up this target because a specific framework (we can call it Tools.xcframework) is distributed as a binary. That framework file lives within the code.
Tools.xcframework is structured like so
Tools.xcframework (Coding/testBuild/DynamicToolFrameworks/Tools.xcframework)
info.plist
ios-arm64/
Tools.xcframework/
Tools (executable file)
Tools.bundle
Headers/
Info.plist
Modules/
Tools.swiftmodule/
arm64-apple-ios.abi.json
arm64-apple-ios.private.swiftinterface
arm64-apple-ios.swiftdoc
arm64-apple-ios.swiftinterface
module.modulemap
module.private.modulemap
PrivateHeaders/
ios-arm64_x86_64-simulator/
When the CopyFramework target is run xcode does a few steps which copy the correct version of this framework to derived data.
Process Tools.xcframework (iOS)
Coding/testBuild/DynamicToolFrameworks/Tools.xcframework
/Library/Developer/Xcode/DerivedData/testBuild-sha/Build/Products/Debug-iphoneos/Tools.framework ios
cd /Users/calebkierum/Coding/testBuild
builtin-process-xcframework --xcframework Coding/testBuild/DynamicToolFrameworks/Tools.xcframework --platform ios --target-path Library/Developer/Xcode/DerivedData/testBuild-sha/Build/Products/Debug-iphoneos
Meaning essentially that the Tools.xcframework for the proper platform is taken from Tools.xcframework/ios-arm64 and copied to Library/Developer/Xcode/DerivedData/testBuild-sha/Build/Products/Debug-iphoneos/Tools.xcframework
I am writing a Swift Package that needs to be able to reference the correct Tools.xcframework. I have set it up like so:
let package = Package(
name: "CoreObjC",
platforms: [.iOS(.v17), .macCatalyst(.v17)],
products: [
.library(name: "CoreObjC", targets: ["CoreObjC"]),
],
dependencies: [
// Does something to here ???
//.package(path: "../testBuild")
],
targets: [
.target(
name: "CoreObjC",
dependencies: [
// Here I would like to be referencing the CopyFramework.framework target within my buildTest.xcproj file
.product(name: "CopyFramework", package: /*??? its not in a swift package its a part of an xcproj file*/)
],
path: "CoreObjC",
publicHeadersPath: "Headers",
linkerSettings: [
.linkedFramework("Tools", .when(platforms: [.iOS])),
.linkedLibrary("c++")
]
),
],
cxxLanguageStandard: CXXLanguageStandard.gnucxx14
)
Now obviously this does not work. I do not know how to communicate to the Package.swift file that the binary dependency is a framework target within my xcproj file. If I do run the target CopyFramework followed by building CoreObjC it works though (so long as you comment out the bits trying to reference CopyFramework). Running the CopyFramework target processes the Tools.xcframework and copies the proper xcframework sub folder to Derived data and the Swift Package build system seems to be able to see it.
Is there a way I can get rid of this manual step? Make it so that when I build the CoreObjC target (swift package) that either CopyFramework is run or some other process is run to get the proper xcframework out of Coding/testBuild/DynamicToolFrameworks/Tools.xcframework and into DerivedData?
Is it even theoretically possible to have a Swift Package reference a target in a normal xcproj file?
When you apply an animation to a custom Transition in Swift 6, it is likely that that the app will crash with a SwiftUI.AsyncRenderer dispatch_assert_queue_fail error. Non-animated Transitions do not crash nor do animated system transitions. If you use ViewModifiers to create an AnyTransition with the .modifier(active:, identity:) static method, there is no problem.
I used the example Transition in the docs for Transition to illustrate this problem.
I'm using Xcode 16.2 RC and Swift 6, running iOS 18.1.1 on an iPhone 16 Pro.
I've created two separate Previews that illustrate what specifically crashes the app and what doesn't as well as a workaround for this bug.

PLATFORM AND VERSION
Development environment: Xcode 16.4 (16F6), macOS 15.5 (24F74)
Run-time configuration: iOS 18.3.1
DESCRIPTION OF PROBLEM
I cannot build my app due to a module not found error when I'm importing Sample-Swift.h header to an ObjectiveC file.
I need to use Swift code to ObjectiveC file with Swift code using an external XCFramework.
It seems to be related to a mix with ObjectiveC and Swift code when Swift code uses class inheritance from FZWorkoutKit class.
With a full Swift project, no issue.
STEPS TO REPRODUCE
Project https://fizzup.s3.amazonaws.com/files/public/Sample-WK.zip
Open the provided project and try to build it. The issue occurs.
In MyObject.m file, if you comment the first import (Sample-Swift.h), no issue occurs but I cannot use my Swift code (MyFile class).
Uncomment the line commented in step 1.
Go to MyFile.swift and change class inheritance from GoModeController (from FZWorkoutKit framework) to UIView (from UIKit). No issue occurs.
I have developed a Swift macro called @CodableInit in the SwiftCodableMacro module, and I’m able to use it successfully in my main project.
Here’s an example usage:
import SwiftCodableMacro
@CodableInit // This is for Codable macros
public class ErrorMonitoringWebPlugin {
public var identifier: UUID = UUID()
// MARK: - Codable
required public init(from decoder:Decoder) throws {
let values = try decoder.container(keyedBy: CodingKeys.self)
identifier = try values.decode(UUID.self, forKey: .identifier)
}
}
However, when I try to write a unit test for the ErrorMonitoringWebPlugin class, I encounter an issue. Here's the test case:
func testCodableSubjectIdentifierShouldEqualDecodedSubjectIdentifier() {
self.measure {
let encoder = JSONEncoder()
let data = try? encoder.encode(subject)
//Here I am getting this error
Class 'JSONEncoder' requires that 'ErrorMonitoringWebPlugin' conform to 'Encodable'
let decoder = JSONDecoder()
let decodedSubject = try? decoder.decode(ErrorMonitoringWebPlugin.self, from: data!)
XCTAssertEqual(subject.identifier, decodedSubject?.identifier)
}
}
The compiler throws an error saying:
Class 'JSONEncoder' requires that 'ErrorMonitoringWebPlugin' conform to 'Encodable'
Even though the @CodableInit macro is supposed to generate conformance, it seems that this macro-generated code is not visible or active inside the test target.
How can I ensure that the @CodableInit macro (from SwiftCodableMacro) is correctly applied and recognized within the XCTest target of my main project?
If try to dynamically load WhipserKit's models, as in below, the download never occurs. No error or anything. And at the same time I can still get to the huggingface.co hosting site without any headaches, so it's not a blocking issue.
let config = WhisperKitConfig(
model: "openai_whisper-large-v3",
modelRepo: "argmaxinc/whisperkit-coreml"
)
So I have to default to the tiny model as seen below.
I have tried so many ways, using ChatGPT and others, to build the models on my Mac, but too many failures, because I have never dealt with builds like that before.
Are there any hosting sites that have the models (small, medium, large) already built where I can download them and just bundle them into my project? Wasted quite a large amount of time trying to get this done.
import Foundation
import WhisperKit
@MainActor
class WhisperLoader: ObservableObject {
var pipe: WhisperKit?
init() {
Task {
await self.initializeWhisper()
}
}
private func initializeWhisper() async {
do {
Logging.shared.logLevel = .debug
Logging.shared.loggingCallback = { message in
print("[WhisperKit] \(message)")
}
let pipe = try await WhisperKit() // defaults to "tiny"
self.pipe = pipe
print("initialized. Model state: \(pipe.modelState)")
guard let audioURL = Bundle.main.url(forResource: "44pf", withExtension: "wav") else {
fatalError("not in bundle")
}
let result = try await pipe.transcribe(audioPath: audioURL.path)
print("result: \(result)")
} catch {
print("Error: \(error)")
}
}
}
Is there a way to detect when your apps (or any app I guess) is being moved by the user clicking and dragging the main window around the desktop at all?
I'm trying to find out if there's a way I can find out if a window is being clicked and dragged and whether there's certain triggers to the movement a little bit like shaking an iPhone with Shake to Undo.
Thanks
Hi,
Anybody knows will this occurs when using navigationStack at iOS 18.3? The navigationStack not stay at safeareas
the code as simple as that:
NavigationStack(path: $navManager.path) {
VStack {
Text("Hello")
}
.navigationDestination(for: Route.self) { route in
switch route {
....
}
}
}
.environmentObject(navManager)
.environment(logic)
I am trying to save to cloud kit shared database. The shared database does not allow zones to be set up.
How do I save to sharedCloudDatabase without a zone?
private func addItem(recordType: String, name: String) {
let record = CKRecord(recordType: recordType)
record[Constances.field.name] = name as CKRecordValue
record[Constances.field.done] = false as CKRecordValue
record[Constances.field.priority] = 0 as CKRecordValue
CKContainer.default().sharedCloudDatabase.save(record) { [weak self] returnRecord, error in
if let error = error {
print("Error saving record: \(record[Constances.field.name] as? String ?? "No Name"): \n \(error)")
return
}
}
}
The following error message prints out:
Error saving record: Milk:

Hey everyone,
I have a problem with an app im creating. The code doesn't have any errors but the console has this that pops up:
Snapshot request 0x1054191d0 complete with error: <NSError: 0x10541a970; domain: FBSSceneSnapshotErrorDomain; code: 4; "an unrelated condition or state was not satisfied"> {
NSLocalizedDescription = an error occurred during a scene snapshotting operation;
}
I'm running into a seemingly unsolvable compile problem with the new Xcode 26 and Swift 6.2.
Here's the issue.
I've got this code that was working before:
NSAnimationContext.runAnimationGroup({(context) -> Void in
context.duration = animated ? 0.5 : 0
clipView.animator().setBoundsOrigin(p)
}, completionHandler: {
self.endIgnoreFrameChangeEvents()
})
It's very simple. The clipView is a scrollView.contentView, and "animated" is a bool, and p is an NSPoint
It captures those things, scrolls the clip view (animating if needed) to the point, and then calls a method in self to signal that the animation has completed.
I'm getting this error:
Call to main actor-isolated instance method 'endIgnoreFrameChangeEvents()' in a synchronous nonisolated context
So, I don't understand why so many of my callbacks are getting this error now, when they worked before, but it is easy to solve. There's also an async variation of runAnimationGroup. So let's use that instead:
Task {
await NSAnimationContext.runAnimationGroup({(context) -> Void in
context.duration = animated ? 0.5 : 0
clipView.animator().setBoundsOrigin(p)
})
self.endIgnoreFrameChangeEvents()
}
So, when I do this, then I get a new error. Now it doesn't like the first enclosure. Which it was perfectly happy with before.
Here's the error:
Sending value of non-Sendable type '(NSAnimationContext) -> Void' risks causing data races
Here are the various overloaded definitions of runAnimationGroup:
open class func runAnimationGroup(_ changes: (NSAnimationContext) -> Void, completionHandler: (@Sendable () -> Void)? = nil)
@available(macOS 10.7, *)
open class func runAnimationGroup(_ changes: (NSAnimationContext) -> Void) async
@available(macOS 10.12, *)
open class func runAnimationGroup(_ changes: (NSAnimationContext) -> Void)
The middle one is the one that I'm trying to use. The closure in this overload isn't marked sendable. But, lets try making it sendable now to appease the compiler, since that seems to be what the error is asking for:
Task {
await NSAnimationContext.runAnimationGroup({ @Sendable (context) -> Void in
context.duration = animated ? 0.5 : 0
clipView.animator().setBoundsOrigin(p)
})
self.endIgnoreFrameChangeEvents()
}
So now I get errors in the closure itself. There are 2 errors, only one of which is easy to get rid of.
Call to main actor-isolated instance method 'animator()' in a synchronous nonisolated context
Call to main actor-isolated instance method 'setBoundsOrigin' in a synchronous nonisolated context
So I can get rid of that first error by capturing clipView.animator() outside of the closure and capturing the animator. But the second error, calling setBoundsOrigin(p) - I can't move that outside of the closure, because that is the thing I am animating! Further, any property you're going to me animating in runAnimationGroup is going to be isolated to the main actor.
So now my code looks like this, and I'm stuck with this last error I can't eliminate:
let animator = clipView.animator()
Task {
await NSAnimationContext.runAnimationGroup({ @Sendable (context) -> Void in
context.duration = animated ? 0.5 : 0
animator.setBoundsOrigin(p)
})
self.endIgnoreFrameChangeEvents()
}
Call to main actor-isolated instance method 'setBoundsOrigin' in a synchronous nonisolated context
There's something that I am not understanding here that has changed about how it is treating closures. This whole thing is running synchronously on the main thread anyway, isn't it? It's being called from a MainActor context in one of my NSViews. I would expect the closure in runAnimationGroup would need to be isolated to the main actor, anyway, since any animatable property is going to be marked MainActor.
How do I accomplish what I am trying to do here?
One last note: There were some new settings introduced at WWDC that supposedly make this stuff simpler - "Approchable Concurrency". In this example, I didn't have that turned on. Turning it on and setting the default to MainActor does not seem to have solved this problem.
(All it does is cause hundreds of new concurrency errors in other parts of my code that weren't there before!)
This is the last new error in my code (without those settings), but I can't see any way around this one. It's basically the same error as the others I was getting (in the callback closures), except with those I could eliminate the closures by changing APIs.
Hello,
I am developing a private internal Flutter app for our customer, which will not be published on the Apple Store. One of the key features of this app is to collect RF strength metrics to share user experience with the network.
For Android, we successfully implemented the required functionality and are able to collect the following metrics:
Signal strength level (0-4)
Signal strength in dBm
RSSI
RSRQ
Cell ID
Location Area Code
Carrier name
Mobile country code
Mobile network code
Radio access technology
Connection status
Duplex mode
However, for iOS, we are facing challenges with CoreTelephony, which is not returning the necessary data. We are aware that CoreTelephony is deprecated and are looking for alternatives.
We noticed that a lot of the information we need is available via FTMInternal-4. Is there a way to access this data for a private app? Are there any other recommended approaches or frameworks that can be used to gather cellular network information on iOS for an app that won't be distributed via the Apple Store?
my swift code
import Foundation
import CoreTelephony
class RfSignalStrengthImpl: RfSignalStrengthApi {
func getCellularSignalStrength(completion: @escaping (Result<CellularSignalStrength, Error>) -> Void) {
let networkInfo = CTTelephonyNetworkInfo()
guard let carrier = networkInfo.serviceSubscriberCellularProviders?.values.first else {
completion(.failure(NSError(domain: "com.xxxx.yyyy", code: 0, userInfo: [NSLocalizedDescriptionKey: "Carrier not found"])))
return
}
let carrierName = carrier.carrierName ?? "Unknown"
let mobileCountryCode = carrier.mobileCountryCode ?? "Unknown"
let mobileNetworkCode = carrier.mobileNetworkCode ?? "Unknown"
let radioAccessTechnology = networkInfo.serviceCurrentRadioAccessTechnology?.values.first ?? "Unknown"
var connectionStatus = "Unknown"
...
...
}
Thank you for your assistance.
Basically when showing a view using the .fullScreenCover modifier, it has no background anymore, any other UI elements are still shown but the view under it is also still shown.
Feedback id: FB16140301
Below are the steps to reproduce the bug in Contacts app.
Open Contacts app.
Now search for a contact and didSelect that contact.
Now slightly hold swipe right(from view's center leading position) as to pop the view but not fully swipe, now release the finger and you can see the back nav bar button missing and tapping the back button position also doesn't perform dismiss action.
Now do fully swipe from left to right to dismiss(pop) current view.
Here you can see the search bar missing.-> That's the bug.
The project builds successfully but unable to archive project on Xcode 26.
