I am making application where I use navigation link to navigate from bottom menu to other views, and there is a problem when I change view a few times because views start stacking and when I set navigationBarBackButtonHidden(false) I can see on left side a lot of back button. This generate big problem because after changing views I got warning Abnormal number of gesture recognizer dependencies: 100. System performance may be affected. Please investigate reducing gesture recognizers and/or their dependencies. And after some more changes everything from screen is pushed down back button. Is there any solution to close previous view from we came?
There is code:

I have
var idleScanTimer = DispatchSource.makeTimerSource()
as a class ivar. When the object is started, I have
self.idleScanTimer.schedule(deadline: .now(), repeating: Double(5.0*60))
(and it sets an event handler, that checks some times.)
When the object is stopped, it calls self.idleScanTimer.cancel().
At some point, the object containing it is deallocated, and ... sometimes, I think, not always, it crashes:

I tried changing it to an optional and having the deinit call .cancel() and set it to nil, but it still crashes.
I can't figure out how to get it deallocated in a small, standalone test program.

I am using the simulator to launch my app and can see AppDelegate related logs but I am not seeing any SceneDelegate logs (I suppose because it is not being initialized nor called).
I have tried restarting the computer/Xcode, clean and rebuild the application but none of the things I tested work.
Is there any part of my code wrong? Any other idea here?
Hi everyone, I attempted to use the MultivariateLinearRegressor from the Create ML Components framework to fit some multi-dimensional data linearly (4 dimensions in my example). I aim to obtain multi-dimensional output points (2 points in my example). However, when I fit the model with my training data and test it, it appears that only the first element of my training data is used for training, regardless of whether I use CreateMLComponents.AnnotatedBatch or [CreateMLComponents.AnnotatedFeature, CoreML.MLShapedArray>] as input.
let sourceMatrix: [[Double]] = [
[0,0.1,0.2,0.3],
[0.5,0.2,0.6,0.2]
]
let referenceMatrix: [[Double]] = [
[0.2,0.7],
[0.9,0.1]
]
Here is a test code to test the function (ios 18.0 beta, Xcode 16.0 beta)
In this example I train the model to learn 2 multidimensional points (4 dimensions) and here are the results of the predictions:
▿ 2 elements
▿ 0 : AnnotatedPrediction<MLShapedArray<Double>, MLShapedArray<Double>>
▿ prediction : 0.20000000298023224 0.699999988079071
▿ _storage : <StandardStorage<Double>: 0x600002ad8270>
▿ annotation : 0.2 0.7
▿ _storage : <StandardStorage<Double>: 0x600002b30600>
▿ 1 : AnnotatedPrediction<MLShapedArray<Double>, MLShapedArray<Double>>
▿ prediction : 0.23158159852027893 0.9509953260421753
▿ _storage : <StandardStorage<Double>: 0x600002ad8c90>
▿ annotation : 0.9 0.1
▿ _storage : <StandardStorage<Double>: 0x600002b55f20>
0.23158159852027893 0.9509953260421753 is totally random and should be far more closer to [0.9,0.1].

Hello.
I want to do a fetch when a view loads. In UIKit I would have used viewDidLoad to do this but in SwiftUI we only have onAppear and task. Is that by design, and if so, what is the recommended way to fetch data?
I wrote a little blog post for a workaround describing the issue and the found solution, but I presume there is a better way.

Usage of multiple async lets crashes the app in a nondeterministic fashion. We are experiencing this crash in production, but it is rare.

We managed to isolate the issue, and we submitted a technical incident (Case-ID: 8007727). However, we were completely ignored, and referred to the developer forums.
To reproduce the bug you need to run the code on a physical device and under instruments (we used swift concurrency). This bug is present on iOS 17 and 18, Xcode 15.1, 15.4 and 16 beta, swift 5 and 6, including strict concurrency.
Here's the code for Swift 6 / Xcode 16 / strict concurrency:

async let last = getLastName()
async let age = getAge()
async let role = getRole()
return try await Person(firstName: first,
lastName: last,
age: age,
familyMemberRole: role)
}
private func getFirstName() async throws -> String {
try await Task.sleep(nanoseconds: 1_000_000_000)
return ["John", "Kate", "Alex"].randomElement()!
}
private func getLastName() async throws -> String {
try await Task.sleep(nanoseconds: 1_400_000_000)
return ["Kowalski", "McMurphy", "Grimm"].randomElement()!
}
private func getAge() async throws -> Int {
try await Task.sleep(nanoseconds: 2_100_000_000)
return [56, 24, 11].randomElement()!
}

We are trying to access and copy some files [e.g., video file] from another PC on local network using SMB protocol.
We found some third party libraries like AMSMB2 for this.
But we want to try to use Apple inbuilt features like File management mentioned in - https://developer.apple.com/videos/play/wwdc2019/719/
We could able to select file from SMB server using document picker in app manually. Also we got its url in debug which gets generated under "Shared" section in files app.
The URL I get from document picker is -> /private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/asd0QUsers/testuser/iOS/SMB_ShareFolder
Now we want to avoid manual selection of file to user.We want directly open "/private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/asd0QUsers/testuser/iOS/SMB_ShareFolder" path as soon as document picker opens. So that user can directly select file. But it is not working. It opens normal files app and all folders.
Getting below error -
Access Shared URL directly using documentPicker "Error - CFURLResourceIsReachable failed because it was passed a URL which has no scheme"
Sharing the code which I tried to open this shared folder directly :
let url = URL (string: "/private/var/mobile/Library/LiveFiles/com.apple.filesystems.smbclientd/asd0QUsers/Pranjali/iOS/SMB_ShareFolder")
let documentPicker = UIDocumentPickerViewController(forOpeningContentTypes: [UTType.folder])
documentPicker.delegate = self
documentPicker.allowsMultipleSelection = false
documentPicker.modalPresentationStyle = .custom
documentPicker.definesPresentationContext = true
documentPicker.directoryURL = url!
documentPicker.transitioningDelegate = customTransitioningDelegate
present(documentPicker, animated: true, completion: nil)
I get error in console - CFURLResourceIsReachable failed because it was passed a URL which has no scheme 2024-07-05 17:49:38.501059+0530 VideoImportPOC[1327:336989] [DocumentManager] revealDocumentAtURL encountered an error: Error Domain=NSCocoaErrorDomain Code=262 "The file couldn’t be opened because the specified URL type isn’t supported."
Can you please provide inputs if it is possible to access files directly in this way? or any other suggestions.
I have been working on an app, and am really happy with the designs on iPhones 15-11, however every time I use the iPhone SE, the designs look terrible and everything overlaps (yes even with restraints and stack views and what not.)
I want to know could I make a seperate version of my app for every iPhone (that isn't the se) and a special dedicated version for SE users? If this isn't possible, can I just block SE users from the app?
Hello, Developer team! Does anyone have an idea about the problem I'm facing with the simulator ? I'm learning how to code in SwiftUI and my simulator was working just fine but yesterday I close my laptop the other day and open today and see the code :
import SwiftUI
import SwiftData
@main
struct first_projectApp: App {
var sharedModelContainer: ModelContainer = {
let schema = Schema([
Item.self,
])
let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false)
do {
return try ModelContainer(for: schema, configurations: [modelConfiguration])
} catch {
fatalError("Could not create ModelContainer: \(error)")
}
}()
var body: some Scene {
WindowGroup {
ContentView()
}
.modelContainer(sharedModelContainer)
}
}
I don't know where it comes from . I used IOS 17.5 I try to upgrade to IOS 18 but that didn't fix the problem. Currently I'm seeing 3 errors :

I hope someone helps me how to figure it out. Thank you!
It seems I can declare variables like below in a source file:
private let var1 = 1234
fileprivate let var2 = "abcd"
class MyClass {
// ...
}
So what's the difference between the 2 vars here?
I have a custom localisation function in my project that enforces the inclusion of the bundle parameter (specifically so that Swift packages are forced to include the Bundle.module value).
While migrating to String Catalogs, I noticed that my custom localisation function wasn't being recognised by the automatic extraction that the Swift compiler is doing, but only in my Swift package targets.
Is there a way to set something like LOCALIZED_STRING_MACRO_NAMES in Swift Packages?
Starting point
I have an app that is in production that has a single entity called CDShift. This is the class:
@Model
final class CDShift {
var identifier: UUID = UUID()
var date: Date = Date()
...
}
This is how this model is written in the current version.
Where I need to go
Now, I'm updating the app and I have to do some modifications, that are:
add a new entity, called DayPlan
add the relationship between DayPlan and CDShift
What I did is this:
enum SchemaV1: VersionedSchema {
static var versionIdentifier = Schema.Version(1, 0, 0)
static var models: [any PersistentModel.Type] {
[CDShift.self]
}
@Model
final class CDShift {
var identifier: UUID = UUID()
var date: Date = Date()
}
}
To encapsulate the current CDShift in a version 1 of the schema. Then I created the version 2:
enum SchemaV2: VersionedSchema {
static var versionIdentifier = Schema.Version(2, 0, 0)
static var models: [any PersistentModel.Type] {
[CDShift.self, DayPlan.self]
}
@Model
final class DayPlan {
var identifier: UUID = UUID()
var date: Date = Date()
@Relationship(inverse: \CDShift.dayPlan) var shifts: [CDShift]? = []
}
@Model
final class CDShift {
var identifier: UUID = UUID()
var date: Date = Date()
var dayPlan: DayPlan? = nil
}
}
The migration plan
Finally, I created the migration plan:
enum MigrationPlan: SchemaMigrationPlan {
static var schemas: [any VersionedSchema.Type] {
[SchemaV1.self, SchemaV2.self]
}
static let migrateV1toV2 = MigrationStage.custom(
fromVersion: SchemaV1.self,
toVersion: SchemaV2.self) { context in
// willMigrate, only access to old models
} didMigrate: { context in
// didMigrate, only access to new models
let shifts = try context.fetch(FetchDescriptor<SchemaV2.CDShift>())
for shift in shifts {
let dayPlan = DayPlan(date: shift.date)
dayPlan.shifts?.append(shift)
context.insert(dayPlan)
}
}
static var stages: [MigrationStage] {
print("MigrationPlan | stages called")
return [migrateV1toV2]
}
}
The ModelContainer
Last, but not least, how the model container is created in the App:
struct MyApp: App {
private let container: ModelContainer
init() {
container = ModelContainer.appContainer
}
var body: some Scene {
WindowGroup {
...
}
.modelContainer(container)
}
}
This is the extension of ModelContainer:
extension ModelContainer {
static var appContainer: ModelContainer {
let schema = Schema([
CDShift.self,
DayPlan.self
])
let modelConfiguration = ModelConfiguration(
schema: schema,
isStoredInMemoryOnly: Ecosystem.current.isPreview,
groupContainer: .identifier(Ecosystem.current.appGroupIdentifier)
)
do {
// let container = try ModelContainer(for: schema, configurations: modelConfiguration)
let container = try ModelContainer(for: schema, migrationPlan: MigrationPlan.self, configurations: modelConfiguration)
AMLogger.verbose("SwiftData path: \(modelConfiguration.url.path)")
return container
} catch (let error) {
fatalError("Could not create ModelContainer: \(error)")
}
}
}
The error
This has always worked perfectly until the migration. It crashes on the fatalError line, this is the error:
Unable to find a configuration named 'default' in the specified managed object model.
Notes
It seems that the version of the store is never updated to 2, but it keeps staying on 1. I tried also using the lightweight migration, no crash, it seems it recognizes the new entity, but the store version is always 1.
iCloud is enabled
I thought that the context used in the custom migration blocks is not the "right" one that I use when I create my container
If I use the lightweight migration, everything seems to work fine, but I have to manually do the association between the DayPlan and the CDShift objects
Do you have an idea on how to help in this case?

Hello,
I‘ve started developing an App not to long ago on Xcode and I have noticed that I can’t see any progress or like preview of what I have coded so far and it’s starting to concern me. I have Xcode version 15.5 and I am coding with swift, everything works fine there is no error or anything preventing it to run but when I try to preview the only thing I see when I launch the Simulator and I open my app the only thing I see is a white page.
Can someone please help me.
@discardableResult func doSomething() -> Bool {
// does something
return true
}
This function can be called in the following ways:
doSomething()
let didSucceed = doSomething()
Is there a way to differentiate the two from inside the doSomething() function, as in, is there a way to know if the caller is using the result?
I'm currently syncing core data with the CloudKit private and public databases, as you can see in the code below, I'm saving the private database in the default configuration in Core Data and the public in a configuration called Public everything works fine when NSPersistentCloudKitContainer syncs, what I'm having an issue with is trying to save to the public data store PublicStore, for instance when I try to save with func createIconImage(imageName: String) it saves the image to the "default" store, not the PublicStore(Public configuration).

Xcode says 'App' is only available in macOS 11.0 or newer when building an app with a package dependency. As soon as I remove the package, the errors disappear. I anyway set the minimum OS requirements as macOS 14.0+, so how does this error exist?
I am working on an iOS application using SwiftUI where I want to convert a JPG and a MOV file to a live photo. I am utilizing the LivePhoto Class from Github for this. The JPG and MOV files are displayed correctly in my WallpaperDetailView, but I am facing issues when trying to download the live photo to the gallery and generate the Live Photo.
Here is the relevant code and the errors I am encountering:
Console prints:
Play button should be visible Image URL fetched and set: Optional("https://firebasestorage.googleapis.com/...") Video is ready to play Video downloaded to: file:///var/mobile/Containers/Data/Application/.../tmp/CFNetworkDownload_7rW5ny.tmp Failed to generate Live Photo
I have verified that the app has the necessary permissions to access the Photo Library.
The JPEG and MOV files are successfully downloaded and can be displayed in the app.
The issue seems to occur when generating the Live Photo from the downloaded files.
