I have a string of the form “Mon 22nd April”. I’m trying to extract the day (i.e. Mon), the date (i.e. 22nd) and the month (i.e. April) using this Applescript: set originalDateString to “Mon 22nd April” -- Extract the components by splitting the string set AppleScript's text item delimiters to " " set dayOfWeekAbbrev to text item 1 of originalDateString set dayOfMonth to text item 2 of originalDateString set monthName to text item 3 of originalDateString When I run this on its own it works as expected: dayOfWeekAbbrev is set to “Mon” dayOfMonth is set to “22nd” monthName is set to “April” When I run this inside a bigger script involving Numbers, the text item delimiters fails to work, no compile or run time errors occur and I end up with: dayOfWeekAbbrev is set to “M” dayOfMonth is set to “o” monthName is set to “n” I.e the first three characters of the string. If I replace originalDateString with the literal string “Mon 22nd April” I get the same result. In other words, text items and being recognized as individual characters, no delimiter (or delimiter is null). Totally confused.

My company wants to be insure that if my Objective-C to Swift conversions fail in anyway, that the app can revert to using the older Objective-C code. By using a remotely controllable flag, the app can switch which code runs as, both are compiled into the app. Essentially, I create a protocol that describes the original class, then both classes (with a "s" or "o" appended to them) conform to the protocol. Protocol: Object Objective-C class: oObject Swift class: sObject That said, I hit one issue that I just can't seem reason out. I create a Objective-C function that returns the appropriate class: Class<Object> classObject(void) { if (myFlag) { return [sObject class]; } else { return [oObject class]; } } Swift deals with this really well - I can create an initialized object using: let object = classObject().init() but I cannot find a way to do this in Objective-C: Object *object = [[classSalesForceData() alloc] init]; fails with "No known class method for selector 'alloc'" Is there a way to do this? David PS: my workaround is to return an allocated object: Object *createObject(void) { if (myFlag) { return [sObject alloc]; } else { return [oObject alloc]; } }

macOS: Sequoia Xcode: 16.1 I am working on a macOS app and it has a widget feature. When I use Swift 6 (Build Settings > Swift Language Version) in IntentExtension, the intent configuration won't show up in macOS Sequoia. If I downgrade to Swift 5, it works without any other changes. Is it a bug or am I missing something? How can I use Swift 6 with IntentExtension.

Hi, I have a complex structure of classes, and I'm trying to migrate to swift6 For this classes I've a facade that creates the classes for me without disclosing their internals, only conforming to a known protocol I think I've hit a hard wall in my knowledge of how the actors can exchange data between themselves. I've created a small piece of code that can trigger the error I've hit import SwiftUI import Observation @globalActor actor MyActor { static let shared: some Actor = MyActor() init() { } } @MyActor protocol ProtocolMyActor { var value: String { get } func set(value: String) } @MyActor func make(value: String) -> ProtocolMyActor { return ImplementationMyActor(value: value) } class ImplementationMyActor: ProtocolMyActor { private(set) var value: String init(value: String) { self.value = value } func set(value: String) { self.value = value } } @MainActor @Observable class ViewObserver { let implementation: ProtocolMyActor var value: String init() async { let implementation = await make(value: "Ciao") self.implementation = implementation self.value = await implementation.value } func set(value: String) { Task { await implementation.set(value: value) self.value = value } } } struct MyObservedView: View { @State var model: ViewObserver? var body: some View { if let model { Button("Loaded \(model.value)") { model.set(value: ["A", "B", "C"].randomElement()!) } } else { Text("Loading") .task { self.model = await ViewObserver() } } } } The error Non-sendable type 'any ProtocolMyActor' passed in implicitly asynchronous call to global actor 'MyActor'-isolated property 'value' cannot cross actor boundary Occurs in the init on the line "self.value = await implementation.value" I don't know which concurrency error happens... Yes the init is in the MainActor , but the ProtocolMyActor data can only be accessed in a MyActor queue, so no data races can happen... and each access in my ImplementationMyActor uses await, so I'm not reading or writing the object from a different actor, I just pass sendable values as parameter to a function of the object.. can anybody help me understand better this piece of concurrency problem? Thanks

I have a VPN application published in the app store. Used Ikev2 for this personal VPN. There are two in-app purchases. One is 'Monthly' and another is 'Yearly' with 3 days free trial. We have seen something strange for the yearly subscriptions which has free trail, the cancellation reason through the billing issue is too high like 70-80% due to billing retry state. Some other apps which have billing issues under 10% always. We have done some research and found that if the user doesn't cancel and Apple is unable to charge then it goes to a billing retry state. If users don't like the app, they could cancel their subscription/free trail easily but they are not doing this and why Apple unable to charge the bill after the trial ends. Am i missing something in the developer end?

I want to be able to write a cross-platform screensaver that works on both Windows and macOS using the Pygame 2D graphics library in Python. On Windows, this is super easy - you just write your program with three possible command line arguments: /p for preview mode, /c for the configuration dialog mode, and /s for the actual full-screen screensaver mode. Then you just use pyinstaller to build an .exe file and rename the extension to .scr, and you're good to go. However, it seems that making a screensaver on macOS is a pretty convoluted process, and there was stuff about specific Objective-C functions that you had to write, and I didn't really understand the documentation. Could you please tell me if there is any way to simply get my Python Pygame program to build as a proper .saver file? Thanks!

Hi Everyone, I was able to create the String Catalog with all my strings getting automatic into the stringCatalog except the strings from my models where is not swiftUI and where all I have a class with a lot of info for my app. Some classes are short and I was able to just make the strings localizable by adding on every line: (String(localized: "Telefone")) But I have one class which has Line: 1071 and Col: 1610 and every line I have 7 strings that needs to get localized. These 7 strings are repeated on every line. So I was trying to create a localization for these 7 strings on this class without having to write (String(localized: "Telefone")) 7 times on every line. is there a way? Here is short version of my class: import Foundation class LensStructFilter: Identifiable { var description: String init(description: String) { self.description = description } } let lensEntriesFilter: [LensStructFilter] = [ LensStructFilter(description: "Focal: 24mm \nAbertura Máxima: F2.8 \nCobertura: FULL FRAME \nBocal: Nikon F \nFoco Mínimo: 0,30m \nDiâmetro Frontal: 52mm \nPeso: 275g \n\nFocal: 35mm \nAbertura Máxima: F2.0 \nCobertura: FULL FRAME \nBocal: Nikon F \nFoco Mínimo: 0,25m \nDiâmetro Frontal: 52mm \nPeso: 205g \n\nFocal: 50mm \nAbertura Máxima: F1.8 \nCobertura: FULL FRAME \nBocal: Nikon F \nFoco Mínimo: 0,45m \nDiâmetro Frontal: 52mm \nPeso: 185g \n\nFocal: 85mm \nAbertura Máxima: F1.8 \nCobertura: FULL FRAME \nBocal: Nikon F \nFoco Mínimo: 0,80m \nDiâmetro Frontal: 67mm \nPeso: 350g \n\nFocal: 105mm MACRO \nAbertura Máxima: F2.8 \nCobertura: FULL FRAME \nBocal: Nikon F \nFoco Mínimo: 0,31m \nDiâmetro Frontal: 62mm \nPeso: 720g"), LensStructFilter(description: "Focal: 16-35mm  \nAbertura Máxima: F2.8 \nCobertura: FULL FRAME  \nBocal: EF \nFoco Mínimo: 0,28m \nDiâmetro Frontal (rosca): 82mm \nPeso: 790Kg"), Thanks

I ran into a memory issue that I don't understand why this could happen. For me, It seems like ARC doesn't guarantee thread-safety. Let see the code below @propertyWrapper public struct AtomicCollection&lt;T&gt; { private var value: [T] private var lock = NSLock() public var wrappedValue: [T] { set { lock.lock() defer { lock.unlock() } value = newValue } get { lock.lock() defer { lock.unlock() } return value } } public init(wrappedValue: [T]) { self.value = wrappedValue } } final class CollectionTest: XCTestCase { func testExample() throws { let rounds = 10000 let exp = expectation(description: "test") exp.expectedFulfillmentCount = rounds @AtomicCollection var array: [Int] = [] for i in 0..&lt;rounds { DispatchQueue.global().async { array.append(i) exp.fulfill() } } wait(for: [exp]) } } It will crash for various reasons (see screenshots below) I know that the test doesn't reflect typical application usage. My app is quite different from traditional app so the code above is just the simplest form for proof of the issue. One more thing to mention here is that array.count won't be equal to 10,000 as expected (probably because of copy-on-write snapshot) So my questions are Is this a bug/undefined behavior/expected behavior of Swift/Obj-c ARC? Why this could happen? Any solutions suggest? How do you usually deal with thread-safe collection (array, dict, set)?

Every time a (valid) vector instruction is added to the .s file, xcode report an error (without vector instruction the .s file compile correctly) By example vand q8, q8, q10 found in https://developer.apple.com/forums/thread/104424 give an error What I am missing to tell xcode to accept vector instruction ?

I'm trying to use FormatStyle from Foundation to format numbers when printing a vector structure. See code below. import Foundation struct Vector<T> { var values: [T] subscript(item: Int) -> T { get { values[item] } set { values[item] = newValue } } } extension Vector: CustomStringConvertible { var description: String { var desc = "( " desc += values.map { "\($0)" }.joined(separator: " ") desc += " )" return desc } } extension Vector { func formatted<F: FormatStyle>(_ style: F) -> String where F.FormatInput == T, F.FormatOutput == String { var desc = "( " desc += values.map { style.format($0) }.joined(separator: " ") desc += " )" return desc } } In the example below, the vector contains a mix of integer and float literals. The result is a vector with a type of Vector<Double>. Since the values of the vector are inferred as Double then I expect the print output to display as decimal numbers. However, the .number formatted output seems to ignore the vector type and print the values as a mix of integers and decimals. This is fixed by explicitly providing a format style with a fraction length. So why is the .formatted(.number) method ignoring the vector type T which is Double in this example? let vec = Vector(values: [-2, 5.5, 100, 19, 4, 8.37]) print(vec) print(vec.formatted(.number)) print(vec.formatted(.number.precision(.fractionLength(1...)))) ( -2.0 5.5 100.0 19.0 4.0 8.37 ) // correct output that uses all Double types ( -2 5.5 100 19 4 8.37 ) // wrong output that uses Int and Double types ( -2.0 5.5 100.0 19.0 4.0 8.37 ) // correct output that uses all Double types

I have an app whose logic is in C++ and rest of the parts (UI) are in Swift and SwiftUI. Exceptions can occur in C++ and Swift. I've got the C++ part covered by using the Linux's signal handler mechanism to trap signals which get raised due to exceptions. But how should I capture exceptions in Swift? When I say exceptions in Swift, I mean, divide by zero, force unwrapping of an optional containing nil, out of index access in an array, etc. Basically, anything that can go wrong, I don't want my app to abruptly crash... I need a chance to finalise my stuff, alert the user, prepare diagnostic reports and terminate. I'm looking for a 'catch-all' exception handler. As an example, let's take Android. In Android, there is the setDefaultUncaughtExceptionHandler method to register for all kinds of exceptions in any thread in Kotlin. I'm looking for something similar in Swift that should work for macOS, iOS &amp; iPadOS, tvOS and watchOS. I first came across the NSSetUncaughtExceptionHandler method. My understanding is, this only works when I explicitly raise NSExceptions. When I tested it, observed that the exception handler didn't get invoked for either case - divide by zero or invoking raise. class AppDelegate: NSObject, NSApplicationDelegate { func applicationDidFinishLaunching(_ aNotification: Notification) { Log("AppDelegate.applicationDidFinishLaunching(_:)") // Set the 'catch-all' exception handler for Swift exceptions. Log("Registering exception handler using NSSetUncaughtExceptionHandler()...") NSSetUncaughtExceptionHandler { (exception: NSException) in Log("AppDelegate.NSUncaughtExceptionHandler()") Log("Exception: \(exception)") } Log("Registering exception handler using NSSetUncaughtExceptionHandler() succeeded!") // For C++, use the Linux's signal mechanism. ExceptionHandlingCpp.RegisterSignals() //ExceptionHandlingCpp.TestExceptionHandler() AppDelegate.TestExceptionHandlerSwift() } static func TestExceptionHandlerSwift() { Log("AppDelegate.TestExceptionHandlerSwift()") DivisionByZero(0) } private static func DivisionByZero(_ divisor: Int) { Log("AppDelegate.DivisionByZero()") let num1: Int = 2 Log("Raising Exception...") //let result: Int = num1/divisor let exception: NSException = NSException(name: NSExceptionName(rawValue: "arbitrary"), reason: "arbitrary reason", userInfo: nil) exception.raise() Log("Returning from DivisionByZero()") } } In the above code, dividing by zero, nor raising a NSException invokes the closure passed to NSSetUncaughtExceptionHandler, evident from the following output logs AppDelegate.applicationWillFinishLaunching(_:) AppDelegate.applicationDidFinishLaunching(_:) Registering exception handler using NSSetUncaughtExceptionHandler()... Registering exception handler using NSSetUncaughtExceptionHandler() succeeded! ExceptionHandlingCpp::RegisterSignals() .... AppDelegate.TestExceptionHandlerSwift() AppDelegate.DivisionByZero() Raising Exception... Currently, I'm reading about ExceptionHandling framework, but this is valid only for macOS. What is the recommended way to capture runtime issues in Swift?

I am writing a SPM based project for MacOS. In this project? I need to access MacOS Keychain. I am write a swift test built by SPM testTarget(). I can see it generates a bundle ./.build/x86_64-apple-macosx/debug/MyProjectTests.xctest with an executable: % file ./.build/x86_64-apple-macosx/debug/MyProjectPackageTests.xctest/Contents/MacOS/MyProjectPackageTests ./.build/x86_64-apple-macosx/debug/MyProjectPackageTests.xctest/Contents/MacOS/MyProjectPackageTests: Mach-O 64-bit bundle x86_64 This bundle file cannot be executed. How can I execute its tests? I tried with xcodebuild test-without-building -xctestrun ./.build/x86_64-apple-macosx/debug/MyProjectPackageTests.xctest -destination 'platform=macOS' without any chance. Obviously the next question is can I 'simply' add entitlement to this bundle with codesign to fix my enttilement error. My error when running the test is A required entitlement isn't present.

Hello Everyone, I have a use case where I wanted to interpret the "Data" object received as a part of my NWConnection's recv call. I have my interpretation logic in cpp so in swift I extract the pointer to the raw bytes from Data and pass it to cpp as a UnsafeMutableRawPointer. In cpp it is received as a void * where I typecast it to char * to read data byte by byte before framing a response. I am able to get the pointer of the bytes by using // Swift Code // pContent is the received Data if let content = pContent, !content.isEmpty { bytes = content.withUnsafeBytes { rawBufferPointer in guard let buffer = rawBufferPointer.baseAddress else { // return with null data. } // invoke cpp method to interpret data and trigger response. } // Cpp Code void InterpretResponse (void * pDataPointer, int pDataLength) { char * data = (char *) pDataPointer; for (int iterator = 0; iterator < pDataLength; ++iterator ) { std::cout << data<< std::endl; data++; } } When I pass this buffer to cpp, I am unable to interpret it properly. Can someone help me out here? Thanks :) Harshal

I am trying to use initialize a Decimal type using its generic binary integer exactly initializer but it keeps crashing with a fatal error regardless of the value used: Code to reproduce the issue: let binaryInteger = -10 let decimal = Decimal(exactly: binaryInteger) // error: Execution was interrupted, reason: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0). Is it a known bug?

What is the most obvious method of calling StoreKit from C++. I'm getting blocked by the fact that most of the critical StoreKit calls are async and functions marked a sync don't show up in the swift header for me to call from C++ (at least as far as I can tell). I'm trying to call let result = try await Product.products(for:productIDs) or let result = try await product.purchase() And C++ can't even see any functions I wrap these in as far as I can tell because i have to make them async. What am I missing? I tried a lot of alternates, like wrapping in Task { let result = try await Product.products(for:productIDs) } and it gives me 'Passing closure as a sending parameter' errors. Also when I try to call the same above code it gives me 'initializtion of immutable value never used' errors and the variables never appear. Code: struct storeChooser { public var productIDs: [String] public function checkProduct1 { Task { let result = try await Product.products(for: productIDs) } The above gives the initialization of immutable value skipped, and when I create a @State var products Then I get the 'passing closure as a sending parameter' error when i try to run it in a task it appears if I could make the function async and call it from C++ and have it return nothing it may work, does anyone know how to get C++ to see an async function in the -Swift.h file?

Hi Apple Developer Community, I'm facing a crash when updating an array of tuples from both a background thread and the main thread simultaneously. Here's a simplified version of the code in a macOS app using AppKit: class ViewController: NSViewController { var mainthreadButton = NSButton(title: "test", target: self, action: nil) var numbers = Array(repeating: (dim: Int, key: String)(0, "default"), count: 1000) override func viewDidLoad() { super.viewDidLoad() view.addSubview(mainthreadButton) mainthreadButton.translatesAutoresizingMaskIntoConstraints = false mainthreadButton.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true mainthreadButton.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true mainthreadButton.widthAnchor.constraint(equalToConstant: 100).isActive = true mainthreadButton.heightAnchor.constraint(equalToConstant: 100).isActive = true mainthreadButton.target = self mainthreadButton.action = #selector(arraytest(_:)) } @objc func arraytest(_ sender: NSButton) { print("array update started") // Background update DispatchQueue.global().async { for i in 0..&lt;1000 { self.numbers[i].dim = i } } // Main thread update var sum = 0 for i in 0..&lt;1000 { numbers[i].dim = i + 1 sum += numbers[i].dim print("test \(sum)") } mainthreadButton.title = "test = \(sum)" } } This results in a crash with the following message: malloc: double free for ptr 0x136040c00 malloc: *** set a breakpoint in malloc_error_break to debug What's interesting: This crash only happens when the tuple contains a String ((dim: Int, key: String)) If I change the tuple type to use two Int values ((dim: Int, key: Int)), the crash does not occur My Questions: Why does mutating an array of tuples containing a String crash when accessed from multiple threads? Why is the crash avoided when the tuple contains only primitive types like Int? Is there an underlying memory management issue with value types containing reference types like String? Any explanation about this behavior and best practices for thread-safe mutation of such arrays would be much appreciated. Thanks in advance!

As I migrate my apps to Swift 6 one by one, I am gaining a deeper understanding of concurrency. In the process, I am quite satisfied to see the performance benefits of parallel programming being integrated into my apps. At the same time, I have come to think that actor is a great type for addressing the 'data race' issues that can arise when using the 'singleton' pattern with class. Specifically, by using actor, you no longer need to write code like private let lock = DispatchQueue(label: "com.singleton.lock") to prevent data races that you would normally have to deal with when creating a singleton with a class. It reduces the risk of developer mistakes. import EventKit actor EKDataStore: Sendable { static let shared = EKDataStore() let eventStore: EKEventStore private init() { self.eventStore = EKEventStore() } } Of course, since a singleton is an object used globally, it can become harder to manage dependencies over time. There's also the downside of not being able to inject dependencies, which makes testing more difficult. I still think the singleton pattern is ideal for objects that need to be maintained throughout the entire lifecycle of the app with only one instance. The EKDataStore example I gave is such an object. I’d love to hear other iOS developers' opinions, and I would appreciate any advice on whether I might be missing something 🙏

` init() { nextOrder = self.AllItems.map{$0.order}.max() if nextOrder == nil { nextOrder = 0 } nextOrder! += 1 // <--- Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value } ` I have to say, Swift is great - when it works!

No real intruduction for this, so I'll get to the point: All this code is on GitHub: https://github.com/the-trumpeter/Timetaber-for-iWatch But first, sorry; /* I got roasted, last time I posted; for not defining my stuff.
