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

Is there a way to achieve the following using C++/Swift interoperability: class MyCppClass { public: ... ... private: bool member1; ACppClass member2; ASwiftClass member3; } I'm aware of the recent C++/Objective-C interoperability compiler setting, but can't find any information on whether this is possible. I've watched the Apple video: https://developer.apple.com/videos/play/wwdc2023/10172/ and seen this post from Quinn: https://developer.apple.com/forums/thread/768928 but I don't see anyone discussing this kind of situation. Thanks in advance.

Hi I'm new here - I'm trying to learn Swift and SwiftUI. Tried on PluralSight and Udemy but they have been outdated and thus hard to follow. So after finding Apples own guides I felt relieved and happy, but now I'm stuck again. After they've updated Xcode to use #Preview instead of PreviewProvider it's hard to follow along on their tutorial. Does anyone know of good resources to study SwiftUI? Or know if apple plan to update their tutorials any time soon? I'm here now if anyone's interested or it's useful information: https://developer.apple.com/tutorials/app-dev-training/managing-state-and-life-cycle

Greetings! I am actively working on porting x64 code to Apple Silicon now that the time is nigh and part of the fundamentals of our software is a coroutine library for handling cooperative multitasking of GUI operations on the main thread. I was hoping to get the locations of the stack pointer and frame pointer in jmp_buf so, after setjmp() can redirect them to the primary handling routines in our coroutine library that handles the cooperative scheduling (which replaced and ported the old classic MP routines) which worked for PowerPC, i386 and x64. Any thoughts on where in the jmp_buf these might be located? I didn't see anything in the XNU open source. Any advice would be much obliged instead of having to dive in and re-implement these routines in assembly myself!

Hi, I am exploring Closures and trying to understand how they works. Closure have a special key feature that they can capture the context of the variables/constants from surroundings, once captured we can still use them inside the closure even if the scope in which they are defined does not exist. I want to understand the lifecycle of captured variable/constant i.e., where are these captured variables stored and when these get created and destroyed. How is memory managed for captured variables or constants in a closure, depending on whether they are value types or reference types?

As a fun project, I'm wanting to model an electronic circuit. Components inherit from a superclass (ElectronicComponent). Each subclass (e.g. Resistor) has certain methods to return properties (e.g. resistance), but may vary by the number of outlets (leads) they have, and what they are named. Each outlet connects to a Junction. In my code to assemble a circuit, while I'm able to manually hook up the outlets to the junctions, I'd like to be able to use code similar to the following… class Lead: Hashable // implementation omitted { let id = UUID() unowned let component: ElectronicComponent weak var connection: Junction? init(component: ElectronicComponent, to connection: Junction? = nil) { self.component = component self.connection = connection } } @dynamicMemberLookup class ElectronicComponent { let id = UUID() var connections: Set<Lead> = [] let label: String? init(label: String) { self.label = label } subscript<T>(dynamicMember keyPath: KeyPath<ElectronicComponent, T>) -> T { self[keyPath: keyPath] } func connect(lead: KeyPath<ElectronicComponent, Lead>, to junction: Junction) { let lead = self[keyPath: lead] lead.connection = junction connections.insert(lead) } } class Resistor: ElectronicComponent { var input, output: Lead? let resistance: Measurement<UnitElectricResistance> init(_ label: String, resistance: Measurement<UnitElectricResistance>) { self.resistance = resistance super.init(label: label) } } let resistorA = Resistor("R1", resistance: .init(value: 100, unit: .ohms)) let junctionA = Junction(name: "A") resistorA.connect(lead: \.outlet2, to: junctionA) While I'm able to do this by implementing @dynamicMemberLookup in each subclass, I'd like to be able to do this in the superclass to save repeating the code. subscript<T>(dynamicMember keyPath: KeyPath<ElectronicComponent, T>) -> T { self[keyPath: keyPath] } Unfortunately, the compiler is not allowing me to do this as the superclass doesn't know about the subclass properties, and at the call site, the subclass isn't seen as ElectronicComponent. I've been doing trial and error with protocol conformance and other things, but hitting walls each time. One possibility is replacing the set of outlets with a dictionary, and using Strings instead of key paths, but would prefer not to. Another thing I haven't tried is creating and adopting a protocol with the method implemented in there. Another considered approach is using macros in the subclasses, but I'd like to see if there is a possibility of achieving the goal using my current approach, for learning as much as anything.

We developing Native App with C++17 for iOS. We override global new and delete operators. This App deallocate all allocated memories correctly by Run on Xcode (Command + R), but exception occurs launch from xcrun or App icon on iPhone. I debugged the exception. Overriding new operation was called correctly, but overriding delete operation was not called. The default delete was called. I'm not sure why is that. STEPS TO REPRODUCE Build xcode project. Run "xcrun devicectl device install app --device " Run "xcrun devicectl device process launch --console --device " PLATFORM AND VERSION iOS Development environment: Xcode 16.4, macOS macOS Sequoia 15.5 Run-time configuration: iOS 18.5 main.cpp I attached is sample code to reproduce this problem. main.cpp

I have a Swift Package that contains an Objective-C target. The target contains Objective-C literals but unfortunately the compiler says "Initializer element is not a compile-time constant", what am I doing wrong? Based on the error triggering in the upper half, I take it that objc_array_literals is on. My target definition looks like: .target( name: "MyTarget", path: "Sources/MySourcesObjC", publicHeadersPath: "include", cxxSettings: [ .unsafeFlags("-fobjc-constant-literals") ] ), I believe Objective-C literals are enabled since a long time but I still tried passing in the -fobjc-constant-literals flag and no luck. To be clear I'm not interested in a run-time initialization, I really want it to be compile time. Does anyone know what I can do?

Does anyone know if there will be a Swift 6 version of "The Swift Programming Language" book and if so, when it will be released for Apple Books?

I've been teaching myself Objective-C and I wanted to start creating projects that don't use ARC to become better at memory management and learn how it all works. I've been attempting to build and run applications, but I'm not really sure where to start as modern iOS development is used with Swift and memory management is handled. Is there any way to create modern applications that use Objective-C, UIKit, and not use ARC?

Title Why doesn’t this async function see external changes to an inout Bool in Release builds (but works in Debug)? Body I have a small helper function that waits for a Bool flag to become true with a timeout: public func test(binding value: inout Bool, timeout maximum: Int) async throws { var count = 0 while value == false { count += 1 try await Task.sleep(nanoseconds: 0_100_000_000) if value == true { return } if count > (maximum * 10) { return } } } I call like this: var isVPNConnected = false adapter.start(tunnelConfiguration: tunnelConfiguration) { [weak self] adapterError in guard let self = self else { return } if let adapterError = adapterError { } else { isVPNConnected = true } completionHandler(adapterError) } try await waitUntilTrue(binding: &isVPNConnected, timeout: 10) What I expect: test should keep looping until flag becomes true (or the timeout is hit). When the second task sets flag = true, the first task should see that change and return. What actually happens: In Debug builds this behaves as expected: when the second task sets flag = true, the loop inside test eventually exits. In Release builds the function often never sees the change and gets stuck until the timeout (or forever, depending on the code). It looks like the while value == false condition is using some cached value and never observes the external write. So my questions are: Is the compiler allowed to assume that value (the inout Bool) does not change inside the loop, even though there are await suspension points and another task is mutating the same variable? Is this behavior officially “undefined” because I’m sharing a plain Bool across tasks without any synchronization (actors / locks / atomics), so the debug build just happens to work? What is the correct / idiomatic way in Swift concurrency to implement this kind of “wait until flag becomes true with timeout” pattern? Should I avoid inout here completely and use some other primitive (e.g. AsyncStream, CheckedContinuation, Actor, ManagedAtomic, etc.)? Is there any way to force the compiler to re-read the Bool from memory each iteration, or is that the wrong way to think about it? Environment (if it matters): Swift: [fill in your Swift version] Xcode: [fill in your Xcode version] Target: iOS / macOS [fill in as needed] Optimization: default Debug vs. Release settings I’d like to understand why Debug vs Release behaves differently here, and what the recommended design is for this kind of async waiting logic in Swift.

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?

Hi all, In Swift, I often see static helper functions grouped in an enum without any cases, like this: enum StringUtils { static func camelCaseToSnakeCase(_ input: String) -> String { // implementation } } Since this enum has no cases, it cannot be instantiated – which is exactly the point. It’s meant to group related functionality without any stored state, and without the need for instantiation. This pattern avoids writing a struct with a private init() and makes the intent clearer: "This is just a static utility, not an object." You’ll often see this used for things like: AnalyticsEvents.track(_:) My question: Is this use of a case-less enum considered good practice in Swift when building static-only helpers? Or is there a better alternative for expressing intent and preventing instantiation? I’d appreciate any insight – especially if there’s official guidance or references from the Swift core team. Thanks!

At least with macOS Sequoia 15.5 and Xcode 16.3: $ cat test.cc #include &amp;lt;locale.h&amp;gt; #include &amp;lt;string.h&amp;gt; #include &amp;lt;xlocale.h&amp;gt; int main(void) { locale_t l = newlocale(LC_ALL_MASK, "el_GR.UTF-8", 0); strxfrm_l(NULL, "ό", 0, l); return 0; } $ c99 test.c &amp;amp;&amp;amp; ./a.out Assertion failed: (p-&amp;gt;val == key), function lookup_substsearch, file collate.c, line 596.

Why doesn’t deinit support async? At the end of a test, I want to wipe data from HealthKit, and it’s delete function is asynchronous.

Is there any way that I can import a Java module for use from Swift?

I am using Xcode 15 and working on a localised app. I use the new String Catalogs feature which works great for my app. In my app I created some local package like Apple has done it in the Backyard Birds example. However the translations I did in the package's String Catalog won’t be used in the app. What am I doing wrong?

We have an iOS App built in .NET MAUI (Multi-platform App UI). This is a web view App. We wish to integrate APP Clips into this App. But we are unable to do it, due to less available resources online on such implementation. We do not wish to share code between .NET MAUI App and App clips We understand it is not possible to add APP Clips without a parent swift/Xcode app. As an alternative solution we were thinking to Create a new APP in APP Store Connect using XCode/swift and integrate app clips to it. This parent app when downloaded by users will only redirect users to our MAIN .NET MAUI app to app store connect. We need to know if such apps will be approved by APPSTORE Connect? Please guide us on this Also please do let us know if you have any other solution to integrate App clips to a .NET MAUI App
