We have FrameworkA which needs to use another FrameworkB internally to fetch a token. Now when I try to use this FrameworkA, we are seeing an issue with internal framework i.e. No such module 'FrameworkB'. But when I use @_implementationOnly import for the internal FrameworkB, I didn't see any issues. So just wanted to check If I can go ahead and use this @_implementationOnly import flag in Production?

When calling a perl script from an apple script (by dropping a file on it), I get the error: Can't load '/Library/Perl/5.34/darwin-thread-multi-2level/auto/Encode/Encode.bundle' for module Encode: dlopen(/Library/Perl/5.34/darwin-thread-multi-2level/auto/Encode/Encode.bundle, 0x0001): tried: '/Library/Perl/5.34/darwin-thread-multi-2level/auto/Encode/Encode.bundle' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '/System/Volumes/Preboot/Cryptexes/OS/Library/Perl/5.34/darwin-thread-multi-2level/auto/Encode/Encode.bundle' (no such file), '/Library/Perl/5.34/darwin-thread-multi-2level/auto/Encode/Encode.bundle' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')) at /System/Library/Perl/5.34/XSLoader.pm line 96. at /Library/Perl/5.34/darwin-thread-multi-2level/Encode.pm line 12. When I call the script manually from terminal, it runs fine. Why is Applescript running as X86 on M2?

Crash Log We have a issue with our watch app. When we do a release build with xcode 16 the watch app will not launch and crashes on watchOS 10 and below devices. It does not do this on debug builds...and it does not do this on xcode 15 release/debug builds. Anybody running into watch crashes on xcode 16? Thanks

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

Context: SwiftUI TextField with a String for simple math using NSExpression. I first prepare the input string to an extent but a malformed input using valid characters still fails, as expected. Let's say preparedExpression is "5--" let expr = NSExpression(format: preparedExpression) gives FAULT: NSInvalidArgumentException: Unable to parse the format string "5-- == 1"; (user info absent) How can I use NSExpression such that either the preparedExpression is pre-tested before asking for actual execution or the error is handled in a polite way that I can use to alert the user to try again. Is there a Swift alternative to NSExpression that I've missed?

I have a class object created dynamically using Runtime, and I want to release some manually allocated memory resources when this object is deallocated. To achieve this, I added a custom implementation of the dealloc method using the following code: SEL aSel = NSSelectorFromString(@"dealloc"); class_addMethod(kvoClass, aSel, (IMP)custom_dealloc, method_getTypeEncoding(class_getInstanceMethod(kvoClass, aSel))); However, I encountered some issues. If I don't call the superclass's dealloc method in the cus_dealloc function, the superclass's dealloc implementation will not be executed. On the other hand, if I explicitly call the superclass's dealloc method, the program crashes. Here is the implementation of the cus_dealloc function: void custom_dealloc(id self, SEL _cmd) { // Release other memory ![]("https://developer.apple.com/forums/content/attachment/c7b0c16b-be23-4776-b8db-f22b661c5e7d" "title=iShot_2025-01-03_19.31.34.png;width=1080;height=1895") Class superClass = class_getSuperclass(object_getClass(self)); void (*originIMP)(struct objc_super *, SEL, ...) = (void *)objc_msgSendSuper; struct objc_super *objcSuper = &(struct objc_super){self, superClass}; originIMP(objcSuper, _cmd); } demo

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.

Hi, I have issue on build my react native project and got this error "Undefined symbol: _swift_willThrowTypedImpl" how can I fix it?

I’m working on a project in Xcode 16.2 and encountered an issue where getAPI() with a default implementation in a protocol extension doesn’t show up in autocomplete. Here’s a simplified version of the code: import Foundation public protocol Repository { func getAPI(from url: String?) } extension Repository { public func getAPI(from url: String? = "https://...") { getAPI(from: url) } } final class _Repository: Repository { func getAPI(from url: String?) { // Task... } } let repo: Repository = _Repository() repo.getAPI( // Autocomplete doesn't suggest getAPI() I’ve tried the following without success: • Clean build folder • Restart Xcode • Reindexing Is there something wrong with the code, or is this a known issue with Xcode 16.2? I’d appreciate any insights or suggestions.

In my code I use a binding that use 2 methods to get and get a value. There is no problem with swift 5 but when I swift to swift 6 the compiler fails : Here a sample example of code to reproduce the problem : `import SwiftUI struct ContentView: View { @State private var isOn = false var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") Toggle("change it", isOn: Binding(get: getValue, set: setValue(_:))) } .padding() } private func getValue() -> Bool { isOn } private func setValue(_ value: Bool) { isOn = value } }` Xcode compiler log error : 1.

For my app I was trying to write some tests to ensure the functionality of all features. As I am using Xcode 16.0 I thought I might use Swift testing which was newly introduced and replaces XCTest. I created a new test target with Swift Testing and tried to run the first test, which was created automatically by the system. struct FinancialTests { @Test func testExample() async throws { #expect(true) } } Xcode is also showing the test diamond next to the function so I clicked on it to execute it. The app started to build and the build ended successfully. The the next step was testing. And after waiting for 10 minutes or so, no test was executed. First I thought maybe the test was not found, but in the test case overview all tests were shown: The run only shows this: Can someone help me to get this running. Many thanks!

I have a simple shell script as follows: #!/bin/bash OUTPUT="network.$(date +'%d-%m-%y').info.txt" SUPPORT_ID="emailaddress" echo "---------------------------------------------------" > $OUTPUT echo "Run date and time: $(date)" >> $OUTPUT echo "---------------------------------------------------" >> $OUTPUT ifconfig >> $OUTPUT echo "---------------------------------------------------" >> $OUTPUT echo "Network info written to file: $OUTPUT." echo "Please email this file to: $SUPPORT_ID." It just dumps the network config into a file. At some point I will have the file emailed out, but right now I'm just trying to figure out why the output looks like the following? bash ./test.sh .etwork info written to file: network.26-01-25.info.txt .lease email this file to: emailaddress Why in the world does the initial character of the last couple of "echo" commands get clipped and turned into periods? The echos for the output of the commands piped into the output file are fine. Strange... Any ideas?

I have a simple wrapper class around WCSession to allow for easier unit testing. I'm trying to update it to Swift 6 concurrency standards, but running into some issues. One of them is in the sendMessage function (docs here It takes [String: Any] as a param, and returns them as the reply. Here's my code that calls this: @discardableResult public func sendMessage(_ message: [String: Any]) async throws -> [String: Any] { return try await withCheckedThrowingContinuation { (continuation: CheckedContinuation<[String: Any], Error>) in wcSession.sendMessage(message) { response in continuation.resume(returning: response) // ERROR HERE } errorHandler: { error in continuation.resume(throwing: error) } } } However, I get this error: Sending 'response' risks causing data races; this is an error in the Swift 6 language mode Which I think is because Any is not Sendable. I tried casting [String: Any] to [String: any Sendable] but then it says: Conditional cast from '[String : Any]' to '[String : any Sendable]' always succeeds Any ideas on how to get this to work?

I’m aware that Xcode version 26 beta 3 provides an option to enable Swift’s Approachable Concurrency feature at the project level. However, I’d like to achieve the same for a Swift Package. Could you please advise on how to enable Approachable Concurrency support specifically for a Swift Package?

Hello everyone, There is one thing about Objective-C's memory management that confuses me, which is a returned object's lifetime from methods with names doesn't start with "alloc", "new", "copy", or "mutableCopy". Take this as an example, when using NSBitmapImageRep's representationUsingType:properties: method, it returns an NSData object (reference: https://developer.apple.com/documentation/appkit/nsbitmapimagerep/representation(using:properties:)?language=objc). While testing this out, the NSData seemed to be an owned object (it doesn't get released until the end of the program). From what I understand, this may be an auto-released object which is released at the end of an autorelease pool block. Could someone explain this in more detail? What if I want to release that NSData object before the end of the autorelease pool block? How can I know which object is autoreleased, borrowed, or owned?

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'm developing an audio unit for use on iOS. The AUv3 worked fine with xcode 15.X and swift 5.X. I recently tried to submit an update to my plug-in but Apple refused submission because my Xcode was not the latest. Now that I'm on Xcode 16.4 I can't get my project to compile, even when following all of the same previous steps. As one example of a change, Xcode doesn't appear to include the “C++ and Objective-C interoperability” build setting that it used to. This setting is noted in the Swift documentation and I used to need it, https://www.swift.org/documentation/cxx-interop/project-build-setup/#mixing-swift-and-c-using-xcode Currently my C++ code can't see anything from Swift, and I get a "Use of undeclared identifier 'project_name'". I've selected Switch support for version 5.0 in an attempt to minimize changes from Apple. My process is I generate an Xcode project file from my audio plugin support, JUCE. Then I add in the swift files, click yes to create bridging headers, but c++ doesn't see swift anymore. I'd greatly appreciate any suggestions.

I want to understand what the recommended way is for string interoperability between swift and c++. Below are the 3 ways to achieve it. Approach 2 is not allowed at work due to restrictions with using std libraries. Approach 1: In C++: char arr[] = "C++ String"; void * cppstring = arr; std::cout<<"before:"<<(char*)cppstring<<std::endl;           // C++ String // calling swift function and passing the void buffer to it, so that swift can update the buffer content Module1::SwiftClass:: ReceiveString (cppstring, length);   std::cout<<"after:"<<(char*)cppstring<<std::endl;             // SwiftStr      In Swift: func ReceiveString (pBuffer : UnsafeMutableRawPointer , pSize : UInt ) -> Void { // to convert cpp-str to swift-str: let swiftStr = String (cString: pBuffer.assumingMemoryBound(to: Int8.self)); print("pBuffer content: \(bufferAsString)"); // to modify cpp-str without converting: let swiftstr:String = "SwiftStr"      _ =  swiftstr.withCString { (cString: UnsafePointer<Int8>) in pBuffer.initializeMemory(as: Int8.self, from: cString, count: swiftstr.count+1) } }  Approach 2:  The ‘String’ type returned from a swift function is received as ‘swift::String’ type in cpp. This is implicitly casted to std::string type. The std::string has the method available to convert it to char *. void TWCppClass::StringConversion () {     // GetSwiftString() is a swift call that returns swift::String which can be received in std::string type     std::string stdstr = Module1::SwiftClass::GetSwiftString ();     char * cstr = stdstr.data ();     const char * conststr= stdstr.c_str (); }    Approach 3: The swift::String type that is obtained from a swift function can be received in char * by directly casting the address of the swift::String. We cannot directly receive a swift::String into a char *. void TWCppClass::StringConversion () {    // GetSwiftString() is a swift call that returns swift::String    swift::String swiftstr = Module1::SwiftClass::GetSwiftString ();    // obtaining the address of swift string and casting it into char *    char * cstr = (char*)&swiftstr; }

This is not a question but more of a hint where I was having trouble with. In my SwiftData App I wanted to move from Swift 5 to Swift 6, for that, as recommended, I stayed in Swift 5 language mode and set 'Strict Concurrency Checking' to 'Complete' within my build settings. It marked all the places where I was using predicates with the following warning: Type '' does not conform to the 'Sendable' protocol; this is an error in the Swift 6 language mode I had the same warnings for SortDescriptors. I spend quite some time searching the web and wrapping my head around how to solve that issue to be able to move to Swift 6. In the end I found this existing issue in the repository of the Swift Language https://github.com/swiftlang/swift/issues/68943. It says that this is not a warning that should be seen by the developer and in fact when turning Swift 6 language mode on those issues are not marked as errors. So if anyone is encountering this when trying to fix all issues while staying in Swift 5 language mode, ignore those, fix the other issues and turn on Swift 6 language mode and hopefully they are gone.

I am using swiftui lately in my iOS mobile app, The Mobile app already has a pipeline that detect any experimental features and throw an error I am using swift 5 and as you all know SwiftUI is using some of OpaqueTypeErasure utility types like "some" I heard that in swift 6 the OpaqueTypeErasure is not experimental anymore But upgrading the app swift version will be a very long process Also changing the pipeline will be a very long and tiring process So i want to know if there is a way to remove OpaqueTypeErasure from SwiftUI and what is the alternatives for bypassing the error that being thrown from the pipeline
