AuthenticateAsClient(this.Host、this.certificates、System.Security.Authentication.SslProtocols.Tls12,false)
Apple's push cannot receive information, use the open-source library JdSoft. Apple.Apns.Notifications Because I am not familiar with it, I modified Tls12. Does anyone know how to modify this open-source library to achieve push functionality apnsStream.AuthenticateAsClient(this.Host, this.certificates, System.Security.Authentication.SslProtocols.Tls12, false)

Xcode 16.3 Compile fails
After updating to 16.3, my project now fails to compile with the diagnostic: "Command SwiftCompile failed with a nonzero exit code". This is a SwiftUI document project with two local packages, the second of which is a rather large one with 112 SwiftUI files. It is this second package that is failing. There are no issues when compiling with 16.2. Without diagnostics I'm having a bit of difficulty in determining the cause. My thought is to regress the commits unit 16.3 gives a success, or shows issues. Although I'm not catching a similar issue in the forums, I'm seeing other problems with 16.3. Has anyone else had such build failure isolated to 16.3? Any advice on other ways to approach this problem? Thanks in advance

Xcode 16.3 C++ compiler makes binaries with corrupted memory.
I am creating an xcframework for a static library for iOS, but I am encountering a perplexing issue with Xcode 16.3. When I build an xcframework using C++ in one project and import it into another project, the application runs with corrupted memory. In the framework project, I use os_unfair_lock, but when attempting to lock, the app crashes due to a state error. This suggests that memory corruption is occurring. When the xcframework is built with Xcode 16.2, a proper binary is generated, and the app runs without any problems. Since I do not want to disclose the source code, I am trying to construct a minimal project that reproduces the issue, but so far I have not been successful. Fundamentally, I feel that the compiler in Xcode 16.3 cannot be trusted.

Content Blocker Disappears from Mac Safari Settings
I have had content blockers in the Mac App Store for years. Ever since moving to Sonoma, doing a clean build or archive in XCode deletes the extension from Safari settings since it never gets into the built app. The only way for me to get it back is to remove the DerivedData and target, reboot, and create a target with a different name. That works and stays around in Safari settings as long as I only build and don't clean. However, a clean or an archive removes it again. Restoring a version of the project from Time Machine that was posted to the App Store weeks or months ago doesn't work. However I can download the version of the app in the App Store, and it works, but I can't build it now from the source code that was used to build that version without going through the above process. Moving from Sonoma 14.7.1 to 14.7.2 didn't work. I would move to Sequoia if I had reason to believe that would work, but I don't. Safari 18.2, Sonoma 14.7.2, 32GB, 2.2 GHz 6-Core Intel Core i7

Why is there no Embed section in Xcode's Frameworks & Libraries section
If I create an Xcode (version doesn't matter, 16.N )project of type framework then install some dependencies using SPM. Then within the Frameworks and Libraries section, the Embed part is empty. This doesn't happen if the project type is app rather than framework. If I want to set this to embed or not embed then how can this be done if its not even visible, for that matter how can I tell what it is set to even?

Issue with react-native-vision-camera on iOS build - Compatibility and C++ Version Problem
Hi everyone, I'm encountering a persistent issue when trying to build my React Native project for iOS. I'm using the react-native-vision-camera library (version 4.6.4) and I've set my iOS deployment target to 16.0 in the app.json file. Despite this, the build process fails with an error related to the react-native-vision-camera pod, which seems to be stuck on an older version (2.15.4) that requires a different C++ version and a lower deployment target. Here's what I've tried so far: Ensured that the C++ version is set to 17 as required. Cleared and reinstalled all pods (rm -rf ios/Pods ios/Podfile.lock followed by pod install). Confirmed that the deploymentTarget in the app.json is set correctly to 16.0. However, the error persists and the build continues to fail, pointing to a compatibility issue with the react-native-vision-camera pod. I'm not sure if there's a cache issue or a configuration step I'm missing. Environment: React Native version: 0.76.7 react-native-vision-camera version: 4.6.4 iOS deployment target: 16.0 Expo SDK version: 52.0.40 Attached: app.json, eas.json, package.json, and the error log screenshot. Error log screnshot: Files: app.json eas.json package.json Any insights or suggestions from the community or Apple engineers would be greatly appreciated. Thank you!

Different Build Schemes -> Error: -Onone Swift optimization level to use previews
I have a sample SwiftUI iOS app. As shown in the screenshot below, my project has three configurations: Debug, MyDebug, Release. If I select the Debug or MyDebug scheme, I get a preview. But if I select the Release scheme, I get an error that says the following. ”***.app” needs -Onone Swift optimization level to use previews (current setting is -O) , where *** is the app name. It probably has nothing to do with the Preview error, but the Info.plist has a dictionary such that the key name is devMode, and the value is $(DEVMODE). And I have a user-defined setting as shown below. My ContentView has the following. import SwiftUI struct ContentView: View { @State private var state: String = "" var body: some View { VStack { Text("Hello, world!: \(state)") } .onAppear { if let devMode = Bundle.main.object(forInfoDictionaryKey: "devMode") as? String { print("Development mode: \(devMode)") state = devMode } if let path = Bundle.main.path(forResource: "Info", ofType: "plist") { if let dict = NSDictionary(contentsOfFile: path) { print("**** \(dict)") } } #if DEBUG print("Debug") #elseif MYDEBUG print("MyDebug") #else print("Que?") #endif } } } #Preview { ContentView() } So my question is how I get the preview for all three build schemes? Muchos thankos.

Xcode 16.3 Beta3: Developer Documentation Indexing does not end...resulting in Xcode CPU Usage high over long time.
macOS Version 15.3.2 (Build 24D81) After initiating via Shift/Command/0 the Developer Documentation Window, the indexing of v277 index structure is starting /Users/[name]/Library/Developer/Xcode/DocumentationCache/ ==> but unfortunately not ending! Activity Monitor reports during hours high CPU (~80%) for Xcode process, but the indexing does not stop or end. After hours it is still around 146 MB instead of about 550 MB as in previous releases. Indexing starts with 11 or more threads, but suddenly it drops to 10 threads and seems stopping, still using cpu. Also restarting Xcode does not help. Process restarts but after some minutes seems to hang or stuck around 200MB indexed. Also removing subfolders does not help. (NSOperatingSystemVersion(majorVersion/ 16, minorVersion/ 3, patchVersion/ 0) they are recreated but index still stucks after some time. No clue. will reverting back to 16.3 beta2 Reported via FB16926964

Errors compiling C++ code for x86_64
I have a project (that uses pre-compiled headers) that uses different compiler options for SOME files. For those files I have this is in my CMakelists.txt: if(CMAKE_C_COMPILER_ID MATCHES "GNU|Clang") set_source_files_properties(${AVX_Files} PROPERTIES COMPILE_OPTIONS "-mavx;-mavx2;-mfma;-mssse3;-msse4.2") set_source_files_properties(avx_simd_check.cpp PROPERTIES COMPILE_OPTIONS "-mxsave") endif() When I build for ARM, it all works :) When I try to build for X86_64, I get the following error for avx_simd_check.cpp: error: current translation unit is compiled with the target feature '+xsave' but the AST file was not 1 error generated. and for all the other files in question: error: current translation unit is compiled with the target feature '+avx' but the AST file was not error: current translation unit is compiled with the target feature '+avx2' but the AST file was not error: current translation unit is compiled with the target feature '+fma' but the AST file was not error: current translation unit is compiled with the target feature '+sse4.2' but the AST file was not error: current translation unit is compiled with the target feature '+ssse3' but the AST file was not 5 errors generated.

Code no longer builds "unsupported option for target"
A short while ago, I added: set(CMAKE_OSX_DEPLOYMENT_TARGET 13.0 CACHE STRING "Minimum operating system version for deployment") to my top level CMake file. The code would not compile. So I removed the line and deleted the CMake cache and tried to rebuild. And for my pains I got this: c++: error: unsupported option '-mavx' for target 'arm64-apple-darwin24.4.0' c++: error: unsupported option '-mavx2' for target 'arm64-apple-darwin24.4.0' c++: error: unsupported option '-mfma' for target 'arm64-apple-darwin24.4.0' c++: error: unsupported option '-mssse3' for target 'arm64-apple-darwin24.4.0' This code was all compiled just fine up until this change, but now it just won't do so. Help!!! David

Why Must All Attributes in a Composite Type Be Optional?
I recently encountered an issue involving Core Data’s new Composite Attributes feature and thought I would share my experience, as well as seek clarification. I created a composite type where all attributes were mandatory, except for one. Subsequently, I added an attribute to an entity and set its type to that composite type. Upon running the app, the console output the following error: CoreData: error: CoreData: error: Row (pk = 85) for entity ‘(EntityName)’ is missing mandatory text data for property ‘(propertyName)’ The way I resolved this was by removing the composite type attribute from the entity, after which the error no longer appeared. I also observed that in another entity, where a different composite type is used, all the attributes were optional — and no error occurred. This raises the question: why must all attributes in a composite type be optional? Furthermore, why does Xcode not inform the developer of this requirement? I have reviewed both the documentation and the WWDC23 “What’s New in Core Data” session, but neither mentions that having non-optional attributes within a composite type will cause such errors and lead to unpredictable application behaviour. Additionally, this issue remains unresolved in another area I raised previously in this topic: Composite Attributes feature requires tvOS deployment target 17.0 or later Composite Attributes feature requires watchOS deployment target 10.0 or later However, I do not have a tvOS or watchOS target, nor do I intend to add one. Could someone from Apple, or anyone with more experience, please clarify why all attributes within a composite type must be optional? And could it be possible for Xcode to flag this at compile time, rather than failing at runtime? Thank you in advance.

Xcode 16.3/macOS SDK 15.4: C++ features that required minimum target of 13.3 now require 13.4
C++ code that compiled fine on Xcode 16.2 when targeting macOS 13.3 after upgrading to Xcode 16.3 gives an error that the minimum required target is macOS 13.4 with an error like: `/Applications/Xcode-16.3.0.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.4.sdk/usr/include/c++/v1/__format/formatter_floating_point.h:74:30: error: 'to_chars' is unavailable: introduced in macOS 13.4 unknown 74 | to_chars_result __r = std::to_chars(__first, __last, __value, __fmt, __precision); Here’s example taken directly from (https://en.cppreference.com/w/cpp/utility/format/format): #include <format> #include <iostream> #include <string> #include <string_view> template<typename... Args> std::string dyna_print(std::string_view rt_fmt_str, Args&&... args) { return std::vformat(rt_fmt_str, std::make_format_args(args...)); } int main() { std::cout << std::format("Hello {}!\n", "world"); std::string fmt; for (int i{}; i != 3; ++i) { fmt += "{} "; // constructs the formatting string std::cout << fmt << " : "; std::cout << dyna_print(fmt, "alpha", 'Z', 3.14, "unused"); std::cout << '\n'; } } It doesn’t make any sense to suddenly require targeting 13.4 for features that worked fine on 13.3. The Apple documentation for C++ feature support explicitly discusses 13.3. https://developer.apple.com/xcode/cpp/ (search for P0067R5 on the page) I haven't tested it, but based on the standard library headers the minimum required iOS version has also been bumped - from 16.3 to 16.5. Am I doing something wrong? Is there a known work-around? Filed feedback: FB17081499

Issue with react-native-vision-camera on iOS build - Compatibility and C++ Version Problem
Hi everyone, I'm encountering a persistent issue when trying to build my React Native project for iOS. I'm using the react-native-vision-camera library (version 4.6.4) and I've set my iOS deployment target to 16.0 in the app.json file. Despite this, the build process fails with an error related to the react-native-vision-camera pod, which seems to be stuck on an older version (2.15.4) that requires a different C++ version and a lower deployment target. Here's what I've tried so far: Ensured that the C++ version is set to 17 as required. Cleared and reinstalled all pods (rm -rf ios/Pods ios/Podfile.lock followed by pod install). Confirmed that the deploymentTarget in the app.json is set correctly to 16.0. However, the error persists and the build continues to fail, pointing to a compatibility issue with the react-native-vision-camera pod. I'm not sure if there's a cache issue or a configuration step I'm missing. Environment: React Native version: 0.76.7 react-native-vision-camera version: 4.6.4 iOS deployment target: 16.0 Expo SDK version: 52.0.40 Attached: app.json, eas.json, package.json, and the error log screenshot. Error log screnshot: Files: app.json eas.json package.json Any insights or suggestions from the community or Apple engineers would be greatly appreciated. Thank you!

Different Build Schemes -> Error: -Onone Swift optimization level to use previews
I have a sample SwiftUI iOS app. As shown in the screenshot below, my project has three configurations: Debug, MyDebug, Release. If I select the Debug or MyDebug scheme, I get a preview. But if I select the Release scheme, I get an error that says the following. ”***.app” needs -Onone Swift optimization level to use previews (current setting is -O) , where *** is the app name. It probably has nothing to do with the Preview error, but the Info.plist has a dictionary such that the key name is devMode, and the value is $(DEVMODE). And I have a user-defined setting as shown below. My ContentView has the following. import SwiftUI struct ContentView: View { @State private var state: String = "" var body: some View { VStack { Text("Hello, world!: \(state)") } .onAppear { if let devMode = Bundle.main.object(forInfoDictionaryKey: "devMode") as? String { print("Development mode: \(devMode)") state = devMode } if let path = Bundle.main.path(forResource: "Info", ofType: "plist") { if let dict = NSDictionary(contentsOfFile: path) { print("**** \(dict)") } } #if DEBUG print("Debug") #elseif MYDEBUG print("MyDebug") #else print("Que?") #endif } } } #Preview { ContentView() } So my question is how I get the preview for all three build schemes? Muchos thankos.

Xcode 16.3 Beta3: Developer Documentation Indexing does not end...resulting in Xcode CPU Usage high over long time.
macOS Version 15.3.2 (Build 24D81) After initiating via Shift/Command/0 the Developer Documentation Window, the indexing of v277 index structure is starting /Users/[name]/Library/Developer/Xcode/DocumentationCache/ ==> but unfortunately not ending! Activity Monitor reports during hours high CPU (~80%) for Xcode process, but the indexing does not stop or end. After hours it is still around 146 MB instead of about 550 MB as in previous releases. Indexing starts with 11 or more threads, but suddenly it drops to 10 threads and seems stopping, still using cpu. Also restarting Xcode does not help. Process restarts but after some minutes seems to hang or stuck around 200MB indexed. Also removing subfolders does not help. (NSOperatingSystemVersion(majorVersion/ 16, minorVersion/ 3, patchVersion/ 0) they are recreated but index still stucks after some time. No clue. will reverting back to 16.3 beta2 Reported via FB16926964

Errors compiling C++ code for x86_64
I have a project (that uses pre-compiled headers) that uses different compiler options for SOME files. For those files I have this is in my CMakelists.txt: if(CMAKE_C_COMPILER_ID MATCHES "GNU|Clang") set_source_files_properties(${AVX_Files} PROPERTIES COMPILE_OPTIONS "-mavx;-mavx2;-mfma;-mssse3;-msse4.2") set_source_files_properties(avx_simd_check.cpp PROPERTIES COMPILE_OPTIONS "-mxsave") endif() When I build for ARM, it all works :) When I try to build for X86_64, I get the following error for avx_simd_check.cpp: error: current translation unit is compiled with the target feature '+xsave' but the AST file was not 1 error generated. and for all the other files in question: error: current translation unit is compiled with the target feature '+avx' but the AST file was not error: current translation unit is compiled with the target feature '+avx2' but the AST file was not error: current translation unit is compiled with the target feature '+fma' but the AST file was not error: current translation unit is compiled with the target feature '+sse4.2' but the AST file was not error: current translation unit is compiled with the target feature '+ssse3' but the AST file was not 5 errors generated. How can I solve this please? David

Code no longer builds "unsupported option for target"
A short while ago, I added: set(CMAKE_OSX_DEPLOYMENT_TARGET 13.0 CACHE STRING "Minimum operating system version for deployment") to my top level CMake file. The code would not compile. So I removed the line and deleted the CMake cache and tried to rebuild. And for my pains I got this: c++: error: unsupported option '-mavx' for target 'arm64-apple-darwin24.4.0' c++: error: unsupported option '-mavx2' for target 'arm64-apple-darwin24.4.0' c++: error: unsupported option '-mfma' for target 'arm64-apple-darwin24.4.0' c++: error: unsupported option '-mssse3' for target 'arm64-apple-darwin24.4.0' This code was all compiled just fine up until this change, but now it just won't do so. Help!!! David

Why Must All Attributes in a Composite Type Be Optional?
I recently encountered an issue involving Core Data’s new Composite Attributes feature and thought I would share my experience, as well as seek clarification. I created a composite type where all attributes were mandatory, except for one. Subsequently, I added an attribute to an entity and set its type to that composite type. Upon running the app, the console output the following error: CoreData: error: CoreData: error: Row (pk = 85) for entity ‘(EntityName)’ is missing mandatory text data for property ‘(propertyName)’ The way I resolved this was by removing the composite type attribute from the entity, after which the error no longer appeared. I also observed that in another entity, where a different composite type is used, all the attributes were optional — and no error occurred. This raises the question: why must all attributes in a composite type be optional? Furthermore, why does Xcode not inform the developer of this requirement? I have reviewed both the documentation and the WWDC23 “What’s New in Core Data” session, but neither mentions that having non-optional attributes within a composite type will cause such errors and lead to unpredictable application behaviour. Additionally, this issue remains unresolved in another area I raised previously in this topic: Composite Attributes feature requires tvOS deployment target 17.0 or later Composite Attributes feature requires watchOS deployment target 10.0 or later However, I do not have a tvOS or watchOS target, nor do I intend to add one. Could someone from Apple, or anyone with more experience, please clarify why all attributes within a composite type must be optional? And could it be possible for Xcode to flag this at compile time, rather than failing at runtime? Thank you in advance.

Cannot use instance member 'input_parameter' within property initializer; property initializers run before 'self' is available
I am passing UUID Key from View1 to View2. In View2, I need to Fetch entries using TabKey. userId is global variable working fine. Giving error TabKey. Please help. how to get rid of this error. If I keep this logic inside init method, Getting new error saying that "Cannot convert value of type 'FetchedResults' to expected argument type 'Binding' Here is the Code. @FetchRequest( sortDescriptors: [NSSortDescriptor(keyPath: \Table2.date, ascending: false)], predicate: { guard let currentUserId = AppSession.shared.currentUserId else { return NSPredicate(value: false) // Or handle the nil case as needed } return NSPredicate(format: "userId == %@ AND itemKey == %@", currentUserId as CVarArg, TabKey as CVarArg ) }(), animation: .default ) private var itab: FetchedResults

Xcode 16.3/macOS SDK 15.4: C++ features that required minimum target of 13.3 now require 13.4
C++ code that compiled fine on Xcode 16.2 when targeting macOS 13.3 after upgrading to Xcode 16.3 gives an error that the minimum required target is macOS 13.4 with an error like: `/Applications/Xcode-16.3.0.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.4.sdk/usr/include/c++/v1/__format/formatter_floating_point.h:74:30: error: 'to_chars' is unavailable: introduced in macOS 13.4 unknown 74 | to_chars_result __r = std::to_chars(__first, __last, __value, __fmt, __precision); Here’s example taken directly from (https://en.cppreference.com/w/cpp/utility/format/format): #include <format> #include <iostream> #include <string> #include <string_view> template<typename... Args> std::string dyna_print(std::string_view rt_fmt_str, Args&&... args) { return std::vformat(rt_fmt_str, std::make_format_args(args...)); } int main() { std::cout << std::format("Hello {}!\n", "world"); std::string fmt; for (int i{}; i != 3; ++i) { fmt += "{} "; // constructs the formatting string std::cout << fmt << " : "; std::cout << dyna_print(fmt, "alpha", 'Z', 3.14, "unused"); std::cout << '\n'; } } It doesn’t make any sense to suddenly require targeting 13.4 for features that worked fine on 13.3. The Apple documentation for C++ feature support explicitly discusses 13.3. https://developer.apple.com/xcode/cpp/ (search for P0067R5 on the page) I haven't tested it, but based on the standard library headers the minimum required iOS version has also been bumped - from 16.3 to 16.5. Am I doing something wrong? Is there a known work-around? Filed feedback: FB17081499
