I am using CHCSVParser in objective-c to use the CSVString extension of the Array instance method. When I installed a new app on iOS18.1.1, the correct value (@"Application,"abc,def"") was returned for both the first and second turns, but when I installed a new app on iOS18.2, the correct value was returned for the first turn, but @"" was returned for the second turn. Even when I debug with step into, I can enter the CSVString for the first turn, but I cannot enter it for the second turn and after. It's as if the instance method is not being generated. There are in-app purchases between the first and second turns, but the view controllers that are called are also the same. Is there any change between iOS18.1.1 and iOS18.2?

We want to do below addition to iOS Mobile App. Airpod announces Push notification = which is workking now we want to use voice command that "Reply to this" and sending Reply to that notification but it is saying it is not supported in your app. So basically we need to use feature - Listen and respond to messages with AirPods Do we need to add any integration inside app for this or it will directly worked with Siri settings ? Is it possible to do in non messaging App? Is it possible to do without syncing contacts ?

We are Java application developers and we have a question regarding camera access via WebRTC on iPadOS. Specifically, on iPadOS 17.1, we are encountering an issue when trying to access the camera via the WKWebView API in the Chrome browser, where an error occurs and the camera capture fails. Our investigation suggests that device access through the navigator.mediaDevices property via the WKWebView API may not work in Chrome. However, it works as expected in the Safari browser, leading us to wonder if this is a Chrome-specific limitation, or if it's due to an iPadOS setting or specification. At this point, we are unsure if this issue is related to the WKWebView and WebRTC specifications on iPadOS 17.1, or if there are specific limitations in Chrome. We would appreciate any insights or solutions regarding camera access in iPadOS 17.1 with WKWebView and WebRTC, especially in relation to Chrome.

Hello, I have a problem with Xcode, in C++ language. When I create a new project, I put my program in a file and click Build. It works correctly and without any problems, but when I enter a second file in the same project and click build, it says build failed. In the log it says, duplicate symbols appear.

Hello everyone. macOS, IOBluetooth framework. My goal is to create a temporary SDP service. According to the documentation, by default a temporary service is created (aka Persistent = NO), which is deleted after the application is closed. The documentation also mentions the IOBluetoothRemoveServiceWithRecordHandle function for forced removal of the service. This function is deprecated and is currently unavailable. I guesse that it has been replaced by the IOBluetoothSDPServiceRecord.removeServiceRecord method. The essence of the problem is that the server is not deleted either using removeServiceRecord or even after app closing. That is, if you create several services and try to delete them, they will remain alive. Only turning Bluetooth off and on in the OS helps. I tested all versions of macOS starting with Monteray. The same behavior. for (int i = 0; i < 10; i++) { service = [IOBluetoothSDPServiceRecord publishedServiceRecordWithDictionary:dictionary]; if (!service) { NSLog(@"Failed to create service"); } else { [service getRFCOMMChannelID:&channelID]; [service getServiceRecordHandle:&serverHandle]; NSLog(@"A new service has been created handle=%u, channelID=%hhu", serverHandle, channelID); if (service.removeServiceRecord != kIOReturnSuccess) { NSLog(@"Failed to delete service"); } //service.release; service = nil; } } Can someone confirm this behavior? And is there a solution? A minimal test example is available at the link

Hello, I am a software engineer student and I have recently been getting problems on my Mac regarding the C/C++ libraries. I have used my macbook for uni work for months, but around 3 or 4 months ago my macbook could not compile my work since it couldnt find the basic libraries I was using. For example, iostream. I have been using VSCode, and what it exactly says is "cannot open source file "iostream". Please run the 'Select IntelliSense Configuration...' command to locate your system headers." I have tried researching, changing the include path, even using chatgpt, and nothing. Is anyone having this same problem, or is able to help me? If any other information is needed, please let me know!

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

In my project, i am initialising bytes with some character in cpp function, func CreateByteWithVal (), and passing to a function, func CreateNSStringFromCString(_ pPtr : UnsafeMutableRawPointer, _ pLength : Int), in swift using Swift-Cpp interop. CreateByteWithVal () allocates bytes on heap with value "AAAAAAAAAA", also calls swift function CreateNSStringFromCString. And func CreateNSStringFromCString (_ pPtr : UnsafeMutableRawPointer, _ pLength : Int) creates a NSString instance using NSString's BytesNoCopy initialiser using the bytes (pPtr) passed to it in parameter. Cpp code: void CppClass::CreateByteWithVal () { char * bytesForString = (char *) malloc (10); memset (bytesForString, 65, 10); Interop_Swift::CreateNSStringFromCString (bytesForString, 10); } Swift code: public func CreateNSStringFromCString (_ pPtr : UnsafeMutableRawPointer, _ pLength : Int) { let ns_string:NSString = NSString (bytesNoCopy: pPtr, length: pLength, encoding: String.Encoding.utf8.rawValue, freeWhenDone: false) } If we modify the byte values in memory from C++ directly, the NSString instance, which is supposed to be immutable by nature, reflects these changes. Is this approach appropriate, or is there something we're overlooking or need to address? In our project, we are mutating the byte values directly like this, and the changes are being reflected in the NSString instance : memset (bytesForString, 66, 5); Essentially, I want to confirm whether we can use this method to modify values through C++ without directly mutating the NSString instance. For the UI, we'll be reading the NSString instance by creating a native Swift String instance from it, like this: let str:String = ns_string as String Will the value of str remain consistent as long as we ensure that the correct bytes are provided by C++?

I have a simple shell script as follows: #!/bin/bash OUTPUT="network.$(date +'%d-%m-%y').info.txt" SUPPORT_ID="email" 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: email 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've created a Julia interface for Apple Accelerate's libSparse, via calling the library functions as if they were C (@ccall). I'm interested in using this in the context of power systems, where the sparse matrix is the Jacobian or the ABA matrix from a sparse grid network. However, I'm puzzled by the performance. I ran a sampling profiler on repeated in-place solves of Ax = b for a large sparse matrix A and random dense vectors b. (A is size 30k, positive definite so Cholesky factorization.) The 2 functions with the largest impact are _SparseConvertFromCoordinate_Double from libSparse.dylib, and BLASStateRelease from libBLAS.dylib. That strikes me as bizarre. This is an in-place solve: there should be minimal overheard from allocating/deallocating memory. Also, it seems strange that the library would repeatedly convert from coordinate form. Is this expected behavior? Thinking it might be an artifact of the Julia-C interface, I wrote up a similar program in C/Objective-C. I didn't profile it, but timing the same operation (repeated in-place solves of Ax = b for random vectors b, with the same matrix A as in the Julia) gave the same duration. I've attached the C/Objective-C below.profiling-comparison.m.txt If you're familiar with Julia, the following will give you the matrix I was working with: using PowerSystems, PowerNetworkMatrices sys = System("pglib_opf_case30000_goc.m") A = PowerNetworkMatrices.ABA_Matrix(sys).data where you can find the .m file here. (As a crude way to transfer A from Julia to C, I wrote the 3 arrays A.nzval, A.colptr, and A.rowval to .txt files as space-separated lists of numbers: the above C/objective-C reads in those files.) To duplicate my Julia profiling, do pkg> add AppleAccelerate#libSparse Profile--note the #libSparse part, these features aren't on the main branch--then run using AppleAccelerate, Profile # run previous code snippet to define A M, N = 10000, size(A)[1] bs = [rand(N) for _ in 1:M] aa_fact = AAFactorization(A) factor!(aa_fact) solve!(aa_fact, bs[1]) # pre-compile before we profile. Profile.init(n = 10^6, delay = 0.0003) @profile (for i in 1:M; solve!(aa_fact, bs[i]); end;) Profile.print(C = true, format = :flat, sortedby = :count)

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

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 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?
