I have a sandboxed app in /Applications. I'm attempting to shoot a problem with LLDB, so I cd to /Applications/app-name/Contents/MacOS and do lldb programname. However, once I fire it off with "r" it dies instantly with: error: process exited with status -1 (lost connection) Should this work? Should I try signing the lldb executable? Thanks!

I think I found a bug in the Objective-C++ compiler, linker, or runtime. Here’s the scenario: We have a macOS app written in Swift. To control hardware from a 3rd party manufacturer, we use a couple SDKs provided by the manufacturer. The SDKs use dynamically loaded libraries and the interface is defined in C++ headers. To bridge between our Swift code and the C++ APIs we have a private Cocoapod that wraps the 3rd party interface with Objective-C++ classes. The two SDKs each provide an interface for discovering attached devices using a callback class that the programmer provides. By accident we named both callback implementations DiscoveryCallback, but this was not a compiler error because neither class was publicly declared, and each was defined in the .mm file where it was used. However, the problem we’re seeing is this: We want to discover Videohub devices, so we register a new instance of DiscoveryCallback (defined in the same .mm file as this code) with the Videohub SDK. A Videohub device is connected and the SDK calls a method on our callback. Surprise! The callback we registered in step 1 was actually the one intended for Decklink devices, defined in a completely different .mm file. This violates all sorts of assumptions and our app quickly crashes. The funny thing is, the two implementations of DiscoveryCallback have completely different method names. The Videohub SDK is supposed to be calling NewVideohubDevice, yet somehow it successfully calls DeckLinkDeviceArrived on an instance of a class it shouldn’t even know about. So the compiler has checked that our intended DiscoveryCallback matches the protocol that the SDK expects, but at runtime the compiled code instantiates a completely different implementation of DiscoveryCallback and somehow doesn’t immediately fail; we still call a method on it that doesn’t even share a name with the intended target. I imagine at this point the method names are long forgotten and are just pointers in a table. I don’t know if this is a bug in the compiler, the Objective-C++ runtime, or if this is just “working as designed” undefined behavior that I should have avoided by not giving two private classes the same name. I know it’s possible to use a private API simply by redeclaring it in my own code, and this seems related to that, but I feel like the compiler or linker should have warned me that I had two implementations of the same class, or if that is not an error, then the runtime should have instantiated the class that was privately defined in the same source file where it was used. Obviously I can’t share our entire project; I’d like to provide some sample code that replicates the issue, but I don’t have time to do that right now. I’m posting this to see if other developers have had a similar experience.

Hello! I have an application written in Objective-c/C++ and I would like it to have support for OTA updates. I implemented the logic through two executable files, one of which was responsible for launching and updating the first, but this option did not pass Apple's review. Could you tell me how this functionality can be implemented and so that it meets the requirements of the App Store.

Hey guys, so I have a problem regarding the testIDs on my react native that is reproducible only on iOS DOM meaning that I set the ids individually on the elements on a page but the problem is that somehow the ids are concatenated between them and inherits all the ids under the parent. As you can see and imagine in the accessibility inspector, this is what my DOM looks like. I want to point out that the problem does not reproduce on Android, only on iOS. Can somebody help me with this and tell me if there is a way to disable this concatenation? What's relevant to tell you it's the fact that I need each element to have an unique ID for browserstack automated tests. But as you can see in the image an element contains all IDs concatenated for some reason. And here is the code for the page with this issue

I'm investigating an odd problem that surfaced with macOS Sequoia related to CoreGraphics (CGColorSpaceCreateWithICCData()). I couldn't find a reliable way to track the lifetime (retain/releases) of a CGColorSpaceRef (any pointers appreciated) so I was hoping to use objc_setAssociatedObject() to attach an instance of my own class that would be deallocated when the "owning" CGColorSpaceRef is deallocated. In this way I could set a breakpoint on my own code, presumably invoked when the CGColorSpaceRef is itself going away. While objc_setAssociatedObject() does seem to work, the results don't seem deterministic. Is it because objc_setAssociatedObject() simply won't work reliably with CF types?

I'm looking to do conditional programming with NEON. I try the __ARN_NEON tag. it doesn't work can you help me?

I am trying to embed a python file that uses a python library in c, to do this I need to include python.h but I don't see it anywhere on my mac. Right now when I try to compile I just get a missing Python.h compile error. I tried using the search bar to find it in /usr and /library. Neither had the file. I tried doing #include <Python/python.h> and that doesn't change anything. Is trying to setup a virtual env the issue?

I want to implement a stack that works quite like a circular buffer. void** pp = malloc(sizeof(id) * 100); pp[index] = someObject; // later on somewhere: MyObject* myObj = (MyObject*)pp[index]; Is this correct? Does this approach work with ARC?

Hi, is there an intrinsic instruction to shift a vector from another a shift vector? thank

My app creates dynamic copies of UI controls that are based on a custom UIButton subclass using this legacy approach: let archivedButton = try NSKeyedArchiver.archivedData(withRootObject: self, requiringSecureCoding: false) guard let buttonDuplicate = try NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(archivedButton) as? UIWagerButton else {return nil } I am currently trying to work passed the deprecation of NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(data: Data) Per the guidance, I should be replacing that line with the following and ensuring that the custom class implements NSSecureCoding guard let buttonDuplicate = try NSKeyedUnarchiver.unarchivedObject(ofClass: UIWagerButton.self, from: archivedButton) else {return nil} However, while the code does compile and run, decoding the data reference throws the following error: value for key 'UIButtonStatefulContent' was of unexpected class 'NSMutableDictionary' I can only assume that if I get passed this specific property, there will be other properties that are also problematic. Question: Is this a bug? Or, am I now responsible for navigating the underlying property matrix of this UIControl to specifically, manually, handle the encoding and decoding of each of it's properties?

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?

Hi I was using Xcode for c++ (for competitive programming purposes, not sure if this is the standard choice but using it anyway) I included a &lt;bits/stdc++.h&gt; to the include file for XCode.app and they didn't show any error. But then when I ran my code, it showed "Build Succeeded" although no output was visible.

Note that I am trying to build my project for IOS 18 using XCode version 16 Beta 6. I have version 18.0 of the iOS beta installed on my iPhone. My project includes pods for Firebase and GRPC-Core. I ran pod update and it installed Firebase (11.1.0), BoringSSL-GRPC 0.0.36, OpenSSL-Universal 3.3.1000, and gRPC-Core 1.65.5. When I try to build my project I encounter the following error: Undefined symbol: _c2i_ASN1_INTEGER This symbol is not referenced in my code. It's unclear which pod references this symbol - although Firebase is a likely candidate. Is anyone else encountering this issue? I'm wondering if I could safely go back to a version of Firebase that does, as the previous version I had installed (10.22.0) didn't have this issue.

after updating to macOS sequoia C++ compiler on vscode is not working is it just me or it is a common issue ?

Hi there, I’m having issue with the python3 installation provided by Xcode’s toolchain. I’m currently writing a LLDB plugin, using the LLDB python API, to allow the user to visualize audio data from the current debugged program in a GUI, using tkinter and matplotlib. I'm using those because I'm developing a cross-platform plugin, as I'm initially a Linux developer who wants to make this available to my fellow Apple audio devs. My issue arise at least on two setups MacOS 12.7.6 Monterey with Xcode 14.2 MacOS 14 with Xcode 15.4 (not my machine) Because I wanna support Xcode’s toolchain, I want to use Xcode’s lldb. Xcode’s lldb uses Xcode’s provided python, which I’m having issues with when loading tkinter.The issue can be reproduced like this : > xcrun python3 -c "import tkinter;tkinter._test()" macOS 12 (1207) or later required, have instead 12 (1206) ! zsh: abort xcrun python3 -c "import tkinter;tkinter._test()" On MacOS 14 the version numbers are : macOS 14 (1407) or later required, have instead 14 (1406) ! You can see it fails to load tkinter. From what I understood so far, it looks like the tkinter/tcl/tk version distributed with Xcode is not supported by MacOS ?I checked and the imported tkinter module is definitely the one provided by Xcode’s toolchain : # Checking where tkinter is installed > fd "^tkinter$" /Applications/Xcode.app /Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/tkinter/ /Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/tkinter/ /Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/site-packages/future/moves/tkinter/ # Checking that Xcode python uses the right module - it matches > xcrun python3 -c "import tkinter;print(tkinter.sys.modules['tkinter'])" <module 'tkinter' from '/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/tkinter/__init__.py'> I can get a working tkinter working by installing it using homebrew or macports, but I’m not able to use it with Xcode’s python installation. I tried overwriting sys.path to force Xcode’s python to import homebrew’s tkinter module, but it still loads Xcode’s tkinter .so. In the crash report I can see it indeed loads tcl/tk 8.5 and loads _tkinter.cpython-39-darwin.so from Xcode. I could disable the SIP (System Integrity Protection) to force to load another version of the library, but that wouldn’t be something I can ask the users. On the LLDB forum, they advise against using another python interpreter that the one provided by the toolchain. So is there a way to get the provided tkinter/tcl/tk installation to work ? If not I’m confused about why it’s provided in the first place. Thanks a lot for your time and please tell me if you have any questions. PS: if possible i'll post the head of the crash report in the comment of this post

I have a multi-platform application made with Delphi which uses FTDI D2XX drivers. All is well in other platforms but i have this issue in MacOS when i try to start the application: Termination Reason: Namespace DYLD, Code 1 Library missing Library not loaded: libftd2xx.dylib Referenced from: <CD2148C0-F76F-35D5-8E65-2BE51F201302> /Users/USER/*/USB_Editor.app/Contents/MacOS/USB_Editor Reason: tried: 'libftd2xx.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibftd2xx.dylib' (no such file), 'libftd2xx.dylib' (no such file), '//libftd2xx.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS//libftd2xx.dylib' (no such file), '//libftd2xx.dylib' (no such file) (terminated at launch; ignore backtrace) If i try to run the executable i get a similar error which includes the users/user folder in the paths specified above. So if i copy libftd2xx.dylib to users/user the app can start from the executable and the USB library works well. The library is bundled in Contents/Framework as this seems to be the best (or only) accepted practice. Btw the app only starts during deployment if the library is found in Contents/MacOS. Library version is the most recent from FTDI site for the ARM architecture and followed their instructions to install. If i try the otool command on the library i get this: otool -L libftd2xx.dylib libftd2xx.dylib: libftd2xx.dylib (compatibility version 1.1.0, current version 1.4.30) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1336.61.1) /usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 228.0.0) /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0) /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 2202.0.0) I'm a Mac user since last week so my knowledge of the system is not so good yet (:

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.
