I have an XPC service that embeds Python. It executes a python script on behalf of the main app. The app and xpc service are sandboxed. All seems to work just fine in the development environment but the script fails in the released version. I disabled writing pycache by setting the PYTHONDONTWRITEBYTECODE environment variable because pycache tries to write inside my app bundle which fails (I believe I can redirect the pycache directory with PYTHONPYCACHEPREFIX and may experiment with that later). Specifically this line fails in the release version only (not from Xcode): PyObject *pModule = PyImport_Import(moduleNameHere); if (pModuleOwnedRef == NULL) { // this is null in release mode only. } Any ideas what can be going wrong? Thanks in advance.

I have a simple little Mac app that embeds a Python interpreter. I wrote this app almost ten years ago and completely forgot about it. Anyway I submitted an update to it with a new version of Python but it's being rejected by App review for the following reason: Your app uses or references the following non-public or deprecated APIs: Symbols: • _Tcl_NewByteArrayObj • _Tcl_ResetResult • _Tcl_MutexLock • _Tcl_GetBooleanFromObj • _Tcl_SetObjResult • _Tcl_CreateInterp • _Tcl_ThreadQueueEvent • _Tcl_UnsetVar2 • _Tcl_GetBignumFromObj • _TclBN_mp_to_unsigned_bin_n • _Tcl_ListObjLength • _Tcl_ConditionWait • _Tcl_GetDouble • _Tcl_GetDouble • _Tcl_DeleteFileHandler • _Tcl_SetVar • _Tcl_SetVar • _Tcl_SetVar • _Tcl_DoOneEvent • _TclFreeObj • _Tcl_Eval • _Tcl_Eval • _Tcl_Eval • _Tcl_FindExecutable • _Tcl_NewLongObj • _Tcl_CreateTimerHandler • _Tcl_Init • _Tcl_ConditionFinalize • _Tcl_GetByteArrayFromObj • _Tcl_ListObjIndex • _Tcl_ExprLong • _Tcl_NewDoubleObj • _Tcl_GetDoubleFromObj • _Tcl_ExprString • _TclBN_mp_read_radix • _Tcl_DeleteTimerHandler • _Tcl_CreateFileHandler • _Tcl_GetVar • _Tcl_GetVar • _Tcl_CreateObjCommand • _Tcl_SetVar2Ex • _Tcl_GetStringFromObj • _Tcl_NewStringObj • _Tcl_GetObjType • _Tcl_MutexUnlock • _Tcl_DeleteCommand • _TclBN_mp_init • _Tcl_GetCurrentThread • _Tcl_ExprDouble • _Tcl_AddErrorInfo • _Tcl_Free • _Tcl_GetStringResult • _Tcl_SetVar2 • _Tcl_SetVar2 • _Tcl_GetBoolean • _Tcl_GetBoolean • _Tcl_RecordAndEval • _Tcl_EvalFile • _Tcl_GetLongFromObj • _TclBN_mp_clear • _Tcl_ThreadAlert • _Tcl_ExprBoolean • _Tcl_DeleteInterp • _TclBN_mp_unsigned_bin_size • _Tcl_AttemptAlloc • _Tcl_GetObjResult • _Tcl_GetWideIntFromObj • _Tcl_NewListObj • _Tcl_ConditionNotify • _Tcl_NewBooleanObj • _Tcl_SplitList • _Tcl_EvalObjv • _Tcl_GetThreadData • _Tcl_GetVar2Ex • _Tcl_NewWideIntObj • _Tcl_NewBignumObj • _Tcl_ListObjGetElements • _Tcl_GetString • _Tcl_GetString • _Tcl_GetString The use of non-public or deprecated APIs is not permitted on the App Store, as they can lead to a poor user experience should these APIs change and are otherwise not supported on Apple platforms. I read online that this is a sort of a widespread issue right now with apps that embed Python (would share links but then my post will have to be approved by a moderator). Anyone have a workaround?

I was wondering if there is a quick way to convert a model trained with the open source CRFSuite for use with NLTagger? It seems like retraining should be possible but was wondering if automatic conversion was supported?

I'm using AVAudioEngine to play AVAudioPCMBuffers. I'd like to synchronize some events with the playback. For example if the audio's frame position is >= some point && less than some point trigger some code. So I'm looking at - (void)installTapOnBus:(AVAudioNodeBus)bus bufferSize:(AVAudioFrameCount)bufferSize format:(AVAudioFormat * __nullable)format block:(AVAudioNodeTapBlock)tapBlock; Now I have frame positions calculated (predetermined before audio is scheduled I already made all necessary computations) . So I just need to fire code at certain points during playback: [playerNode installTapOnBus:bus bufferSize:bufferSize format:format block:^(AVAudioPCMBuffer * _Nonnull buffer, AVAudioTime * _Nonnull when) { //Inspect current audio here and fire... }]; [playerNode scheduleBuffer:fullbuffer atTime:startTime options:0 completionCallbackType:AVAudioPlayerNodeCompletionDataPlayedBack completionHandler:^(AVAudioPlayerNodeCompletionCallbackType callbackType) { // some code is here, not important to this question. }]; The problem I'm having is figuring out at what point in full buffer I'm at within the tap block. The tap block passes chunks (not the full audio buffer). I tried using the when parameter of the block to calculate the frame position relative to the entire audio but have be unsuccessful so far. I'm assuming the when parameter is relative to the buffer passed in the tap block (not my entire audio buffer I scheduled). Not installing a tap and just using a timer before scheduling my fullBuffer has given me good results but I'd rather avoid using a timer if possible and use sample time.

Configuration: I have a NSTextField (multiline) inside an NSWindow. I have another NSTextField (single line) inside an NSBox (which is in the same window). The multiline text field is first responder and is editing. I click on the single line text field inside the NSBox to edit that one. The NSWindow just closes. This is on Sonoma 14.2.1. I subclassed NSWindow and override the close method and put a breakpoint. Here's the call stack that leads to the window suddenly closing: #1 0x0000000189c73d90 in -[NSWindow __close] () #2 0x000000032343 in -[NSApplication(NSResponder) sendAction:to:from:] () #3 0x0000000189b543ac in -[NSControl sendAction:to:] () #4 0x0000000189b542f0 in __26-[NSCell _sendActionFrom:]_block_invoke () #5 0x0000000189b54218 in -[NSCell _sendActionFrom:] () #6 0x0000000189b5413c in -[NSButtonCell _sendActionFrom:] () #7 0x0000000189c4c508 in __29-[NSButtonCell performClick:]_block_invoke () #8 0x0000000189c4c264 in -[NSButtonCell performClick:] () #9 0x0000000189b545a8 in -[NSApplication(NSResponder) sendAction:to:from:] () #10 0x0000000189b543ac in -[NSControl sendAction:to:] () #11 0x0000000189befb48 in -[NSTextField textDidEndEditing:] () #12 0x0000000__CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ () #13 0x000000018625c65c in ___CFXRegistrationPost_block_invoke () #14 0x000000018625c5a4 in _CFXRegistrationPost () #15 0x00000001861971dc in _CFXNotificationPost () #16 0x0000000187289ff0 in -[NSNotificationCenter postNotificationName:object:userInfo:] () #17 0x0000000189bef754 in -[NSTextView(NSSharing) resignFirstResponder] () #18 0x0000000189a9fab8 in -[NSWindow _realMakeFirstResponder:] () #19 0x0000000189b4f18c in -[NSWindow(NSEventRouting) _handleMouseDownEvent:isDelayedEvent:] () #20 0x0000000189ada79c in -[NSWindow(NSEventRouting) _reallySendEvent:isDelayedEvent:] () #21 0x0000000189ada45c in -[NSWindow(NSEventRouting) sendEvent:] () #22 0x000000018a1879f4 in -[NSApplication(NSEventRouting) sendEvent:] () #23 0x0000000189dd6908 in -[NSApplication _handleEvent:] () #24 0x00000001899a1d74 in -[NSApplication run] () The mouse click is no where near the close button in the title bar.

I have a PCM audio buffer (AVAudioPCMFormatInt16). When I try to play it using AVPlayerNode / AVAudioEngine an exception is thrown: "[[busArray objectAtIndexedSubscript:(NSUInteger)element] setFormat:format error:&nsErr]: returned false, error Error Domain=NSOSStatusErrorDomain Code=-10868 (related thread https://forums.developer.apple.com/forums/thread/700497?answerId=780530022#780530022) If I convert the buffer to AVAudioPCMFormatFloat32 playback works. My questions are: Does AVAudioEngine / AVPlayerNode require AVAudioPCMBuffer to be in the Float32 format? Is there a way I can configure it to accept another format instead for my application? If 1 is YES is this documented anywhere? If 1 is YES is this required format subject to change at any point? Thanks! I was looking to watch the "AVAudioEngine in Practice" session video from WWDC 2014 but I can't find it anywhere (https://forums.developer.apple.com/forums/thread/747008).

I'm looking for the AVAudioEngine in Practice video from WWDC 2014 (session 502) but can't seem to find it anywhere. Does anyone have a link to this session video? I can only find the slides. Thanks.

I just tried submitting an app to be notarized. This app is actually only used by me internally (but I have other apps this question would be relevant to) and I can't submit for notarization. I get the following error: "Hardened Runtime is not enabled." Is the Hardened Runtime now required? I know it used to be optional (I believe the last time I submitted an app update a few months ago outside the Mac App Store I got no such error).

For awhile I've wrapped OSLog in my own macros to include the line number and source file the logging statement originates from in debug mode because OSLog didn't include that info in console output (until recently). Now I noticed the source code file and line number of the logging statement isn't being shown (I have all the metadata switches turned on in Xcode's console "Metadata Options" popover). Then I realized it is being shown, only on mouse hover over the logging statement in very tiny text. The text is barely readable (on mouse hover). Why would viewing the line number require me to move the mouse cursor over a logging statement? It doesn't look pretty at all (hiding information behind mouse hover) and even if it did look pretty, this is the console for programmers and we don't care about such nonsense.

Is there a way to link a prebuilt dylib that was built for the 'macOS' platform on Mac Catalyst without being warned by Xcode? Generally it would be better to just recompile for Mac Catalyst but this is a third party library and they have a complicated build system with dozens of dependencies that doesn't support Mac Catalyst as of now (although they have iOS and Mac 'regular'). So I would have to spend quite a bit of time trying to sort through their build system to make a Catalyst version myself. The library uses no platform specific UI code and I'm fairly certain that macOS build would work just fine on Mac Catalyst without any changes since it isn't UI related at all. It seems to work fine (apart from Xcode warning me about linking a .dylib built for macOS on Mac Catalyst). I could shim all this away in a NSBundle that is aware of the AppKit world but then I have to make all method calls to the third party framework on Mac Catalyst through the bundle and it would separate my iOS and Catalyst code relying on the same implementation which isn't great. Is there a way I could just replace the 'macOS' platform in the .dylib with macCatalyst to get rid of the warning?

I'm trying to convert a PyTorch forward Transformer model to CoreML but am running into several issues, like these errors: "For mlprogram, inputs with infinite upper_bound is not allowed. Please set upper. bound" 570 • to a positive value in "RangeDim)" for the "inputs" param in ct.convert().' raise NotImplementedError ( 259 "inplace_ops pass doesn't yet support append op inside conditional" Are there any more samples besides https://developer.apple.com/videos/play/tech-talks/10154 The sample in that video an imageType is used as input but in my model text is the input (and the output). I also get warned that converting "torch script" is experimental but in the video it says it a torch script is required to convert (though I know the video is a few years old).

I'm aware signing in to an Apple ID on a macOS Virtual Machine is not supported, unfortunately. But is there a way to download Xcode from within the VM? I know the developer website used to have links where you could directly download Xcode outside the Mac App Store but I can't seem to find it?

I have a global variable in WKUserScript declared as a const in Javascript. I load this script in a custom WKContentWorld I create with my own name (not the pageWorld or default world). There some nasty javascript out there on most popular sites. I noticed that unhandled errors on the page can break stop my WKUserScript from working. In one particular case there is this nasty script on page for ads that uses document.write like so: b.contentWindow.document.write(e), b.contentWindow.document.close() And the web inspector shows an error here "Can't create duplicate variable: 'MyGlobalVariableNameInsMyUserScriptHere'" This script being used on the web page is going to end up getting blocked. But my question is this, isn't using my own content world supposed to protect me against this type of thing? This global javascript variable (an array) is global in my javascript file and holds some data in it but it is not inserted into the DOM. Shouldn't document.write/document.close calls from the page not cause this type of error in my user script? And if the entire DOM is being rewritten shouldn't a new script (representing my user script) be created from scratch? I think I can avoid the error by changing the variable from const to var (haven't tried yet). But is this how it's supposed to be?

I see the -resumeAllMediaPlayback: says the replacement method is -setAllMediaPlaybackSuspended:completionHandler: I don't believe suspending and resuming media playback are matching actions, which would mean -resumeAllMediaPlayback: doesn't have a replacement API? The deprecated -resumeAllMediaPlayback: method doesn't seem to work on Sonoma (pauseAllMediaPlaybackWithCompletionHandler: does work but resume does not).

So I have a WKWebView with a loaded page. This page is playing an embedded Youtube video. The playback state is WKMediaPlaybackStatePlaying. All good. Then I click a link on the page (navigation jumps to a new page) and the video is no longer playing. No video or audio. The navigationDelegate calls -webView:didFinishNavigation: And my navigationDelegate call -requestMediaPlaybackStateWithCompletionHandler: on the webview from within -webView:didFinishNavigation: And in the completion handler of -requestMediaPlaybackStateWithCompletionHandler: the playback state is WKMediaPlaybackStatePlaying but nothing is playing because we are on a new page.... I even tried calling -requestMediaPlaybackStateWithCompletionHandler: after a delay but that doesn't seem to make a difference (even gave it a delay as long as 5 seconds)
