I have a NSWindow subclass. The window has a custom shape, and thus has a custom contentView which overrides drawRect to draw . Since the window has a custom shape it cannot use the system provided titlebar. The problem I'm having is when there are multiple screens, if my window is on the inactive screen (not mainScreen with menu bar) and I move the mouse over to the second monitor and click the window....the menu bar doesn't travel to the screen my app is on after the window is clicked. This does not happen with any other window. In all other windows, the menu bar moves to the screen once you click a window on that screen. So it appears this is because my window is not using NSWindowStyleMaskTitled. As far as I know, I can't use the system title bar and draw my custom window shape. Abandoning the custom window shape is not an option. Without going into too many details as to why I care, the menu bar really should travel with first click on my window like other apps.. Is there a way to tell the system (other than using the NSWindowStyleMaskTitled) that clicking on my window should make that screen the "main screen" (bring the menu bar over? I tried programmatically activating the application, ordering the window to the front, etc. but none of this works. This forces the user to click outside my app window, say on the desktop, to move the menu bar over, which feels wrong. Thanks in advance if anyone has any suggestions.

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.

I can’t submit an App Update without providing the EU trader information. I keep trying to submit this information. I upload all the documents, go through all the steps, then at the end I get the following error message: “Something went wrong. Please try again.” This is pretty frustrating. Then I had to start over...did it all again and ended up with the exact same error message. So I'm blocked from updating an app today...any advice on how I should proceed?

I tried redeeming a promo code for a subscription on iOS 18. It's a yearly subscription (the promo code is for myself in this case). This always worked before. Now on iOS 18 when I redeem the code in the App Store it just spins an activity indicator in the navigation bar for a few seconds and stops. Promo code doesn't redeem. No error message either. Now when I try to redeem the promo code on the Mac App Store I get the following error: "You must redeem this code on a device that supports App name". This error makes sense because the app is iOS/iPadOS only. But the fact that the Mac App Store displays the App name in the error message indicates that the code is valid and should work on iOS, but it does not.

I've been putting off entering my EU "trader status" info. I see this is published on the developer site: "Starting October 16, 2024, developers must provide their trader status to submit new apps or app updates for distribution in the European Union. To comply with the Digital Services Act, go to the Business section by February 17, 2025 to provide your trader status or your app will be removed from the App Store in the EU." So do I have to do this now (today October 16, 2024) to prevent my apps from being removed from the EU App Store (or do I have until February 17, 2025)?

My app, which has been on the Mac App Store for many years, has an update being blocked by App review. The only change made is a bug fix (documented in the release notes). First rejection: Said I was using an entitlement I didn't need. My response: I explained the feature that required the entitlement. App goes back in review and gets rejected again for completely different reasons. They don't want me to write files in my App Sandbox container and instead write them in a more traditional user facing location (like in the Documents folder). They keep sending me a link to the "App Sandbox Design Guide" in the Documentation Archive (which appears to redirect to a different page?) and are quoting a section that is nowhere to be found in the link they send me (on the page I'm redirected to). I keep explaining to them that I cannot write outside my sandbox container and that this isn't my choice. And they keep rejecting my app and sending me a broken link to the "App Sandbox design guide." It isn't my fault that I have to write to my sandboxed container by default or have a non-functioning app. In any case, I don't understand why a bug fix update is being held up and I'm getting some vague instructions about possibly having to design some long winded explanation to the user in some ridiculously complicated onboarding process about choosing a folder in a save panel, why you have to choose the folder in the save panel (because I need your permission), OR just quit the app you just bought because it'll otherwise do nothing if you don't choose a folder in the save panel. Users got enough panels to deal with. At the very least App review shouldn't send me broken links from the Documentation Archive. So I'm using my sandbox container by default (because by default I cannot do anything else). I've been doing this for a long time and I don't understand why it is suddenly a problem. What is my sandboxed container for if I can't write to it? If documentation such as the "App Sandbox Design Guide" is still relevant and important why is it being archived anyway ? The link redirects I cannot find the section the reviewer is citing in the provided link. I don't mind being asked to do something to improve the app but I've wasted a lot of time trying to satisfy app review in the past only to misinterpret what they actually are asking me to do causing more wasted time and energy and not getting a whole lot in return. And I don't think it's fair to block a bug fix update.

I'm trying to create a dynamic menu on Mac Catalyst. Using a UIBarButtonitem like so to make a "pull down" button: UIDeferredMenuElement *deferredmenuElement; deferredmenuElement = [UIDeferredMenuElement elementWithUncachedProvider:^(void (^ _Nonnull completion)(NSArray<UIMenuElement *> * _Nonnull)) { UIAction *actionOne = [UIAction actionWithTitle:@"Action One" image:nil identifier:nil handler:^(__kindof UIAction * _Nonnull action) { NSLog(@"action one fired."); }]; UIAction *actionTwo = [UIAction actionWithTitle:@"Action Two" image:nil identifier:nil handler:^(__kindof UIAction * _Nonnull action) { NSLog(@"action two fired."); }]; UIAction *actionThree = [UIAction actionWithTitle:@"Action Three" image:nil identifier:nil handler:^(__kindof UIAction * _Nonnull action) { NSLog(@"action three fired."); }]; completion(@[actionOne,actionTwo,actionThree]); }]; UIMenu *wrappedMenu = [UIMenu menuWithChildren:@[deferredmenuElement]]; UIBarButtonItem *uiBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:nil menu:wrappedMenu]; uiBarButtonItem.image = [UIImage systemImageNamed:@"rectangle.and.pencil.and.ellipsis"]; self.navigationItem.rightBarButtonItems = @[uiBarButtonItem]; The button appears in the toolbar but when I click it to expose the menu I get a menu with on element in it that says "Loading...". The the uncached provider block is never called. Running Ventura 13.2.1 and Xcode 14.2.

So with SKStoreReviewController now deprecated... I'm wondering what API is recommended for UIKit apps?

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 just upgraded to iOS 17 and it looks like AVSpeechSynthesizer is now broken. I noticed when feeding certain strings to AVSpeechUtterance it just dies flat out stops after only speaking a portion of the string. For example I fed it a string of approx. 1200 words and it speaks up to around 300 words or so and then just stops. The synthesizer delegate method -speechSynthesizer:didFinishSpeechUtterance: is called when this happens, as if this is supposed to be the end even though it is not even close to being finishes. Was working fine on iOS 16. FWIW I create the AVSpeechUtterance with -initWithString:

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.

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).

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.
