hello, has anyone seen a feature in the Callkit SDK where one can add an audio input (such as from an MP3 file) into an ongoing voice call? e.g. mix a playing audio file into the microphone audio (or, possibly, mix it to one channel like MP3 file gain = 1 (max), mic = 0) so the audio only comes from the MP3 file?

Can anyone from apple provide the spline formulation that is used in the CIToneCurve filter?The documentation says that a spline is passed thru the points you give it, but thereare a lot of spline types in the world, and they all can yield different shapes thru the same set of points.

aside from the beta-test type of promo codes, is there any way to have "reduced price" promo codes that are used via the Redeem feature in the app store, for either full apps or in-app purchases (possibly subscriptions)?

Can anyone clarify which devices or chips the so-called "neural engine" can be used for machine learning model Training? As opposed to inference (or prediction)? And can external libraries such as Tensorflow (perhaps via the browser-based javascript library) access the neural engine in any manner for training or inference?

does anyone know if the mac app store ranking system has changed recently for mac apps? my mac apps have dropped like a proverbial rock in the ranking system near the end of last week. has any one done any experiments to see if mac app store rankings are higher if you recompile your apps for M1 apple silicon systems?

hi all, trying to create an imessage extension example based upon the Hello World story board that shows up when you create the extension. if i add a button to the hello world story board, and hook up the button to a method, i dont seem to be getting any tap events on that button. i tried also creating a button manually with [UIButton buttonWithType] and adding a target to it...the buttons show up, but they don't take tap events. i used the UI examiner in xcode, and touch events seem to be enabled on all views in the imsg extension view stack. i do see a strange message in the xcode console which i havent seen before: [PPT] Error creating the CFMessagePort needed to communicate with PPT. any ideas? PS: this is on simulator. i tried on device, same behavior. no touch events.

how is this secure? i have to switch icloud off and on for testing icloud in apps, and everytime i do this, it vacuums up all my photos and puts them on the cloud.

i pushed a couple of builds up to app store connect on dec5 and they just disappeared. not showing as in-process or anything. anyone else see this happening?

i am getting this error when i added a new app extension (notification content) error: Embedded binary's bundle identifier is not prefixed with the parent app's bundle identifier. Embedded Binary Bundle Identifier: (null) i have set it up the same way as another app extension in the app. i have also tried to set the bundle id manually in the info.plist file as noted by some posts, but xcode keeps changing it back to the default of ${PRODUCT_BUNDLE_IDENTIFIER}. e.g. my manual edits to info.plist aren't being accepted for this key. it seems like maybe PRODUCT_BUNDLE_IDENTIFIER variable is getting cleared to null for that extension during the build process? any workarounds?

my understanding is that header file search paths (-I options) go directly to the compiler command lines. so: why when i switch to the new build system am i suddenly getting header file path errors (cant find various header files)? does any one have any documentation on how the new build system affects the header file search paths?

does anyone know if the CreateML app has a way to build Support Vector Machine models for tabular regression? I see only the attached options. xcode14.2

hi all, is it possible to control the orientation of the UIMenuController popup menu or does it always follow the status bar orientation like so many other things do? see attached. main app is in portrait but some uses are in a landscape mode. but the status bar is still portrait in this case. so we would like to force rotate the popup menu to be in landscape mode.

do any of the new metrics tools allow the developers to detect app uninstalls per user? business clients are requesting this.

hi all, I am trying NSKeyedArchiver to archive an ObjC object. is it possible to specify a particular @property of the class that is to archived so that the @property is not put into the archive? or just put it into the archive as nil or something innocuous like NSNull or something. e.g. i have a uidelegate @property in my class, but i dont want that put into the archive i guess i could nil this out manually before archiving, but i wonder if anyone knows a cool trick for this
