We are in an app review loop trying to get an in-app purchase approved with this message (below)However, we did what they said and resubmitted a binary (essentially the same binary we submitted before but witha new build number), but then the in-app purchase is rejected for the same reason, with no additional explanation.Is there a way to escalate this and talk to someone to figure what is going on? This is for a pre-existing app in the app store, not a new app.In-App Purchase - New Business ModelWe have begun the review of your in-app purchase but aren't able to continue because your submitted in-app purchases indicates a change of business model for your app. Therefore, we need to verify the implementation of your submitted in-app purchases in the app to ensure your app, and its in-app purchases, are in compliance with the App Store Review Guidelines.Next StepsPlease upload a new binary for review and resubmit your in-app purchase(s) with the binary so that we can continue the review.

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?

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.

We are using AVAssetWriter to write a movie file. All works fine, but when the app goes into the background and pauses operations, we would expect the writer to come back to life when you bring the app back into the foreground. However, it does not, it fails with this error code. Any hints, workarounds? Error Domain=AVFoundationErrorDomain Code=-11847 "Operation Interrupted" UserInfo={NSLocalizedRecoverySuggestion=Stop other operations and try again., NSLocalizedDescription=Operation Interrupted, NSUnderlyingError=0x2820356b0 {Error Domain=NSOSStatusErrorDomain Code=-16121 "(null)"}}

is it possible for other iOS apps to hold onto microphone access when those apps are in the background? we see some cases where our app cannot get mic access (e.g. we can record video but we get no sound) and we think it might be another app such as Telegram "holding onto" the mic, because when we quit all other apps, our app works ok. this seems like an odd failure mode. any hints how to fix it?

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 using the tabular regression method of CreateML. i see where it prints a couple of metrics such as root mean square error on the validation data, but i dont see any way to export the raw fitted numbers (e.g. training prediction), or validation numbers (e.g. validation prediction), or out of sample "testing" numbers (from the testing data set). is this possible in CreateML directly? the reason this is necessary is that you sometimes want to plot actual versus predicted and compute other metrics for regressions.

one of our testers got a new iphone13, hooray! but he cannot download apps in test flight anymore. the spinny thing shows then disappears. any ideas?
