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.

as i am typing in a Terminal window on Catalina (as all developers must do), i must be accidentally hitting some secret pattern of keys, because yellow man page windows keep popping up to do a "man" command on whatever word i am typing. how do we shut this terrible feature off?

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?

we used to use code such as this to make sure the keyboard comes up in a desired orientation [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO]; however, apple has no-op'd setStatusBarOrientation: it still can be called, but it gives a warning that it no longer does anything as of iOS13 does anyone know the recommended replacement path for this feature?

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)"}}

as in the above note, shorter videos, say, less than 1 hour playing time seem to export ok. this is just a time clip operation we are doing not a composition. but when we put videos longer than an hour and try to clip them to an hour, the export fails part way thru we can see the .progress property proceeding then we get the mysterious unknown error code: An unknown error occurred (-12551) as noted below in our console output apple any hints besides unknown? surely your code knows why it failed. why not tell us?! the "code = " listed below is the .status which shows as 4 waiting for trimmed movie file save 1 progress = 0.692948 2021-03-08 14:55:52.702278-0500 KargoCamera[1598:154227] Export failed: The operation could not be completed code = 4 2021-03-08 14:55:52.702412-0500 KargoCamera[1598:154227] Export recovidea: (null) 2021-03-08 14:55:52.702507-0500 KargoCamera[1598:154227] Export reason: An unknown error occurred (-12551)

previously (last year) I was able to generate provision profiles that matched to the *.maccatalyst.*com.* bundle id pattern. now when i try to generate a new mac provision profile because my prior profile expired, this site generates the profile for the iPad version of the bundle id pattern. e.g. without the .maccatalyst. portion of the bundle id. this is not usable for code signing of the mac app since the bundle id does not match. what is going on with this?

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?
