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.

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)"}}

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.

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?

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.

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.

any one else having troubles uploading binaries to app store connect today? system status says all o.k.

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?

for those of you who have clients who are concerned with privacy, note that you have to go into system prefs in your mac and dig into the "siri suggestions and privacy" and shut off sirl for all the apps listed there, if in fact you don't want siri scanning your data. it is not enough to shut off "enable ask siri" at the top level. i found this out when siri scanned open safari pages and wanted to add things to my calendar. what? apple must have hired some google employees, heh.
