I have multiple users of an app complaining that they are not able to download (on older device) the latest version of an app compatible with the device. This used to be automatic then, some years ago, it changed to work only if the user tries to download the app from the "purchased" section of the App Store app. Now it seems to be gone. Is that actually true or I have a set of specially dumb users? 🙂 Do anyone (or Apple) have any final word on the current availability of this feature? (the ability to download the latest version compatible with the device) Thank you in advance!

I have a Catalyst application that uses (as expected) MPNowPlayingInfoCenter to set the now playing info and MPRemoteCommandCenter to get the media events for play/pause/stop/favorite/etc. The code is shared on iOS, tvOS and watchOS and it works correctly there. It seems not to work on macOS (app is compiled as a Catalyst application) on Big Sur (and Monterey, fwiw). Media keys on the keyboard starts the Music app, the music part of the control center do not show now playing info (nor the media controls there send messages to the app). I seem to remember that it used to work in Catalina (at least the media key part) and for sure it used to work in a precedent version of the same app that used to be an UIKit one. Is this a bug (worth a feedback to Apple) or something wrong on my side? I forgot some magic capability for macOS? App is sandboxed and uses hardened runtime, in case this is significant. Thank you for any hint!

I have an application that works on both iOS and OS X (as normal UIKit and AppKit applications). Now, I rewrote the app to accomodate a very significant backend change and now I'd like to avoid rewrite the UI on AppKit but just use the iPad app with Catalyst.The problem is: the generated bundle-id for Catalyst app is on the form uikitformac.ios.bunde.id, can I change it to the existing Mac bundle ID so I can market it as an update to the previous app, that's what actually is?Also, the iOS app uses CarPlay (audio) so I must use custom certificates (they cannot be managed by Xcode with CarPlay entitlements), can I manually generate the mac certificates for the catalyst app? I tried with Xcode beta 3 (or 4) and I didn't manage to do anything.It's what I want to do even possible?Thanks in advance for any information!

Subject says basically all. I have a CarPlay audio app whose network accesses (started answering playableContentManager(_:,initiatePlaybackOfContentItemAt:, completionHandler:)) fails when the application is started from the CarPlay screen with the phone locked.All calls are https; no data protection active; the app works correctly when cached content is played (ie: it's the network access that fails); the app works correctly if the phone is unlocked.I'd say this started around iOS12 (I'm not sure, though)... it was working when I started implementing CarPlay (~iOS10).I cannot find any documentation for the behaviour. Is this expected (and there is some workaround) or should I file a bug against CarPlay?Thank you in advance!

This is on Xcode Version 7.3.1 (7D1014) on OS X 10.11.5 (15F34), target is an iOS application, built for iOS 9.I have an audio application in which I cannot manage to show the cover art in Now Playing lock screen.I can show a static image and other information but I'm not able to show the "real" album cover. Code below works correctly (a 512x512 image is displayed: NSMutableDictionary __block *mpInfo = [[NSMutableDictionary alloc] initWithDictionary:[[MPNowPlayingInfoCenter defaultCenter] nowPlayingInfo]]; mpInfo[MPMediaItemPropertyArtist] = currentSong.artist; mpInfo[MPMediaItemPropertyTitle] = currentSong.title; if([[RP4RadioManager sharedManager] isPlaying]) { mpInfo[MPNowPlayingInfoPropertyPlaybackRate] = @(1.0); } else { mpInfo[MPNowPlayingInfoPropertyPlaybackRate] = @(0.0); } mpInfo[MPMediaItemPropertyPlaybackDuration] = @([currentSong.duration doubleValue] / 1000.0); mpInfo[MPNowPlayingInfoPropertyElapsedPlaybackTime] = @(0); mpInfo[MPMediaItemPropertyArtwork] = [[MPMediaItemArtwork alloc] initWithImage:[UIImage imageNamed:@"BigLogo"]]; [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:mpInfo];some rows below I recover the cover art from the network and I try to show it: coverImage = [[UIImage alloc] initWithCIImage:currentSong.coverImage]; MPMediaItemArtwork *imageArtwork = [[MPMediaItemArtwork alloc] initWithImage:coverImage]; mpInfo[MPMediaItemPropertyArtwork] = imageArtwork; DLog(@"Setting cover info. Image: %@, imageArtwork: %@ (%@). mpInfo: %@", coverImage, imageArtwork, NSStringFromCGRect(imageArtwork.bounds), mpInfo); dispatch_async(dispatch_get_main_queue(), ^{ [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:mpInfo]; });The image is valid (usually 500x500px, but this don't seems significant). The image is originally a .jpg, saved in a CIImage (for OS X comaptibility in common code) and then loaded in a UIImage (the same image shows correctly in a UIImageView).Changing the linempInfo[MPMediaItemPropertyArtwork] = imageArtwork;withmpInfo[MPMediaItemPropertyArtwork] = [[MPMediaItemArtwork alloc] initWithImage:[UIImage imageNamed:@"no_cover"]];shows a different static image, so the problem is in the original image but I really cannot understand what the problem is... the log line shows an image and a valid MPMeidaItemArtworkSetting cover info. Image: <UIImage: 0x14eaeed0>, {500, 500}, imageArtwork: <MPMediaItemArtwork: 0x14eaef00> ({{0, 0}, {500, 500}}). mpInfo: { MPNowPlayingInfoPropertyElapsedPlaybackTime = 0; MPNowPlayingInfoPropertyPlaybackRate = 1; albumTitle = "Radio Paradise"; artist = "Other Lives"; artwork = "<MPMediaItemArtwork: 0x14eaef00>"; playbackDuration = "242.8"; title = "Tamer Animals"; }I suspect it's something really stupid but I don't really know how to debug that.Any help/hint will be appreciated.

I'm trying to add myself to a "internal testers" testflight build. When I tap the "start testing" link in the email, Testflight (the app) opens on the app page. Tapping "install" returns an alert box telling "Couln't accept the invite", "Invite for this app already accepted" (the second translated back from Italian, it's translated in the app).The app don't appears in "Testing", there is no (apparent) way to start the test. The same appens on other devices of mine. I already tried to remove me from the internal testers list and readd me later with no results.Any ideas/hints/suggestions?Thank you!
