I often find when doing basic actions in MusicKit it is incredibly slow compared to Apple's Music App. I've tried different versions, devices, networks, Apple's sample code, it all throughout the last several years, and it is all the same. Does anyone else have this issue?

I can't seem to find an album using MusicKit containing RecordLabel. I am using album.with([..., .recordLabels, ...] but I only see an empty recordLabels collection returned for every album I am trying... Is this actually available / populated through MusicKit?

Hello, I am working on the Musickit web browser application. I have created my developer token as mentioned in the documentation. When I call the authorize() method to authenticate, I get the Apple Music pop up as expected. However, after entering the user credentials and "allowing" access, I get the following error: POST https://play.itunes.apple.com/WebObjects/MZPlay.woa/wa/webPlayerLogout 403 (Forbidden) musickit.js:28 Uncaught (in promise) AUTHORIZATION_ERROR: Unauthorized at https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:269512 at Generator.next () at asyncGeneratorStep$u (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:266594) at _next (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:266821) I am using an user account with paid subscription to Apple Music. With the JWT created, I am able to make API calls and receive the response for requests that do that need the userToken. I am currently stuck at this step and would like some help to root cause this issue.

How to extract an object from a picture or remove the background of an object just like you can create stickers in Photos app. Is there any other official model or library other than using some website's API? (DeepLabV3.mlmodel cannot infer what I need)

Is there any way to play panoramic or 360 videos in an immersive space, without using VideoMaterial on a sphere? I've tried using local videos with 4k and 8k quality and all of them look pixelated using this approach. I tried both simulator as well as the real device, and I can't ever get a high-quality playback. If the video is played on a regular 2D player, on the other hand, it shows the expected quality.

Hello, I don't run a podcast, therefore, I am not referring to the apple podcasts connect platform, and have been trying to get in contact with someone at Apple Podcasts. I would like to talk to developer support or someone who could consult on how to best approach something i'd like to build as an open source tool. I listen to a lot of podcasts and would like an analytics dashboard and toolset to take notes from the podcasts that I listen to on Apple Podcasts. Although, it would be just a good start to have analytics, accessing all of the info. I need to be able to plug into an API and pull all of that data from my account. Is there any way I can access this or talk to someone about this? I have a lot of historical data I assume from all of the shows i'm subscribed to and would like to visualize all of this. Is this possible? From my research, it seems that there is no way to access the information from the Podcasts app? Is there any infra for this?

I am currently experimenting with the MusicKit API, specifically if/how it could replace iTunesLibrary on macOS and MediaPlayer on iOS. My question is specifically about DRM-free tracks that the user has available locally (e.g. purchased, matched or uploaded tracks): Is there a way to access the on-disk URL of locally available and DRM-free tracks? In the iTunesLibrary framework on macOS there is ITLibMediaItem.location and on iOS I can get this path via MPMediaItem.assetURL, but MusicKit's Song.url seems to be nil for all of these tracks in my tests.

Hey there, I have been trying to add the ability for a user to edit the playback rate of a song in their Apple Music library to my application. I have found that whenever the playback rate is changed, the music pausing for about half a second. I was wondering what the cause of this issue is and if there is anyway around it. For context I am using the SystemMusicPlayer from MusicKit.

I can not find an album where isCompilation is true, even when the album clearly consists of "songs by various artists". For example: Album( id: "567979803", title: "Earth's Answer", artistName: "Brian Keane, Deuter, James Newton, ,...many more", isCompilation: false The compilation checkbox for this album in the Apple Music Catalog Get Info dialog is also not checked. Is this field NEVER SET in the catalog or the MusicKit API? If there IS an album where isCompilation is true, I'd like its ID to use for a test case. If not, can this be added to the API?

The MusicKit JS V3 documentation has this article about Native WebViews. For some reason, my app fails to do anything after musicKitInstance.authorize() is called. I think that it is not being recognized as a WebView and is trying to open the window as if it was running in a browser, but since it's not a browser, there's no way for it to open a browser window. Is there something I can do to make this work? I have tried many things, including setting the user agent to a few different ones for web views and seeing if it behaves differently but didn't see any different behavior. Is there something musickit.js checks for, when determining if it's running in a WebView, that I can leverage to ensure the Native WebView workflow is followed?

Hello, I have a music on apple music. When I search this music on Shazam, I want it to appear with a clip like the link I provided below. Is there any way you can help with this?

I have 3d image but when I insert iton my project its come without colors , any noe knows why?

I haven't found any really thorough documentation or guidance on the use of CIRAWFilter.linearSpaceFilter. The API documentation calls it An optional filter you can apply to the RAW image while it’s in linear space. Can someone provide insight into what this means and what the linear space filter is useful for? When would we use this linear space filter instead of a filter on the output of CIRAWFilter? Thank you.

Hello, I'm playing with the ScreenCaptureKit. My scenario is very basic: I capture frames and assign them to a CALayer to display in a view (for previewing) - basically what Apple's sample app does. I have two screens, and I capture only one of them, which has no app windows on it. And my app excludes itself from capture. So, when I place my app on the screen which is not being captured, I observe that most didOutputSampleBuffer calls receive frames with Idle status (which is expected for a screen which is not updating). However, if I bring my capturing app (which, to remind, is excluded from capture) to the captured screen, the frames start coming with Complete status (i.e. holding pixel buffers). And this is not what I expect - from capture perspective the screen is still not updating, as the app is excluded. The preview which the app displays proves that, showing empty desktop. So it seems like updates to a CALayer triggers screen capture frame regardless of the app being included or excluded. This looks like a bug to me, and can lead to noticable waste of resources and battery when frames are not just displayed on screen, but also processed somehow or/and sent over a network. Also, I'm observing another issue due to this behavior, where capture hangs when queueDepth is set to 3 in this same scenario (but I'll describe it separately). Please, advise if I should file a bug somewhere, or maybe there is a rational explanation of this behavior. Thank you
