Hello, I am wondering how one can play music videos (with the actual video playing) with the ApplicationMusicPlayer using MusicKit for Swift? There is not much documentation on this, so any help would be appreciated.

If I make a request to https://api.music.apple.com/v1/storefronts/us with the proper developer jwt token in the header, I receive the a successful response with a list of store fronts. If I remove the token, I do get back a 401 error. If I call any other catalog base query, I am getting back a 500 error. For instance: https://api.music.apple.com/v1/catalog/us/albums/310730204 returns a 500 error with the body being {"message":"An unexpected error occurred"} I'm not sure what I can do to fix this. Please help.

Hi,Since today, we are no more able to do DELETE/PUT request on the Apple Music API.So, we can't update a playlist details, delete a playlist, delete tracks in playlist, delete tracks in library...Old methods allowed are now returning only an HTTP Code 403.Why this change in the Apple Music API ? We can hope that will be back soon ?

When I use the ColorSync Utility to convert Display P3 color (1, 0, 0) to an XYZ color, the result is (0.5151, 0.2412, -0.0011). I expected that result because that is identical to the red colorant tristimulus value in the Display P3.icc file.When I use the CGColor converted method to do the same, the XYZ color is approximately (0.5151, 0.2412, 0.0). Note that the third element is 0.0 whereas it is -0.0011 when using the ColorSync Utility. I have printed out the Z component to 16 digits of precision, and Z is all 0s. It appears that the CGColor converted method is clamping the result from 0 to 1.My questions are:1. Which conversion is correct? The ColorSync utility or the CGColor converted method?2. I am not a color specialist, but I thought that the XYZ components should never be negative. If so, is the colorant tristimulus value in the Display P3.icc file wrong?3. Because CGColor clamped the Z component to 0, the XYZ color cannot be converted back exactly or closely to the Display P3 color (1, 0, 0). I would have expected to be able to go back and forth between the two color spaces when starting from a valid P3 Display color especially since the XYZ color space completely encompasses the P3 Display color space. Is that not true?4. Is (1, 0, 0) an invalid Display P3 color? If so, I can understand the peculiar results. I'm not sure how I would know if a Display P3 color is valid or not. (I only know that the component values must be from 0 to 1.) I think it is valid because Apple uses that color in the UIColor API Reference in an example.
