Finally finished my macOS+iOS project.
Mac app which play your YouTube playlist while displaying changeable image next to the player with the workout you are doing. It has features like:
-saving workout details in calendar
-download the currently playing video
-remove song from current playlist and add it to playlist with Old songs
-save the remaining songs of the playlist shuffled to new playlist to listen to them from your phone while you take a bath after the workout for example
-the app detects three playlists based on the description:
      *”music” in description for Music playlist
      *”newest old” in description for Old songs playlist
      *”rest songs” in description for rest songs playlist(the songs you didn’t listened to from music playlist, this playlist is auto generated on exit if you want)
-the app can play any playlist or video from YouTube sent by the iOS app over tcp and add a song to your Music playlist if you liked it.

The iOS app features:
-gesture control for the main app over TCP
-chart for the weekly calorie burn retrieved from calendar.
