I have an app that implements the MediaPlayer framework. I can read the state, stop, play, skip, reverse, etc.

How can I update the BPM, or the comments, etc…

I have tried a direct assignment on MPMediaItemPropertyBeatsPerMinute and I get the error:

Read-only variable is not assignable

I currently have a UITextField for collecting user input, and a UIButton to save the data.

What methods can be implemented to save/push the data in the UITextField to the tracks MetaData.

Any leads would be great!
