Change BPM value of Spotify Song Swift about spotifylogin

[tomaculum]

Hi shamdass,
This is a framework for authenticating with the Spotify API and not a Web API wrapper.
The audio features endpoint only allows GET requests therefore it is not possible to override the BPM (tempo) values provided by Spotify.
If there is something wrong with the way the tempo values are calculated, please open an issue in the dedicated Web API repository.

Hello @tomaculum,
Thank you for your reply. I know this is a framework for authenticating with the Spotify API and not a Web API wrapper. but i have little confusion if there is only GET only property then some other application's change Spotify BPM. Is there any special paid service provided by Spotify ya any third party doing this?

Do you want to change the tempo attribute of the web API or change the playback speed on your device?
Unfortunately I don’t know if there is such a paid service or any third party provider.

Yes, I want to change playback speed of Spotify Song. Is there any way or any web API through change playback speed of Spotify song.

If there is no way to change playback speed with the iOS-sdk, you need to modify the playback somehow on your device like probably override some methods of the playback classes.
This is clearly no issue with the Spotify Login framework, therefore please ask this question on stackoverflow with the spotify tag.

Thank you for your reply @tomaculum
Okay i will post this on Stackoverflow with the spotify tag. give me some suggestion how to change playback speed. Because I've tried to change or override playback classes but no results yet.
