I agree with @Afogh! I think this should be fixed ASAP.

I agree. I think they should make it clear what are we supposed to do.

This worked for me! Thanks!

My workaround is to manually adjust the step value. It works but you have to do some bookkeeping and requires maintenance.

Thank you for the comprehensive reply. I think instead of isInteracting you can try and use slider.isTracking property. I still think this is something Apple should fix themselves.

This does not always work. Sometimes I get notified in the following order: didEndOrCancel -> valueDidChange -> didBegin; You can try and reproduce it when you touch the slider and release it. I should note that I'm using the system thumb image not a custom one.

After I wrote the issue I fallback to beta 4. Today I tried again with beta 5 and the issue was fixed. So I think you can cleanup some Xcode files and try again on a clean slate.
