Using S4 mk2 with Ipad? Sync? Midi Clock? Whats the best way?

Newbie here. Looking for the best way to send midi clock to ipad so that I can sync the ipad to the midi clock in traktor. Seems there could be many ways to achieve this. Special cable or mabye some type of app that supports midi clock on the ipad? Really teyinf to find a nice way to play beats from ipad to match traktor pros active track. Anyone out there with any insight please share. Im totally new to this and just playing in the home studio for now.

Seen apps like musicIO on the app. Sounds like maybe with the right app u could sync thru ur mac via lightning cable and then to traktor pro 2? Ableton live is not feasible at this stage.
