iOS Developer here. Personally, I am not a fan mostly because I find vertical scrolling/swiping to be much better as faster than horizontal scrolling in your case. The default iOS pickers use the vertical way and I find it to be much better UX. Design wise, yours does look much nicer though so kudos to that!
