Just a note for anyone passing this way. After some trouble I find that the order titles appear in .meteor/packages can be important. In my case, specifically touch punch must appear after jquery-ui.
e.g. in .meteor/packages
[…]
mizzao:jquery-ui
dsyko:jquery-ui-touch-punch
[…]
will work, the other way around (putting jquery-ui second), does not (no dragging on web).
Although, strangely I find it does work when built using XCode as a ios application, but not when the same app is deployed as a website and accessed via the same iPhone. Hope this helps save someone some time!
