IOS 13

IS APDL ready for IOS13...

YES, but we have yet to get the final bits from Apple. If we find any issues of course we'll issue updates.
What about ipadOS?
Apple did not provide the "gold master" for that so I think initial release today may just be iOS 13 (for both iPhone and iPad), I'm not sure. This is the first year Apple missed the deadline so iOS 13 is actually incomplete. On September 30th they release iOS 13.1 which I think is the milestone they wanted for today, feature complete.
