Can I use an iphone/ipad with UR22?

I’m hoping some of you smart folks can confirm whether I can use my UR22 with an iPhone/iPad. I believe you can with the UR12 & UR 22 MK2 but I cant seem to definitively find the answer regarding the UR22. I was going to buy the Lightening to USB adapter but if it doesn’t work then I wont bother. If anyone can respond that would be very much appreciated. Thanks
