Does iPad run on
macOS version 10.12 (Sierra), Mac OS X version 10.11 (El Capitan), or Mac OS X version 10.10 (Yosemite)
Or are you referring to the »companion apps«?
Not at this point. You still only can use the trimmed down "light" app variants on iOS like LR mobile and all that. Whether or not there wil lever be a full PS for tablets is anyone's guess.
I have been told that the new , June 2017, iPad Pro will support Photoshop CC
I wonder though who made the claim the OP refers to or if it was just a misunderstanding.
Supporting RAW files is an entirely different possibility. I am sure there are apps to support RAW files on the iPad. All iPad apps are of course in the app store, so searching is easy. There are not, and cannot be, any other apps not shown in the app store.
I believe there is some variant of Lightroom for Tablets. Of Course it will not be full Lightroom but most likely can do some RAW conversions with a Lightroom Develop Module type UI. I would be astounded if it could via a network connection import raw file into your Lightroom Library. I would think the a moble tablet Lightroom Output module would not have all the features found in Windows and OSX Lightroom versions. At best iPad Lightroom conversions can be use with PC and Mac versions of Photoshop, Lightroom, bridge etc.
CC Creative Cloud dose have some mobile tablet Apps.... iPad Phones IOS and Android apps...
I have been told that the new , June 2017, iPad Pro will support Photoshop CC, along with RAW files?
There has been no announcement of that. You might want to include a link to where you read that so that we can see what they really meant. Were you looking at the widely publicized demo of the new Affinity Photo for iPad during the iPad Pro announcement? If you want an iPad app that is the most like the desktop version of Photoshop, that's as close as you're going to get right now.
You should not buy an iPad Pro expecting to run the desktop version of Photoshop CC. Right now, the only way to run a full desktop version of Photoshop CC on a tablet is to buy a Microsoft Surface Pro tablet, because the Microsoft Windows operating system it uses can run the Windows desktop version of Photoshop CC. But you can't run the desktop version of Photoshop on an iPad, because iOS is too different from macOS.
On an iPad you can run the iOS apps Photoshop Fix, Photoshop Mix, Photoshop Express, and Photoshop Sketch, though none of them have all the features of the desktop version.
Raw file editing has been possible on the iPad for some time. Photoshop Express added raw file editing in 2014, I'm not sure about the others. Lightroom Mobile can import raw files from the iOS Camera Roll, edit them on an iPad, and sync the raw files and your edits through the Internet back to Lightroom on the desktop.
