Yes, it's possible. I built Wrapping to make it easier.
...and I published some games and apps to Apple's app stores.
I got frustrated with Apple last year though, as there are many MANY issues to battle with. None of these projects are currently available.
Although, now that I wrapped up a massive (unrelated) project, I'm considering a return to Apple's app stores. I might bring back Wrapping, as it could help with the Hype 4... book... app... thing. There is one big issue that is stopping me...
I can't actually download files with the Wrapping / WKWebView method. 
It seems similar to the issue here... Link in iOS app not working any more - #22 by MarkHunte ...and I've been spending the past few days trying to figure out the problem. This seems the closest to a solution... ios - WKWebView does load resources from local document folder - Stack Overflow ...but it's not working for me.
I've been thinking about giving up, but there are a lot of people here that want me to continue with Wrapping and a new Hype 4 book. Also, I don't have any other "Photics" projects to work on right now. So, it feels like I should keep trying.
Again, it's possible. But, it's surprisingly difficult.
