I was able to upload “.app” to my device by following this youtube video
I hope XOJO team will be able to update their OLD video tutorial for deploying IOS app to the device using the latest procedure in current developer.apple.com website.
For those how tried to help me, thank you very much for the idea. I really help a lot on what to find.
Maybe my next trouble is how to upload and make it available in APPLE STORE.
