Why in Xcode there is error Popping up saying that enum case .some not found in type Page.Choice?
does Swift 4 made some changes to the enum .some and .none ? how should we find the changes if in swift 4 through documentation?

I'm not sure I understand your question. Swift 4(beta) isn't scheduled for release until later this fall (and hasn't been released early to my knowledge), so you are probably using Swift 3.
But without seeing all of your code / files, it is really difficult to help troubleshoot, otherwise.
If you could be more specific with what you are doing and the error you are receiving, plus posting your code (Please refer to the Markdown CheatSheet link below Post button for proper formatting of code blocks before posting) will help others be able to fully assist you.
Hopefully we can help you.
