Answer 1

Xcode is only an IDE you use. In general, an IDE could switch freely.
BUT with IOS development you always work against a Base SDK that defines the abilities of the apple frameworks.

Now Xcode 7 comes with IOS SDK 9
Xcode 6 comes with IOS SDK 8

---

So Switching between Versions of Xcode also switches the base sdk (unless otherwise configured)

---

--> your app may behave differently with different base sdks. If that is acceptable though OR you don't see any change THEN switching is no issue

I switch all the time :)

EDIT: just saw the swift 2 tag. That is not supported in Xcode 6 so you can't switch
