[Swift] Either require semicolons or don't
This is admittedly a bit of a nit, but the current rules for semicolons in Swift are going to lead to ugly, inconsistent code. Semicolons should either be required between every statement, or disallowed entirely with the one exception of having multiple statements on a single line.
For whatever it’s worth, my preference would be to remove the semicolon entirely and disallow having multiple statements on a single line. There are few, if any, circumstances where having multiple statements on a single line improves code in any way.
Steps to Reproduce
Xcode 6 Beta 1
