Classification:Enhancement Reproducible:Not Applicable
 
Summary:

This simple code should work out of the box. If == works, != should work too.

=====

/* why asymmetric testing for nil equality with implictly unwrapped optionals? */
let mystr :String! = "hello"
let testIsNotNil :Bool = (mystr != nil)
let testIsNil :Bool = (mystr == nil) // error
