Is it a Xcode bug?

Hi!

Does someone have an idea why Xcode seems to stop working when a result of an operator is false, but not in a way it returns "false", but in a logic sense if I can put it that way. For example, when I wrote:

let string1 = "Hello!"
let string2 = "Hello!"
let srting3 = "hello"

I get these results:

string1 == string2

true

string1 != string2

false

But when I changed them to:

string1 == string3

or

string1 != string3

the results on the preview fades and it seems to turn off any of another results in the preview. Have anybody faced similar problems with Xcode?

You spelled 'string' wrong in 'string3' in your declaration.

It should work fine after that. :)
