If I remember correctly, it means Not Equal To. But I may be confusing it with JavaScript...

thank you :D

That´s exactly what it means :) Any value of x != (is not equal) to a value of y with the same data type.

Glad I could help! It's been a while since I worked in Swift before switching tracks, so I hope I didn't confuse the two languages!

I confirm that != is a not equal operator , for e.g: 1 != 2 which really means 1 doesn't equal 2. Hope this helps : )

thank you :)
