false equals false !false equals NOT false, so true

! as prefix negates whats coming. in if statements you have for instance:

if valueOne != valueTwo {

}

In this example, the code will be executed if valueOne IS NOT equal to valueTwo

if valueOne == valueTwo {

}

In this example, the code will be executed if valueOne IS equal to valueTwo.

I hope this helps
