More elegant way to wait for a boolean to be 'true'

Question

I am a beginner in Swift, so this is how I wait for a boolean variable to be true:

while (boolVar == false) {}

I know that eventually, from another method, this variable will be set to true. Is there a better way to achieve the above? I'm not sure if that is the most elegant and/or efficient way.

Answer 1

The simple swifty way is to use didSet

var boolVar:Bool = false {
    didSet {
       if boolVar {
          // do job
       } 
    } 
}
