Swift 3 Convert Double to String

Question

I keep getting this error. “The initializer for the conditional binding must be of an optional type, not“ Double. ”I am trying to display some basic data data, and this is double. Ive tried to get around this the same way I had to do to save the values ​​when converting it.

heres code that gives me an error:

func displayStats() { // display other attributes if they have values if let servingSize = mealstats.serving { servingsLabel.text = servingSize } 

Answer 1

foodstats.serving is likely to be of type "Double" and not "Double?"
Since it is not optional, it cannot be deployed. The correct way to use it is

 func displayStats() { // display other attributes if they have values servingsLabel.text = "\(mealstats.serving)" }
