Pass data between view controllers

Question

i'm trying to pass data between viewcontrollers with value is slider's value but it's not work. here's my code ViewController1

Also you need to pass String instead of slider value `performSegue(withIdentifier: "dataPass2", sender: simpleString)`. — Nirav D, Sep 24 '16 at 09:35

After looking at your screen shot, I would suggest you to assign simpleString value to destination.myString.

Your code will always fail because you are trying to cast from a Double to a String. Doing this in Swift gives the following message:

Cast from 'Double' to unrelated type 'String' always fails

What you need to do is have the line of code changed from:

 destination.myString = sender as? String

to:

 destination.myString = String(format:"%f", sender)

or

 destination.myString = "\(sender)"
