SOLVED: SOLVED: Xcode Playgrounds not showing live preview

Forums > 100 Days of SwiftUI
@zeldazeldajones  

Hi! I'm brand new to coding, and this is the first time I have used Xcode Playgrounds. The very first video in the 100 Days of SwiftUI tutorial shows that I should be able to open a blank Playground and the live preview will start up immediately. The "Hello, Playground!" code is present, but no live preview. Instead, I am just getting a blank preview screen, and I haven't been able to figure out how to get it to show up. Any ideas?

Thank you!

I assume that your playground code is something like this

import UIKit

var greeting = "Hello, playground"

In which case press the arrow in the circle icon.

At the bottom of the panel you should see two icons - a square with a thick line in it, and a blank square. Press the icon with the thick line in it, and a new area should open up beneath it.

Replace the existing code with

import SwiftUI

var greeting = "Hello, playground"
print (greeting)

And press the arrow in a circle (Run) icon again.

Where this takes you, and what you do next will be up to you.

Happy coding.

Thank you, that worked! I don't need to use the print command anymore, and the live preview is showing on the right hand side.

Hi! 12 months later and I'm in exactly the same boat as @zeldazeldajones. Except, I can see the Debug Area at the bottom and the Live Preview area on the right, it's just that they are blank. Sure, they update when I run the playground, but in the interests of trying to learn (and a degree of pedantry) I would really like to be able to see the live output as seen in Paul's videos.

I'd greatly appreciate any assistance anyone can please provide, thanks!
