URLSession.shared.data(from: url) fails in Swift Playgrounds for Mac

Forums > SwiftUI

I followed this post on receiving and sending data with UrlSession in Swift Playgrounds for iPad, and everything worked great.

I opened the same code in Swift Playgrounds for Mac, and the line:

let (data, _) = try await URLSession.shared.data(from: url)

silently fails everytime. I exported a small snippet to a playground in Mac, and found that adding:

import PlaygroundSupport
PlaygroundPage.current.needsIndefiniteExecution = true

At the beggining of the script fixes this in the playground. I am wondering if there is a way to move this code to the app version and get this up and running on the Mac? Or maybe this code was never designed to run on a Macbook?

   

The first line certainly should work in Xcode without the two playground lines.
