Hi ! I am trying to run some async code before setting up the playground liveView, but I cannot figure out why it keeps crashing. I started up with a task I was waiting on the result before configuring the liveView, and now I am having all async work in a dedicated function, which seems to work fine : imageView has the correct width, and the line playground preview shows the image I am fetching online ! In both cases, I get the same result. Would that error be obvious to anyone ? import Foundation import UIKit import PlaygroundSupport let image = try await getImage() let imageView = UIImageView(image:image) var liveView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: 1050, height: 1050)) liveView.addSubview(imageView) print("before set liveView. imageView.width = \(imageView.frame.width)") PlaygroundPage.current.setLiveView(liveView) // crash here the getImage prototype being : public func getImage() async throws -> UIImage? And the console output : before set liveView. imageView.width = 960.0 Playground execution failed: error: execution stopped with unexpected state. error: Execution was interrupted, reason: shared-library-event. The process has been left at the point where it was interrupted, use "thread return -x" to return to the state before expression evaluation.
