Complete the Code

How would you transform the code below to use the new async/await pattern?

// How would you transform the code below to use the new async/await pattern?

print("Preparing request…")

urlSession.dataTask(with: httpRequest) { data, response, error in
    DispatchQueue.main.async {
        print("Received response: \(response)")
    }
}.resume()

print("Sent request!")

Be sure to tweet us with hashtag #CompleteTheCode if you know the answer!

Compiler Error

This week's Compiler Error has a theme: SwiftUI View Modifiers!
1 - Much like UIKit, SwiftUI allows the interface orientation to be manipulated using statusBar(orientation:), moving the status bar to one of the four screen edges.
2 - Tooltips can be added to SwiftUI views using the help(_:) modifier, helping to guide the user around the interface without them needing to directly invoke any actions.
3 - Any view in the hierarchy can be modified with onOpenURL(perform:) to perform localized URL handling so long as it is part of the hierarchy when the URL is opened.
4 - A badge can be added to tab bar items using the badge(_:) modifier, but this will also add a visual indicator to list rows to help convey supplementary information.
