Also, join us for #CompleteTheCode and Compiler Error, two segments that test both your knowledge and our knowledge on Swift, Apple, and all things development! Your hosts for this week: * Spencer Curtis (https://twitter.com/SpencerCCurtis) * Ben Gohlke (https://twitter.com/FerrousGuy) * Fernando Olivares (https://twitter.com/FromJRtoSR) * Dimitri Bouniol (https://twitter.com/DimitriBouniol) Be sure to also sign up to our monthly newsletter (https://codecompletion.io/), where we will recap the topics we discussed, reveal the answers to #CompleteTheCode, and share even more things we learned in between episodes. You are what makes this show possible, so please be sure to share this with your friends and family who are also interested in any part of the app development process.

Complete the Code How would you transform the code below to use the new async/await pattern? ```swift // 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 (https://twitter.com/intent/tweet?text=%23CompleteTheCode%20cc%2F%20%40CodeCompletion&original_referer=https%3A%2F%2Fcodecompletion.io) with hashtag #CompleteTheCode (https://twitter.com/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.
