On the latest episode of the AppStories podcast, MacStories editor-in-chief Federico Viticci sat down with Apple's software engineering chief Craig Federighi to discuss WWDC 2019 announcements, including Project Catalyst, SwiftUI, and iPadOS. Craig Federighi at WWDC 2019 Project Catalyst will make it much easier for developers to extend iPad apps to the Mac. In many cases, adding macOS support to an iPad app is as easy as opening an Xcode project and clicking the Mac checkbox, although Apple encourages developers to further optimize their apps to offer a true Mac experience. Federighi believes Project Catalyst will allow many developers to bring their iPad apps to the Mac, as Apple has bridged the gap between its UIKit framework for iOS apps and its AppKit framework for Mac apps: Project Catalyst Federighi expressed excitement about Project Catalyst, noting that he has seen many apps that look fantastic on the iPad that he has wanted on the Mac. With macOS Catalina and Xcode 11, that is now a possibility, with Twitter being one of several companies that plans to extend their iPad app to the Mac. He added that Project Catalyst gives Apple the "same kind of benefits of being able to have a single team that can focus on making one thing the best and release it across all of our platforms," which makes "a ton of sense" to the company. SwiftUI As for Apple's new SwiftUI framework, which enables developers to use easy-to-understand declarative code to create full-featured user interfaces, Federighi said giving developers a tool that is "that expressive and that interactive" is going to result in better ideas and thereby better apps moving forward: Turning to the new iPadOS platform, Federighi said that the iPad has "become something really distinct from the phone" over the years and, accordingly, was deserving of an operating system that provides a "distinct experience": iPads now fully support external drives Humorously, Federighi also poked fun at the iPad's newly added support for external storage such as USB drives and SD cards: The full interview can be listened to on the AppStories podcast over at MacStories.
