Good Things: SwiftUI on Mojave in iOS Playgrounds

Yes, you can upgrade to the Catalina Beta. Or, you can keep getting work done on Mojave and still enjoy the glory of SwiftUI exploration.

  1. Install Xcode 11 beta along side your 10.2.x Xcode
  2. Using the beta, create an iOS playground. (This won’t work with macOS, which attempts to use the native frameworks, which don’t  yet support SwiftUI)
  3. Import both SwiftUI and PlaygroundSupport.
  4. Set the live view to a UIHostingController instance whose rootView conforms to View.

Here’s an outline of the basic “Hello World” setup:

From there, you can create pages for each of your SwiftUI experiments, allowing you to build short, targeted applets to expand your exploration and understanding of the new technology.

Parse to shut down on 28 Jan 2017

Kevin Lacker writes on the Parse blog,

We have a difficult announcement to make. Beginning today we’re winding down the Parse service, and Parse will be fully retired after a year-long period ending on January 28, 2017. We’re proud that we’ve been able to help so many of you build great mobile apps, but we need to focus our resources elsewhere.

We understand that this won’t be an easy transition, and we’re working hard to make this process as easy as possible. We are committed to maintaining the backend service during the sunset period, and are providing several tools to help migrate applications to other services.

Parse will release a database migration tool and will open source ParseServer. Regardless, this is going to come as a blow to a large segment of the iOS developer community.
