Xcode Previews have been added in Xcode 11 and allow you to quickly preview the current state of your view. Although you might think that you need to use SwiftUI to make use of this great new feature, it's not true! Whether you're working with a custom UIView or with a custom UIViewController, they both support previews in the new canvas. This is great, as this new feature allows you to iterate fast and implement designs even faster.

Note that using the latest Xcode does not prevent your application from targeting older iOS versions. The iOS versions you support is based upon your Info.plist entry and the APIs your application uses. It is possible to install multiple versions of Xcode side-by-side, with different names such as Xcode101.app and Xcode102.app. For example, building against the iOS 12 SDK in Xcode 10.x opts your app in to support the iPhone XS Max and iPhone XR screen sizes. Build with Xcode 9.x (against the iOS 11 SDK) and even when opened on an iPhone XS Max running iOS 12, your app will use the iPhone X resolution and be scaled to fill the larger screen.

Xcode Version History

1. Every iOS, iPadOS, macOS (OS X), tvOS and watchOS developer and non-developer (general public users) are very well aware of Apple Xcode developer toolset, which includes all the required tools, utilities and frameworks to create, develop and build games and applications software for iOS, iPadOS, watchOS, tvOS and macOS (OS X) desktop and mobile operating systems that run on iPhone, iPad, iPod.
2. IOS 13.6.1 should be very well supported by Xcode 11.7. Try connecting the iPhone 7 Plus via cable to your Mac and try if you can see it as a run destination in Xcode 11.7.

The SwiftLee view controller we're about to preview

In the following example, we have a very simple SwiftLeeViewController which shows the SwiftLee logo in a UIImageView. The view controller is set up right from the interface builder:

And the code for the view controller is empty:

Using Xcode Preview while supporting older iOS versions

WWDC is great, but a big downside is that you're probably not going to use many new features until you drop iOS 12. Xcode Previews, however, does not have to be such feature!

The trick is to set the OS deployment target to iOS 13 while developing. This allows the canvas to generate previews, just like it does with SwiftUI.

But how do I use these protocols which are only available from iOS 13 and up?

We can make use of the canImport for this, together with the availability APIs.

To add support for our SwiftLeeViewController we have to add the following code:

Let's break this down.

We start with the canImport which makes sure that our project still builds for developers without the latest Xcode version. They might not be able to import the SwiftUI framework yet.

Do note that we only import the SwiftUI framework for our debug configuration, so we will never import this framework in shipped code.

The SwiftLeeViewRepresentable is our wrapper and converts our UIView to a SwiftUI View. Inside the makeUIView method we basically instantiate our view controller. This method can be used to instantiate any view, also a custom view or a view controller created from code.

We end with the SwiftLeeViewController_Preview implementing the PreviewProvider protocol. This will automatically enable the preview canvas in Xcode and will actually show the preview! We only have to return the SwiftLeeViewRepresentable Voice changer plus. instance to make this work. We use the @available code to make sure our code still builds if we ever change back the OS version for our debug configuration as well.

The only thing you need to do is switching your project settings to iOS 13.0 while developing. Once your UI is done, you can switch back to the minimum iOS version you're supporting. The best thing is to set this version fixed for your release builds. Computer not recognising usb memory stick. For example, when you support iOS 11 and up:

Although the workflow requires you to switch the OS version, it does allow you to use the Xcode previews. This can improve development speed and allows you to start working with Xcode Previews before you drop iOS 12 support.
