What's New in Xcode 12?

SwiftUI

Install Xcode 9 On Catalina

SwiftUI (no SwiftUI 2.0) offers some new features with many performance improvements. The existing SwiftUI code continues to figure, with faster performance, better diagnostics, and access to further controls.

SwiftUI has a complete new lifecycle management API for apps built with SwiftUI. So, now you'll share life cycle code across all Apple platforms.

With Xcode 12, SwiftUI views can now be shared with other developers, and appear as first-class controls within the Xcode library.

Organizer

Xcode 12 features an entirely new Organizer with an all-new design that groups all critical information about each of your apps together. Choose any app from any of your developer teams, then quickly navigate to examine crash logs, energy reports, and performance metrics, like battery consumption and launch time of your apps when employed by customers.

The organizer now displays scroll-hitch metrics. You'll use these metrics to spot animation delays users encounter while scrolling in your application. To look at the Scroll Hitch bar chart, click on the Scrolling section within the Metrics Organizer window.

The organizer now also provides Disk Writes diagnostic reports. You'll use these reports to optimize the disk-write performance of your apps.

Interface Builder

Xcode 12 features a new tab model. With this updated model, you'll re-arrange the document tabs to make a working set of files for your current task, and configure how content is shown within each tab.

Xcode 12 comes with a replacement code completion UI with only the knowledge you would like. So, it's more compact and takes up less screen space.

The project navigator now takes advantage of the system setting to resize 'Sidebar Font & Icon Size,' almost like Finder. You can also choose a single font and icon size for Xcode within Xcode Preferences.

Xcode 12 adds a replacement minimap for the Interface Builder canvas. You can drag, double-click or command-click within the minimap to specialize in a selected area. You can enable and disable this minimap with Editor > Canvas > Minimap. This may be very helpful in large size storyboards.

Debugging

Xcode 12 now displays the breakpoint hit count for a specific breakpoint location. Like 'Thread 1: breakpoint 1.1 (14), ' 14 means breakpoint 1.1 has been hit 14 times.

You can re-order breakpoint actions by dragging and dropping them into a unique position. You can name a breakpoint, and reference it by name from another breakpoint's work. For instance, to enable a previously disabled breakpoint called 'MyBreakpoint,' type break enables MyBreakpoint in an action's Debugger Command field.

The breakpoint contextual menu now has a choice to delete all the disabled breakpoints.

Simulator

To keep Simulator ahead of other applications, you'll select Window > to stay Top. Now Simulator, by default, uses the internal microphone unless you manually select a particular audio source.

Simulator now supports 32-bit & 64-bit processes for watchOS 7. To verify watchOS projects are 64-bit clean in Simulator, confirm ARCHES is about to its default value.

With Xcode 12, Simulator supports simulating Nearby Interaction for devices that support the feature. Dragging the device window around on the screen will update the simulated distance between the two devices.

Playgrounds

Playgrounds now support asset catalogs.

Xcode 12 Report Navigator now includes Playground build logs alongside Project build logs. If a Playground live view features a size of zero, a banner now indicates why the live view isn't visible.

Xcode Playground now automatically compiles Core ML models in its Resources folder, and Playground code can access the generated ML model interface.

Xcode Playgrounds can now import and use Swift packages and frameworks. Select the Build Active Scheme checkbox within the Playground's File inspector and make sure that the active scheme builds the package or framework target.

Store Kit (Local Test Environment)

Xcode 12 now supports the testing of In-App Purchases (IAP) directly in Simulator or on a connected device, employing a new local StoreKit test environment.

It is now possible to customize Default Execution Time Allowance and Maximum Execution Time Allowance within the Test Plan Editor. But during this version of Xcode, these settings are disabled.

UI Testing now can handle banner notifications on iOS that block the navigation bar during UI testing.

Swift Packages

You can now declare conditionals Swift packages target dependencies, like limiting the dependencies by a platform.

Swift packages can now contain resources like asset catalogs, images, localized content (.lproj), storyboards, and other files. A dependent package adds the package's code and support to the app bundle to be used at runtime.

Universal Apps

Xcode 12 for macOS Universal Apps includes a standard macOS SDK that contains all the frameworks, debuggers, compilers, and everyone other tools you would like to create apps to support Apple Silicon and Intel x86_64 CPU. Even Xcode 12 is made as a Universal app.

When you open your existing project in Xcode 12, your app will automatically get updated to get release builds & archives as Universal apps.

Conclusion

Xcode 12 run destination menu added an 'Any Mac' destination for Mac schemes. This new build destination will build each target within the system for all supported architectures, no matter the native structure of the local Mac.

Xcode is a complete developer toolset for creating apps for Mac, iPhone, iPad, Apple Watch, and Apple TV. Xcode brings user interface design, coding, testing, debugging, and submitting to the App Store into a unified workflow.

Downloading and updating Xcode

The current release of Xcode is available as a free download from the Mac App Store. The Mac App Store will notify you when an update is available or you can have macOS update automatically as it becomes available.

Submitting apps to the App Store using Xcode

Xcode provides an integrated workflow for Apple Developer Program members to prepare and submit apps to the App Store. Use the latest version of Xcode available on the Mac App Store to submit your apps or, when available, the latest Release Candidate from the Downloads page.

Xcode 9 Catalina Free

Don't submit apps built using beta software, as beta versions of Xcode, Operating Systems, and SDKs are for development and testing only.

Providing feedback and reporting bugs

Your feedback goes a long way toward making Xcode even better. With Feedback Assistant, you can report issues or request enhancements to APIs and tools. Provide detailed information about issues, including your system and developer tool versions, and any relevant crash logs or console messages. To ask questions and find answers from Apple engineers and other developers, visit the Apple Developer Forums.

Invalid private key and certificate pairing

If you receive an error message saying, 'Xcode could not find a valid private-key/certificate pair for this profile in your keychain,” the Keychain Access application on your Mac is missing either the public or private key for the certificate you’re using to sign your app.

This often happens when you're trying to sign and build your app from a different Mac than the one you originally used to request your code signing certificate. It can also happen if your certificate has expired or has been revoked. Ensure that your app’s provisioning profile contains a valid code signing certificate, and that the Keychain Access application on your Mac contains that certificate, the private key originally used to generate that certificate, and the WWDR Intermediate Certificate.

For instructions on how to resolve this and other code signing errors, review the Code Signing Support page.
