Xcode On Catalina

Apple iOS Developers can now access Xcode 12.2 on MacinCloud Big Sur and Catalina servers. Xcode is an integrated development environment (IDE) that allows users to create and test iPhone, iPad, Mac and Apple Watch apps using OSX and iOS. Xcode supports a variety of programming languages such as Swift language, C, C, AppleScript, and etc. The new image contains Xcode 11.2, running on Catalina. You can select this image by selecting 11.2.0 as follows: jobs: build: macos: xcode: 11.2.0 This is the first image that we’ve built with Catalina, so there might be some bugs – please let us know if you find anything out of the ordinary. With the Catalina upgrade, my Xcode did not automatically update to 11.1. The App Store kept trying to update Xcode each night through automatic updates. On its own, it never succeeded. Once it reported it could not download Xcode: Unable to Download App. 'Xcode' could not be installed. Please try again later.

Xcode 12 release includes Swift 5.3 and SDKs for iOS 14, iPadOS 14, tvOS 14, watchOS 7, and macOS 11. The Xcode 12 beta release supports on-device debugging for iOS 9 and later, tvOS 9 and later, and watchOS 2 and later. Xcode 12 beta requires a Mac running macOS Catalina 10.15.4 or later.iOS nine and later, tvOS 9 and later, and watchOS 2. I have a Mac running Catalina. It is almost new and I did not migrate anything from the old Mac, so should be a very clean install. I installed Xcode 11 from the App Store. Yesterday it wanted to update to Xcode 11.1. But the update took a long time and then failed. Try again later.

Start with sharing how much available storage remains on your boot drive. Click Macintosh HD on your Desktop, and then press option+command+i to open a Get Info panel. What does Available show for the amount?

Xcode may be an 8GB download, but its installation requires double-digit final storage, plus any temporary storage that it takes during the installation process. I would not attempt it with less than 20 GB of available storage. Ideally more.

I just removed Xcode 11.3.1 from a Mojave 10.14.6 system and it freed up 27GB of storage after emptying the Trash.

Apple has announced Xcode version 12 at #WWDC20; they released the beta version on the same day. Xcode is in the middle of all development on Apple's platforms, and with Xcode 12, it's a fresh update to match macOS Big Sur.

With Xcode-12, it is faster to open multiple files. Navigator fonts now match the system size or are often set to small, medium, or large. And Xcode 12 builds macOS Universal apps by default to support new Macs with Apple silicon.

What's New in Xcode 12?

SwiftUI

SwiftUI (no SwiftUI 2.0) offers some new features with many performance improvements. Missing localized strings here office for mac 2016. 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. Mixmeister update catalina.

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.

Flinto. 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.

Xcode On Macos Catalina

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 9 On Catalina

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.

Xcode 12.2 On Catalina

Conclusion

Install Xcode On Catalina

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.
