![]() To view the Scroll Hitch bar graph, click on the Scrolling section in the Metrics Organizer window. You can use these metrics to identify animation delays users encounter while scrolling in your application. Organizer now displays scroll-hitch metrics.Organizer now allow to compare and contrast metrics associated with different version of an application.Choose any app from any of your developer teams, then quickly navigate to inspect crash logs, energy reports, and performance metrics, such as battery consumption and launch time of your apps when used by customers. Xcode 12 has a completely new Organizer with all-new design that groups all critical information about each of your apps together in one place. With Xcode 12, SwiftUI views can now be shared with other developers, and appear as first-class controls in the Xcode library.So, you can build widgets using SwiftUI that'll works all Apple platforms. So, now you can share life cycle code across all Apple platforms. Now SwiftUI has complete new life cycle management API for apps built with SwiftUI.Also, existing SwiftUI code continues to work, with faster performance, better diagnostics, and access to new controls. SwiftUI (no SwiftUI 2.0) offers some new features with lots of performance improvement. Xcode 12 for macOS Universal Apps beta requires a Mac running macOS 11 or later.

Xcode 12 supports on-device debugging for iOS 9 and later, tvOS 9 and later, and watchOS 2 and later. Xcode 12 supports developing apps for iOS 14, iPadOS 14, tvOS 14, watchOS 7, macOS 10.16. Xcode 12 also builds Universal apps by default to support upcoming Mac with Apple Silicon. Xcode 12 includes everything you need to create amazing apps for all Apple platforms. Some features may require Internet access.Xcode is the complete developer toolset used to create apps for Apple TV, Apple Watch, iPad, iPhone, and Mac. To submit your apps to the App Store you must be a member of the Apple Developer Program. To test or run applications on an iPhone, iPad, Apple TV, or Apple Watch all you need is a free Apple ID. Create custom instruments with unique visualizations to analyze your own code and frameworks.Analyze your app directly, or sample the entire system with very little overhead.Identify performance bottlenecks, then dive deep into the code to uncover the cause.Compare CPU, disk, memory, and GPU performance as graphical tracks over time.Data tips and Quick Look can inspect a variable by hovering your mouse over code while debugging.Open Quickly instantly opens any file within your project.Refactoring makes it easy to modify the structure of Swift, Objective-C, C, and C++ code.Professional editor and debugger keep your code front and center Animations are built using simple commands that describe the action you want to see.SwiftUI code is always in perfect sync with the graphical design canvas and previews.Preview SwiftUI code or UIKit interfaces in different screen sizes, orientations, and font sizes.Design canvas graphically builds UI views using the library of controls and modifyers.SwiftUI uses declarative Swift code that clearly describes your interface.SwiftUI and Interface Builder make it easy to design your interface Source control navigator and service integrations help you manage code across a team.Live issues display errors as you type, and Fix-its improve your code with just a click.Split editors in virtually unlimited ways, show previews, or choose an assistant to see related content.View debugging shows a 3D stack of all your app's UI view layers at runtime.Playgrounds are a fun way to experiment and interact with Swift code. ![]() SwiftUI is a revolutionary framework to create user interfaces with a declarative Swift syntax.Swift is an intuitive programming language that is safe, fast, and modern.Innovative tools help you create great apps Xcode includes the Xcode IDE, Swift and C/C++/Objective-C compilers, Instruments analysis tool, simulators, the latest SDKs, and hundreds of powerful features: The Xcode IDE combined with the Swift programming language make developing apps easy and fun. Xcode provides developers a unified workflow for user interface design, coding, testing, and debugging. Xcode includes everything developers need to create great applications for Mac, iPhone, iPad, Apple TV, and Apple Watch.
