macOS Big Sur takes the most advanced operating system in the world to a whole new level of power and beauty, making your apps look better than ever on an all-new interface. New widget features and the new widget gallery help you deliver more value to your users. Adding intelligence to your apps with machine learning is even simpler and more extensive with new tools, models, training capabilities, and APIs. You can create more powerful Mac versions of your iPad apps with Mac Catalyst. And you can now easily bring your extensions to Safari — and to the App Store.
All-new Interface
macOS Big Sur brings a new design that’s been finely tuned for the powerful features that make a Mac a Mac. Core features, such as the menu bar and Dock, take advantage of the large Mac display, with translucent backings and spacious pull-down menus. The new Control Center, designed just for Mac, provides quick access to controls while keeping the menu bar clutter-free. Notification Center puts recent notifications and powerful new widgets together in a single view for at-a-glance information as you work. And a streamlined new design for apps features full-height sidebars and integrated toolbar buttons.

This tutorial is a beginner's guide to Objective-C for iOS developers who already know object-oriented programming. It covers all the concepts you need to know in Objective-C for iOS and OS X programming. Cocoa learning tutorials. This tutorial teaches you how to create a Cocoa application from scratch without any programming or Xcode. Jun 15, 2020 According to Apple, “Swift is a robust and intuitive programming language created by Apple for building apps for iOS, Mac, Apple TV, and Apple Watch. It’s designed to give developers more freedom than ever. Swift is easy to use and open-source, so anyone with an idea can create something incredible.”. Because of Swift’s popularity and power, the world of academia has created courses.
Widgets
Easily build widgets using the WidgetKit framework and the new widget API for SwiftUI. Widgets now come in multiple sizes, and users can visit the new widget gallery to search, preview sizes, and add them to Notification Center to access important details at a glance.
Safari Extensions
With support for the popular WebExtension API, it’s even easier to bring powerful extensions to Safari. Xcode 12 even includes a porting tool to streamline the process.
The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community.
Machine Learning
With macOS Big Sur, creating apps that leverage the power of machine learning is even easier and more extensive with additional tools in Core ML for model deployment, new models and training capabilities in Create ML, more APIs for vision and natural language, and improved resources for training on Mac and converting models to Core ML format.
Mac Catalyst
Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen. Provide full control of your app using just the keyboard, take advantage of the updated Photos picker, access more iOS frameworks, and more.
User privacy on the App Store.
Later this year, the Mac App Store will help users understand apps’ privacy practices. You’ll need to enter your privacy practice details into App Store Connect for display on your product page.
Universal App Quick Start Program
Get your apps ready for Apple Silicon Macs. Create next-generation Universal apps that take full advantage of the capabilities the new architecture has to offer. Get all the tools, resources, support, and even access to prototype hardware you’ll need. You can also watch a collection of videos from WWDC20 to help you get started.
Tools and resources
Use Xcode 12 beta and these resources to build apps for macOS Big Sur.

Xamarin offers a path for developers targeting iOS to move their non-user interface code to platform agnostic C# so that it can be used anywhere C# is available, including Android via Xamarin.Android and the various flavors of Windows. However, just because you use C# with Xamarin doesn't mean you can't leverage existing skills and Objective-C code. In fact, knowing Objective-C makes you a better Xamarin.iOS developer because Xamarin exposes all the native iOS and OS X platform APIs you know and love, such as UIKit, Core Animation, Core Foundation and Core Graphics to name a few. At the same time, you get the power of the C# language, including features like LINQ and Generics, as well as rich .NET base class libraries to use in your native applications.
Additionally, Xamarin allows you to leverage existing Objective-C assets via a technology know as bindings. You simply create a static library in Objective-C and expose it to C# via a binding, as illustrated in the following diagram:
This doesn't need to be limited to non-UI code. Bindings can expose user interface code developed in Objective-C as well.
Transitioning from Objective-C
You'll find a plethora of information on our documentation site to help ease the transition to Xamarin, showing how to integrate C# code with what you already know. Some highlights to get you started include:
- C# Primer for Objective-C Developers - A short primer for Objective-C developers looking to move to Xamarin and the C# language.
- Walkthrough: Binding an Objective-C Library - A step-by-step walkthrough for reusing existing Objective-C code in a Xamarin.iOS application.
Binding Objective-C
Once you have a grasp of how C# compares to Objective-C and have worked through the binding walkthrough above, you'll be in good shape for transitioning to the Xamarin platform. As a follow up, more detailed information on Xamarin.iOS binding technologies, including a comprehensive binding reference is available in the Binding Objective-C section.
