Xcode Mac App Store
Xcode 12.1 includes Swift 5.3 and SDKs for iOS 14.1, iPadOS 14.1, tvOS 14, watchOS 7, and macOS Catalina Platform features. App Clips are a small part of your app that’s discoverable at the moment it’s needed, loads in seconds, and launches quickly.

App Clips are a small part of your app that’s discoverable at the moment it’s needed, loads in seconds, and launches quickly. This affects Xcode 12 when downloaded from the Mac App Store. We're aware of the problem and we're working on a fix. As a workaround in the meantime, documentation is available on developer.apple.com, or if necessary, Xcode 12 can be downloaded from the More Downloads area. After the next Xcode update, re-download Xcode from the Mac App Store.
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.
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.
Tools and resources
Use Xcode 12 and these resources to build apps for macOS Big Sur.
-->Overview
Xamarin.Mac apps can be distributed in two different ways:
- Developer ID – Applications signed with a Developer ID can be distributed outside of the App Store but are recognized by GateKeeper and allowed to install.
- Mac App Store – Apps must have an installer package, and both the app and the installer must be signed, for submission to the Mac App Store.
This document explains how to use Visual Studio for Mac and Xcode to setup a AppleDeveloper account and configure a Xamarin.Mac project for each deploymenttype.
Mac developer program
When you join the Mac Developer Program the developer will be offered a choice to join as an Individual or a Company, as shown in the screenshot below:
Choose the correct enrollment type for your situation.
Note
The choices made here will affect the way some screens appear when configuring a developer account. The descriptions and screenshots in this document are done from the perspective of an Individual developer account. In a Company, some options will only be available to Team Admin users.
