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.
Learn Cocoa for the Mac, Second Edition, completely revised for OS X Mountain Lion and XCode 4, answers these questions and more, helping you find your way through the jungle of classes, tools, and new concepts so that you can get started on the next great OS X app today.

Dec 09, 2017 As a Windows app programmer that wants to also develop native iOS and Android apps, one should learn to develop native macOS apps first! In my opinion it’s easier to learn standard Cocoa first, and only then Cocoa Touch (sharing, of course, the Foundation and other concepts). Mostly because on a Mac you have more power, a large screen, and – even more important – a mouse, just like it.
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 Complete MacOS Developer Course - Apps for the Desktop! 4.5 (811 ratings) Course Ratings are calculated from individual students’ ratings and a variety of other signals, like age of rating and reliability, to ensure that they reflect course quality fairly and accurately.
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.
Stocks was part of iOS 1 (iPhone OS 1). Voice Memos was part of iOS 3 (iPhone OS 3). News and Home, iOS 10. With Mojave, all of them are finally coming to the Mac. That they're finally coming is good. That it took so long is terrible.
I know I sound like the parent yelling about the messy room just as the kids start cleaning it up, but Mac customers are people too and addressing longstanding gaps in functionality is one thing — addressing the issues that cause longstanding gaps in functionality is another, far more important thing.
Apple needs to do both and, starting with Mojave, it is.
Back (and forward) to the Mac
News, Stocks, Voice Memos, and Home all kinda look like the iPad versions wrapped in Mac-specific interface elements and mouse and pointer support. And that's exactly what they are.
When Apple first began planning the App Store for iPhone, there was some internal debate over whether the company should use the existing Mac frameworks of AppKit or the increasingly popular web frameworks of WebKit.
Apple ultimate decided it needed to do something new and created UIKit.
For the last decade, AppKit has advanced considerably. /usb-3-card-for-el-capitan.html. But, thanks to the popularity of iPhone and the iOS App Store, UIKit has exploded.
Because of everything Apple's done over the years with AutoLayout, size classes, and app bundles, making iPad versions of iPhone apps has been relatively easy. tvOS versions, even.
Not so with the Mac. If a developer of a popular iOS app wanted to bring it to the Mac, large parts of it had to be ported from UIKit to AppKit. Even if the developer was Apple.
That's why many developers of popular iOS apps didn't bother. Even Apple.

In many cases, it wasn't because they didn't want to. They simply lacked the resources necessary to move the apps over given how much work they felt they still had to do to maintain their success on iOS. Yes, still including Apple.
The good thing about problems Apple has to solve for itself is that it typically solves them for developers as well. And they have, even if the solution has been obvious to some and terrifying to others for years:
UIKit on the Mac.
From Classic to Carbon to Cocoa to.. UIKit
Apple is positioning UIKit as another option for developers, alongside AppKit, WebKit, and the graphics engines often used by games and some design apps. (And, yeah, the horrible Electron — localized Chrome tab — apps that are the new Adobe Air or Java apps.)
It's part of a multi-year project that's being worked on by many teams within Apple, and should result in pushing not just Mac Apps but all Apple apps forward.
Because iOS and macOS share common foundations, sliding UIKit apps in alongside AppKit apps, it's not like starting from scratch. But, because iOS and macOS share very different user interface paradigms, a lot of work still has to be done.
Apple is going to make that easier by moving key UIKit frameworks to the Mac, and adapting them for trackpad/mouse and pointer control, Mac interface conversions like the window-controlling traffic lights, scroll bars and resizing, and the Mac versions of copy and paste and drag and drop.
That where News, Stocks, Voice Memos, and Home fit back into this. Apple is using them to dog-food the first phase of this project.
They're all iPad apps that have been brought to the Mac with 'very few code changes', according to Apple.
Evolve or die

I've been using the 'Marizpan' — or UIKit apps on Mac — for a while. They're way better and more resource efficient than Electron apps — hi, Slack! — and feel better than progressive web apps, which still feels like something being pushed on the market to serve program manager and not engineering or customer needs.
They don't feel like traditional Mac apps to me, though. At least not yet. They're so freshly ported their touch-centric interfaces still squeak of iPad every time they spin around too quickly.
Maybe that'll change over the course of the year. Or maybe what we consider to be traditional Mac feel will change, just as it did when we transitioned from Classic to Carbon to Cocoa. And there'll be just as much grumbling and hot-taking along the way, I'm sure.
The Mac has to keep evolving, though, and Mac apps along with it. It's been doing it for going on two decades already and it'll keep on doing it, hopefully for many more.
Again, it's going to take a couple of years to get through it but the Mac app ecosystem should end up all the more vibrant because of it.
Phase II starts in 2018 when Developers are going to get a chance to start working with it.
