And Swift 5 now introduces binary compatibility for apps. That means you no longer need to include Swift libraries in apps that target current and future OS releases, because the Swift libraries will be included in every OS release going forward. Your apps will leverage the latest version of the library in the OS, and your code will continue to run without recompiling. This not only makes developing your app simpler, it also reduces the size of your app and its launch time.
Swift is developed in the open at Swift. This broad community of developers, both inside Apple as well as hundreds of outside contributors, work together to make Swift even more amazing.
Swift already supports all Apple platforms and Linux, with community members actively working to port to even more platforms. Swift is perfect for use in server apps that need runtime safety, compiled performance and a small memory footprint. To steer the direction of Swift for developing and deploying server applications, the community formed the Swift Server work group. The first product of this effort was SwiftNIO, a cross-platform asynchronous event-driven network application framework for high performance protocol servers and clients.
It serves as the foundation for building additional server-oriented tools and technologies, including logging, metrics and database drivers which are all in active development.
To learn more about the open source Swift community and the Swift Server work group, visit Swift. Much like Swift Playgrounds for iPad, playgrounds in Xcode make writing Swift code incredibly simple and fun.
Type a line of code and the result appears immediately. You can then Quick Look the result from the side of your code, or pin that result directly below. The result view can display graphics, lists of results, or graphs of a value over time. You can open the Timeline Assistant to watch a complex view evolve and animate, great for experimenting with new UI code, or to play an animated SpriteKit scene as you code it.
Use Swift syntax to evaluate and interact with your running app, or write new code to see how it works in a script-like environment. Swift Package Manager is a single cross-platform tool for building, running, testing and packaging your Swift libraries and executables. Swift packages are the best way to distribute libraries and source code to the Swift community.
Configuration of packages is written in Swift itself, making it easy to configure targets, declare products and manage package dependencies. New to Swift 5, the swift run command now includes the ability to import libraries in a REPL without needing to build an executable. Swift Package Manager itself is actually built with Swift and included in the Swift open source project as a package. You can create an entirely new application with Swift today, or begin using Swift code to implement new features and functionality in your app.
Anyways, Apple you should update this book to provide a way for us to detect errors and notify you of them quickly. Something like that. Let's get one thing straight This resource is invaluable. And wonderfully, I repeat, wonderfully put together. I am a senior in college with experience in programming and this textbook is clearer than most. And the fact that this is teaching us how to build apps makes it even more difficult to build a textbook, because creating apps are difficult so the authors need to do a lot of "hand-holding" and almost teach us like if we had training wheels.
This is a whole new language and it takes a lot to teach it, especially to many people here who clearly seem like they need the hand-holding. Not a bad thing, just an obvious observation. The people who continue to complain are obviously just nit-picking and over-reacting and merely being distracted from the obvious use of this resource which is just to bring ios app building to the world and the common person-who does not know how to code.
Stop complaining! My God. Take the book and run with it because it is a wealth of knowledge. Read to learn code, don't read to find what is aesthetically pleasing to your eye and what kind of font they use, etc. Seriously, they are giving information free on building mobile software, take it and be happy.
For those of you complaining that this doesn't work on your iPhone? Universities and academic institutions around the world teach with Swift and Xcode on Mac, empowering their students with the best tools to build amazing apps. And to help Swift grow into an even more powerful language, we created a community where users can contribute directly to the Swift source code.
Join the community at Swift. Learn how Swift makes programming easier, more flexible, and more fun. Xcode is the Mac app used to build every other Mac app and every iOS app, too. It has all the tools you need to create an amazing app experience.
Get detailed technical information and an advanced overview of Swift. Check out the developer blog and stay up to date on the latest news. And enjoy free access to great resources like guides, videos, and sample code.
A new approach to coding that gives everyone the power to learn, write, and teach code. Developers are doing great things with Swift.
