iOS Development with Swift 2 Tutorial

A rapid introduction to the fundamentals of iOS development in Objective-C. The most obvious way to write code should also behave in a safe manner. Undefined behaviour is the enemy of safety, and developer mistakes should be caught before software is in production. Opting for safety sometimes means Swift will feel strict, but we believe that clarity saves time in the long run. Swift is becoming a more mature language with every update, but there are still things to fix.

So you look it up and use it again, then promptly forget it. So you look it up a third time and use it, and this time you only mostly forget it – some parts stick in your brain. This repeats again and again, each time with you having to refer to a tutorial or some other reference guide, until eventually the really core things have stuck in your head to the point where you can do it without referring elsewhere. As before, I want to explain each of those in more detail so you can understand why I think they are important – and why I consider them extension skills rather than core skills.

All about Concurrency in Swift – Part 1: The Present

Paul Hudson is the creator of Hacking with Swift, the most comprehensive series of Swift books in the world. He’s also the editor of Swift Developer News, the maintainer of the Swift Knowledge Base, and a speaker at Swift events around the world. Articles covering how to find jobs, how to do your best at interviews, and more. If you work super hard and get a job after 50 days, that’s fantastic – well done! If it takes you 500 days, that’s also fantastic and you should be just as proud. Heck, if it takes you five years I know it’s probably not what you wanted, but the end result is the same and that’s what matters.

  • So you look it up and use it again, then promptly forget it.
  • When you’ve perfected your code in the playground, simply move that code into your project.
  • Data validation in apps is important to make sure we save data conforming to the business rules.
  • In this course you will learn how to implement the MVVM design pattern and create the app from scratch in Xcode.
  • Undefined behaviour is the enemy of safety, and developer mistakes should be caught before software is in production.
  • “In some of our projects, we used the MulticastDelegate that allowed us to create one-to-many delegate relationships, i.e., to inform multiple objects whenever a change has happened to another object.
  • These are skills that will take you from your good place up to being in a fantastic place – you become even more employable, and the range of apps you’re able to build will grow even further.

I’m pretty sure most of the developers have their own libraries with the best stuff. These tips will help you save time and resources so you can spend more time focusing on the parts of code that really matter. Learn about Apple’s advanced mobile device hardware, characteristics of modern apps, the iOS software development kit, Apple developer programs, and Apple’s approach to security and distribution. In this course you will learn how to implement the MVVM design pattern and create the app from scratch in Xcode. This comprehensive course combines Swift Programming — a rapid introduction that will get you up to speed on Swift quickly — and SwiftUI Development, a thorough introduction to developing apps for the iOS platform.

iOS Container Views

Swift was first introduced by Apple in June 2014 and has gone through several updates. Fast forward to today, the company already released version 5.7 of the programming language along with Xcode 14 with more features. With over 8 years of development since its first release, Swift is no longer a brand new programming language.

Those are huge steps toward making Swift a more mature language. Do you know how the US differs from the rest of the world in terms of mobile swift vs objective-c preferences? According to Statcounter, the global market share of Android is about 72.7 percent, while that of iOS is 26.4 percent .

SwiftUI Fundamentals

There are no other special qualifications you need – get those core skills down, and you’re in a good place. SwiftUI was built for Swift, using language features to help you avoid problems and get maximum performance. In comparison, UIKit was written for Apple’s older language, Objective-C, and as a result has all sorts of quirks and cruft that came about as a result of its age. This is the core programming language from Apple – it has no concept of showing information on an iPhone’s screen, or downloading data from the internet, it’s just a language like JavaScript or Python. You use it to create variables, write functions, and so on; it’s just pure code. This book is written for beginners without any prior programming experience and those who want to learn Swift programming.

The apple provides various Accessibility features to be used for people with vision and hearing disabilities. The features like voiceover provide a voice reading information that appears on the screen. It allows the user to communicate with the OS with gestures. Apple keeps updating accessibility to provide new features like pronunciation editor, which can be used with the voice over, with iOS 10 in 2016. Unidirectional flow means that all the data in the application follows the same pattern, making the logic of your app more predictable and easier to understand. The unidirectional flow pattern works great in conjunction with the idea of a single source of truth.

Functional Reactive Awesomeness With Swift

Second, you should take into account what kind of background you had before you came to Swift. The fifth big problem folks hit when trying to learn is relying on Apple’s documentation. In this learning path, you’ll build two fully-functional iOS apps, and go into depth with the Swift Programming Language to learn how to create the logic behind your app. One billion iPhone users are waiting for the next amazing app. Apple’s Swift language makes iOS development easier than ever, offering modern language features, seamless integration with all iOS libraries, and the top-notch Xcode development environment. A clean and expressive language with a simplified syntax and grammar, Swift is easier to read and write.

If you’re a complete beginner to iOS and SwiftUI development and wondering how to get started, this is the course for you. Apple iOS provides a user-friendly interface that uses multi-touch gestures like swipe, tap, pinch, etc., to facilitate the users interacting with the applications. The users can trigger any event using switches, buttons and sliders. It uses internal accelerometers to respond to shaking the device or rotating in 3D.

What you will learn

Use Interface Builder to add buttons, switches, and sliders to a scene. Create actions and outlets, write some basic code, and learn how these tools work together. Learn how to create and store text using the string type. You’ll learn a variety of string methods that allow you to compare two strings, access specific characters within a string, and insert and remove values. You should be comfortable with the basic concepts of computer programming, including variables, strings, logic, and classes.
