May 24, 2017 - Apple says 'App Development with Swift' teaches students a solid. New iOS Coding and Design School centred on App Store development.

Programming languages don’t die easily, but development shops that cling to fading paradigms do. If you’re developing apps for mobile devices and you haven’t investigated Swift, take note: Swift will not only supplant Objective-C when it comes to developing apps for the Mac, iPhone, iPad, Apple Watch, and devices to come, but it will also replace C for embedded programming on Apple platforms. Thanks to several key features, Swift has the potential to become the de-facto programming language for creating immersive, responsive, consumer-facing applications for years to come.

[ Get started:. . Keep up with the hottest topics in programming with InfoWorld’s. ] Apple appears to have big goals for Swift. It has optimized the compiler for performance and the language for development, and it alludes to Swift being “designed to scale from ‘hello, world’ to an entire operating system” in. While Apple hasn’t stated all its goals for the language yet, the launches of Xcode 6, Playgrounds, and Swift together signal Apple’s intent to make app development easier and more approachable than with any other development tool chain. Here are 10 reasons to get ahead of the game by starting to work with Swift now.

Swift is easier to read Objective-C suffers all the warts you’d expect from a language built on C. To differentiate keywords and types from C types, Objective-C introduced new keywords using the @ symbol. Because Swift isn’t built on C, it can unify all the keywords and remove the numerous @ symbols in front of every Objective-C type or object-related keyword.

Swift drops legacy conventions. Thus, you no longer need semicolons to end lines or parenthesis to surround conditional expressions inside if/else statements. Another large change is that method calls do not nest inside each other resulting in bracket hell—bye-bye, [[[ ]]]. Method and function calls in Swift use the industry-standard comma-separated list of parameters within parentheses. The result is a cleaner, more expressive language with a simplified syntax and grammar. Swift code more closely resembles natural English, in addition to other modern popular programming languages. This readability makes it easier for existing programmers from JavaScript, Java, Python, C#, and C++ to adopt Swift into their tool chain—unlike the ugly duckling that was Objective-C.

Swift is easier to maintain Legacy is what holds Objective-C back—the language cannot evolve without C evolving. C requires programmers to maintain two code files in order to improve the build time and efficiency of the executable app creation, a requirement that carries over to Objective-C. Swift drops the two-file requirement. Xcode and the LLVM compiler can figure out dependencies and perform incremental builds automatically in Swift 1.2. As a result, the repetitive task of separating the table of contents (header file) from the body (implementation file) is a thing of the past. Swift combines the Objective-C header (.h) and implementation files (.m) into a single code file (.swift).

Objective-C’s two-file system imposes additional work on programmers—and it’s work that distracts programmers from the bigger picture. In Objective-C you have to manually synchronize method names and comments between files, hopefully using a standard convention, but this isn’t guaranteed unless the team has rules and code reviews in place.

Xcode and the LLVM compiler can do work behind the scenes to reduce the workload on the programmer. With Swift, programmers do less bookkeeping and can spend more time creating app logic.

Swift cuts out boilerplate work and improves the quality of code, comments, and features that are supported. Swift is safer One interesting aspect of Objective-C is the way in which pointers—particularly nil (null) pointers—are handled. In Objective-C, nothing happens if you try to call a method with a pointer variable that is nil (uninitialized). The expression or line of code becomes a no-operation (no-op), and while it might seem beneficial that it doesn’t crash, it has been a huge source of bugs.

A no-op leads to unpredictable behavior, which is the enemy of programmers trying to find and fix a random crash or stop erratic behavior. Optional types make the possibility of a nil optional value very clear in Swift code, which means it can generate a compiler error as you write bad code. This creates a short feedback loop and allows programmers to code with intention. Problems can be fixed as code is written, which greatly reduces the amount of time and money that you will spend on fixing bugs related to pointer logic from Objective-C.
