Semicolons are not required at the end of statements - except when used to separate multiple statements typed on the same line in a source file.However, Swift has some improvements and differences from C-inspired languages that you may have to become accustomed to, such as: Swift has both struct and class semantics, as do C++ and C#. Swift has the concept of named variables, which are mutable, and named constants, which are immutable.Swift data type names and usage are similar to that in Java, C#, and C++.Single and multiline comments follow the same syntax as in C++ and Java.Functions accept one or more parameters, and return values.Units of work in Swift are modularized using functions and organized into types.More than one statement is allowed per editor line when separated by a semicolon ( ).Programs are made up of statements, executed sequentially.If you have previous programming experience in other C-inspired languages, many aspects of Swift will seem familiar, for example: Like many modern programming languages, Swift draws its most basic syntax from the programming language C. In this first section, we’ll look at the basic language syntax for Swift. You can check it out for free here! Swift Syntax It also has numerous activities for you to complete. Let’s get started! This crash course is adapted from Next Tech’s full Beginning Swift course, which includes an in-browser sandboxed environment with Swift pre-installed. Variable and constant naming conventions.In this quick crash course, we will cover the fundamentals of using the Swift programming language. While not based on an older language, Swift, in the words of its chief architect, Chris Lattner, “ was inspired by drawing ideas from Ruby, Python, C#, CLU, and far too many others to list”. Unlike many object-oriented languages, which are based on older procedural languages - for example, C++ and Objective-C are based on C - Swift was designed from the ground up as a new, modern, object-oriented language that makes programming faster and easier, and helps developers produce expressive code that’s less prone to errors than many languages. While it remains primarily used by developers targeting the Apple macOS and iOS platforms, Swift is also fully supported on Linux, and there are unofficial ports under development for Windows as well. It was made open source in December 2015. It was primarily intended as a replacement for the aging Objective-C language that was the foundation of OS X and iOS software development at the time. Swift is a relatively new programming language designed by Apple Inc which was initially made available to Apple developers in 2014.
