Overview of Swift

Swift is a new iOS, macOS, watchOS and tvOS programming language for developing an app. Many sections of Swift are acquainted with your C and Objective-C development experience. Swift's first publication was launched in 2010. It took nearly 14 years for Chris Lattner to come up with the first official version, and many other contributors endorsed it later. In Xcode 6 beta, Swift 4 was included. Things from other common languages such as Objective-C, Rust, Haskell, Ruby, PYTHON, C #, and CLU have been adopted by Swift developers. Swift blends the best  wisdom of the wider Apple engineering culture with modern language thinking. The compiler is performance-optimized and the language is developed without compromise. 

What is Xcode

Apple's primary application writing environment is Xcode, which involves an IOS or Mac OS running code editor, debugger, project manager, and toolchain. 

Swift Characteristics

• The programming characteristics are contemporary. 
• It provides the C and Objective-C syntax. 
• It's easy to read and comprehend its code. 
• It provides a great way for IOS and OS X applications to be coded. 
• It utilizes safer patterns of programming. 
• Swift has a playground function in which Swift programmers can write and execute their code to immediately see outcomes. 

Swift supplies its own version, including Int for integers, Double and Float for floating points, Bool for Boolean values and String for text information, for all basic C and Objective-C type. As outlined in Collection Types, Swift also offers strong versions of three major kinds of collections, Array, Set, and Dictionary. 

Like C, Swift utilizes the saving variables and refers to the values by the name. Swift also uses variable values that cannot be altered extensively. Constants in all of Swift are used to create code that is safer and clearer when working with values that need not be changed. In addition to familiar kinds, Swift presents sophisticated ones, such as tuples, which are not discovered in Objective C. Tuples allow you to set up groups of values and pass them around. Use a tuple to return several values as a single compound value from a function. 

Swift also presents optional kinds that deal with the lack of value. Either "there's a value," or "There's no value at all" are optional. The use of options is comparable to nil with Objective-C pointers, but they are not just working for classes but for any kind. Not only are optional characteristics safer and more expressive than none in Goal-C, but they are also central to many of the most strong characteristics of Swift. 

Swift is a type-safe language that allows you to understand the kinds of values with which your code works. If a String is required in part of your code, type safety protects you from mistaking an Int. Similarly, type safety protects you from passing an optional string to a non-optional string piece of code. Type safety enables you in the design phase to capture and solve mistakes as soon as possible.

Summary:

This module helped us in understanding basic characteristic of swift language . We have also got understanding of evolution of language and comparison with other programming languages. We have found multiple similarities in swift syntax with other programming language syntax.
