Swift is a new programming language that improves on Objective-C. Functions in Swift are closures and instance variables are backed by stored properties instead of directly existing. Swift passes values by value rather than reference and classes cannot inherit but can interoperate with Objective-C code through a migration process that allows mixing Swift and Objective-C files in the same app.

MongoDB World 2018: A Swift Introduction to Swift
Swift is a new programming language released by Apple in 2014 that is designed to be safer, more modern, and work seamlessly with Objective-C. The document discusses building a MongoDB driver in Swift, highlighting some of Swift's key features like protocols, extensions, generics, and optionals that make it well-suited for this task. Interfacing Swift with existing C-based MongoDB drivers also presents challenges around representing BSON data types and pointer types that the driver had to address. Future work on the driver includes implementing more of the MongoDB API and taking advantage of newer Swift features.
Swift programming language
Swift is a new programming language developed by Apple as a replacement for Objective-C. It incorporates modern programming language design and borrows concepts from other languages like Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and more. Swift code is compiled with the LLVM compiler to produce optimized native code and works seamlessly with existing Objective-C code and Cocoa frameworks. It focuses on performance, safety, and ease of use through features like type safety, modern control flow syntax, and interactive playgrounds.
Kotlin for Android
Kotlin is a statically typed programming language for modern multi-platform applications that was created by JetBrains in 2011. It is fully interoperable with Java and offers advantages like concise code, null safety, and tool-friendliness. Google announced support for Kotlin on Android in 2017. The document provides an overview of Kotlin's history and features, examples of using Kotlin on Android, and recommendations for migrating code to Kotlin. It also lists various tutorials, documentation, and sample apps available for learning Kotlin.
Swift의 함수와 메소드
애플사의 새로운 프로그래밍 언어인 Swift 언어에 대해 개발자들의 관심이 커지고 있습니다. 본 발표에서는 실제 예제를 통해서 Swift의 함수와 메소드에 대해 알아보고, 튜플을 이용한 다중 변수 리턴기능과 제너릭등에 대한 재미있는 기능도 알아보겠습니다.

The Swift Programming Language with iOS App
This document summarizes a presentation on IOS 8 features and Swift development. It discusses new features in IOS 8 like battery usage indicator, interactive notifications, and healthkit. It then covers the basics of Swift syntax, how it differs from Objective-C, and sample code examples to illustrate arrays, dictionaries, functions and more. It concludes by noting some pros and cons of Swift and provides reference links for further reading.

Swift Tutorial Part 2. The complete guide for Swift programming language
Part 2 of The complete guide for Swift programming language. In this part we introduced:
Classes
Inheritance
Computed Properties
Type Level
Lazy
Property Observers
Structures
Equality Vs Identity
Type Casting
Any Vs AnyObject
Protocols
Delegation
Extensions
Generics
Operator Functions
Swift Programming Language
The document provides an introduction to Swift programming concepts including variables, constants, data types, operators, control flow, functions, arrays, dictionaries, classes, structs, enums and more. Code examples are provided to demonstrate how to declare and use variables, constants, functions, arrays, dictionaries, classes, structs and enums in Swift. Key Swift concepts like optionals, tuples, protocols and generics are also briefly covered through code snippets.
20 Facts about Swift programming language
Swift is a multi-paradigm, compiled programming language created for iOS, OS X, watchOS and tvOS development by Apple Inc. It is essentially the new go-to language for everything Apple.
We are so excited to announce that DoSelect now supports Swift programming language on our script evaluation platform! Teams can now evaluate candidates on Swift in all their tests and sessions. Developers can create solutions in public hackathons using Swift. Isn’t that so great? :)
Swift Programming Language
Swift is Apple's new programming language that can be used to write apps for iOS, Mac, watchOS and tvOS. It is an open source language that works with C and Objective-C, and provides type safety and modern language features. Playgrounds allow testing code in an interactive environment, and Swift can also be used on IBM's Bluemix platform. The language supports common data types like integers, strings and booleans, as well as variables, constants, comparison operators, loops, functions and more. Structs and classes can be used to define custom types along with features like properties, methods and initializers. Arrays, sets and dictionaries are also supported along with enumerations, protocols, extensions and error handling
Swift Tutorial Part 1. The Complete Guide For Swift Programming Language
Complete Guid for the new programming language 'Swift' for developing apps for iOS and OS X. Swift is an alternative for Objective-C language.
Introduction to Swift programming language.
Take a look to Swift, if you've been developing for iOS in Objective-C many things may look familiar, maybe just "upgraded". If you're a first timer diving into iOS development we strongly recommend you to understand first the basics of Cocoa.
Letswift Swift 3.0
The document discusses the major changes and improvements in Swift 3.0, which is expected to be released in late 2016. It outlines proposals like removing var from function parameters, distinguishing single-tuple from multiple-argument function types, and applying API design guidelines to the standard library. It also covers changes to the Foundation framework like dropping the NS prefix and making value types non-mutable by default. The goal is to enhance the Swift language, development experience, and source compatibility between versions.
LetSwift RxSwift 시작하기
RxSwift is a library for reactive programming with Observables that provide asynchronous, event-based data streams. The document discusses key concepts of reactive programming like data flows, propagation of change, and functional reactive programming. It provides examples of using RxSwift to create Observables from various sources and applying operators like map, filter, and combineLatest. Validation of form fields is demonstrated by combining Observables of text changes and checking field values and formats.

A swift introduction to Swift
A quick introduction to Swift, the new language Apple introduced in WWDC14 to create apps for iOS and OSX
Practical Protocol-Oriented-Programming
Value types are at the core of Swift (seriously, mostly everything in the Swift standard library is a value type). But how do you avoid subclassing? That’s where the power of Protocol-Oriented programming comes in. Learn how to structure your code to never subclass (almost) again! Practical everyday examples and ideas for your own code base will be included.
Swift Programming Language
Swift is a multi-paradigm programming language developed by Apple for iOS, macOS, watchOS, and tvOS. It was inspired by Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and other languages. The document discusses Swift's history, principles, syntax including variables, constants, data types, functions, closures, and control structures. It provides code examples and explanations of Swift's main features.
