Native App Development with Xcode 8 and Swift 3.0

Swift 3 is the latest and the most popular programming language used to write or create apps for Mac OS X and the iOS devices. It is also the primary development language supported within Xcode 8. Swift App Development, as a Programming Paradigm, was explicitly designed by Apple to get fast and efficient performance from devices, and Swift 3 expands upon the already present impressive features. Swift 3.0 is now available to all developers by simply downloading the Xcode 8 beta that enables you to start using the Swift 3.0 language spot on.

Xcode, with its comprehensive developer toolset, is used to create apps for Apple TV, Apple Watch, iPad, iPhone, and Mac. The Xcode development environment fastens together the Instruments Analysis tool, Simulator, and OS frameworks in the form of tvOS SDKs, watchOS SDKs, iOS SDKs, and macOS SDKs. Xcode 8 supports Swift 3 as well as Swift 2.3. With the help of a Swift migrator you can upgrade your swift code to the latest Swift 3 language specifications and SDK requirements.

Native App Development – A Short Trip

Native applications are developed for a particular platform or device. Due to this fact, they are capable of taking advantages of the respective operating system features and other software that is typically installed on that platform. They are coded in a specific programming language, such as Swift for iOS or Java for Android operating systems. In addition to providing fast performance and a high degree of reliability, they also have access to a phone’s other components such as its camera or address book. Most of the native apps can be used without an internet connection.

These native apps, however, are expensive to develop since they must be tied to one type of operating system forcing the developing companies to create duplicate versions of the app that can work on other platforms.

Xcode 8 with Swift 3.0 to Build a Native App

To develop iOS apps using the latest technologies, you need a macOS 10.11.5 or later versioned OS Mac device or an iOS device running the latest version of Xcode. Xcode includes all the features you need to design, develop, and debug an app. It also contains the iOS SDK, which extends Xcode to include the tools, compilers, and frameworks you need specifically for iOS development.

Xcode is the tool that is used to write native apps. As you start building apps, you’ll become familiar with the structure of a project in Xcode and learn how to navigate between and use basic project components. Say for example, you start making a simple user interface (UI) for an app and view it in the simulator. After you build the UI, you’ll connect this UI to the code. Working with the view controllers, you’ll implement a custom control and define your data model. You can next create a table view-based scene that lists the items. This list can become the initial scene for the app. Next, you can implement navigation, and edit and delete behavior in your app.

An important point to consider at this point of time is the persistence of data. Understanding and implementing data persistence is a substantial part of native app development. iOS, in particular has many persistent data storage solutions. One such solution is the NSCoding. It is a protocol that enables a lightweight solution for archiving objects and other structures that can be stored on disk and retrieved later.

The journey of a simple concept from the brain to the App store is not easy. With thorough practice and right processes, however, you can guide yourself in the right direction to build quality native apps with Xcode 8 and Swift 3.0.
