As soon as you know the basics, you set the foundation for growth. It works the same way for any job and there is no secret that many significant innovations are still grounded on diverse knowledge boosting the potential and force of creativity. So, today let’s do our homework on the basics and add one more article to the set of the professional glossary. Earlier we have already published the Glossary posts with key terms for the topics of UI\/UX design<\/a> and web design<\/a>\u00a0as well as business terms<\/a> and abbreviations<\/a>. This time the perspective will get changed a bit, featuring the first set of terms in the theme of iOS development. Let’s get started briefly reviewing the basic notions common for the sphere of iOS development.<\/span><\/p>\n

iOS<\/span><\/h2>\n

Basically, widely known iOS is the well-established abbreviation taking its roots from the phrase “iPhone Operating System” which was created originally for the system of mobile devices produced by Apple such as iPhone, iPad, and iPodTouch and now also AppleTV.\u00a0<\/span><\/p>\n

User interfaces created for\u00a0iOS are made on the basis of\u00a0direct manipulation involving multi-touch gestures. Interface control elements present a variety of functions and forms including\u00a0buttons, sliders, and switches. Gestures taking place in the process of interaction with such type of interface are also various, for instance, swipe, tap, pinch, and reverse pinch; what is more, they all have specific definitions in the context of the iOS operating system. Some\u00a0iOS applications even use internal accelerometers which can react to the cases of shaking or rotating the device in three dimensions. Another typical feature is portrait and landscape mode switching.<\/span><\/p>\n

From the standpoint of development, Apple gives steady preference to simple and durable things, and this concept is applied to their products, applications<\/a>, tools, and frameworks. It is expected that when an iOS developer builds an app for iPhone, it will run on any other device with iOS. This aspect of iOS development can save a large amount of time for programmers as writing code, let’s say, for iPhone, the developer uses the same programming language for all Apple\u2019s computing devices. Said otherwise, an application created for iPhone can later be even integrated into Mac.<\/span><\/p>\n

In both UI\/UX design and development for iOS, specialists making screens and writing code, apply their flight of creativity in terms of definite rules and guidelines to keep. The apps which don’t keep those guidelines risk failing to submit their app to the Apple ecosystem of devices. Working on the digital products intended to be used in iOS, professionals need to know iOS Human Interface Guidelines<\/a> and always keep an eye on updates and fresh recommendations. The set of guidelines for designers states: “As an app designer, you have the opportunity to deliver an extraordinary product that rises to the top of the App Store charts. To do so, you’ll need to meet high expectations for quality and functionality”. Actually, the same position works the same way for developers who are offered samples, guidelines, and support to find the optimal solutions for user-friendly and effective digital products.<\/span><\/p>\n

iOS architecture<\/span><\/h2>\n

As it was mentioned before, iOS allows users to interact with their devices and products using gestures such as swiping, tapping and pinching. These finger actions are typically performed on touchscreen displays, which provide fast response and accept inputs from multiple fingers. <\/span><\/p>\n

The iOS architecture can be pictured as four abstraction layers that define it:<\/span><\/p>\n

Cocoa Touch.<\/strong> The layer containing a variety of frameworks that define the appearance of the app. It also provides the basic app infrastructure and support for main technologies such as multitasking, touch-based input, push-notifications, and many high-level system services.<\/span><\/p>\n

Media.<\/strong> The layer with graphics, audio, and video technologies that developers use to implement multimedia experiences in the apps. The technologies in this layer make enable building apps that look and sound excellent.<\/span><\/p>\n

Core Services.<\/strong> The layer consists of essential system services for apps. The main services are the Core Foundation and Foundation frameworks, which define the basic types that all apps use. It also contains individual technologies to support features such as location, iCloud, social media, networking, etc.<\/span><\/p>\n

Core OS.<\/strong> The layer including services such as security, local authentication, and core Bluetooth frameworks.<\/span><\/p>\n

Apple recommends developers to write code to the highest applicable layer whenever possible, and only use the lower-level frameworks for features not exposed at higher levels.<\/span><\/p>\n

Architecture design patterns<\/span><\/h2>\n

In software development, an architecture design pattern is the matter of structure. It is not a finished architecture that can be transformed directly into code. Patterns are similar to the case of reliable practices that the developer can use to solve common problems building an application or system.<\/span><\/p>\n

In general terms, architecture pattern in the case of development could be described as a reusable solution that could be repetitively applied to the issues that frequently arise within a particular context of development and engineering interactions. This sort of patterns takes into account various limitations and restrictions including the problems of hardware performance, availability, the environment of use, and even particular business goals.<\/span><\/p>\n

Among the main architecture design patterns we could mention:<\/span><\/p>\n
