Becoming an efficient iOS Developer

1. Efficient language

There are a number of factors to take into account each-time we start a new mobile project, whether to use Swift or Objective-C for development isn’t always a clear-cut decision. Selecting the most appropriate language depends on the project and team context, as well as preference to a particular programming language. Swift takes a lot of useful components from Objective-C while also bringing a whole new host of features, allowing developers to write safer, more reliable code. It has quickly become the leading programming language for creating engaging, user-friendly mobile apps.

2. Efficient Programming

A design pattern is a general repeatable solution to a commonly occurring problem in software design. MVC,MVVM or VIPER Which architecture is the best? Lets decide,

Model-View-Controller architectural pattern, which is best suited for simpler applications.Next one the MVVM design pattern is an improved version of MVC. In MVVM, the View and Controller are united to form a view with an additional introduction of ViewModel, which now handles the presentation logic.Also, VIPER defines the better separation of concerns than any other architectural design pattern such as MVC, MVP or MVVM which makes test-driven development more easier

3. Efficient Performance

If we are going to create responsive and snappy apps with buttery smooth animations and transitions, so GCD are definitely something we should master. Swift has made a move into a more elegant object-based way of coding concurrency, that allows you to keep your code dense and at the same time have control over when your code is executed.Since Swift 3, Grand Central Dispatch is object-oriented.

Grand Central Dispatch is a wrapper around creating threads and managing that code. Its emphasis is on dispatching, i.e. making sure that a number of tasks of variable importance and length are executed in a timeframe as reasonable as possible.

4. Efficient UI Design

The reason for the popularity of most of the iOS apps is intuitiveness. Design app which is,

• Easy to operate
• Clear navigation structure
• Ensure the integrity of the aesthetics
• Highlight the primary function
• Use simple terms
• Consider the direction (users sometimes like the horizontal mode, sometimes like the portrait mode when they operate the device)
• Make sure the touch point is suitable for fingertip size

5. Efficient Networking

Every app is connected to the web, thus making networking an important aspect. To understand the process of sending and receiving data over the web, one needs to be familiar with JSON i.e. JavaScript Oriented Notation. As we know HTTP network requests living at the heart of mobile applications that make the magic happen. To help you with the numerous requirements for network requests, Apple provides URLSession, a complete networking API for uploading and downloading content via HTTP.

Although writing networking code can be easy, for all but the most trivial networking needs, writing good networking code is not.

Several engineers argue that AFNetworking has become a fancy wrapper for the powerful NSURLSession. We we have to make best fit decision here also.

6. Efficient Data

One of the aspects you must figure out is how to store and search for large amounts of data, so you’ll probably use a database. The most common options for iOS databases are SQLite and Core Data and a relatively newer player called Realm.SQLite is the most used database engine in the world and its open source as well.Core Data is the second main iOS storage technology available to app developers.

If you are designing an app with a lot of records and for a large number of users, you need to pay special attention to scalability from the very beginning. 

7. Efficient Libraries

Libraries can make your life so much easier when you are coding for iOS. With all of the work that Apple has put in to make programming for iOS as easy as possible, there is still a lot of room to be able to use third-party tools to improve your code quality. Here are the best libraries in Objective-C and Swift.

• AFNetworking/Almofire
• SwiftyJSON
• MagicalRecord
• SDWebImage
• ReactiveCocoa
• PLCrashReporter
• iRate
• ObjectMapper
• Appium
