Open source libraries are those libraries which are available freely and majority of these libraries support Cocoa pods. Rather than building something from scratch, we can use these readily available libraries and frameworks in our application. This save the development time and makes the source code readable.
So lets have a small overview on some of the useful open source libraries which every developer must know of.
It a Objective-C library used for networking use in application.If you are using an API in your application then you can use this library. AFNetworking is a lightweight and fast open source networking library that uses blocks and grand central dispatch (GCD). It helps in improving the application responsiveness.
It is a Swift-based HTTP networking library for iOS and Mac OS X. It has a elegant Interface and simplifies many common networking tasks such as providing network communication for a multiplayer game, and also makes uploading, downloading, and getting JSONSresponse.
Most of the time, our iOS devices are connected to the internet and, naturally, most of the apps on our smartphones connect to a remote server to obtain some chunks of data every now and then. All of the mobile applications, nowadays, communicate with these remote servers using JSON.If you’re developing an iOS app which often requires communication with a remote server, most probably you might already getting JSON responses. This is where JSONModel library comes to help.
JSONModel is an open source library which helps to fetch JSON from server, parse it, and initialize your model classes with JSON response from the server. It also validates the JSON data. Most of the times, JSONModel is used to show response data received from API request in JSON format easily.
If you’re an iOS app developer with a design band, this is one of the useful library to be used in app.Chameleon is a lightweight, yet powerful, color framework for both Objective-C and Swift. It basically extends UIColor with beautiful, modern flat colors. It also gives an ability to create color palettes from colors defined by you.
ReactiveCocoa is rather an Objective-C framework inspired by functional programming. It helps in providing more concise and flow based code. The main reason why ReactiveCocoa known as FRP (Functional Reactive Programming) is because it combines a couple of programming styles.
Functional Programming – which makes use of higher order functions such as functions that take other functions as their arguments.
Reactive Programming – which focuses of data-flows and change propagation.
Besides this, ReactiveCocoa also offers new methods to compose and transform streams of values. It operates by using signals, which captures present and future values. More importantly, the main benefit of ReactiveCocoa is that it provides a way to deal with asynchronous behaviors, callback blocks, notifications and KVO, just by using the signals.
