Best iOS Libraries for Developers

 In CloudRail

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.

What tools? Well:

Animation Libraries

API Libraries

CloudRail: CloudRail (our own iOS solution) is a library that allows you to access a range of Cloud Service, including Dropbox, Instagram, Twitter, Drive, etc. What is particularly cool about CloudRail is that when you use multiple services in the same interface/category, e.g. Dropbox and OneDrive, all of the methods and functions are shared between the services. So a single, unified API across multiple services

UberKit: Allows your iOS application to connect up to the Uber API, allowing you to book taxis for people, let people access their accounts, etc. What is particularly great about Uber as an API is that they offer a bounty. If your user books a cab using Uber, you get an affiliate marketer revenue for this transaction being from your API
