"Awesome class for really learning how to setup and implement MapKit in your iOS apps using swift. Def. one of the best classes I've taken on Udemy. Looking forward to more classes offered by Mohammad Azam. A++ class"

Why learn JSON Parsing?

An iOS app is not an island, an app is constantly communicating with a Web API to fetch or submit information. Consuming a JSON API is an integral part of any iOS application.
By learning the concepts of JSON Parsing in iOS, you will be able to consume third party APIs including News, iTunes, Movies, Real state properties etc.

Who is this for?

This course is for anyone who wants to take their skills to the next level. JSON Parsing is an integral part of iOS app development and it allows your app to easily consume information from third party sources. This course is intended for intermediate developers, who have knowledge of iOS app architecture and Swift programming language.

Is this course right for me?

Look: if you are still not convinced then I urge you to check out my 5 star reviews in other courses. I am a well known developer in the iOS community with a large following. I do a lot of speaking engagements in which I spread knowledge and education.

What are the requirements?

A Mac Computer
Xcode 9.3 or above
Understanding of iOS framework is required
Basic understanding of the Swift language and the iOS SDK - I'll teach you everything you need to know about JSON Parsing in Swift.

What am I going to get from this course?
