About

Apps that don't save any data are no fun. A grocery list app that doesn't save the user's list is useless. A game that doesn't save a user's high score has no challenge. In this course, you will learn how to save data in iOS in two important ways, with CoreData and with Realm.

Core Data is a data-saving framework built by Apple. If you want a job as an iOS developer it is essential that you have this skill on your tool-belt. Core Data allows you to save whole objects into a datastore of your choice (though more often than not you will use a database). Then you can retrieve these data objects when you want. To learn this skill you will create a to-do list app.

The next way to save data is using a tool called Realm. Realm is an open source, a third-party database that is much simpler to set up than CoreData. We will cover the pros and cons of using Realm and how it can make your applications better.

Style and Approach

This video is a step-by-step guide to helping the audience get started with iOS application development by providing a solid foundation in the core iOS concepts, techniques, and the Swift programming language. With every part of the course packed with practical examples, you'll understand how iOS development works, the latest features of iOS 11, and when and where to apply the core iOS techniques.

Features
  • Save data into an iOS app that can be retrieved later.
  • Create a fully functional to-do list application.
  • Learn how to install Realm and use it for your data needs.

Nick Walter

Nick Walter - Mobile and Web Developer - iOS, Android, Django, Python. etc He loves to code. About five years ago he decided that he wanted to learn to code, but he had limited access to programming resources, and he was getting frustrated with all of the YouTube videos and online tutorials out there. He experimented, struggled, and definitely failed a lot, but he finally got the hang of it, so he decided that he wanted to change the way that people learned to code, and he started teaching. His experience as an online student has directly influenced his teaching style because he knows what it is like to be in your shoes. When Apple announced its new programming language, Swift, in 2014, he made his big online teaching debut and created the internet's first Swift course. Since that time, he has become a full-time online instructor and he now has courses not only in Swift, but also in iOS, Android, Django, Kotlin, Python, HTML, Blockchain, etc. He had also created five iOS apps from scratch that are currently live in the App Store and are being used by thousands of users worldwide. He love's sharing his excitement for coding with his students, and he did try to make learning as fun and as easy as possible. Thanks for being part of the coding community!
