What Will I Learn?
  • Part 1: Apply common filters like Sepia and Blur to the images in your app. Test distortion and transition effects! See what happens when you combine multiple filters.
  • Part 2: Use Facial Recognition software that is available in Swift to detect facial features such as eyes and smiles in photographs. Detect text found in images.
  • Part 3: Develop an interface that will allow you to load, modify, and save CIImages. Learn the different ways to load images from multiple sources into an iOS app. Knowing how to save images in a photo album opens a whole slew of possibilities!
  • Part 4: Superimpose images onto other images. Let a user place an image from a Camera Roll to the location where you tap on an app.
  • Part 5: Let a user zoom and pan on your app's images. This functionality is especially useful for users to interact with images like maps.

Why CIImages?

In this course, you learn how to add unique features to the images in your apps. A CIImage is a representation of an image that can be altered with Core Image filters. These filters allow users to change and interact with images in cool and useful ways. CIImages provide a lot of power that other image types do not.

Why Xcode? 

Xcode is Apple's FREE software for app development. Xcode is user-friendly and has the tools you need to make apps for the iPhone, iPad, Mac, Apple Watch, and Apple TV. In this course, you learn how to add User Interface (UI) elements, including text fields, sliders, and buttons, to make an app. You learn to code in Swift 3.0, Apple's programming language, to make the app function.

Is this course for me?

By taking this course, you will gain the tools you need continue improving yourself in the field of app development. You will be able to apply what you learned to further experiment in Xcode and make your own apps able to perform more.
