Pulling a random stat out of thin air, I’d say 90% of web APIs are REST APIs. Don’t quote me on the percent, like I said, I made it up. The point is, there’s alot of data behind REST APIs and we need to know how to connect our iOS apps to get that data. In this tutorial, we’re going to write Swift code to perform a GET and a POST request.

We’re focusing on how to read JSON using NSJSONSerialization in this video. I’m putting the JSON into a file in the example code, but the real starting point for reading JSON is NSData. We’ll start with NSData if it’s coming from a URL as well.

In this tutorial, we’re going to look at the guard statement, what it solves, and why it’s better than the if.

In this tutorial, we’re going to add an event to your calendar in iOS 9 using Swift 2.0. Apple’s changed quite a bit in iOS 9 and Swift 2, so the code in this video will not work for previous versions. The constants in EventKit are a bit different as well.

In this video we’re going to talk about how to send data between view controllers using Swift 2.0. We pass information to the second view using the prepareForSegue method, and we pass information back to the calling view using the delegate pattern.

This video uses Swift 2.0 and the UIImagePickerController to access the camera. We’re also just looking at taking pictures in this tutorial. We will look at selecting photos from the photo library in another video. Our app will have a button, and image view. When the user presses the button, we’ll launch a controller to take a picture. If the user takes a picture, we’ll display it in the image view.

Today I want to share with you share extension with Swift 2.0. We’re going to write an app that lets us select an image in our photo album, and share it. A share extension is a mini app we can associate with our main app, that can run from the common share sheet.

In this tutorial, we’re going to create a video, save it to the photo gallery and our documents folder, and finally we’ll play the last video we recorded.
