Our 20th meetup: Saving data in iOS apps, part one

It’s our 20th meetup! Join us as we continue to explore iOS development in Swift.

• What we'll do
This will be the first of a couple of sessions where we’ll look at various ways in which your iOS apps can save data for later use. This session will cover the simpler approaches to saving data, namely:

• Saving settings and other small data with UserDefaults
• Saving larger data to the file system
• Saving formatted data using codable types, property lists, and JSON

We’ll use these capabilities to build a simple task list app, which you can use as the basis for your own apps.

• What to bring
This meetup will be a “code along with me” exercise. That means you’ll need to bring a Mac laptop with Xcode 9 installed. You’ll probably also want to bring an iOS device along, although this exercise should run just fine in the Simulator.

• Important to know
Nobody learns well on an empty stomach, so we’ll provide pizza, soft drinks, and water, courtesy of my employer, our venue-provider and sponsor: Sourcetoad!
