Combine Workshop

A workshop to get you started with the Apple Combine framework.

How to?

• Watch and listen, Antoine explains you the basics using the Combine Swift Playground
• Work in pairs of two (more fun if you don't know each other yet!)
• Ask me to verify and give feedback on your step implementation
• Implement each exercise step!

Four steps

• Connect a single UISwitch to a button enabled state
• Connect three UISwitch instances to a button enabled state
• Handle form validation
• Implement a search view to search for Swift repositories on Github

Extra exercises if you're really fast!

• Step 3: Use the asynchronous usernameAvailable() method to validate the username
• Step 3: Change the UITextField background color based on valid input to .red or .green
• Step 4: Set UIApplication.shared.isNetworkActivityIndicatorVisible to true when the request is running
