How to Make a Custom Control Reactive With RxSwift

Author: Bart Jacobs

Earlier this week, I showed you how to create a custom control using a bitmask. But it's time to take it one step further by adding RxSwift to the mix. In this tutorial, we make the custom control we built reactive using RxSwift.

Cloning the Repository

Head over to GitHub and clone the project if you'd like to follow along. Open Terminal and execute the following command.

git clone git@github.com:bartjacobs/HowToCreateACustomControlUsingABitmask.git

Adding Dependencies

You can add RxSwift one of several ways. I prefer CocoaPods. Navigate to the root of the project and execute the following command to set up CocoaPods for the project.

pod init

Open the project's Podfile in your favorite text editor and add RxSwift as a dependency.

target 'Schedules' do
  use_frameworks!
  platform :ios, '10.0'

  pod 'RxSwift'
end

From the command line, execute pod repo update to make sure the specs repositories on your machine are up to date. To install the dependencies, execute pod install.

pod repo update
pod install

This tutorial uses version 3.4.1 of RxSwift. Open the workspace CocoaPods has created for you and trigger a build by choosing Build from the Product menu. You shouldn't see any errors or warnings.
