React Native Swift Module Singleton Pattern

If you are reading this tutorial please be aware that this is for advanced users that require a singleton pattern in their RN native module and some documentation detail is left out intentionally.

For the sake of this tutorial we will be using TestManager as our class.

Instructions

1. First of all you need to setup a swift class with a bridging header, in Xcode it will generate this for you upon creating a Swift file.
2. Create your swift class with the @objc directive.
3. Create a second class that has a static export of the class in singleton.
4. Follow the files below for a boilerplat example.

In the default React Native app scaffolding you have to edit AppDelegate.m to change where it loads the code if you want to test on your device. I use the following snippet to detect if it's being compiled for Debug or Production and for the Simulator or a device. For Production it uses a copy of the code included in the bundle, for Debug on the simualtor it loads from a server on localhost and for Debug on a device it loads from a server on a given IP address.

NOTE: You need to edit YOUR-IP-HERE and change it to the IP to load the code from when in Debug mode on a device. You could use a service like ngrok to make this work from anywhere.

  NSURL *jsCodeLocation;

  // Loading JavaScript code
  #if DEBUG
    // For Debug build load from development server. Start the server from the repository root:

# 1. Add this to your ~/.bash_profile
# 2. Relaunch Terminal
# 3. Open X number of tabs using 'tab' OR 'tab 4' etc.

function tab {
	if [ -z "$1" ]; then
		TABS=1;
	else
		TABS=$1
	fi
