To run the companion app on iOS or test it in an iOS simulator, you'll need a Mac.
There will be a few things to install:
* Xcode
* A Simulator runtime
## Installing Xcode and simulators
Install Xcode from the App Store. When you launch it, you should be provided with a dialog that lets you install simulators for your preferred iOS versions. Otherwise, you can add/remove simulator runtimes here:
* Xcode > Settings > Platforms
Apple has a more in-depth guide [here](https://developer.apple.com/documentation/xcode/installing-additional-simulator-runtimes) regarding installing simulator runtimes.
## Setting up the Project
Once you've done that, you can follow the guide on [building and signing iOS apps](Building%20and%20Signing%20(iOS)) as it shows you how to open the project and set it up in Xcode.
If you are developing locally and aren't yet ready to test the app in production, make sure you set `dart.env.prod=false` in the .env file, so it connects to your local servers rather than the production servers.
## Testing on a physical iOS device
Apple has a guide [here](https://developer.apple.com/documentation/xcode/running-your-app-in-simulator-or-on-a-device) for setting up Xcode and your device to build and test apps on your iOS device.
