Setting Up an iOS Environment

This guide sums up the tools required for an environment for running automated UI tests using iOS simulators (using Detox, in particular).

Prerequisites

Running Detox (on iOS) requires the following:

macOS Catalina and above
Xcode 11.0 and above, with Xcode command line tools installed
- Xcode can be installed from the App Store, or downloaded directly from Apple Developer

Homebrew is a package manager for macOS, used to install other command line tools.

To ensure everything needed for Homebrew tool installation is installed, run

xcode-select --install

A collection of utils for Apple simulators, Detox uses it to query and communicate with the simulator.

brew tap wix/brew
brew install applesimutils

Note: Make sure to periodically update your version of applesimutils to the latest version.
