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:

Mac with macOS (at least macOS High Sierra 10.13.6)
Xcode 10.2+ with Xcode command line tools. Xcode can be installed from the App Store, or the online Apple developers page (requires a valid Apple ID to login).

Tip: Verify Xcode command line tools is installed by typing gcc -v in terminal (shows a popup if not installed)

Homebrew is a package manager for macOS, we'll need it to install other command line tools.

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

xcode-select --install

Tip: Verify it works by typing in brew -h in a terminal to output list of available commands

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

brew tap wix/brew
brew install applesimutils
