Building an iOS Device Farm from scratch
summary
A complete open source iOS device farm is built from scratch that runs on macOS and Linux, captures live video by decoding the device AVFoundation H.264 stream into fast JPG frames, and remotely controls input by calling a private xc test function (synthesizeEvent) for low-latency taps. It integrates with Appium/WebDriverAgent, uses libimobiledevice tools and go-ios reverse engineering to deploy apps and run parallel XCUITest sessions, and is already in production use by multiple companies.
