In 2018, Valve announced the Steam Link app for iOS for streaming PC and Mac games, but the program was not allowed on the App Store . Now everything has changed.
The company still released the application, it is completely free and works with iPhone, iPad and Apple TV.
This is what the Steam Link app looks like.
With it, you can remotely run games from your Steam library. Important condition: the iOS device must be on the same Wi-Fi network as the computer. It is recommended to use a router with support for 5 GHz.
There is support for Steam Controller, so you can play from your smartphone using the Valve gamepad. This is better than using on-screen buttons. [ MacRumors ]
