mobium launch
This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET
Bring an app to the foreground
Usage
mobium launch <package | bundle-id> [flags]
Flags
| Flag | Type | Default | What it does |
|---|---|---|---|
--gray-box | bool | Launch the app with Mobium's gray-box library on, so every action waits for the app to say it is idle (docs/guides/graybox.md) | |
--hit-test | bool | On an iOS simulator, load the hit probe into the app as it launches, so every tap on an element in it asks UIKit where the touch goes first (docs/guides/autowait.md) |
And the global flags.
