# run-ios

## Description

* Runs a MiniApp on an iOS emulator or connected device  

## Syntax

`ern run-ios`

**Options**

`--dev [true|false]`

* Enable or disable React Native dev support

  `--miniapps/m`
* One or more MiniApps to combine in the Runner Container

  `--dependencies, --deps`
* One or more native dependencies to add to the Runner Container

  `--descriptor, -d`
* complete native application descriptor

  `--mainMiniAppName`
* Name of the MiniApp to launch when starting the Runner application

  `--usePreviousDevice/-u`
* Use the previously selected device to avoid prompt

`--host`

* Host or ip to launch the local packager on *(default: localhost)*

`--port`

* Port on which the local packager should listen on *(default: 8081)*

## Remarks

* You can launch the MiniApp located in the current working directory or on a connected iOS device or running emulator if available. If a connected iOS device is not available, the command prompts you to select an emulator to launch from the list of installed emulator images.  
* The first time you run this command from within a MiniApp directory, it generates an iOS directory containing the iOS Runner application project. If the iOS folder already exists (it is not the first run of the `ern run-ios` command for this MiniApp), the existing runner project is used.  
* After the runner project is generated, you can safely make native code modifications to it, knowing that the next time the `ern run-ios` command is issued, the project and your changes will remain.  
* If you want to regenerate the runner project from scratch, remove the iOS directory.  
* The miniapp can be any Yarn package descriptor, including Git or other file system path schemes.  
* The `ern run-ios` command is the `ern` equivalent of the `react-native run-ios` command.
