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)

  --launchArgs

• Arguments to pass to the application when launching it (correspond to the Arguments Passed On Launch in application scheme run config in XCode as can be seen on screenshot below).

• Make sure to use = on the command line to provide this option, and keep the string in quotes. For example --launchArgs="-ArgA -ArgB"

--launchEnvVars

• Environment variables to pass to the application when launching it (correspond to the Environment Variables in application scheme run config in XCode as can be seen on screenshot below).

• Make sure to use = on the command line to provide this option, and keep the string in quotes. The string should contain key=value pairs delimited by spaces. For example --launchEnvVars="aKey=aValue anotherKey=anotherValue"

xcode scheme run

--mainMiniAppName

• Name of the MiniApp to launch when starting the Runner application

--miniapps/m

• One or more MiniApps to combine in the Runner Container

--port

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

--usePreviousDevice/-u

• Use the previously selected device to avoid prompt

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.
