Appium 2 - XcuiTest driver args unrecognized wdaLocalPort

The problem

When trying to use appium server --driver-args='{"xcuitest":{"wdaLocalPort": 8104}}' with Appium 2.0.0-beta.23 it throws the following error

appium: error: unrecognized arguments: --driver-args

Environment

• Appium version (or git revision) that exhibits the issue: Appium 2.0.0-beta.23
• Last Appium version that did not exhibit the issue (if applicable):Appium 2.0.0-beta.19 (works when i roll back to this version)
• Desktop OS/version used to run Appium: Appium 2 CLI
• Node.js version (unless using Appium.app|exe): 14.15.4
• Npm or Yarn package manager: npm
• Mobile platform/version under test: ios using xcuitest@3.59.1
• Real device or emulator/simulator: Sim

--driver-args was abandoned in favour of config schemas. These are provided by driver devs. If you have appium 2 beta and a recent version of the xcuitest driver, you can find the appropriate driver-specific flags in the help:

appium server --help

will produce this as part of the output:

  --driver-xcuitest-webdriveragent-port WEBDRIVERAGENT_PORT
                        Local port used for communication with WebDriverAgent
  --driver-xcuitest-webkit-debug-proxy-port WEBKIT_DEBUG_PROXY_PORT
                        (Real device only) Port to which `ios-webkit-debug-proxy` is connected

So you can simply run:

appium server --driver-xcuitest-webdriveragent-port 8104
