Can't get appium server logs on iOS

[gadgadskiy]

Hi all. Now I have problem with getting Appium server logs running on iOS devices.
For getDriver().manage().logs().get("server") I got error Appium error: An unknown server-side error occurred while processing the command. Original error: Unsupported log type 'server' for this device.
I can get “syslog” logs by it isn’t that I want. I need logs about session processing.
showIOSLog=true capability is provided on test start but it doesn’t help to.
Is there any way to get Appium logs on iOS like the “server” logs on Android?

Make sure the server is up to date
