## Beschreibung mittels Docstring { #description-from-docstring }

Da Beschreibungen oft mehrere Zeilen lang sind, können Sie die Beschreibung der *Pfadoperation* im <dfn title="Ein mehrzeiliger String (keiner Variable zugewiesen) als erster Ausdruck in einer Funktion, wird für die Dokumentation derselben verwendet">Docstring</dfn> der Funktion deklarieren, und **FastAPI** wird sie daraus auslesen.

As descriptions tend to be long and cover multiple lines, you can declare the *path operation* description in the function <dfn title="a multi-line string as the first expression inside a function (not assigned to any variable) used for documentation">docstring</dfn> and **FastAPI** will read it from there.

If you have multiple devices connected, specify the device UDID with the GOIOS_DEVICE_ID
variable. Use `idevice_id -l` to list all available UDIDs. Then, setting GOARCH to arm64
will select the device:

	GOOS=ios GOARCH=arm64 CGO_ENABLED=1 CC_FOR_TARGET=$(pwd)/../misc/ios/clangwrap.sh ./all.bash
