Die Swift-Benutzeroberfläche bietet eine Möglichkeit, eine Vorschau des tatsächlich in der Entwicklung befindlichen Bildschirms anzuzeigen.
Zu diesem Zeitpunkt können Sie das Terminal angeben, für das eine Vorschau angezeigt werden kann. Standardmäßig gibt es jedoch nur eine Möglichkeit, es mit rawValue anzugeben. Es gibt Probleme, z. B. das Terminal, für das Sie eine Vorschau anzeigen möchten, nicht zu finden und Tippfehler zu beheben. Listen Sie daher die Terminals auf erstellt.

Wenn Sie zu [Offizielle Dokumente] gehen (https://developer.apple.com/documentation/swiftui/securefield/previewdevice(_ :)), erhalten Sie eine Liste der Geräte, die mit dem folgenden Befehl in der Vorschau angezeigt werden können.
$ xcrun simctl list devicetypes
Die obige Liste wurde erstellt, indem die Liste der erfassten Geräte mit der folgenden Methode verarbeitet wurde. Es ist unansehnlich, weil ich ein Anfänger mit regulären Ausdrücken bin, aber ...
$ xcrun simctl list devicetypes | grep -v "Device Types" | sed -e "s/\((\)\(com\.apple\.CoreSimulator\.SimDeviceType\.*\)\([0-9a-zA-Z\-]*\)\()$\)//g"
