 In Mac OS X 10.6 only Swiss French and Swiss German is available and on iPadOS the Swiss German layout is not supported for and language other than German.On Windows, Swiss German does not include the esszett (ß) ligature, which is only used in Germany and Austria, meaning that that letter is unimportant in Switzerland, and is therefore not found on the keyboard.Linux typically assigns ß to AltGr-s.
