How to type this ß (Eszett) or weird-looking "B" as I knew it before in Mac and iPhone.
The "s" needs to be lowercase.
alt/option/⌥ + s
Using the German Keyboard: here is how to add new keyboards.
hold down "s" and choose it from the list
This is how it's going to look if you hold down the key on a uppercase "S".
Here is if you hold down lowercase "s".
Why is this weird-looking "B" under "s" instead of "B", well in fact it is because is an actual "long s" sound, also called sharp s.
What am I doing with this?
I started to seriously learn German, well, using Duolingo, Duolingo-serious, and while I have been using the app it never gave me a wrong answer using "u" instead of "ü" or "b/B" instead of "ß", but it started to giving me this as a wrong answer.
Notice the lowercase "s" in Schokolade.
