Hi, I watched the session on how to create and add custom symbols in the SF Symbols app. Will it be possible to create localized versions of our custom symbols? Just like the system symbols that automatically substitute bases on the system locale?
Localizing custom SF Symbols
Yes system symbols use the same mechanism as you do in Xcode during the build. So yes you can localize them.
After you add your custom symbol to the Xcode asset catalog, open the attributes inspector and click the "Localize…" button. From there you, can choose which languages for which you wish to add localized variants. A slot will become available for each language, and you can drop additional symbol templates into those slots. You can also use the "Direction" popup to add a right-to-left slot, or select "Mirrored" to indicate that the image should be horizontally flipped for RTL languages.
