Xcode ligatures

Question

I am currently using Xcode 15 with JetBrains mono font. How can I disable font ligatures?

All options in Edit -> Format -> Font -> Ligatures are disabled. And none of typography section on Pref -> Themes -> Source editor options work.

Answer 1

I found no way to disable font ligature, but JetBrains Mono has its own version without ligatures called JetBrains Mono NL
