After updating xcode13, we found that the brackets and other symbols in the project are gone after running the project, and the project style is different from that of the previous OC language. Please answer the question. Thank you
After updating xcode13, there is no symbol and the style is changed,
Does the project compile ? If so, that means everything is there but not showing. Did you try to see in dark mode ?
What do you get when you copy and paste this code into a plain text editor ?
Apparently, all text in black is now white.
Go to Xcode > Preferences > themes and check what is the color of Plain Text in your theme (probably default).
