I had an app that was working just fine. And then I tried to embed the navigation controller into a tabbarcontroller and next thing I know I started getting these errors during compiling.
Would anyone know why these happen? Did some setting get unchecked or checked by accident?
Thanks, Alex
Seems your previously working code did not use ARC, now you tried to embed it into code which uses ARC ... Refactor your code using "Edit->Convert->Convert to Object-C ARC"
