I am new to Apple development, and I'm working on a first, basic iOS app. I am trying to use XCode 12.4 but it's very hard to find documentation. Everything I've found, including commercial tutorials and even the doc here at developer.apple.com, shows versions of Xcode that don't look anything like mine. While it's not that hard to figure out the differences in the code editor, the Interface Builder is so different that a beginner has nothing at all to work with.
Is there updated doc somewhere that I just haven't found, or do I need to revert to an earlier version of Xcode?
