I am still in the process of trying to learn Swift, so I can make apps.
I found a tutorial, that uses Swift 5.3, but am fully aware that 5.4 is the newest version available.
Can I still use tutorials that reference older versions of the programming language, or do they have to use the newest version?
Also when in Xcode, voiceover says, "no editor" then if I scroll down a little, it says, "add editor on right" so, i clicked on it, but nothing happened.
Do I need to add an editor to Xcode? If yes, how do I do it?
Any & all advice is greatly appreciated.
