It is called Minimap. It becomes useful when having several lines in code in your file since it provides a visual guide of the whole content of the file, but strangely, your looks bugged since it appears empty. It should look like the picture of Claude31. Try restarting Xcode or toggling Minimap from the Editor Options Button (the one you use to enable your canvas).

Hello, have you checked if the Documents directory appears on your iCloud? The situation you say seems a lot similar to when you let iCloud Drive store the Documents and Desktop files on the cloud. Cheers, Franz

Update: Found other discussions about the same topic, so nothing new with the workaround. Anyways, hope the thorough explanation results useful for someone. In these other discussions, someone mentioned that for Xcode 13.2 the usual behavior is back. Xcode 13.1: What happened to shortcuts on international keyboards? Xcode 13 key bindings problems

Hello, today I had the same problem after updating the OS to Monterey. Here is how I solved it. First, the characteristics of my set-up were as follows: Xcode version: 13.1 (13A1030d) OS: macOS Monterey 12.2 Keyboard input: Spanish Latin American Keyboard physical Layout: ANSI US English (of MacBook Air bought in Japanese market) The problem occurred when trying to "comment" a section of code. But the usual key combination of Cmd + Shift + 7, which was always interpreted as Cmd + / did not work. So for the explanation, I will treat the case of the key binding "Cmd + /" not working in my not-US keyboard input. Solution: 1 . In Xcode -> Preferences -> Key bindings search: command / to find all commands associated with the key combination. 2 . Change the key combination of one of the 4 occurrences to any combination you wish (The rest will update automatically when you click outside of textbox). This will modify the Key bindings file on your computer. Doesn't matter if you cause a conflict. 3 . Close Xcode and open the Defaults.idekeybindings file in the directory (user)/Library/Developer/Xcode/UserData/KeyBindings with your preferred text editor. (Library directory is hidden. If you want to access from Finder press Cmd + Shift + . to see hidden files). 4 . In the file content we can see 4 < dict > structures and in each of them, inside one < string > tag is the key combination we entered previously. The codification is easy to understand since "$" resembles S from Shift and "@" has curves like the Cmd symbol. I assume this documentation is still valid, so the rest special key's codes should be "^" and "-". 5 . Replace the key combination in every < dict > structure for the literal key combination you have always used. In this case, I will insert Cmd + Shift + 7 in that order since Shift + 7 is interpreted as "/" everywhere (but when combining with Cmd in Xcode). 6 . Save the file, exit the editor, open again Xcode and you should have your key combination working! NOTE: If you wondered why I did not simply insert the combination Cmd + Shift + 7(number) in the Key binding window is because if I type that combination, Xcode will register Shift + Cmd + / instead. Definitely is something they have to correct since ONLY for the case of typing Cmd + Shift + 7 (Cmd + /) and Cmd + Shift + 0 (Cmd + =) the program decides to register this other pattern. For the rest of the numbers, it will register the combination correctly! E.g. if I want to register Cmd + &, with my keyboard I have to type Cmd + Shift + 6, and in the Key Combination textbox it will appear Cmd + & as anyone would expect! Weird behavior. Trying to register Cmd + / : Registering Cmd + & : NOTE 2: I will check how to report this and possibly have an explanation of this behavior or a reply taking on the commitment to fix this. Because users having to make workarounds for this kind of sudden change in behavior of a program you have used daily is really a pain in the neck and today I interrupted the flux of my work to get Xcode to work as before.
