My app currently needs Xcode 14.3 for compiling. But MacOS suquoia does not support Xcode 14.3. So I tried the steps previously mentioned here regarding using command line in terminal

/Applications/Xcode\ 14.3.app /Contents/MacOS/Xcode

but it kept on saying, permission denied. Then I tried adding administrative privileges to my command using

sudo /Applications/Xcode\ 14.3.app /Contents/MacOS/Xcode

Now it kept on saying , command not found.

So I found another way to run XCode 14.3 in my mac. Once you unzip the XCode 14.3 and put it on applications folder it is not going to run it directly. You right click the XCode 14.3 > Show package Contents > Contents > MacOS > XCode and run it. It will direct the terminal and run the Xcode for you. From there you open file>Settings>Locations. And in there in command line tools you select XCode 14.3.
