Xcode doesn't stop asking for permissions on macOS Catalina

Oops, sorry for not answering sooner. I forgot about this thread shortly after figuring it out. Open up "Finder," go to the search bar, search "users" (also make sure that you click the "on this Mac" option too), scroll around until you eventually find a folder that reads "Users" with a simple avatar on the folder (this is important that it is not just a generic folder), click on it, click on the house that should have your name followed by "folder" (i.e. dansfolder in my case), make a new folder there and throw all your Xcode projects into this new folder. The reason why this works is because the new update basically added a complicated and often agitating new level of security to your device's documents, downloads, and desktop folders. If you successfully make a new folder under "Users" and put all your Xcode projects there, you can bypass this security feature and use Xcode normally again. This worked for me and I hope works for you too!
