I was looking for my app's Application Support folder and was confused to see hundreds of folders with names like 36FE5C78-6D16-4556-8F13-80B0F2E7AD4B-84238-0000088F9B63C05B cluttering the Data folder. Some of these folders are empty, some contain a file named something like 791DC593-238F-4180-9D5D-6ABB7D22A4D3-18720.profraw.
It seems that whenever I run any of my tests in Xcode, a new folder is generated and all the old ones are never removed. What's the purpose of these folders and why are they not removed automatically?
