I just updated Xcode to 12.4 on MacOS 11.2 (MBP 15-inch, 2017 16GB RAM). and Xcode has been crawling ever since, simply selecting a view or a storyboard will cause Xcode to hang for 45 seconds to 2 minutes. Sometimes I can type more then 10 characters before the editor hangs for about a minute.
This is brutal, literally 2 days ago this was not an issue, just immediately after the update.
Is anyone seeing similar results? I am hoping its just the combo of versions
