How can I move everything related to Xcode to external drive?

I have a latest MBAir with only 256Gb which is a relatively small amount of space. I'm working in Xcode and it ate about 60Gb of space on my Mac. I have successfully tossed the .app itself and relocated the 'DerivedData" and "Archives" to the external SSD but there are still plenty of gigs lying in /Users/myname/Library/Developer. At least there are Xcode/UserData which takes 15Gb and CoreSimulator which takes additional 15Gb. It's not everything, there is about 20 more gigabytes but I want at least to move these. How would I do so?

I'm literally looking for the same answer. Did you ever find anything? Also, what app is this to show you used space? looks very useful to purge
