Accepting license agreements isn’t standard because EULAs aren’t standard. Each one is a contract and each one is unique.
Just because you click through them all without reading doesn’t mean they are all equivalent. Xcode has an EULA. Swift and Make do not, being free software.
They are not the same.
I think any using Swift CLI tools would be bound to the same EULA as the Xcode CLI tools. I worked with a german developer that did all his Xcode work in emacs with GCC in Objective-C days. Somebody like to stand on ideals and complain and others like to get work done.
