I couldn't replicate your issue. The error import: command not found indicates that the import statement is being interpreted as a shell command rather than a valid Swift language construct. This typically happens when you try to execute a Swift script using a shell interpreter.
You should make sure that swift is installed (execute swift --version). Executing swift export-safari-bookmarks-new.swift is correct, it works on my system.
