I've not been able to test this locally but it compiles in Xcode 11.2 so might work for Xcode 9.2?

When adding ~/.yarn/bin to fish_user_paths the output message was inaccurate. This also means that "Please open another terminal where the yarn command will now be available." is not accurate (it will be available immediately), although I am unsure of the best way to structure the code to alter this output.

When copy/pasting this command in fish (untested in other shells) the shell will try to expand the URL due to the ? in the URL (No matches for wildcard 'https://sentry.io/api/0/projects/[...]/processingissues/fix?_=[...]'. See `help expand`.)

This was raised in support request 22916. Colleen was kind enough to point me to this line of code.

I am not totally familiar with JSX syntax so I hope that simply adding quotes works and does not need any escaping.
