Hi! @amartini51
Could you please review this PR? I haven't received any reviews for a month.

[amartini51]

@Jager-yoo I think you haven't gotten any review because you didn't request any reviewers. On the GitHub pull request page, the reviewers is at the top of the right-hand column. I work on the documentation, so I'm not really the right person to review this code change.

@jckarter or @lorentey Could one of you take a look, or suggest a reviewer?

[Jager-yoo]

@amartini51 Sorry about that, I just can't assign reviewers because I'm not one of Apple team members.
Next time, I'll ask the right person. 😅

Sorry about that, I just can't assign reviewers because I'm not one of Apple team members.

Sorry, I didn't know only Apple team members could assign a reviewer. Thanks for letting me know. I've assigned Karoy as a tentative reviewer, and I'll let him re-assign as needed.
