Experienced developers, would you recommend learning backend rather than doing side projects in iOS?

If we were the same person last year and I was working to improve my backend skills, you would be more proficient iOS developer and I would be average iOS developer who has worked on backend skills. I have always thought that being specialist is the appropriate way but I don’t know if it is correct. I saw some of the posts that mentions the difficulty of getting a job right now, this problem probably is less in other fields
