You're suggesting less than 100 for iOS Dev, and above you someone is suggesting 150+ for devops/sysadmin.
That ratio seems quite skewed compared to other sources of data on the web.
Are you very junior, or talking about a non-prime job market/locality?
A little bit of both (I've been doing iOS for less than a year), but mostly the latter. I don't live near a tech hub or major city, and the cost of living is pretty low. So good data was hard to come by. I essentially just found the range for the closest major city and went from there, taking into account what I wanted with how the current market was going (salaries here are generally 20-30% lower than the major city, while the cost of living is much less).
