I'm not sandoze, but the figure seems reasonable for folks with 20 years of experience. Most of my buddies make about that much (plus 25% to 50% bonus) in NYC. I make slightly less than that.
I can say that I live in an area closer to the rural mid-west than NYC, and we consistently see 1-year contract rates for iOS developers in the low $200's, up to $280-300k if you have 8+ years of relevant domain experience (again 1-year contracts). If sandoze is consulting $200k is 100% reasonable. If they're a full-time employee, $200k is pretty high but definitely possible with their experience.
