$150,000 is normal for around 10+ years experience, if your exceptionally well ( can do UI/UX, networking, automated testing, web, systems, bash and Script Editor scripts, along with Xcode plugins/extensions and tools to automate and optimize the production pipeline aka the full stack and lead/mentor other developers to bring them to a high professional level) then $200,000+ is normal, but very rare to find. Note, you can normally do all these things in swift and objective-c, know the internals, security and architecture differences between the last three phones released and how to optimize your code for them.

Also note this normally only applies near big metro areas (35 mile radius) like Washington DC, New York, LA/Bay Area, San Francisco, Cupertino, Houston/Dallas, maybe Miami and/or where ever the headquarters are for the large companies. Outside the U.S. the salaries are probably lower as the demand for top talent is lower.

Interesting, thanks for the details. I'm in San Francisco bay area and thought $150k would be the "bottom" for big companies.

Nope, it is very regular to get that as a salary, you normally make up for it in San Fransicso and other big areas via bonuses, stocks, 100% or close to 100% paid benefits, company paid transit/parking/meals/schooling and other adds-ons were their actual financial monetary value far exceed your cash salary.
