I have 9 plus years of iOS experience starting with Objective C and moving to Swift, but after 4 years in my current company with little salary growth, I am struggling to find new opportunities in a highly competitive market with fewer openings and broader skill expectations. I am unsure about the long term career path for mobile developers, concerned about compensation growth and lacking SwiftUI experience, and would appreciate guidance on what additional skills to learn to stand out and secure better opportunities.
