Why we read it this way (6)
The 12+ years requirement is stated at the role level ('12+ years of experience with native iOS development') and is treated as the overall experience floor; it is also reflected on the iOS skill's years demanded since it is explicitly tied to that technology.
SwiftUI and UIKit are listed together as alternatives in the Required section ('SwiftUI, and UIKit'); either satisfies the requirement.
MVVM appears in the Responsibilities section as an architectural pattern to adhere to ('architectural patterns (e.g., MVVM)') — included as a required practice given the firm gating language of that section.
Agile methodology is mentioned under Preferred Qualifications but names no specific tool (e.g., Jira, Rally), so it was omitted per the no-generic-concepts rule.
Wealth management / asset management domain knowledge is listed under Preferred Qualifications but names no concrete technology, so it was omitted.
No compensation figures are provided in the posting.
