Why we read it this way (7)
A bachelor's degree is mentioned as 'a good foundation' but the posting explicitly states equivalent job-related experience is acceptable, so no hard degree requirement is set.
Swift and Objective-C are listed as a proficiency pair ('Swift/Objective-C') in the competencies section; Swift is the clear primary language and Objective-C is treated as an alternative.
UIKit, SwiftUI, and Combine are listed together as examples of 'modern iOS frameworks' in the qualifications block and are treated as separate hard-gate skills.
React Native appears in the Additional Information section alongside a portfolio/work-samples request — it reads as a secondary gate or strong preference rather than a core requirement, so it is marked preferred.
The broad 'supporting technologies' block (Node.js, PostgreSQL/Oracle/MSSQL, AWS, containerization, CI/CD, shell scripts, API design) is explicitly framed as background context ('you won't necessarily be working with these every day') and is therefore marked preferred.
Supervisory/management experience is called 'a plus' and is a soft skill rather than a named technology, so it is omitted from the skills list per extraction rules.
The role requires Philadelphia city residency within six months of hire — a notable constraint not captured in any structured field.
