Hire pre-vetted iOS Developers

What happens to your App Store submission when a reviewer rejects it two days before a funding demo? It happens more often than most non-mobile teams expect. In 2025 alone, Apple's review team rejected more than 2 million app submissions, including 1.2 million new apps and nearly 800,000 updates, out of 9.1 million it evaluated (Apple, App Store transparency report, May 2026). A generalist backend or web developer can write Swift that compiles. Getting that same code through Human Interface Guidelines review, background-mode battery limits, and a real device farm before launch day is a different skill.

Why iOS work doesn't forgive shortcuts

Cortance's iOS pool is screened specifically for native iOS delivery, not general cross-platform mobile work. That distinction matters because iOS has its own constraints. Memory management on older device tiers is stricter than most web teams are used to, and Apple's Human Interface Guidelines review rejects apps a web team would ship without a second look. Every developer we place has shipped an app through that review process at least once, not just built a prototype in a simulator.

What does years of shipping iOS apps to the App Store actually look like?

1. Severyn Katolyk has spent 11 years across iOS and Kotlin Multiplatform Mobile, with confirmed work spanning healthcare, real estate, and telecom apps.
2. Ivan Dziubenko has 8 years building iOS and macOS clients for creative, social, and Web3 products.
3. Agil Madinali, Pre-verified and based in Hamburg, has 7 years shipping iOS apps inside HealthTech and MedTech teams.

One project shows what that experience translates into day to day. Serhii Bilous, a Senior / Team Lead iOS Engineer with 10 years in Swift and Objective-C, built the iOS client for a customer engagement app for a car dealership network. The app worked as a digital customer portal, letting car owners reach the dealership and pull up vehicle information from their phone instead of calling in. It is an unglamorous problem to solve, and it is exactly the kind of app that has to keep working under real-world network conditions, past the point where a demo would end. That discipline is the same one that gets an app through App Store review on the first try.

The stack our iOS engineers work in

Our iOS developers work daily in Swift, SwiftUI, and Objective-C, with UIKit, Combine, and Core Data underneath, plus RESTful APIs, GraphQL, and Firebase for backend integration. Many also carry ARKit, MapKit, and CoreLocation for location and camera-heavy features, and XCTest for the automated coverage that catches regressions before a build reaches a reviewer. Before code reaches TestFlight, several of our engineers already run an AI-assisted review pass on top of the usual pull request review, flagging force-unwraps and retain-cycle risks a human reviewer can miss late in a sprint, which shortens the gap between a pull request going up and a build a client can actually install.

Getting iOS coverage without a six-month hiring process

1. A dedicated iOS team that owns a feature roadmap end to end, from architecture to App Store releases.
2. A single senior iOS engineer or tech lead to unblock a stuck codebase or mentor an existing team.
3. Staff augmentation for a specific release window, sprint, or Objective-C to Swift migration.

Whichever model fits, the timeline from shared requirements to a shortlist is usually a matter of days. See how hiring works at Cortance for the full breakdown. Share your iOS requirements and we will match you with vetted developers who have already been through an App Store release, beyond a coding test.
