Hire pre-vetted Objective-C Developers

Anyone can open an eight-year-old .m file and patch a crash before lunch. Keeping that codebase alive for another eight years, moving pieces over to Swift without breaking App Store review or the features paying customers already depend on, is a different skill entirely. Most Objective-C hires today are not writing new screens. They are the reason an old one keeps working.

What eight years of Objective-C in production actually looks like

Serhii Bilous, a Senior iOS Engineer and Team Lead with ten years of Objective-C behind him, spent part of that career as iOS Team Lead on a secure document platform built for a US law firm. It was an enterprise-grade app that gave attorneys and legal staff real-time access to case files and internal systems from an iPhone or iPad, the kind of build where a broken permission check or a failed sync is not a cosmetic bug but a compliance problem. Mychailo Symonenko, a Verified Senior iOS Developer, inherited an existing banking app built for corporate clients under NDA. His job was not a rewrite. He refactored code he did not originally write, fixed what was broken, and added new KYC features on top of it. That is closer to the real job description for most Objective-C hires: take over something that already works for paying customers, and do not be the person who breaks it while making it better. Every candidate we put forward is screened specifically for that kind of legacy-ownership experience, not just Objective-C syntax, through Cortance's vetting process.

What's actually inside a Cortance Objective-C developer's toolkit?

Our Objective-C pool covers the parts of the platform that do not show up in a job posting until something breaks: Cocoa and Cocoa Touch, UIKit and Foundation, Core Data and Core Animation, AVFoundation, and the multithreading and memory management patterns that keep an older app from leaking its way into a one-star review. On projects where a migration touches dozens of files at once, some of our engineers lean on AI-assisted code review to flag risky patterns before they cross the bridging header into Swift, which catches regressions earlier without slowing the actual rewrite.

1. Native iOS and macOS development across Cocoa, Cocoa Touch, and Core Data
2. RESTful API integration and third-party SDK or payment gateway work
3. Interoperability with Swift, including bridging headers and mixed-language modules
4. App Store submission, release workflows, and post-launch stability fixes

Build the team that fits your stage

A startup maintaining a legacy Objective-C MVP needs something different from an enterprise stabilizing a decade of accumulated features, so we structure engagements around the stage you are actually at:

1. A dedicated Objective-C developer or small team for ongoing feature work and long-term maintenance
2. A single senior engineer to audit the architecture, untangle technical debt, and plan a gradual Swift migration
3. Short-term staff augmentation to get a stalled release, SDK integration, or performance fix out the door

Whether the priority is keeping an aging iPhone and iPad app stable, integrating a new payment or analytics SDK, or finally starting the move to Swift without a rewrite from scratch, share your requirements and Cortance will match you with Objective-C developers who have actually done it before, not just read about it.
