Objective-C development services

Agilie’s Objective-C services empower companies to sustain and modernize legacy iOS applications developed before Swift became the key standard.

When Objective-C is still relevant

Objective-C remains important for established iOS apps that demand proven stability, low-level system access, and a phased approach to modernization.

Support for existing iOS apps

Objective-C plays an essential role in keeping live production apps, particularly when complete rewrites can lead to unnecessary risks and operational disruption.

C/C++ libraries support

Objective-C works seamlessly with C and C++ libraries, which makes it a strong choice for apps that depend on low-level code or need high-performance processing.

Enterprise legacy codebase

A lot of enterprise iOS systems are still built on massive Objective-C codebases that need ongoing maintenance, stability improvements, and long-term care.

Phased Swift migration

Objective-C enables a modular migration path to Swift, allowing architectural upgrades at a sustainable speed while preserving production stability and consistency.

Our Objective-C expertise

Since 2013, Agilie has focused on Objective-C, developing expertise in maintaining, scaling, and modernizing live apps.

Home Safety Solution

Agilie used Objective-C to build a connection between the app and home sensors. This was critical to make sure that life-saving data, like smoke or motion alerts, always got through immediately. It also covered the background tasks, including geolocation and emergency alerts, all central to the IoT safety platform.

The Wholesale B2B Marketplace

The first iOS Wholesale B2B Marketplace version was developed with Objective-C. This covered the production codebase, which provided the main infrastructure for the marketplace supplier and retailer ecosystem. As the project evolved, Agilie implemented a phased migration strategy to transition the app to Swift for ecosystem support.

Agilie’s Objective-C development services

Agilie delivers dedicated Objective-C development and modernization services, ensuring production stability while defining a clear path toward strategic migration.

Legacy application support

We keep and stabilize existing Objective-C apps, resolving defects, ensuring compatibility with the latest iOS releases, and extending project lifespan.

Refactoring and optimization

Agilie refactors and optimizes legacy Objective-C code to improve work, readability, and reliability, without changing business-critical functionality.

Gradual migration to Swift

We implement a phased migration strategy, introducing Swift modules incrementally while saving production stability and cutting operational risk.

Feature integration

Agilie implements new features within existing Objective-C systems, ensuring alignment with modern iOS standards and long-term architectural direction.

Code and technical debt audit

We conduct comprehensive code and technical debt audits to identify structural vulnerabilities and architectural risks that may deter development.

The web and mobile technologies we use

We use Firebase as a high-performance background foundation, integrating it with a specialized tech stack to provide a full-cycle product delivery.

Recommendations for modernization

Expert modernization roadmaps help organizations to mitigate risk and cut costs while transitioning legacy infrastructure without stalling business operations.

Migration strategies

Instead of total rewrites, the Agilie team develops custom migration roadmaps aligned with your codebase volume, acceptable risk level, and business goals to implement a low-risk migration.

Dual-stack operation

A hybrid architecture enables Objective-C and Swift to coexist within the same codebase, allowing a secure modernization path while deploying new capabilities without interruptions.

Structured execution

We split modernization into clear stages with set timelines and clear goals, accompanied by measurable milestones, to ensure steady technical growth without interrupting ongoing tech operations.
