Objective-C projects rarely start with a blank slate. Buyers are usually looking for a team that can understand an established Apple codebase, fix stability problems, add features, or plan a controlled move to Swift. The companies below combine documented Objective-C capability with a US headquarters, office, representation, or active delivery presence.
Gilzor develops and supports native iOS products as part of its broader mobile engineering practice. Its published stack includes Objective-C, Swift, SwiftUI, Xcode, Kotlin, and React Native, while its services cover product discovery, UX/UI, backend integration, QA, App Store publishing, and post-release maintenance. This breadth is useful when an older Objective-C application has problems beyond the language itself, such as weak architecture, crashes, integration issues, or an unclear product roadmap. Gilzor works with US clients and lists representation in the United States alongside its European operations.
ScienceSoft has a long-running iOS practice that explicitly covers Objective-C and Swift. Its mobile team develops native applications and works with Apple capabilities such as Apple Pay, iCloud, Core Bluetooth, NFC, and Siri. The company also publishes modernization work involving transitions from Objective-C to Swift, making it relevant to organizations that need to reduce legacy risk without treating a rewrite as the automatic answer. ScienceSoft is headquartered in the United States and works across regulated and data-sensitive fields, including healthcare, finance, insurance, and retail.
SCAND maintains a dedicated Objective-C service and uses the language for custom Apple applications across iPhone, iPad, Apple Watch, and Mac. Its iOS offering includes new development, support for existing code, third-party integrations, migration, and modernization of older Objective-C or Swift applications. That makes the company a practical candidate for businesses managing a mature product rather than commissioning a simple consumer app. SCAND has a New York office and also operates a development presence in Europe.
BairesDev provides iOS engineers through nearshore delivery teams aligned with US time zones. Its iOS service names Objective-C, Swift, Xcode, UIKit, and Core Data, while its Swift practice also covers phased migration of mixed Objective-C and Swift codebases. The model is suited to companies that already own the product roadmap and need experienced engineers to join an internal workflow. BairesDev describes itself as a US-based company supported by Latin American development teams, offering a useful balance between regional coordination and distributed delivery capacity.
Imaginovation offers a dedicated Objective-C development service for custom iOS applications. Its wider mobile practice includes native iOS and Android development, enterprise mobile software, system integration, legacy modernization, and ongoing support. This is a sensible fit for a company that wants one vendor to examine an aging application, improve its architecture, and connect it to current ERP, CRM, or backend systems. Imaginovation is headquartered in Raleigh, North Carolina, and works with funded startups as well as established businesses.
A-listware provides mobile development and dedicated engineering teams for businesses that need external capacity or a managed delivery partner. Its mobile technology list explicitly includes Objective-C alongside Swift, Kotlin, Xamarin, Cordova, React Native, and Flutter. The company can therefore support native Apple code while also covering backend work, UX/UI, QA, DevOps, and software maintenance. Its published portfolio spans ecommerce, telemedicine, mobile banking, field service, and remote-control applications. A-listware operates in the US market and offers team augmentation as well as full-cycle development.
Simform delivers native iOS and Android applications through distributed engineering teams. Its US app development pages identify Objective-C as part of the iOS skill set, together with Swift, Xcode, and the iOS SDK. The company also handles product design, cloud engineering, API development, DevOps, and ongoing application maintenance, which can reduce handoffs on products with substantial backend dependencies. Simform is headquartered in Florida and publishes additional US locations, including San Francisco, Los Angeles, and Dallas.
Intersog has a specific Objective-C development service for iOS and macOS products. The company supports custom development, staff augmentation, dedicated teams, and full-cycle delivery, with engineers available across North America and Latin America. Its published work also includes an Objective-C application built for a financial services organization, giving buyers a more concrete signal than a language appearing only in a general technology list. Intersog is headquartered in Chicago and is well positioned for companies seeking regional coordination with distributed engineering talent.
Appinventiv develops custom mobile products for enterprises and growth-stage companies. Its iOS service explicitly lists Objective-C and Swift, while the wider mobile offer covers consulting, architecture, UI/UX, backend engineering, legacy modernization, testing, deployment, and long-term maintenance. That service range is relevant when an Objective-C application must be updated without separating code work from security, product design, or platform integration. Appinventiv maintains a United States office in Manhattan and works across sectors such as fintech, healthcare, ecommerce, and consumer services.
Elinext maintains a dedicated Objective-C development offering rather than treating the language as a historical footnote. Its service covers iOS application development, existing-product work, integration, maintenance, and modernization, supported by broader mobile, QA, cloud, and custom software teams. The company also publishes Objective-C work involving connected devices and mobile applications, which may be relevant to products that communicate over Bluetooth or depend on embedded systems. Elinext has a US office in Syosset, New York, alongside delivery locations in Europe and Asia.
Itexus includes Objective-C in its native mobile application stack alongside Swift, Kotlin, and Java. The company is particularly focused on fintech software, with services spanning mobile banking, payments, lending, investment platforms, insurance systems, and AI-enabled financial tools. For a mature financial iOS product, that domain concentration can matter as much as language proficiency because development may involve authentication, payment integrations, sensitive data, and compliance requirements. Itexus lists a US office in Dover, Delaware, and provides full-cycle development from discovery through maintenance.
Chetu is a US-based software development provider with a large on-demand engineering model. The company lists Objective-C among its developer capabilities and uses the language within iOS mobile and game development, alongside Swift and other native and cross-platform technologies. Its broader practice covers custom application development, integrations, platform modernization, support, and industry-specific systems. Chetu can suit established organizations that need extra development capacity across several connected systems, though buyers should define the exact Objective-C seniority and codebase responsibilities during technical screening.
Siblings Software offers Objective-C staff augmentation for established iOS and macOS codebases. The service is framed around stabilization, continued feature development, and gradual modernization, with access to Swift and SwiftUI engineers when a product is ready for mixed-language work or phased migration. Companies can use individual staff augmentation, dedicated teams, or project outsourcing depending on how much delivery ownership they want to retain. Siblings Software operates from Miami and uses nearshore Latin American teams to provide working-hour overlap for US clients.
Webskitters includes Objective-C within its native mobile development practice and also works with Swift, Kotlin, Java, Flutter, and React Native. Its service mix covers application planning, UI/UX, native and hybrid development, backend work, testing, and support. This makes it a possible fit for companies that need to maintain an iOS codebase while also supporting Android or web components. Webskitters lists US offices in California, Florida, and Delaware, giving American buyers several domestic contact points for a delivery organization with international engineering resources.
ManekTech provides mobile application development from its US office in San Antonio and additional international delivery locations. Its iOS materials reference Objective-C and Swift, while the wider mobile practice covers native development, cross-platform applications, UI/UX, migration, maintenance, and developer hiring. The company is most relevant to buyers who need a flexible outsourced team rather than a narrow boutique focused only on one Apple language. Its ability to cover Android and cross-platform code can also help when the iOS product is one part of a larger mobile portfolio.
Objective-C may no longer be Apple’s headline language, but plenty of valuable apps still depend on it. Replacing a mature codebase just because Swift is newer can create more trouble than it solves. The smarter route is often to stabilize what already works, clean up technical debt, and migrate only where there is a clear practical benefit. The companies on this list approach challenges from different angles, from focused legacy maintenance to full product redevelopment.
Before choosing a team, look beyond a general claim of “iOS expertise.” Ask who will inspect the existing architecture, how they test changes against older modules, and whether they have a sensible plan for Objective-C and Swift interoperability. A good partner should be comfortable preserving reliable code as well as replacing the parts that have genuinely become a liability. That balance matters far more than chasing the newest stack for its own sake.
