Native iOS app development with Swift & SwiftUI.
We build native iOS apps in Swift and SwiftUI — for founders who need App Store performance, not a cross-platform compromise.
The short answer
Swift is Apple’s native programming language for iOS, macOS, watchOS, and visionOS. Every pixel is rendered by Apple’s own Metal pipeline — no bridge, no JS thread, no third-party rendering engine. The result is 100% native performance, full access to every Apple API, and the tightest possible integration with Apple hardware.
Bolder uses Swift when the project demands the best possible iOS experience — premium consumer apps, fintech requiring Secure Enclave and Face ID, healthcare apps needing HealthKit compliance, or anything that benefits from ARKit and Apple’s spatial computing stack. Cross-platform isn’t always the right answer. Sometimes iOS-first is the product strategy.
The conversations that bring native iOS projects to Bolder.
Real scenarios that bring native Swift projects to Bolder. If one sounds familiar, we’ve built it before.
Premium iOS consumer apps
Premium iOS apps with SwiftUI, custom animations, and pixel-perfect UI that React Native and Flutter can't match on Apple hardware.
Healthcare & wellness iOS apps
HealthKit, CareKit, ResearchKit integrations with HIPAA-compliant architecture and biometric authentication.
Fintech & banking iOS apps
Fintech apps requiring Secure Enclave, Face ID, and Apple Pay — no third-party bridge touching sensitive data.
AR & spatial computing apps
AR apps with ARKit, LiDAR, and RealityKit. Only native Swift has full access to Apple’s spatial computing APIs.
Apple ecosystem multi-device apps
Apple Watch, iPad, and Apple TV apps that share logic with the iPhone app via Swift Package Manager.
On-demand & location iOS apps
High-performance iOS apps for on-demand services with real-time maps, Core Location, and push notifications.
Swift expertise that goes beyond the syntax.
We don’t just know Swift syntax. We understand Apple’s memory model, the Metal pipeline, and the App Store review patterns that sink cross-platform apps.
Native SwiftUI Rendering
SwiftUI with declarative state management via Combine. No bridge, no JS thread — every frame rendered by Apple’s own Metal pipeline.
Apple Security Stack
Keychain, Secure Enclave, Face ID, Touch ID, and App Attest — Apple’s full security stack only accessible to native Swift.
ARKit & Spatial Computing
ARKit, RealityKit, LiDAR — full access to Apple’s spatial computing stack. Flutter and React Native have no equivalent.
TestFlight & App Store Pipeline
Weekly TestFlight builds, Xcode Cloud CI, App Store submission and review handling — all in scope from day one.
Your next app shouldn't take 6 months
When native Swift is the right call.
Swift is the right call when iOS performance, Apple hardware access, or App Store quality standards are non-negotiable.
100% native. Zero bridge overhead.
SwiftUI renders every frame through Apple’s Metal pipeline. No bridge overhead, no JS thread, no cross-platform tax.
Full Apple security stack.
Face ID, Secure Enclave, Apple Pay, App Attest. Only native Swift gets full access to Apple’s security hardware.

Bolder Apps is a Miami-headquartered mobile and web app development agency, founded in 2019. They partner with startups and businesses worldwide, combining US-based leadership with a distributed engineering team.
Typically 8–20 weeks depending on project scope and complexity. Bolder Apps moves faster than most agencies — proposals are turned around in 1–2 days versus the industry norm of 1–2 weeks.
Bolder Apps serves a wide range: FinTech, Healthcare, Lifestyle, Retail, Ecommerce, Social Media, On-Demand, and Professional Services.
Headquartered at 78 SW 7th, Miami, FL 33130, USA. The engineering team is distributed globally.
At Bolder Apps, we utilize a variety of programming languages and frameworks to best suit your project’s needs. For cross-platform development, we use Flutter or Flutterflow, which allows us to efficiently support web, Android, and iOS with a single codebase—ideal for projects with tight budgets. For native applications, we employ Swift for iOS and Kotlin for Android applications.
For web applications, we combine frontend layout frameworks like Ant Design, or Material Design with React. On the backend, we typically use Laravel or Yii2 for monolithic projects, and Node.js for serverless architectures.
Additionally, we can support various technologies, including Microsoft Azure, Google Cloud, Firebase, Amazon Web Services (AWS), React Native, Docker, NGINX, Apache, and more. This diverse skill set enables us to deliver robust and scalable solutions tailored to your specific requirements.
Mobile app development typically ranges from $30K to $250K+ depending on complexity, platform, and features. Bolder Apps uses scope-based pricing — no hourly billing — so your budget is defined before development begins.
We work on fixed-scope pricing, not hourly rates. This means you know exactly what you're getting and what it costs before we write a single line of code.
Every project includes strategy, UI/UX design, development, QA testing, App Store submission, and 4 weeks of post-launch maintenance. No hidden fees.
Projects typically start from $30K. For early-stage startups, a Paid Discovery session is a cost-effective way to validate your idea and build a roadmap before committing to full development.
You connect directly with a Product Consultant — no salespeople. Within 1–2 days you receive a tailored proposal. From there: discovery → strategy → design → development → launch.
A structured engagement where we deeply analyze your product goals, user needs, and technical requirements — producing a concrete roadmap before any development begins.
Yes. We specialize in taking early-stage ideas from concept to a shippable product, fast. Many of our clients launch their first version within 10 weeks.
You work directly with a senior Product Consultant throughout the entire project — not a rotating cast of account managers or junior staff.
iOS, Android, and web. We build native apps using Swift and Kotlin, or cross-platform using Flutter — supporting all three from a single codebase when budget efficiency matters.
Yes. We integrate AI features including LLMs, recommendation engines, and automation workflows. We're an official OpenAI partner with direct access to API credits for qualifying projects.
Yes. We offer Code Audit services to review your existing architecture before recommending whether to build on top of it or start fresh.
We implement data encryption, secure coding practices, regular security audits, and follow platform-specific security guidelines for both App Store and Google Play.
