Apple Application Development
Published on · Updated · 5 min
Have an Apple app project? I design and develop it with you, from A to Z:
New application — from idea to structure, development, and publishing
Complete rewrite — rebuild an existing app with a modern stack
Feature additions — integrate new capabilities into your product
Multi-platform expansion — port an iOS app to macOS, watchOS or visionOS
Team reinforcement — join an existing team as a Swift/iOS expert
“This service involves development. I code, I deliver, I ship to production.”
Platforms & Use Cases
iOS / iPadOS
The main platform. Native iPhone and iPad applications.
Example projects:
B2C consumer app (e-commerce, media, lifestyle)
B2B business app (mobile CRM, field tool, dashboard)
Companion app for existing web service
iOS 17+ Widgets and Live Activities
Typical stack: SwiftUI + UIKit (as needed), Swift 6, SwiftData or Core Data, async/await
macOS
Native desktop applications, optimized for Mac.
Example projects:
Utility app (menu bar, productivity)
Mac version of an iOS app (Catalyst or native)
Pro app with rich interface (editor, dashboard)
Typical stack: SwiftUI + AppKit, multi-window, sandboxing, notarization
watchOS
Apple Watch applications, standalone or companion.
Example projects:
Health/fitness extension with HealthKit
Watch complications and widgets
Standalone app with connectivity
Typical stack: SwiftUI (required since watchOS 7), HealthKit, WatchConnectivity
tvOS
Apple TV applications for the living room.
Example projects:
Media/streaming app
Casual games with controller or remote
Enterprise dashboard on big screen
Typical stack: SwiftUI + UIKit, focus engine, TVMLKit (if needed)
visionOS
Applications for Apple Vision Pro — mixed reality.
Example projects:
Immersive 3D experience
iPad app adapted for Vision Pro
Spatial workspace
Typical stack: SwiftUI + RealityKit, ARKit, Spatial frameworks

How Does It Work?
1. Scoping (1-2 weeks)
We define the scope together:
Product goals and constraints
Priority features (MVP)
Technical stack and architecture
Timeline and milestones
Deliverable: Scoping document + estimate
2. Development (iterative)
2-week sprints with regular deliveries:
Feature development
Intermediate reviews
TestFlight builds for validation
Continuous adjustments
Deliverable: Working app at each sprint
3. Finalization & Publishing
Launch preparation:
UI/UX polish
Performance and stability testing
App Store preparation (metadata, screenshots)
Submission and Apple review follow-up
Deliverable: App published on the App Store
4. Post-Launch Support (optional)
Post-publication support:
Crash and analytics monitoring
Priority bug fixes
Minor evolutions
Handover to your team if needed
My Added Value
What makes the difference when you work with me:
Production-ready code — no throwaway prototype, maintainable code
Modern stack — Swift 6, SwiftUI, async/await, no technical debt
Long-term vision — architecture designed to evolve
Full transparency — repo access, code reviews, documentation
Autonomy — I manage the project, you validate milestones
Adaptability — comfortable working solo or integrated into an existing team
“I build apps as if they were my own — with the same level of standards.”
Collaboration Models
| Format | Duration | Ideal for |
|---|---|---|
Fixed-price project | 2-6 months | MVP, complete app with defined scope |
Staff augmentation | 1+ months | Existing team integration, evolving project |
One-off sprint | 2-4 weeks | Specific feature, POC |
Engagement Contexts
I work with:
Large enterprises — structured teams, established processes, enterprise requirements
Startups — agility, MVP, fast iterations, pragmatism
Organizations — public sector, non-profits, specific needs
Work Arrangements
| Mode | Details |
|---|---|
Full remote | Default mode, collaborative tools in place |
Hybrid | Occasional on-site as needed (workshops, kickoff, reviews) |
On-site | Possible depending on location, duration and conditions |
“Work arrangements (remote/on-site) and rates are adjusted based on location, mission duration and project context.”
What falls outside this scope
- Not consulting only → see Technical Coaching
- Not an audit without follow-up → see Swift Architecture
- Not one-off optimization → see Performance
Here, we build together. You leave with a working application.
Frequently Asked Questions
"Do you work solo or with a team?"
Both. I can lead a project autonomously or integrate into your existing team as a Swift/iOS expert. I'm experienced with both enterprise environments and small startup teams.
"Do you also do design?"
I can integrate existing Figma mockups or work with your designer. For design from scratch, I recommend bringing in a dedicated UI/UX designer. However, I can help you set up a Design System.
"What happens after delivery?"
Several options: ongoing maintenance, documented handover to your team, or occasional support. We define this together.
"What's your daily rate?"
It depends on the format, duration and arrangements. We discuss it during the first call — it's free and no-commitment.
