iOS開発サービス

MicrocosmWorks provides native iOS app development using Swift and SwiftUI, UIKit-based legacy app modernization, watchOS and tvOS companion app development, App Clip creation, and iOS app maintenance. We build apps optimized for the latest iPhone, iPad, and Apple Silicon hardware.

We use SwiftUI for new projects targeting iOS 16+ to take advantage of its declarative syntax, native animations, and faster development cycles. For apps requiring backward compatibility or complex custom UI, we use UIKit or a hybrid SwiftUI-UIKit approach with hosting controllers.

Custom iOS app development with MicrocosmWorks starts at $8,000 for a basic MVP and ranges up to $60,000+ for feature-rich enterprise applications, with developer rates between $10 and $50 per hour. Pricing depends on features, backend complexity, third-party integrations, and design requirements.

Yes, our iOS developers have deep experience integrating Apple frameworks including HealthKit for health data, ARKit and RealityKit for augmented reality, Core ML for on-device machine learning, SiriKit for voice commands, and StoreKit 2 for in-app purchases and subscriptions.

We use Xcode Instruments to profile memory, CPU, and energy usage, ensuring smooth 60fps performance and minimal battery drain. For App Store optimization, we handle keyword research, localized metadata, A/B tested screenshots, and strategic review prompting to improve discoverability and conversion rates.
