What We Build

Comprehensive Native iOS Engineering

01

Swift & SwiftUI Development

Developing clean, modern native apps using Swift and SwiftUI for reactive UI, combined with UIKit for deep system integrations and backward compatibility.

02

App Store Submission & Compliance

Navigating Apple's strict review process. We ensure absolute compliance with App Store Guidelines, app privacy declarations, and secure data handling.

03

Apple Ecosystem Integration

Leveraging native device features—FaceID/TouchID, Apple Pay, CoreLocation, Push Notifications, WidgetKit, Apple Watch extensions, and SiriKit.

04

High-Performance Rendering & Metal

Building smooth, high-framerate animations and interactive 3D components using Core Animation and Apple's low-overhead Metal API.

05

Secure Local Storage & Core Data

Implementing secure offline capabilities utilizing Apple's Keychain for secrets, Core Data/SwiftData for complex relational storage, and SQLite for high-performance indexing.

06

Automated Test Coverage & CI/CD

Building automated unit and UI testing suites using XCTest, integrated into robust CI/CD pipelines (Xcode Cloud, Bitrise) for seamless deployment.

The Challenge

The Apple ecosystem demands absolute polish. Users won't settle for half-baked web wrappers.

iOS users are discerning. They expect smooth animations, instant load times, and a native look and feel that conforms to Apple's Human Interface Guidelines. Yet, many teams attempt to save money by shipping cross-platform web wrappers that feel sluggish, drain battery life, and break on new iOS releases. Worse, failing to understand Apple's strict privacy and security guidelines can result in your app being repeatedly rejected by the App Store review team. Quecko builds native iOS apps from the ground up, utilizing Swift and modern architecture patterns to deliver lightning-fast performance, rock-solid security, and an interface that feels right at home on the iPhone.

Our Edge

We Build for the Apple Ecosystem with Uncompromising Detail.

We don't just build apps; we design them to feel like Apple built them. We respect spacing, typography, and interactive touch targets to deliver premium feel.

Human Interface Guideline Experts

We don't just build apps; we design them to feel like Apple built them. We respect spacing, typography, and interactive touch targets to deliver premium feel.

Type-Safe Swift Architecture

We utilize modern Swift features—async/await, actors, and generics—to build codebases that are highly performant, thread-safe, and easy to maintain.

App Store Submission Success

We have successfully submitted dozens of applications to the App Store, maintaining an impeccable record of navigating Apple's strict review guidelines.

250+ Products Shipped

We bring a disciplined engineering approach to mobile, matching our success in complex enterprise and Web3 systems.

FAQ

Frequently Asked Questions

Native Swift gives you absolute control over performance, animations, and memory usage. It ensures zero lag, full access to new Apple features on day one, and a UX that matches Apple's guidelines perfectly. If your app requires complex graphics, heavy background processing, or premium UI polish, native Swift is the optimal choice.

Typically 24 to 48 hours, though it can take longer if Apple raises questions regarding data privacy, subscriptions, or requires clarification on specific features. We minimize this time by ensuring absolute compliance before submission.

Yes. We integrate Apple Pay natively using Apple's PassKit framework, linking it securely to your payment gateway (Stripe, Adyen) to ensure frictionless, single-touch transactions.

We use Apple's TestFlight to distribute beta builds to internal and external testers. We track crashes and performance data in real-time, ensuring all major issues are resolved before the public App Store release.
