Swift is Apple's programming language for iOS development. SwiftUI is a modern UI framework built with Swift that uses a declarative syntax for defining user interfaces. SwiftUI is Apple's direction for new development and offers faster UI iteration, live previews in Xcode, and seamless integration with new iOS features. UIKit is the older, imperative UI framework still widely used and fully supported. We use SwiftUI for new projects and UIKit where mature library support or backward compatibility requires it.

Apple's App Store review is thorough and can be demanding. Apple checks apps for policy compliance, quality standards, accurate metadata, privacy requirements, and functional stability. Common rejection reasons include crashes, guideline violations, privacy label inaccuracies, and misleading descriptions. We design and build apps with App Store requirements in mind throughout development and manage the submission process, addressing reviewer feedback promptly to achieve approval efficiently.

We typically support iOS versions covering the two most recent major releases, which covers the vast majority of active iOS devices. Device support covers current and recent iPhone and iPad models. We advise on the right minimum OS version for your app based on the features required and your target audience demographics. We test on physical devices covering the most significant screen sizes in the iOS device range.

Yes. We implement Apple Pay for in-app purchases and transactions — setting up merchant identifiers, configuring payment request objects, handling transaction authorisation, and integrating with your payment processor backend. Apple Pay delivers a significantly better checkout experience than entering card details manually and typically improves conversion rates for e-commerce and ticketing apps.

We conduct multiple testing phases — functional testing on physical devices, regression testing across UI changes, performance profiling using Instruments, memory leak detection, accessibility testing (VoiceOver), and compatibility testing across supported iOS versions. We use TestFlight for beta distribution to real users before App Store submission. Thorough testing is essential to passing App Store review and maintaining positive user ratings.

Apple's review process typically takes one to three business days for standard reviews. Apps in sensitive categories (finance, health, kids) sometimes receive more detailed review. If an app is rejected, we receive feedback from Apple's review team and address the issues before resubmission. We manage this process for all our clients, responding to reviewer feedback and resubmitting promptly.

Yes. We build universal iOS apps that run on both iPhone and iPad with appropriate adaptive layouts — either a unified interface that adapts to screen size or distinct optimised layouts for each form factor. Building universally from the start is more cost-effective than building separate apps and gives your app broader reach across Apple devices.
