iOS App Development Services in Swift for iPhone and iPad

Swift, Apple's primary programming language for iOS development, is the correct choice for any new project. It receives active investment from Apple, produces safer code through its type system, and is required for SwiftUI, Apple's declarative UI framework. Netofficials uses Objective-C, Apple's earlier programming language, only when a project must call into an existing legacy codebase that has not been migrated. For older Objective-C apps, we can plan a phased Swift app development migration alongside active feature work.

App Review, Apple's process for evaluating apps before they appear on the App Store, is controlled entirely by Apple, and its duration varies based on submission volume, app category, and the completeness of the materials provided. Common rejection causes include missing privacy manifest files, incomplete demo credentials for reviewers, in-app purchase flows that bypass Apple's payment system, and violations of Apple Human Interface Guidelines. Netofficials prepares all App Store Connect metadata, screenshots, and reviewer notes, and manages rejection responses as a standard part of every submission engagement.

Yes. A Universal app, an iOS application that runs natively on both iPhone and iPad, is built from a single Swift codebase in Xcode, Apple's integrated development environment. SwiftUI's adaptive layout system handles many screen-size differences automatically, but a distinct tablet workflow, split-view navigation, or iPad-specific input handling requires dedicated design and development effort. If your iPad requirements are substantial, our iPad app development service covers that scope in detail.

Yes. Netofficials works on live iOS apps, including adding features to an existing Swift codebase, migrating an Objective-C app to Swift, and full rebuilds where the current code is no longer maintainable. Every engagement of this type begins with a structured audit of the Xcode project: we review App Store Connect account status, identify deprecated APIs, and flag outdated dependencies. The audit output defines the scope and prevents cost surprises. See our legacy modernisation service for projects where the rebuild scope is large.

Cost and timeline are determined by the number of screens and user roles, the complexity of backend and third-party API integrations, and which Apple frameworks the app requires. Projects using ARKit, Apple's framework for augmented-reality experiences, Core ML, Apple's framework for on-device machine learning, or CloudKit, Apple's framework for syncing data across Apple devices, carry more engineering effort than apps using standard UIKit or SwiftUI views. Compliance requirements, Apple Watch companion features, and offline storage via Core Data also affect scope. Review our engagement models to understand how Netofficials structures and prices projects.

You retain full ownership of the source code, the Xcode project, and the App Store Connect listing throughout and after the engagement. All code is held in a version-control repository that you own or have unrestricted access to. App Store Connect accounts are registered under your Apple Developer Program membership. Netofficials operates as a collaborator on your account, not as the account holder, so you can release updates, manage pricing, and respond to reviews independently once the engagement ends.

Netofficials treats App Store rejection responses as part of the standard submission scope, not a separate billable event. When Apple's App Review returns a rejection, we analyse the specific guideline cited, update the build or metadata accordingly, and resubmit through App Store Connect. Where a rejection involves a policy interpretation that requires written clarification to Apple, we draft and submit that response. Submissions are prepared against Apple Human Interface Guidelines and App Review Guidelines before the first submission to reduce the likelihood of rejection.

Netofficials is an India-based software development company, so overlap with US, UK, and Australian business hours requires deliberate scheduling. Each project uses a shared project management tool with asynchronous updates so buyers can review progress without waiting for a live call. Sprint reviews, planning sessions, and milestone sign-offs are scheduled at times that work for both sides. Buyers receive access to the version-control repository and a staging build via TestFlight, Apple's platform for distributing beta builds, so progress is visible at any hour.
