Trango Tech’s Traditional Technology Stack for iOS App Development


Objective-C has been the conventional choice for iOS app development for years. It has a mature ecosystem with a variety of choices in libraries, tools and development resources. It’s highly stable and reliable for building robust iOS applications. It’s also ideal for business apps that are built either on legacy projects or require compatibility with existing iOS-based solutions. Most importantly, it provides deep integration opportunities with Apple’s framework. That’s why, our developers can use APIs and access system-level functionalities, hardware features and platform-specific capabilities when building feature-rich iOS applications.


Swift is the post-modern choice for iOS app development. It has the latest syntax and ready-made features that help Trango Tech’s developers build applications smartly – less time and more opportunities with ready-to-market iOS apps. Most importantly, Swift’s laser-focus on experience and privacy help with building apps that are high quality, have sustainable code and are super scalable. If you’re a business planning to use emerging technology integrations in your app like Artificial Intelligence and Machine Learning algorithms, Virtual Reality frameworks or Internet of Things for smart home automation – Swift is your way to go!

Xcode 15

Xcode is Apple’s official integrated development environment that helps our developers build and test apps faster with smart code completion. It works exceptionally well with iOS, macOS, watcOS and tvOS application development. It has a comprehensive suite of built-in tools for editing code, debugging, testing and analyzing performance. Trango Tech’s developers utilize the Interface Builder from Xcode to design user interfaces visually.

Swift Plagrounds

Swift Playgrounds is basically an interactive development environment that helps developers write, edit and develop code for Apple apps. It’s in the form of an application that runs on iPad and Mac and ideal to experiment with Swift code and APIs.  



Firebase is a cloud-hosted NoSQL database from Google. It offers real-time data synchronization and integrates well with iOS apps through the Firebase SDK. Because of its powerful synchronization capabilities, it provides real-time updates and connects through multiple clients and devices simultaneously. It is the ideal backend solution for iOS app development because of its features like authentication, cloud messaging, analytics and hosting.  


UIKit is the official framework provided by Apple to design user interfaces for iOS applications. It has a set of classes and APIs that help with building user interactions, displaying content, managing views and implementing important UI elements.

Foundation Framework

Foundation Framework is a core framework that has essential classes and functionalities for iOS app development. Most important assets of Foundation Framework include data type collections, file management assets and networking.

Cora Data

This is Apple’s framework for managing the model layer objects in iOS apps. It provides object graph management which allows developers to store, fetch and utilize data in different forms in their applications.

Trango Tech’s iOS Mobile App Development Process

We have a structured, agile development process that helps our developers and project managers efficiently plan, develop and deliver high-quality iOS applications to our clients. Take an insider look at our iOS development process.


The main objective of our discovery stage is to understand our clients’ requirements, listen to their product vision and the ways how iOS app development can help their businesses. For this, we conduct FREE product validation sessions with the client and create market research reports including a thorough competitor analysis. Main deliverables of this stage include product development roadmap, monetization strategy for the iOS application, list of features and technology stack.


We follow a design-led approach to represent the user journey and feature map of the app. The process starts with initial sketches of the app features – these are wireframes with minimal drawing to understand primary navigation. Then we build brand assets based on style guide, app screen mockups for each navigation point and feature and turn them into a high-fidelity, clickable, interactive prototype. We use Adobe XD and Figma to create these prototypes and they are accessible by our client’s teams too.


The pre-development step requires us to do strong sprint planning in which we divide backend and frontend development KPIs, API integration KPIs and database setup KPIs. Each of our development sprints is 10 business days with a sprint preview and sprint review session before and after sprint completion. Our project managers keep the project on track while following this sequence: we code the face of the app first. This is the prototype translated into frontend. Then we code the backend for security and data handling. Then we integrate APIs to help users access external services and then we set up databases.


The development process is followed by the testing and quality assurance phase where our main objective is to put together an iOS application that is error-free and has the most excellent user experience possible. We start with identifying and solving bugs, then check the usability issues to make sure the app is stable, performant and compatible across devices. We perform five main tests that include: functionality tests, integration tests, device tests, unit tests and security tests.


After the testing step, the app is ready to deploy, publish on the App Store and ready to be downloaded and used by the target audience. We prepare the App Store Optimization documents, create keyword-based descriptions and take screenshots. Then we create App Store Connect account on behalf of our clients, pay the developer fee and submit the app for approval – which may take an average of 2 weeks.


All of our clients qualify for a standard FREE post-launch maintenance period specified in their contracts. After that, we sign new contracts for on-going app support and maintenance services, feature updates and development scaling. During this maintenance period, we provide technical support to app users, monitor app performance, document app crashes, check error logs and send out new updates to improve user experience.

Working With The Best in Business

Our clients, employees and partners make us who we are - we work with them to make the global business ecosystem more welcoming, adaptable and lucrative for everyone!

    iOS app development is the process of building mobile application for Apple’s iOS platform and primarily for iPhones, iPads and tvOS and watchOS. Trango Tech uses a dedicated Apple technology stack for developing iOS apps, which utilizes the Swift, Objective-C, Xcode 15, Core Data, Firebase and a set of integrated development environments.
    As a business, Android vs iOS is a subjective decision where you have to consider the target audience and their demographics, your app development idea and its device-level suitability, market preferences, launching timelines, budgets and business objectives. While it is a strategic choice, you can validate your idea and iOS app development by considering that it is the most financially rewarding app ecosystem because iOS reported highest app revenue from subscriptions and in-app purchases. Also, it is the second leading operating system in terms of user base.
    Basic iOS applications with 2 to 4 features typically take three months with full-cycle coverage from design to testing. Intermediate-level, multi-featured app with 3 to 6 features may take anywhere between 4 months to 6 months in design, development, testing, and launch.
    Advanced applications with more than 8 features can take anywhere between 6 months and 9 months. These timelines significantly vary because of design requirements, product vision and goals, development approach and technology stack and approval speeds from client’s side.
    At Trango Tech, the cost of iOS app development starts from $5000 and can go up to $75000 for advanced applications leveraging artificial intelligence, virtual reality frameworks and IoT-embedded smart development. We also provide subscription model where our clients don’t have to pay upfront but a subscription amount every month. While we try to keep our app development tiers on-point and in-budget for everyone with brilliant ideas, we also consider custom quotes that are tailor-made for specific apps.
