What factors affect the cost of iOS application development?

The cost of developing an iOS application can vary significantly based on several factors, each of which is crucial in determining the overall project budget. 

Here are the key factors that influence the cost of iOS application development:

Factors that contributes directly:

  • App complexity – The complexity of your application is a major cost driver. Simple apps with basic features will cost less, while complex apps with advanced functionalities, multiple user roles, and intricate integrations will be more expensive.
  • Design and user experience – The quality of your app’s user interface and user experience design can impact costs. Custom, visually appealing designs typically require more resources and budget.
  • Features and functionality – The number and complexity of features you want in your app directly affect the cost. Features like geolocation, push notifications, and in-app purchases add to the development effort.
  • Backend development – The backend of your app, including databases, servers, and APIs, can be a significant cost factor. Building and maintaining a robust backend can incur ongoing expenses.

Below is a table that outlines key aspects for iOS backend development, along with illustrative examples of platforms, services, and tools in each category.

AspectsExamples (Platforms/Services/Tools)
Server HostingAWS, Google Cloud Platform, Microsoft Azure, Heroku, DigitalOcean etc.
DatabaseFirebase Realtime Database, Firebase Cloud Firestore, MySQL, PostgreSQL, MongoDB etc
Authentication & AuthorisationFirebase Authentication, Auth0, AWS Cognito, Keycloak
API IntegrationRESTful APIs, GraphQL, gRPC, Third-party APIs (e.g., Google Maps, Twitter), Custom APIs
File Storage & CDNAmazon S3 (Simple Storage Service), Google Cloud Storage, Azure Blob Storage, Firebase Cloud Storage, Cloudinary
Real-time CommunicationWebSocket, Firebase Realtime Database (for chat apps), MQTT (Message Queuing Telemetry Transport), Pusher, Socket.io
Logging and MonitoringGoogle Cloud Monitoring, Amazon CloudWatch, New Relic, Datadog, 
Scalability & Load BalancingAWS Elastic Load Balancer, Google Cloud Load Balancing, NGINX Load Balancer, Kubernetes (for container orchestration)
SecurityJWT (JSON Web Tokens), OAuth 2.0, SSL/TLS, Web Application Firewalls (WAFs), Security Headers (e.g., Content Security Policy)
Data Backup & RecoveryRegular Data Backups, Version Control (e.g., Git), Automated Disaster Recovery Plans, Data Replication

Please note that these factors serve as key aspects, and the examples provided represent various aspects of backend development in an iOS application. Depending on the unique requirements of your project, you have the flexibility to select different platforms, services, and tools that align with your specific backend development needs.

  • Testing and quality assurance – As you might imagine, it would be foolish to launch an application without any testing and QA. When it starts to increase your costs is when you require robust documentation and testing beyond the normal (like security testing and performance testing).
  • Project management – Every application needs somebody to keep it on track and hit the milestones along the way. This can be a part of someone’s role, but if it requires (due to the size of the team or complexity of the work) someone to be in a dedicated project manager role it will increase the overall cost of development.
  • Geographical location – The location of your development team can significantly impact costs. Developers in regions with higher living costs tend to charge more than those in lower-cost areas.

Additional contributing factors:

  • Third-party integrations – If your app requires integrations with third-party services or APIs, it can impact costs. These integrations may involve additional development and licensing fees.
  • Legal and compliance requirements – Apps must comply with various legal and regulatory standards. Ensuring legal compliance can require additional resources and budget.
  • Security measures – Implementing robust security features and regular security audits can add to development costs but are essential for protecting user data.
  • Customisation vs. templates – Custom-developed components tend to be more expensive than using pre-built templates or components. Deciding between customisation and templates can impact costs.

How does iOS contribute to reducing app development costs?

  • Swift programming language – iOS development primarily uses Swift, a language known for its simplicity and readability. Swift’s concise syntax can lead to faster development, reducing coding time and costs.
  • Reusability – iOS applications are designed to work on various Apple devices, such as iPhones, iPads, and Macs. This reusability of code and design elements across different Apple products can lower development expenses.
  • Integrated development environment (IDE) – Apple’s Xcode, the official iOS development IDE, offers a wide range of tools and features that streamline the development process. It includes code completion, debugging tools, and Interface Builder for UI design, contributing to development efficiency.
  • Quality assurance – iOS benefits from rigorous app review processes before publication on the App Store. This helps ensure a higher standard of quality and may reduce post-launch debugging and support costs.
  • User interface components – iOS provides a collection of pre-designed user interface components, known as UIKit, which simplifies the app design process. Also, you can use SwiftUI for designing your application’s interface, since it is the latest declarative UI framework introduced by mobile application. This reduces design costs and accelerates development. Apple’s strict UX guidelines help create user-friendly and intuitive applications. By adhering to these guidelines, developers can avoid costly redesigns and ensure user satisfaction from the start.
  • Security and privacy – iOS places a strong emphasis on user data security and privacy, which can reduce the likelihood of costly data breaches and legal issues associated with user data mishandling.
  • Community and resources – The iOS development community is vast and active, providing access to resources, open-source libraries, and forums. Developers can leverage these resources to solve problems and save development time.

So how much does developing an iOS application actually cost?

It depends on whether you choose to harness in-house expertise or explore the offshore application development route, along with a myriad of factors that intricately weave together to define the overall development cost.

When building an iOS app with an in-house team, you’ll need to budget for salaries, benefits, office space, and equipment for your developers and any other necessary team members, such as designers and testers. The cost of hiring and retaining experienced iOS developers can be substantial, especially in regions with high demand for tech talent, such as Silicon Valley.

On the other hand, outsourcing to an offshore development team offers potential cost savings. Offshore developers often provide competitive rates, but the quality of work and communication may vary. Consider factors like the size of the offshore team, the project’s complexity, and the chosen outsourcing location. While cost savings can be significant, you must carefully evaluate the credentials and track record of the outsourcing firm to ensure the success of your project.

The cost of developing an iOS application in-house

The cost of hiring in-house iOS application developers can vary significantly based on factors such as location, experience, and skill set. In regions with a high demand for tech talent, such as Silicon Valley, salaries and benefits tend to be higher. In-house developers require office space, equipment, and other overhead expenses, all of which contribute to the overall cost. Businesses must consider their budget and project requirements when determining the cost of in-house development.

Consider the following essential factors when hiring an iOS application developer:

  • iOS proficiency – Look for developers with a deep understanding of iOS development, including knowledge of Swift and the iOS SDK.
  • Mobile development experience – Prior experience in iOS mobile app development, is valuable for understanding mobile-specific challenges and user expectations.
  • Programming proficiency – Assess their coding skills, focusing on their ability to write clean, efficient, and maintainable code in the iOS environment.
  • UI/UX design skills – A developer who understands user interface (UI) and user experience (UX) design principles can contribute to creating visually appealing and user-friendly apps.
  • Experience with state management – Developers should have experience managing the app’s state and data flow efficiently, which is crucial for app responsiveness and stability.
  • Problem-solving abilities – Seek developers who can think critically and solve complex issues, a common requirement in iOS application development.
  • Collaboration skills – Effective communication and teamwork are vital, as iOS developers often work with designers, testers, and other team members to create successful applications.

The cost of developing an iOS application through outsourcing

Conversely, the outsourcing of iOS development entails enlisting the services of a third-party development agency or freelance professionals to conceive and maintain your iOS application. This strategy affords you the adaptability to scale your development team according to your project’s needs, often minimising initial expenses since you only incur costs for services rendered.

Outsourcing can prove especially advantageous for brief undertakings since you don’t have to take the pressure of managing the project all by your own as you have a team to look after it, MVP (Minimum Viable Product) development, or when you require specialised expertise. Moreover, it provides the opportunity to tap into a global talent reservoir, potentially granting you access to a more extensive array of skill sets.

However, outsourcing may introduce challenges concerning communication, disparities in time zones, as well as apprehensions related to data security and quality control. For an in-depth exploration of how to proficiently navigate the selection process of an application development team, you can refer to the article on how to hire an application development team.
