App Development with Swift

Outsource App Development with Swift

Swift, a fast, safe, and modern macOS, iOS, watchOS, and tvOS programming language is abundant with features like functional programming patterns, Closures unified with function pointers, Generics, etc., and delivers robust and stable codes. It can also accelerate the app development process by relieving the constraints that come with Objective C.

Flatworld Solutions is a leading Swift app development company that offers cutting-edge Swift solutions for various industry verticals, including retail, healthcare, enterprise, education, manufacturing, finance, real state, and technology. If you are looking to improve your ROI by creating a high-performing and cost-effective Swift application, then, collaborate with us.

Swift Application Development Services We Offer

Swift, whether the recent version - Swift 4 or earlier versions are an open-source language, which enables the iOS developers to share the source code, thus, allowing them to test & modify the codes and release when they are completely satisfied. A few Swift app development services that we offer are -

  1. Custom iOS Swift Development

    We provide fully customized iOS app with rich UI, cleaner, and safer codes. At FWS, we can build a completely new iOS app with Swift or leverage our 4 years of domain expertise in Swift language to modify the existing code and implement customized features according to your needs.

  2. Socket Framework

    It is difficult to receive data from the server without sending any request from the app. However, WebSocket can efficiently communicate with the server by leveraging the client-server logic. While the theory here seems simple, implementing the connection to socket requires expertise and a handful framework, i.e., Socket.IO.

    At FWS, we have assisted multiple companies to explore the benefits of Socket and make the Swift development more reliable.

  3. Objective-C Apps to Swift Conversion

    If you want to migrate an existing Objective-C app to Swift, our swift application development covers this aspect. We can help you migrate a full app by improving its architecture, logic, and performance by inserting the relevant pieces of code.

  4. Swift Apps Testing and Porting

    When you outsource app development with Swift to us, we can assist you in writing unit test code that can evaluate the Swift performance. One of the main features of Swift that limits the change of implementation methods of Swift objects is - it does not have mocking frameworks. However, our iOS developers and testers can use Dependency Injection technique to design object, and use the protocol to design the mock object, and can test the data & the behavior of the object.

  5. Support and Maintenance

    App development with Swift requires a robust coding style. We have honed our skills in providing Swift iOS development services to several global clients. When you choose us for Swift application development, you will receive seamless support and maintenance services that will ensure useful improvements and optimization at each phase of Swift app development and in the future as well.

  6. On-demand Swift Professionals

    If you want to build a project under your guidance, you can partner up with us to hire our top Swift engineers, developers, consultants, architects, and programmers. Our Swift experts can help you with customized swift app development to deploy & debug Swift programs, store data, and interface with other web services, and bridge Swift and Objective-C.

We have excellent iOS developers & designers, who follow a validated Swift application development process. Those are -


Requirement Analysis & Conceptualization

We will start app development with Swift by defining the objective of your app, finding your goals, and determining your target audience. We will also do a feasibility analysis of your app's idea, and then, sort the gathered information to plan the next step.


Design Preparation

The process starts with building a sitemap which will include the app's main functionalities and design procedures. We will then seek your approval of the design layout and proceed further to iOS app development with Swift.



This is the phase where your idea will come to life. After designing the primary software architecture, our developers will connect the app to the server by writing the first set of codes and integrate it with the server.



We will write a set of unit codes to test the app, which will give the confidence to add other features when required.



To make sure that app meets its intended potential, our developers will launch it for the internal teams by following a streamlined deployment process.
