In this tutorial, you will find answers to your common questions regarding design to code in iOS app development and also learn how to generate and customize Swift code for iOS apps.  

  1. What is the Swift language used for and what are its benefits?
  2. How to convert any design to Swift code with DhiWise?
  3. How to customize Swift UI components with ease?

So without wasting further time let's get started!

1. What is the Swift language used for and what are its benefits?

Swift is a general purpose, robust, intuitive programming language developed by Apple Inc. and the open source community for building apps for iOS, Mac, Apple TV, and Apple Watch.  It is designed to give developers more freedom and flexibility than ever before. 

The programming language is easy to use, safe, Fast, and expressive. It offers a range of features such as closures, generics, type interface, and so on. Overall, it combines the features of both C and Objective-C under the same roof. 

Benefits of using Swift for iOS development:

1. Readability

Swift has a clean syntax that makes it easier to read and write. Swift code closely resembles plain English which makes it easier to learn for programmers from another background.

2. Maintenance

As compared to C and Objective-C, Swift does not have dependencies which makes it easier to maintain. Instead of maintaining two different files Swift only needs to maintain a single code file.  

 

3. Safer language

Swift syntax and language construction eliminate several types of mistakes and bring stability to your code, which means fewer crashes.  Swift enables developers to compile the code and fix the error while writing the code. 

 

4. Less boilerplate

Working with Swift language reduces your coding efforts. You need to write very less code for string manipulation and similar statements. 

 

5. Faster

The language is faster compared to python and objective-C. A complex Object sort algorithm runs 3.9 times faster than its implementation in Python.

 

6. Support for dynamic libraries

Dynamic libraries allow Swift applications to link with the code blocks and speed up the app development. These libraries are directly uploaded to the memory thus cutting down the initial app size and increasing the app performance.

2. How to convert any design to Swift code with DhiWise?

So if you are building an app for the Apple ecosystem and want to convert your UI design to Swift code just start using DhiWise the only platform for developers to build beautiful and reliable apps faster.

  6. Once you get the file in your inbox, download the file and upload it to your Figma account.
  7. Now import the design file in DhiWise.
  8. Select the screens for which you want to export code or you can generate the code for all the screens.
  9. Click the Build app to generate your final Swift code. 

DhiWise identifies the screen components and generates Swift code accordingly. If your design has UI interactions then those will be captured and converted to code by the platform. 

Moreover, developers can also use DhiWise Figma to Code plugin to convert their Figma design to Swift code. This will be helpful if you are building an app with the traditional approach but don’t want to start all from scratch. 

How to customize Swift UI components with ease?

Till now we have learned about the design to Swift code conversion but what about UI customization? DhiWise iOS App Builder lets you customize your iOS app with full flexibility.

Let's find out how.

So, once you have fetched your design screens with the screen components and the interactions if any, start customizing your app by clicking Configure.
