Convert Objective C App to Swift

April 20, 2019

Migrating the files to Swift gives a chance to return to a current Objective C code and enhance its design, rationale, and execution. This happens supplanting bits of it in with Swift. If you wish to convert the entire project applications like Swiftify, improve the way towards decoding the source code from Objective C to Swift. The ability to exchange property syntax makes it possible to integrate the changed over code once again into the Objective C project with no issue. This implies you can utilize Swiftify to know Swift’s appropriate usefulness at any point in time. Later you can incorporate these into your Objective-C files without altering the source code to Swift.

Swift has many advantages over Objective C. You can milk the advantages of mobile applications by converting the code.


Even though Swift evolved much later compared to Objective C it has outshined the later to turn out to be the favorite of iOS developers. Why so?

Swift’s syntax is very simple and user-friendly. It is easy considering aspects from coding languages like Python, Ruby, and Rust. Swift’s coding structure and language constructions avoid various types of errors probable in Objective-C. It comes with bundles of pros when compared to Objective-C suitable for present-day needs. Hence, instead of upgrading Objective-C Apple decided to create Swift from scratch. Swift eventually has less coding struggles while coding repetitive arguments or performing string operation. It has imbibed several modules from Objective-C while also bringing in a set of new landscapes, letting developers write secure and more consistent code.

Swift vs Objective c trends for 2017 and beyond

Here are some pros of Swift over Objective -c:

  • Swift is an open source language
  • Minimal coding efforts
  • Adaptable to upgrades and changes
  • Requires fewer maintenance efforts
  • Eases the development process
  • Requires very less memory space
  • Development is less costly
  • Has a large community of developers
  • Can develop intricate apps with ease
  • Supports cloud-based app development

Probably, the latest aspects of Swift are, enhanced security features, advanced space management, several return values, and a group of well-designed standards. Owing to these benefits a developer wishes to switch from objective c app to swift.

Steps to convert Objective C App to Swift

Step 1:

Check for the latest version:

It is to be remembered during the migration of objective c to swift that the most recent version of the Objective C code has to be in effect. Using a latest Objective c converter, Xcode lets you add the appropriate enum commands, compile the project and fix, convert the id to instance type wherever it is potential. The most recent @property syntax is also updated here.

The iOS app developers must be cautious here as the converter tools will not demonstrate the rules of the code. On the other hand, it will assist you in identifying and engaging the procedure of possible updates which saves thousands of work hours. As a result, it is worthwhile to verify the whole thing yourself and then go for any modifications.

Step 2:

Move One Class at a Time: You must be aware that you cannot change all your codes at an instance, However, you can move class by class.

Step 3:

Convert a couple of Objective-C files to Swift. You can do this using the Finder extension embedded with Swiftify for Xcode.

Step 4:

Create an objective c bridging header. The bridging header lets you use both Swift and Objective-C in the same project as both the codes can function well in the same app in swift.

Step 5:

Perform Nil Checks: You will obtain a null value in return when a call is directed towards the nil object in Objective-C language. If you wish to escape it, you must remember to accomplish nil checks as per requirements.

Step 6:

Substitute the .h and .m files with altered .swift file types in the project.

Step 7:

Finally, compile the project and fix the switchover inaccuracies. Most of the issues are usually handled by using Xcode auto-fix recommendations; you can also count on Swiftify to identify and track the errors coming up many times in the project. Finally, build and run the entire project. You can convert the Objective C App to Swift by following these seven steps.
