Ways to migrate IOS application from Swift 4 to Swift 5 efficiently

IOS devices are consistently rising in popularity these days. Due to this, Apple has released a number of unique technological updates for IOS app developers to cater to the demands of modern online business and provide users a unique user experience. One of the greatest revolutions in this direction is the release of Swift, this is the official programming language of application development for apple devices. And it is loaded with a number of unique and versatile features, which has enabled IOS app development companies in improving their development process.

Recently, to make Swift a better technology for IOS app development, Apple has released Swift 5. This new version of Swift has opened up the new gateways for achieving higher sales and profits to merchants with ease. Also, it has enabled developers to create a unique and business-specific solution for merchants. However, the applications made on Swift’s older version can not access these features. For this, migrating from Swift 4 to Swift 5 is a must. With this article, today we will take a look into how merchants can easily migrate from Swift 4 to 5 without any hassles. But before we dive into that, let us take a look at unique features of Swift 5 as discussed below:

1. With Swift 5, merchants and developers can easily enjoy ABI stability, which makes the development process more efficient for IOS developers.

2. Also, with Swift 5, Apple has introduced Result types, Raw strings, and facilities to check multiple integrations as well, which makes it easier for developers to create efficient programs using Swift.

3. Further, Swift 5 also has dynamic callable types as well. This makes it easier for applications that are written in swift to work compatibly with dynamic programming languages such as Python and Javascript.

A stepwise guide for migration from Swift 4 to Swift 5

Since Swift 5 can easily make the IOS app development more convenient and versatile, adapting to it is a must for making your IOS application scalable. Also, by using Swift 5, your application can access updated security and better performance. Below is an in-depth guide for migrating from Swift 4 to Swift 5:

Step 1: Pre-migration process

Before starting the actual procedure of migration, checking the current state of the application to get a clear idea about the state of the IOS applications and changes required in it is a must. In this process usually, the compiler related issues are solved to make the application bug free before migration. Also, in this process, you must have your project under source control for making it easier for migrator build to perform changes in it.

Step 2: Migration process

Once you have completed the setup, it is time for you to begin the migration process. This is done with the help of the Issue Navigator item. You can activate your navigation process with this. Once the migration process is done, you can easily observe the latest changes during the migration process.

Step 3: Post-migration process

Once migration is completed you might need to perform a few more changes before building the project. These changes might include minor modifications in functions, APIs and pods, etc. once these changes are performed your application is ready for use.


Migration and updates for IOS applications are a must to make them run efficiently and improve their security. Also, by migrating to Swift 5, the IOS applications become more scalable, which makes it easier for merchants to expand their online business. So, perform the migration of your IOS application to Swift 5 today and open up the gateways for higher sales.
