How to Move to Kotlin and Swift with InMobi SDK 10.5.8

We have released InMobi SDK 10.5.8 in Kotlin for Android and Swift for iOS. Publishers using AdMob, AppLovin MAX, DT FairBid and Unity LevelPlay as their primary mediation, or publishers using the InMobi SDK as a direct connection, can leverage the latest SDKs. We are investing more in Kotlin and Swift as the industry is moving toward programming languages that make advertising SDKs more lightweight and efficient.  

Let's look at the advantages of Kotlin and Swift:  

Advantages of Kotlin  

1. Improves productivity for developers by reducing the amount of boilerplate code needed in the app so they can do more with less code.  
2. Improves run-time performance on the app due to less memory inflation and better thread footprints.  
3. Provides better safety for Android apps as the code is 20% less likely to crash, providing a better user experience.  
4. Kotlin Coroutines (a key programming component) dramatically simplifies background task management while the app is running.  

Advantages of Swift 

1. Swift uses Automatic Reference Counting (ARC), a memory management tool, to track the app’s memory, reducing the likelihood of memory leaks and crashes.  
2. Swift is faster than Objective C because of its modern and optimized compiler.  
3. Apple has been investing more in Swift than Objective-C. As a result, new frameworks and APIs are being developed in Swift first.
