Load Java library from "Swift"

Recently, I started developing apps and tried to proceed with hybrid apps, but due to performance problems, I switched to native app development.

In order to increase production efficiency by emphasizing similarities in terms of grammar of the language, "Kotlin", a language similar to "Swift" of IOS, was adopted in Android (to facilitate IOS development after Android development).

In order to provide uniformity of core functions (Kernel) other than UI even if the development platform is changed Create a Java library with Kotlin.

So that I don't have to create new core features that were produced on Android Bring up the Java library that Swift made

I'm thinking about ways to increase the production efficiency.

Will the way I'm thinking now work to increase production efficiency?

While developing Android and IOS native apps, code is separate It's a better way to maximize production efficiency without creating new ones Is there a way?

P.S. As I said earlier, creating a hybrid app using Cordova is a performance problem.
