Is it possible to port (or maybe some other option) a JAVA application from Android to iOS?

Question

Java

The situation is classic.
There is a finished product running on Android. Nothing extraordinary. Buttons + fields, remote DBMS, BT / WaiWay.
No graphics, etc.

And as for the conduct, the same thing was requested "now on iOS".

What to do? Run to run to learn SWIFT? Or are there alternative ways out of the situation?

Thanks in advance.

Answer 1

I myself have never used it, but there is such a thing as the MultiOS Engine

Create iOS Apps in Java
Port your existing Android App, or build a native Cross-Platform App from scratch

Answer 2

If the Android application is native, written in Java, then yes, rewrite it from scratch in Swift.
If written in React Native, then porting to iOs is easy. Add multiple configs

Answer 3

Look towards Xamarin.
Nothing extraordinary, but the code will match on both platforms.
And yes BT / WaiWai confuses me. On apples, this is more difficult. Although the basic functionality of turn off request status is there.
