Is it possible to "port" an Android project (.java) to IOS and not have to redo it all over again?

Question

Java

Hello.
I am currently working on an Android project in JAVA.
And then the problem arose of how to transfer the same project to IOS in the future and not write it again on SWIFT
Thank you

Answer 1

You can act like Google in gmail. They write in Java and share up to 80% of their code between platforms using j2objc. There is a Java -> Objective-C translation. But such code is quite difficult to write. The translated part must be completely independent of android. Part of the Obj-C/Swift code will have to be written.

Answer 2

No way. You either write two projects for different platforms in native languages/frameworks for these platforms, or use cross-platform solutions (PhoneGap/IONIC/Titanium and others like them).
PS Look also at the answer of Denis Zagaevsky, also a good suggestion.

Answer 3

You can write Qt for android and ios.

Answer 4

move as much logic as possible to the server
