Convert Android App developed in Java to iOS

We have developed a mobile app that connects through local network to a PC, does streaming to a PC app, and sends some pictures that it takes to the PC app. The app has stream/scan/end buttons. The scan feature takes some pictures, add them to a zip file, and send to the PC
The app is working fine on Android app, we will give you the java code and want you to convert to iOS
If you know java and iOS, this can take only 1-2 days to be done
We prefer swift for development
