OsX portation of Apps

Is it a big (expensive) problem, to bring my apps to OsX?

Explain...

Hello,

My dear son Pauli inherited an iphone 13 to me.
I ask myself and I ask my dear friends here, if it is easy to port the apps, I developed with ai2 to it. Or is it expensive?

Thank you

Hi, you like to port your iOS apps made with AI2 to MacOS(OsX)? Well that is not possible.

I mean, I made some nice Apps for Android and want to use them on my new Iphone 13.
