Hi everyone, I am build a desktop app using JVM target, can I use Mac native library inside JVM ?

[Konstantin Tskhovrebov]

Yes!

Btw, JNI need C/C++ but I know only Swift :(( Anyway to convert Swift to C/C++?

[Sargun Vohra]

Here's a prototype of calling into Swift from the JVM: https://forums.swift.org/t/java-interoperability-effort/74969

But any time you're getting into some sort of FFI, it's helpful to familiarize yourself with C. Usually, regardless of language, FFI between languages tends to be done over a C ABI

[Sargun Vohra]

What's the library you intend to use? The level of difficulty here depends on the library

[Nguyen Duc Tuan Minh]

I want to access MPNowPlayingCenter

[Nguyen Duc Tuan Minh]

It is from Foundation

[Sargun Vohra]

This? https://developer.apple.com/documentation/mediaplayer/mpnowplayinginfocenter?language=objc

Looks like it's usable from Obj-C, so Rococoa is probably another option for you: https://github.com/iterate-ch/rococoa

[Sargun Vohra]
