Calling a swift framework from c or cpp code?

Thanks, this confirms my findings!

In addition you can wrap objective-c with cpp and call it from whereever you want to.

But does it work? I'm really interested to hear if it actually works in C/C++

I'll set up a sample project in the upcoming days and will let you know!

HI, I'm curious whether you got this working? We have a pure Swift 3.1 module we've been developing, and we're considering calling it from a cross-platform app built with Juce 5 (C++ library for audio/music apps). It seems like it should be possible, but just curious if anyone knows for certain.

Thanks in advance.

On an Apple platform? If so, this should be relatively straightforward. You should give it a try with a test project and see how you get along.

I tried it here in my office and didn’t encounter any significant difficulties. My main problem was that I had to remember to mark all the Swift APIs as

public

Here’s my Swift code from the framework:

import Foundation

public class Fff : NSObject {
    public func test() {
        NSLog("Fff.test()")
    }
}

And here’s the app’s Objective-C code calling it:

@import MyFramework;

…
[[[Fff alloc] init] test];
…

As a practical measure you may want to export your Swift APIs as Objective-C, because the interoperability story there is really nice. If you then want to call it from C++ you can use Objective-C++ to gateway through.

Okay, so the basic approach is to leverage Swift/ObjC++ interop.

Makes sense.

Thanks,
