Hi all,

I’ve written some some code in Swift using the Accessibility framework and want to use this in one of my Juce projects. Googling around I could only find advice how to use c++ code in Swift projects but not the other way around.

In my case, I simply want to call a swift function from c++ and returning a simple boolean.

Thanks  
Stefan

You can’t call Swift from C++ (that I’m aware of) but you can from Objective-C++. So instead of adding a .cpp file to your project, and a .mm

Then you’ll need to follow the steps here: [https://developer.apple.com/documentation/swift/imported\_c\_and\_objective-c\_apis/importing\_swift\_into\_objective-c](https://developer.apple.com/documentation/swift/imported_c_and_objective-c_apis/importing_swift_into_objective-c)

If you keep your header pure C++ then normal C++ can use your function / class. Keep all the Objective-C++ that interfaces to the Swift in the .mm file.

You will need to be outside of what Projucer can do, so you’ll need to maintain your project yourself.

Hi, see [Call swift code from objc code in … | Apple Developer Forums](https://developer.apple.com/forums/thread/129282) re. calling Swift from CPP.
