How to call swift and its functions from qt using c++ as wrappers ? I don't want any suggestions and want only the exact method to this solution.

Hello and welcome.

That is quite demanding for a first question, and you may not like the answer. Calling e.g. Swift functions has nothing to do with Qt, you will do it by however you choose to call them from C++. Which is a question for a Swift/C++ forum, not Qt. Since you don't want suggestions I won't tell you how to do that, but there are plenty of answers/examples out there on the web.

Ok, I might have been rude, can you please tell me a suggestion ?

:) Just Google as I did for call swift function from c++. Read through/follow whichever of the suggestions you like. From what I can see as of July 2020

First, while it looks Swift will have a great support for C++ in the near future, for now you will need to create simple C wrappers to your interfaces.

Unlike C++ or Swift, Qt is not a programming language. It is just a set of libraries/toolkit to be used from a C++ program. If you are using Qt .pro files/Creator for your building:

• Put any required #includes into your source file(s).
• If necessary for these to find the .h files in some directory, alter INCLUDEPATH (.pro file) to tell it where to find them.
• Alter LIBS (.pro file) to specify linker arguments for your compiler to specify the directory where whatever Swift library files are situated and what library file names need to be linked with, e.g. like:
  LIBS += -L/path/to/swift/C++/link/libraries/directory -lname_of_swift_library_file

You will have to see which of the above steps are relevant for Swift.

Thanks, but how to use it to wrap swift into c++? The given instruction on the README.md file is only about Java.

@1km7kt1hi
The two links I gave you both claim to show/offer bindings from C++ to Swift. And there are other examples/links from the Google.
