Frameworks for Xcode-------------------- `Binary frameworks`_ are available and ready to use in your XCode project, for`iOS`_ and `macOS`_. #. Download and extract the corresponding ``framework.zip`` file from the `Download`_ page #. Select **Build Phases** in your project setting and unfold **Link Binary with Libraries** #. Add *AudioToolbox* and *Accelerate* system frameworks (or make sure they are listed) #. Add ``aubio.framework`` from the unzipped ``framework.zip`` #. Include the aubio header in your code:   * in C/C++:   .. code-block:: c     #include <aubio/aubio.h>   * in Obj-C:   .. code-block:: obj-c     #import <aubio/aubio.h>   * in Swift:   .. code-block:: swift     import aubio Using aubio from swift---------------------- Once you have downloaded and installed :ref:`aubio.framework<xcode-frameworks-label>`, you sould be able to use aubio from C, Obj-C, andSwift source files.  Here is a short example showing how to read a sound file in swift:    .. code-block:: swift     import aubio     let path = Bundle.main.path(forResource: "example", ofType: "mp4")    if (path != nil) {        let hop_size : uint_t = 512        let a = new_fvec(hop_size)        let b = new_aubio_source(path, 0, hop_size)        var read: uint_t = 0        var total_frames : uint_t = 0        while (true) {            aubio_source_do(b, a, &read)            total_frames += read            if (read < hop_size) { break }        }        print("read", total_frames, "frames at", aubio_source_get_samplerate(b), "Hz")        del_aubio_source(b)        del_fvec(a)    } else {        print("could not find file")    }  .. _Binary frameworks: https://aubio.org/download.. _iOS: https://aubio.org/download#ios.. _macOS: https://aubio.org/download#osx
