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, and
Swift 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")
}
