File permission error in Xcode using python

I am running a python/kivy compiled app in Xcode, but it raises an error when I try to save some audio bytes to an audio file. I have done this successfully in my IDE, so I don't understand why it isn't working in Xcode.

Here's the concerned section of my code:

test = mic_callback()  mic = get_input(callback=test.record_audio)  mic.start()  time.sleep(5)  mic.stop()  recorded_frames = audio.get_audio()           sample_rate = 44100      wf = wave.open("audio.wav", "wb")  # create an audio file object in 'write bytes' mode (as frames file stores audio in bytes)          wf.setnchannels(2)  # set the channels in the audio file          wf.setsampwidth(2)  # set the size of each sample in bytes (2 bytes in the case as each sample is 16 bits)          wf.setframerate(sample_rate)  # set the frame rate          wf.writeframes(b"".join([]))  

Here's the error message:

Why is a Permission Error raised when I try to access the 'audio.wav' file?
