I was having a problem with no sound on either my phone or the simulator. I had traced with print commands and could see the method was executing in the code, but still could not hear anything. Here was what I found solved my issues:
Simulator: My “Sound” folder was not adding as group folder, it was blue instead of yellow. Once I checked the Group option with Copy Items if Needed on the Options Panel. Voila, sounds on the sim.
Phone: This is a system sound, I had my phone toggled to mute. I could hear my music, so it didn’t click that I had the mute toggled thus muting the system sounds.
Cheers, on to Lesson 4.
