More importantly, we want to confirm we're not exposed to potential race conditions. Conceptually, our mobile app works like this: We invoke function foo when a mobile page is loaded. At the end of foo , we use setTimeout to invoke foo again (with one second delay) if a counter is greater than 0 . If the counter hits 0 , we load a new page. The timeout is saved in a variable. If a button is tapped

Unfortunately the documentation is so far nonexistent, and I'm having problems getting a simple graph to work. Using the following simple code to set up an audio engine graph, the tap block is never called. It mimics some of the sample code floating around the web, though those also did not work. let inputNode = audioEngine . inputNode var error : NSError ? let bus = 0 inputNode . installTapOnBus ( bus , bufferSize : 2048 , format :

The thing, which is not working for me at the moment, is tap to focus. I want the camera to focus and do whatever it does on my touched point, just like the real camera app does.
