The simplest things are often the hardest.

So had a few more successes last week.

I got CoreAudio/AudioUnit Swift code running in a XCode Playground. This was a big help in trying to understand how AudioUnits work, and how to work with C Pointers in Swift.

I also got a very simple CoreLocation application running, which retrieved the compass direction. [That is probably the easiest thing I have done so far.]

Now I have to vent just a little. In developing this app for iOS I am completely baffled about one thing about trying to develop and app for an Apple platform.

I really wish Apple’s documentation for development was a lot better. I cannot think of a single thing I have yet to try to do on iOS or macOS yet, in which I did not have to look up a tutorial or an example for how to do something from a third party source.

Compared to Microsoft’s MSDN it just seems that Apple’s developers’ documentation is pretty thin.

Sure Apple supplies some guides and sample code. However, I tend to find Apple’s choice of a sample code examples to be a little esoteric. Especially when I just happen to need just a really brain-dead example to help me grasp the concept on how I should use a framework.

I don’t know, I just find it funny.

10,000 more baby steps to go.

Ok the 4^th of July through me off, but after two weeks there is a lot to update about.

First, I finally got a basic Structure app working on my iPhone. Photos below.

The biggest challenges what getting use to YpCbCr color space. Also, there was a small bug in the Structure SDK that cause the Synchronized frame calls not to work. However, considering my end goals it was not critical to use synchronized frames, yet.

Also I was able to get a very basic Audio and MIDI application running on the iPhone. This was crazy because I had to pull information from multiple sources to figure out how to do that. The current Apple example, is pushing AVFoundation, but I needed CoreAudio.

The point is, I am just glad I have been able to accomplish baby steps in both areas, using the sensor and generating sound. Now there is only like 10,000 more baby steps to go.
