Yesterday I let my Mac Mini upgrade to Mavericks and Xcode 5.
Today, after eventually figuring out how to get the new Finder to display my files in descending modified date order, I tried rebuilding my working WIP (I am just finishing up the last game fields). It built fine. But when I tried to play it, it did not handle the input files for the fields properly. They are stored in a binary format and I used .bin as the extension. Until today, this had not been a problem and the app ran in Mac and on my iOS devices just fine.
Today, it would not load the files properly. It worked if I used the text files (reading in text mode) with .txt extension. So I tried the binary with a .xml extension and it worked fine. And it also liked .dat.
But, do NOT use any files in your media directory with the extension .bin and expect them to behave properly when built in Xcode 5 in Mavericks.
The files are placed on the device and are visible to the app, but don't load properly.
Also, I highly recommend not letting Xcode update the Facebook SDK (which it will ask every time you start up). I do not know if the updated SDK is compatible with AppGameKit and don't want to test on my system right now. I am too close to publishing to want to mess that up.
