9:30 - I know that everyone is waiting with baited breath! Well, I have to say, “not yet”. I was all ready to enable rotation (2nd try), when I realized I needed to do my scroll view memory usage optimization first. Unfortunately, that exposed some previously hidden memory management issues, which forced me to learn some new tools and finally figure out Objective-C memory management. Now I seem to have that solved, so I can check it in and get on to rotation. Except, wait, I did get the app to crash last night, so better look at that first…

10:00 - Ah, the debugger’s nightmare. Console log was gone, crash log no help, and can’t reproduce it. Oh, well, sure I’ll see it again later. Time to check-in!

10:10 - Are the “blog” gods as powerful as the “demo” gods? Just as soon as I wrote the last paragraph, I crashed the app! Let’s see why I won’t be able to debug this one…

10:30 - Again, no console log, crash log no help. Gotta see if I can reproduce it while plugged in… YES!

12:44 - Got a bunch of stuff fixed. I want to write it is ready for check-in, but I know now that I wrote that, something will crash…

14:09 - Cleaned up and ready to check-in!

Just about to Alpha with my first app.  One bug and one enhancement to go…

Today is Apple’s iPhone OS 3.0 announcement. I’ll capture my thoughts here.

The iPhone OS 3.0 Announcement Scorecard is pretty good. Hopefully we’ll see more than a few of these!

Here we go:

Overview:

• 800,000 downloads of the SDK
• 50,000 iphone developers
• Gameloft has had 2 million downloads

• 96% of submissions are approved
• 800 million app downloads (and the rate seems to be stable, perhaps even accelerating)

Q&A

• Why no flash?
  • Can’t tell us
• Will peer to peer work with other devices?
  • It’s limited to Bonjour (so, Macs, I guess?)
  • No file or music sharing
• Tethering?
  • Apple is building support in.  
  • Sounds like carriers make the decision
• Push notification uptime guarantees?
  • No
• Addressing current OS “lagginess” problems?
  • Definitely
• Could you serve audio files over bluetooth, could you move them?
  • Very unsure “probably not”
• Approval process
  • There have been issues, e.g. content available to children.
  • Working with developers to improve it.
