The sessions are always VERY informative, but it is also a excellent chance to not only meet with other Mac/iOS developers, but you have the chance to talk one on one with the very people who are writing the software and API’s (Application Programming Interface) that we write software for/with.

Apple does make the videos of the sessions (along with the slides) available to everyone that attends, and allows those that didn’t attend to purchase the videos.
Before last year, these videos usually took around 6 months to become available, however last year they had them released within a month.

This year Apple TOTALLY outdid themselves and have released the videos all today!
That is LESS than 1 week!
Not only did they release everything within a week, but Apple has made all of the videos and slides available to ALL registered developers (even the free developer accounts) FOR FREE!!! That is a $500 savings for those that couldn’t attend!

I only have 2 things to say…

First: Good bye to my Hard Drive space (The videos are available in HD and Standard formats this year)

and Secondly… Classy Apple! VERY VERY CLASSY!

Reminder: Even though the videos did not cost this year, they are still covered under an NDA that you agree to when signing up for a developer account. Don’t make them sorry that they were so giving.

Special thanks to Jeff LaMarche for guiding me in the right direction to figure this out. You can find his blog at: http://iphonedevelopment.blogspot.com/

This issue came to play when I needed to do a fetch request from Core Data and then run a couple of Predicate “searches”/”filtering” on the data.

My original thought was that doing a single fetch request and then running my different predicates on the returned set of objects would have better performance then doing multiple fetch requests since I would only have to pull from the Core Data SQLite DB once and then I would have everything in memory and I could just simply manipulate it.

Turns out that this is HIGHLY incorrect.

If instead you just do multiple fetch requests and implement your predicate into your fetch request, that Core Data and SQLite are smart enough to scan the records more efficiently and without causing Core Data Faults to fire.

This gives a MASSIVE speed increase!

So if you are ever doing something similar, make sure to check this method and see if it to can speed your app up.

This book is great for new iPhone developers as well as experienced ones.
You will need some Objective-C knowledge, but if you have some OOP (Object Oriented Programming) experience you should be ok with picking up an Objective-C book as well for as you work through the book.

If you are in a B&N stroll into the Geek, err, I mean Computer Programming section and look for the book.
Feel free to buy a copy to support my good friend and author of the book, Jiva DeVoe.
If you can’t get yourself to that level of geek, at least pick it up and look at the ‘Credits’ page, right before the Table of Contents and then you can go around to all the geeks in that area and say, “I KNOW THIS GUY!”

This makes 2 iPhone development books that I have been involved in, each one with more of a role than the last, however I can safely say it will be my last as after being involved with the book writing processes and having the author be a close friend of mine, I don’t really have a desire to write one myself (unless it’s an offer I just can’t refuse).

KidFlix is for parents with small children. KidFlix stops kids from accidentally activating the on-screen controls while listening to audio or watching videos on your iPhone or iPod Touch. Therefore eliminating accidental exits, fast-forwards, etc and therefore eliminating the need for you to constantly fix the problem.

KidFlix is not meant to be a substitute for proper child care, but instead to be a helping hand in keeping your child entertained.

As a parent of a young child I know how valuable of a tool this program can be when you are at say a restaurant and your child starts getting bored.

You can purchase KidFlix for $1.99, directly from the App Store by following the URL:

I no longer work for PayPal and I am now an independent Mac and iPhone developer!

Along with this change, me and my wife have decided to move us and our son back to Utah so we can be closer to family.

We move into our new place in Utah on Sept 1 (1 1/2 weeks from now).

We are really excited about both changes.

WWDC (Apple’s World Wide Developer Conference, in case you don’t know) was amazing!
This was the first time that I have been able to justify going (it’s not cheap) but man was it great.

I had the chance to meet so many amazing people that I talk to all the time on Twitter, but now I got the chance to meet them in real life.

Besides all the great developers and parties, it was a chance to learn about new and upcoming enhancements to the Mac operating system and the iPhone, as well as learn the best way to do certain things in code, coming from the people that write the language!

Apple also offers what the call labs during WWDC.
Labs allow you to take your code and sit down with an Apple Engineer that works on whatever particular topic you want, and they are there to serve. They will look over code and tell if you how you could have done it better, or they will help you debug an issue you are having, or anything else.

There is so much information flying at you all day that it can be overwhelming at times.

And when the sessions and labs end each day, WWDC does not end….
I have never seen more back to back, double/triple booked parties in my life.
Parties that go until all hours of the morning.

So with sessions and labs all day and parties all night, by midweek you are the walking dead but it doesn’t stop the fun. (and I didn’t even go out every night!)

Around the end of the week Apple throws a big party and this year had the band ‘Cake’ come and perform.

Overall it was a GREAT time and I can’t wait until next year, yet it is always nice to come back home to family as well.

We are talking about Nancy coming along next year and being able to tour San Francisco while I am in the sessions.
