Podcast #41 – “Megabytes of Who-Knows-What”

Apple updates Xcode 4.4, seeds the first point release for Mountain Lion, and somehow manual symbolicating of crash reports has become broken.

iCatalog+

Our partners at International Color Services (ICS) have been rather busy throughout the summer. The main reason is that we released the next major update to the iCatalog.framework, adding several new features which are nowadays a “must have” for a state-of-the-art digital catalog experience. We call it simply iCatalog+ because it offers way more than just catalogs.

Several catalog clients already have their free iCatalog+ on the App Store, you should definitely check these out.

Software Update Server Guide

Once you get to a level of having more than a single Mac you might find it a bit of a hassle having to download and install all updates for all your Macs from Apple over the Internet. When you check for updates then every Mac will by default connect to Apple’s catalog of updates and download the updates from there.

This is where a Software Update Server (SUS) starts making sense. Let me share some things that I learned over the past 2 days investigating how to best set this up for our work group in the office as well as for all the Macs I have at home.

iPhone 5 Fake Rumor Roundup

Current rumors about the next iPhone are that it will have a 4″ screen, a smaller SIM card and will probably start with pre-orders on September 12th. We’ve heard all that, that’s old news.

Following in the footsteps of the fake Asymmetric Screws rumour which was planted by Swede Lukasz Lindell (and friends) I felt a sudden wave of sadness crush on me when I realized that I simply lack the amount of creativity that goes into constructing a good Apple rumor. If only I was creative enough to think of several such good and believable rumours, I could probably make a living just from the blog traffic alone. #linkbait

So I vented this frustration on Twitter and to my surprise many people took this as an invitation to chime in and also play the game. Here’s a roundup of the best fake rumors I’ve heard. If you respond with a good one I’ll add your contribution as well.

Smart App Banners

How often do you get annoyed by the following? You look up something on Google on your iPhone and you find an answer in a forum. When you click-through the search result the forum does not just show you what you were looking for, but it pops up a large annoying alert informing you that with their native app the reading experience would be so much nicer. And it does so even if you gave in some time earlier and had already installed the app.

Fortunately it has been announced that Apple will include a smart solution to this problem in iOS 6. Safari will gain the ability of automatically displaying such banners.

Cubed CoreAnimation Conundrum

One of the big mysteries of CoreAnimations are 3D transforms. You might have seen them used in popular apps like Flipboard (page turn) but there are hardly any good tutorials in how they actually work. In fact, you find only one from 2008 what was written when OS X Leopard was still around.

I blame that there are several things that are counterintuitive about using 3D transforms and perspective with CoreAnimation why not more people play with it … and then write up what they learned in some useful guide.

Session 421 Core Animation Essentials  from WWDC 2011 had an example of 6 squares that would animate into a three-dimensional box that the presenter could even rotate around. That inspired me to figure out how to do this as well, and with the help from several people on twitter I was successful.

Unit Tests Don’t Bite

You might have heard about the term “Test Driven Development”. The idea is – as I understand it – that for every problem you find in a component of your apps you create a Unit Test that fails. Then you fix the bug. The Test now passes. This can be carried further by writing your test cases even before you write any implementation code.

Especially when encapsulating your frequently-used code in static libraries or frameworks those unit tests can help save you a lot of grief. Imagine adding some nifty new feature to inadvertenly  introducing a bug that would break some other existing functionality. If you run the unit tests they would show you immediately that your change broke something.

In this blog post I’m summarizing a couple of things to help you get your own unit tests started.

A Taller iPhone is a Giraffe

Blogger Mark Gurman from 9to5Mac caused quite a stir when he showed screen shots showing that Apple had secretly updated the iOS Simulator to be able to deal with the rumored higher resolution of the next iPhone. His hack involved some nasty code injection that had previously been used to demo iPad on Retina resolution long before the iOS Simulator supported that.

The point of his article was that the main visible difference between the 5.x and 6.0 springboards when having more screen space available. On iOS 5 you always get 4 evenly spaced rows of icons there while on iOS 6 you will get an extra row of icons with no increase in spacing.

Because Mark did not give detailed instructions as he achieved the result (to “protect his sources”) developers all around started to investigate and Cédric Luthi beat everybody to the punch, revealing a method that is so simple, even I was able to follow it.

Softly Killing iPhone 3G

The latest version that ever ran on the iPhone 3G was iOS 4.2.1, but even though iOS 4 brought multi-tasking to the platform the iPhone 3G never got that. The iPhone 3G had been introduced in June 2008 with 16 and 8 GB capacities. Of these the 16 GB was discontinued after 1 year while Apple kept the 8 GB model around as the cheaper iPhone. This was discontinued on June 4, 2010 when the iPhone 3GS took its place as the “cheap one” while the iPhone 4 became the “current model”.

Long story short: The iPhone 3G has been discontinued 2 years ago. But there is also a technical reason why 2012 will be the final nail in the coffin that buries the iPhone 3G: The deprecation of armv6.
