Breakpoints Recap WWDC 2014

There was no WWDC ticket for me this year, but it was still a very enjoyable and busy week for James Dempsey and the Breakpoints. Here are some of the highlights from last week in San Francisco.

NeXTEVNT Cartoon Art Museum Fundraiser

In its third year, this fundraiser celebrates the heritage and history of NeXT, featuring black hardware as well as OPENSTEP and NeXTSTEP running in virtual machines. Even more fascinating is meeting up with folks who lived and breathed this platform from its early days—building apps with the frameworks that would evolve into Cocoa and Cocoa Touch.

As part of the evening’s entertainment, we played a short set of songs in support of the Cartoon Art Museum. If you are a fan of any sort of comics, cartoons, animations and the like, check it out next time you are in San Francisco. If you couldn’t attend the event during WWDC, you can still donate or join as a member.

 

LIVE near WWDC 2014

We had a great time on Wednesday night at 50 Mason Social House. The house was packed as Breakpoints from six different cities in five different time zones across two continents took to the stage to perform a show chock-full of Cocoa-inspired songs.

The evening served up an acoustic guitar sampler with a flight of Breakpoint guitarists—Nathan Eror (@neror) of Martian Craft, Jonathan Penn (@jonathanpenn) of Cocoa Manifest, and Ben Scheirman (@subdigital) of NSScreencast.

The show marked the debut of The Breakpoint Horns with Sam Davies (@iwantmyrealname) of Shinobi Controls on trombone and Daniel Pasco (@dlpasco) of Black Pixel on trumpet playing on Modelin’ Man.

(Any tenor sax players out there for next year? Please let me know.)

The talented Mr. Pasco also played electric guitar on that modern tale of momentary loss and redemption, Almost Dropped My iPhone. Conditional Breakpoint Uli ‘Object Alloc’ Kusterer (@uliwitness) of Elgato joined in with The Liki Song chorus. And of course, slide-advance keyboard legend Victor Alexander (@victoralexander) was on hand to keep that space bar hoppin’.

Thank you to all of the Breakpoints and also a big thanks to: Luke Scholefield (@lukescholefield), Adam Tow (@atow) and Rae and for taking photos and video; Daniel Steinberg () for recording sound off the board; and James White (@thecolourfool) for running the merch table.

(For more fantastic photos of the show—check out Adam Tow’s photo journal.)

Finally, an enormous thanks to everyone who came out to the show — your support is what keeps this going.  We had a great time this year and hope you all did too!

 

A Look Back at Alt Conf

On Friday, I presented A Look Back—the closing session for Alt Conf 2014.  With the surprise announcement of Swift earlier in the week, the talk took a look back to the beginning of the Objective-C era at Apple, tracing how technologies of that time have evolved into the environment we use today.  To accompany this look back, the talk also featured the first public preview of tracks from the soon-to-be-released James Dempsey and the Breakpoints album.

Thank You

The technology announcements of WWDC 2014 will have repercussions for us as iOS and Mac developers for many years to come.

Beyond learning about new technologies, the week gives us a chance to gather together and talk, to share ideas, some laughs and perhaps one too many drinks.

Thank you so very much to everyone who came out to see the talk and performances. Your support and feedback is greatly appreciated and means a lot to me—it was fantastic to meet so many folks this year.

With WWDC 2014 now in the past, it is time to turn my attention to finishing up the album and getting it out into the world.  Someone we are all familiar with said “Real artists ship” and that is my next order of business. •

March of the Breakpoints — ‘Goto Fail’, Chicago, DC

March was a busy month for James Dempsey and the Breakpoints, with a brand new song and video (ripped from the headlines!) and Breakpoint Jams at CocoaConf Chicago and Washington DC.

Goto Fail

Goto Fail is inspired by actual code, the code that caused a big security issue in iOS and OS X earlier this year.  Not that Apple has a monopoly on SSL issues in 2014 — The recent Heartbleed Bug only drives home the last verse in the song:

Don’t think your own code is some bug-free oasis,
It’s probably screwed up in a couple of places.

With Jonathan Penn (@jonathanpenn) of Rubber City Wizards on guitar, here’s the video of a live version of Goto Fail:


Chicago Breakpoint Jam

Chicago has been the home of a few firsts for James Dempsey and the Breakpoints — the inaugural Breakpoint Jam in 2013 and the debut of a new song “Goto Fail” in 2014.

Not since Murph and the Magictones has a Chicagoland Holiday Inn rocked so hard.

Joining in on the jam in Chicago were a number of familiar faces:


Washington DC Breakpoint Jam

The spring tour rolled on to Washington DC, where we played our set, managing to avoid the world-famous DC gridlock and partisan bickering.

Most of the Chicago crew was also in DC, with Jonathan Penn on guitar and Daniel Steinberg on slide-advance keyboard.

Keynote speaker Mark Dalrymple (@borkware) of Big Nerd Ranch sat in on Modelin’ Man, bringing a trombone solo to the blues tune for the very first time in its long history.


More to Come…

The next Breakpoint Jam will be at CocoaConf San Jose on April 25th.

Also save the date for ‘Live near WWDC 2104’ on Wednesday, June 4th, details to follow!

Hope to see you at Renaissance

(Jan 3, 2013: Updated ticket price and discount info added to end of post)

Renaissance, the iOS app makers’ conference, is happening in San Francisco from  January 21-23. It looks to be an excellent event and I am excited to be a part of it.

As part of the program, Chris Clark from Square and I will be presenting Beautiful Text, a session covering both design and technical aspects of text in iOS apps.

In addition, Renaissance will feature a special musical performance by James Dempsey and the Breakpoints.

My excitement for the conference goes beyond any particular session. I believe Renaissance will be an experience much greater than the sum of its parts. Here are a few things that have me looking forward to Renaissance:

The lineup of speakers is impressive.  I would go out of my way to hear any number of these folks speak individually. With so many people I respect and admire presenting, the event promises to be something special.

The conference format means that by hearing development, design and business topics woven together in a single track, you can take in everything without missing anything. I think bringing topics together that are often sequestered in separate tracks will spark a lot of interesting ideas.

Finally, I’m looking forward to meeting a lot of great people at the conference.  Twitter, Skype and email can be fantastic ways to keep in touch, but there is something about meeting people in person that has yet to be matched by communication technology.

If you are considering coming to Renaissance, the price goes up on January 1st, so now is a great time to book the ticket.   (Plus, if you live someplace cold and snowy, attending Renaissance can also be the literal rebirth of getting the feeling back in your fingers and toes.)

If you are already coming to Renaissance, please say hello. It would be great to meet you.  I really hope to see you there. •

TICKET UPDATE: The ticket price discount for Renaissance has been extended until January 8th!

ADDITIONAL DISCOUNT: Contact me if you’d like to use my discount code to save an additional $100 on registration for Renaissance.

Getting an app ready for iPhone 5

I was traveling the week between the iPhone 5 announcement and release. I returned from my trip champing at the bit to update my app WALT to use the entire 4-inch display, instead of being stuck in the letterbox ghetto. Updating turned out to be simple and straightforward.  Here’s how it went.

Out of the letterbox

The first step was getting out of the letterbox.  To do this, I upgraded the project to use the iOS 6 SDK and added a new 640 × 1136 launch image for the new screen size. Like all launch images, it needed to have a particular name: Default-568h@2x.png. There’s a lot of information encoded in that file name—the default launch image name, the screen height, the high-resolution size and the image format.

Enabling a feature by adding a specially-named image is a clever and compact approach, but it is not very obvious or discoverable on its own.  Xcode 4.5 helps by displaying a project warning and offering to create the new launch image for you.  (Although I see the warning now in a test project, I don’t remember seeing it when I updated WALT.)

Xcode 4.5 adds a few other features to support development for Retina 4 displays. The iOS Simulator has a new hardware device setting so you can test your app with the new size, even if you haven’t been able to get your hands on an iPhone 5.

When viewing storyboards, Interface Builder makes it very easy to toggle between Retina 3.5 and Retina 4 sizes using a newly-added resize button.

New resize button toggles storyboards between 3.5 and 4-inch views

If you are not using storyboards, Interface Builder still has you covered.  You can change the screen size for a top-level view in the Simulated Metrics section of the attributes inspector. This setting is also available with storyboards, but I have found the single toggle to be much more convenient to use.

Mostly done already

Since WALT uses standard tab, navigation and table views, there was nothing additional required to effectively use the additional screen space. Each table view became taller and now displays more content. I could have released the app as-is, but wanted to do a few tweaks.

On a Retina 3.5 screen, the film detail view in my app adjusts row heights in certain cases to improve the layout.  I needed to make different adjustments for Retina 4 screens, so I needed to tell the two screen sizes apart.  The new screen size is not a different user interface idiom—just a taller iPhone. For screen size, the highest level API available is to use UIScreen to get the height of the main screen:

 CGFloat mainScreenHeight = [UIScreen mainScreen].bounds.size.height;

I‘ve already seen a number of online examples that use the screen size to add convenience category methods to UIScreen or UIDevice.  In my case, I checked the screen size inline in the one place where it was needed.

Screenshot of the film detail of 'Partysaurus Rex' in the app WALT.

What Up, Fishes?!
The newly added ‘Partysaurus Rex’ looks nice and comfy, all stretched out on a beautiful iPhone 5 in the new version of WALT.

Although my experience was quick and painless, the amount of work needed to adapt an app for 4-inch screens varies greatly depending on its contents.  The iOS Human Interface Guidelines document suggests different approaches for various situations. It also makes a very important point that applies to all apps.  An app should remain the same app, with the same features and interaction, regardless of which screen size it is being displayed on.  But, when displayed on a 4-inch screen, it should reveal more of its content.

In summary, getting your app to stretch out to the full iPhone 5 screen is as easy as updating to the latest SDK and adding a new launch image.  Getting your app to look great, however, will depend on how customized your views are.

For me, I found that getting the app ready for iPhone 5 took less time than preparing the new set of taller screenshots required for the App Store. •

WALT 1.0.1 is available now in the App Store with iPhone 5 and iOS 6 support.
