Meeting Kickoff and Updates
We all missed Mike Z. at this month’s meeting and hope he had an awesome time at the conference in Boston! We’re all looking forward to hearing some of the megaton of info he soaked up. That said, Curtis did a fantastic job in his absence and we, as always, got the benefit of great talks and surrounding discussion.
Here are some of the intro points of interest: • The next Side Project Saturday has been moved to avoid conflicts with the holidays: (Nov 22 and Dec 13) • CocoaLove was epic and now the videos are now being posted! • The Kotaro-led Designing & Planning Your iOS App” Workshop was awesome…lots of “rubber meets the road” insight and guidance. • Tom will be leading an Intro Swift Workshop soon which is bound to be equally succulent! Anyway, be sure to hit the Meetup site (http://www.meetup.com/PhillyCocoaHeads/) to stay up on other awesome upcoming events. Dennis, get on with it!
Ok…below is a quick recap of the talks and links to resources for more info.
Show and Tells
Jeff Kempista - iOS 8 Extensions
Jeff gave a raw cool talk on his experiences with iOS 8 Extensions. Thanks Jeff!
Here are some of the points from his talk and the discussion that came up around it: • While extensions have to be bundled with an iOS app, they run completely separately and do not require even one launch of the app they are bundled with (called the containing app) to be presented/used by iOS. • While they can’t pass messages to the containing app, they can share code and data with it as long as any code is bundled in a framework and any data is placed in a persistent store within the bundle (e.g. a SQL Lite DB file, Core Data persistent store, NSUserDefaults, plist, etc.). Keep in mind, though, not all APIs are available to extensions. • If the extension crashes, iOS will just bypass displaying the corresponding view as an option within the context of the extension point (e.g. For Share extensions, that would be in the view that presents the iOS sharing options like FB and Twitter). • Share extensions can even launch other apps! • There is a checkbox (and associated Xcode warning) in one of the build settings pages that I couldn’t find even after adding a couple extensions to a test project. However know that if it’s not checked, Apple may reject your app containing the extensions. This stack overflow post was the only thing that sounded close (http://stackoverflow.com/questions/25949108/warning-during-archive-app-with-ios-8-extension-in-xcode-6) but the checkbox wasn’t the one Jeff showed. Hit Jeff up for details or chime in if you have more info. • For an example of Action extensions, the 1Password app (https://itunes.apple.com/us/app/1password-password-manager/id568903335?mt=8) contains at least one of them. • Jeff also posted his slides at https://dl.dropboxusercontent.com/u/12567901/Extensions.key

Kostas “Gus” Nasis - Rapid App Development Framework
While technical issues with posting content to the screens got in the way, Kostas and Sinae presented a way-cool content-rich app they developed for the ABRAAJ Group using lots of custom controls and web views (in a way that even Kotaro approves).
Kostas started to present their really cool idea of them developing a way to describe a UI using a JSON-format which describes all the attributes of the views. However, the talk was cut short so we’ll look forward to his presentation next month.
Kostas “Gus” Nasis - Pixate Demo
Here Kostas demoed Pixate—a very slick tool for mocking UI interactions and animations.
Here are some of the points from his talk and the discussion that came up around it: • The drag-and-drop UI is similar to IB where you can drop what they call Layers (that represent views) onto the canvas and then associate different gestures with those layers. • You can bind animations and other UI behaviors in response to user triggers of the corresponding Tap/Pinch/Pan/etc. gestures associated with the layer. • You can group the layers in ways similar to creating a view hierarchy. • There’s a simulator view that shows how the prototype would look on a device and the Pixate app allows you to do the same thing with an actual device just as Xcode does with real app code! • While you can place other rectangles in the editing workspace to represent other scenes/screens, there’s only really one canvas so it was only designed to represent one screen per file similar to xibs. • Also, they may be building a capability to generate code from the prototypes you build. • Kostas also mentioned that the videos on the Pixate site are short and the ramp is quick.

Hugh O’Neill - Kickstarter Feedback
Hugh let us in on his latest initiative associated with his Happ Puzzle App, called Happ Greeting!
Here are some of the points from his talk and the discussion that came up around it: • Happ Puzzle allows someone to send scrambled photos to friends to be reassembled like a puzzle. • In Happ Greeting, Hugh has expanded this idea to allow the binding of a message to the photo being sent such that when you assemble the photo, the message proportionally gets descrambled…cool! • Several people gave really great feedback and I wish I remembered so I could mention by name. You all know who you are…thanks for all the great input! • Hugh also gave due kudos to Curtis who, at the design workshop, helped him refine his approach in associating the puzzle progress to the corresponding message assembly. • Hugh wants to release to the App Store soon so we’ll keep everyone posted.
Curtis Herbert - GPS library
• Curtis graciously deferred his talk due to time constraints but we are absolutely holding him to next month’s meeting!
Andrew Theken- Confessions of a C# Fanboy: Using Xamarin to build your next iOS App.
Andrew, Andrew, Andrew. Thursday, we found out that, while remaining married to us, has been seeing another language…C#. While I’m not sure we’ll seek counseling, we still love him and will certainly continue to stay married.

PhillyCocoa is the Philadelphia area Mac and iPhone programming group, a chapter of the worldwide CocoaHeads. All skill levels are welcome. The only requirement is an interest in Apple-related technologies and moderate tolerance for geeking out.
The main CocoaHeads presentation-style meeting is the second Thursday of every month. We also hold a Side Project Saturday event the last Saturday of the month. For more on our events see our Meetup page:
We are always looking for feedback and suggestions on what topics to discuss at our meetings. Please reach out if you have any comments.

An interesting look at how Apple negotiates and how they usually win. Very well done article.Read More
There will always be an argument about this. More so now with the new features for webviews in iOS8. There’s a potential middle ground but I find it to be problematic for people to think web apps are some obvious shining unicorn for the future of mobile development. Very few developers can get away with pretending a web app can mimic a native app.Read More
CocoaLove start off as a #JFDI reaction to having no iOS/Mac conference in Philly. What an amazing eye-opening event it became. It was a blast to organize and observe as it became a big hit with everyone who attended. We have a lifestream up although not sure for how long.Read More
How One Boy With Autism Became B.F.F.’s With Apple’s Siri. A really touching reminder that technology can be magical…and Siri isn’t as useless as some of us make her out to be.Read More
Its probably good thing to read the tea leaves here and know Apple is VERY serious about Swift. Also nice to see Drexel on the list of Universities running classes on it. But I’m not biased at allRead More
