iOS Developer News Roundup: What’s New in Objective-C and Foundation in iOS 7, NSBrief, and My Appventure

What’s New in Objective-C and Foundation in iOS 7

'iOS 7 Feast' table, featuring Objective-C

The latest post on Ray Wenderlich’s ever-so-useful iOS development site at the time of this writing is What’s New in Objective-C and Foundation in iOS 7, which is the Reader’s Digest version of a chapter from their new iOS 7 by Tutorials book. It gives you a quick look at the following new goodies:

  • Modules: “We’re all guilty of being lazy developers though, and nobody has time to tune their PCH [pre-compiled headers] file for each project they work on. That’s why modules were developed as a feature of LLVM.” For more about modules, see this video and these slides from the 2012 LLVM Developers’ Meeting.
  • instancetypeIt’s the return type that replaces id (and the problems that come with it) in most cases.
  • NSArray::firstObject: Arrays have a lastObject method, and finally, there’s a firstObject method, which gets around the error you get when you try to access element 0 of an empty array.
  • Built-in Base64 encoding methods: Now you don’t have to go look for a third-party library or roll your own.
  • NSTimer tolerances: Lets you specify how late a timer can fire after its scheduled time.
  • The NSProgress class: “In essence, NSProgress aims to deliver progress reporting throughout Objective-C code, neatly separating the progress of individual components. For example, if you perform a few different tasks on some data, then each task can monitor its own progress and report back to its parent task.”


nsbriefNSBrief bills itself as “A brief Podcast for Cocoa Developers, discussing interesting developer-y topics” with 108 podcasts under its belt dating back to October 2010.

  • 015: Dave Klein: The Joys of CocoaConf – Today’s guest is Dave Klein, the lead organizer behind the oh-so nice CocoaConf conferences for iOS and Mac developers. If you’re looking for a high-quality conference closer to home, then you need to check out these events.  CocoaConf travels the country and hosts regional conferences, making it much more affordable for Indie developers. CocoaConf focuses on quality and community, listen in to find out why I enjoy their events so much.”
  • 014: Grab Bag: Clarity, App Annie, and More – “On today’s show I talk about how I use a service called Clarity to GIVE and GET professional advice over the phone.  I also provide a quick update on Quotely.”
  • 013: Xavier Veyrat: Cooking Up Apps with AppCooker – “Today’s guest is Xavier Veyrat, designer of AppCooker, an amazing tool to manage all of the pre-production work that goes into your app.  Cook up interactive prototypes, icons, keywords, and even pricing models.  If companies like Disney, EA and even Apple are using AppCooker to make their apps, then yeah… you might want to check this thing out!”
  • 012: Jonathan Penn: UI Automation Jedi Master – “Today’s guest is Jonathan Penn, an Indie app developer, tech-talker, author and contract consultant.  Jonathan has become an authority figure on the subject of UI automation and testing for iOS and he recently authored a book on the subject.  Whether you’re working on an app idea, or you do consulting to pay the bills, there’s something for you to glean from Jonathan’s experiences on today’s lighthearted interview.”
