If you just updated to Xcode 3.2.5 and iOS SDK 4.2, you might find that your existing projects do not compile. This probably doesn't surprise you as it's been the way for every SDK update as far back as the beginning of time (at least in the Jobsian calendar). Thankfully, with Xcode 3.2.5, you can set your base SDK once and for all and it should work for all future releases.

But first things, first, here's the error I received while trying to compile one of the early projects from my iOS SDK workshop: "error: there is no SDK with the name or path 'iphoneos4.1'"

Last week I was in New York, speaking at the Future of Web Design conference, where I presented the second day opening keynote and taught a new one-day workshop on iPhone Design & Development.

I attended both days of the conference and loved the other sessions as well as the venue, and, of course, New York, where we got to see Driving Miss Daisy with James Earl Jones and Vanessa Redgrave, eat at Bubba Gump's overlooking Times Square (what an experience), and enjoy the culinary delights of the excellent The National restaurant (where we had the most amazing Branzino), and knock back a couple of espresso martini's at the W Hotel (they serve the best ones I've had anywhere).

I was trying to install PhoneGap iOS on my new MacBook Air but got an error when I ran the PhoneGapLibInstaller.pkg installer. It was telling me that I didn't have Xcode installed when, in fact, I did. I just didn't have it installed in the default location (/Developer).

(Since I usually have several versions of Xcode on my machine at the same time, I've taken to installing them off the root in descriptive folders – e.g., Xcode3.2.4iOS4.1, etc.)

It looks like I'm going to go from never having attended a TED event to attending two within a month of each other. I'm hugely excited to have been invited to attend TEDxAmsterdam at the end of this month and, a week after that, I'm going to be attending TEDxBrussels.

The sessions at TEDxAmsterdam range from Nanobiosym – the convergence of physics, nanotechnology and biomedicine – to the presentation of two arias by a certain world-class soprano.

I will be teaching my 3-Day Introduction to iOS Development workshop this month, November 24-26, 2010, right after I return from giving the second day opening keynote and teaching a one-day iPhone workshop at Future of Web Design in New York. The venue is the beautiful Lighthouse Arts in central Brighton (UK).

This intensive course will give you a solid foundation in developing with the iOS SDK (for iPhone, iPad, and iPod Touch), Xcode (both 3 & and the upcoming 4), and Objective-C. To see a more detailed outline of the course and get all the juicy details, please see the course's web-site.
