Building my first iPhone app

On a rainy Sunday afternoon i finally got around to installing Apple's Xcode development suite on my Mac. My first degree was software engineering and i have done quite a bit of programming in the past (going back to my days on the Sinclair ZX-80!) though i haven't done a great deal in my job in recent years. Nearly all the programming i do these days is Perl CGI for myself, i have an on-line database of my book collection for example.

However i have felt like trying a bit of iOS development, i have vague ideas of an app to help people navigate the canals in the Midlands (canals being another interest of mine). So i installed Xcode then went through a "Hello World" exercise, the result you can see below running on an iPhone simulator. The app is very simple though is quite involved, its a bit more complicated than writing

10 PRINT "I AM THE BEST"
20 GOTO 10
RUN

on a microcomputer in Dixons and then running away...

When i have time i will get around to planning a canal navigation app. Time is the key constraint there.
