Spelling iPhone App sent to Beta Testers January 28th, 2010

I am pleased to say that I just sent my first iPhone app out to some friends to beta test. I expect to forward it along to Apple for inclusion in the App Store some time in the next week or two.

At this point, I am far more comfortable with Objective-C and the Cocoa class hierarchy than I was even a month ago. I still think Objective-C is awful. You take a nice functional Smalltalk-ish language, you throw away most of the functional, you pretend like you have garbage collection when you don’t, you strip out any form of execution control, you add some funky compiler pragma-looking things (including one called synthesize that only fabricates about half of what you’d want it to build), you change the semantics of ->, and then you interleave it with C! Wahoo! Instant headache!

But, after I found the for-each sort of construction, my code got quite a bit simpler. A whole bunch of loops like this:

NSEnumerator* ee = [myArray enumerator];
MyItem* item;
while ( ( item = (MyItem*)[ee nextObject] ) != nil ) {

went to this:

for ( MyItem* item in myArrayOrEnumerator ) {
