OK, that's good to know.  However, when I do:

NSURL *temp = [NSURL fileURLWithPath:[@"~/Desktop/Songs.xml" stringByExpandingTildeInPath]];
if ([myDictionary writeToURL:temp atomically:YES] == YES) {
NSLog(@"worked");
} else {
NSLog(@"failed");
}

it always outputs "failed".

Any other ideas?


Only brute force to narrow down the problem. Make sure it works with an empty dictionary. Try writing to a dictionary. Try removing half the dictionary entries. Try removing all but one of the dictionary entries. Try to find a dictionary that works and a slightly different dictionary that doesn't work, and study the difference between the two.

Is it possible the dictionary or one of its subobjects contains something that the -writeTo methods don't like, i.e., something that is not an NSData, NSDate, NSNumber, NSString, NSArray, or NSDictionary?

Well, the dictionary I'm pulling all this information from is the iTunes Music Library.xml file, which contains nothing but strings, integers, and dates.

Perhaps there's another way to tackle this problem. All I need to do is inspect the structure of my dictionary. From what I've seen in the debugger, there's no clear way to get a list of all the key/value pairs of a dictionary (or array, for that matter) while debugging. Is there? That would be preferred.

Thanks!

Dave
