How come reading from a plist fails in my iOS application?

I am trying to create an NSMutableDictionary containing a list of animals in my iOS app with this function.

// puts animals into dictionary
- (void) putAnimalsFromPlistToDictionary
{
    NSBundle *bundle = [NSBundle mainBundle];    
    NSString *path = [bundle pathForResource:@"myAnimals" ofType:@"plist"];    
    myAnimalDictionary = [[NSMutableDictionary alloc] initWithContentsOfFile:path];
    // I set a breakpoint here in XCode.
}

I dragged myAnimals.plist (which looks like the below) into my supporting files folder for my application.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
    <string>elephant</string>
    <string>monkey</string>
    <string>cat</string>
</array>
</plist>

However, when I reach the breakpoint (as listed in my comment), I see that myAnimalDictionary is nil. Why?

Perhaps it's because you have an array in your .plist but you're trying to instantiate a mutable dictionary instance.
