1,935 Pointswhat is wrong with my "for in" loop?
it says that i am not using a format specifier. Any suggestions will be much appreciated.
NSArray *drinks = [NSArray arrayWithObjects: @"juice",@"water",@"coffee", nil];
for (NSNumber *snacks in drinks){
NSLog (@"juice");
NSLog (@"water");
NSLog (@"coffee");
}

The first problem is that it is labeled as an NSNumber, but the list is full of NSStrings. The type the list is iterating over should mirror the type in the list. Next, the NSLog statement is being logged explicitly but it should be implicitly logged.
NSArray *drinks = [NSArray arrayWithObjects: @"juice",@"water",@"coffee", nil];
for (NSString *snack in drinks) {
NSLog(@"%@", drink); // only writing the statement once, but iterates through the list until it comes to nil.
}
