Objective-C implicit conversion loses integer precision 'NSUInteger' (aka 'unsigned long') to 'int'
...as unsigned long, and
unsigned long is a 64-bit unsigned integer.
int is a 32-bit integer.
So int is a "smaller" datatype than NSUInteger, therefore the compiler warning.
See also NSUInteger in the "Foundation Data Types Reference":
When building 32-bit applications, NSUInteger is a 32-bit un...
