Difference between objective-C Enum and typedef

Enum and typedef, two examples are shown in the two sections respectively, as shown below:

Enum direction {north, south, east, west };

Typedef Enum {north, south, east, west} direction;

I can't help wondering what are the differences between the two. I checked them carefully and found that:

Similar,

Same: both declare an enumeration type.

Difference: when using this enumeration type to define variables, the syntax is different, for example:

1 Enum direction {north, south, east, west };
2 Enum direction facing = North;

1 typedef Enum {north, south, east, west} direction;
2 direction facing = North;
