What is special about 2^32$2^{32}/ϕ\varphi$ in cryptography?

In the Tiny Encryption Algorithm:

Different multiples of a magic constant are used to prevent simple attacks based on the symmetry of the rounds. The magic constant, 2654435769 or 9E3779B916 is chosen to be 23^2/ϕ$2^{32}/ \phi$, where ϕ is the golden ratio.

Which properties does 2^32/ϕ$2^{32}/ \phi$ have that makes it useful in this context?
