I believe the answer is:

veer

I'm a little stuck... Click here to teach me more about this clue!

'swing round' is the definition.
(thesaurus)

'ever varying direction' is the wordplay.
'ever' can be anagrammed to 'VEER'.
But, I am unsure how the anagram is indicated.

'in' is the link.

Can you help me to learn more?

(Other definitions for veer that I've seen before include "Change direction abruptly" , "Sudden direction change" , "Suddenly change direction" , "Change direction sharply" , "Swing around" .)

I've seen this clue in the Evening Standard.
