Sweet income generated by a tech giant? (5,8)
I believe the answer is:
apple turnover
'sweet' is the definition.
(type of sweet pastry)
'generated by a tech giant?' is the wordplay.
'generated' becomes 'turnover' (I can't justify this - if you can you should believe this answer much more).
'by' says to put letters next to each other.
'a tech giant?' becomes 'apple' (I've seen this in another clue).
'turnover' put after 'apple' is 'APPLE TURNOVER'.
'income' is the link.
This may not be right. It may belong to another bit of the clue.
(Another definition for apple turnover that I've seen is " afters".)
