Does this count a resiting A levels ?

If I fail my AS exams then quit the course and a year later take the A level exam for the course I quitted would that count as retaking the a level despite being the first time taking the actual A level exam?

Not retaking, no. But it might be seen by some unis as having taken three years to complete a two-year course.

Are you in Wales or Northern Ireland, where A level qualifications are the result of AS exams (contributing 40% of the final grade) and A2 exams (contributing 60% of the final grade)?

Or are you in England, where AS qualifications are entirely separate from A level qualifications? (In England students don't take formal AS exams at the end of year 12 for their A level subjects. They take internal end-of-year exams instead.)

I am in England
