What causes lift in aerofoil: Bernouli's principle or Newton's third law?
I think it is erroneous to say that lift is solely produced just because of the Bernoulli's or Newton's law.

Sixty Symbols(A youtube channel) explains the best how a wing actually produces lift.


                
            

Instead of explaining I thought this video might help you more than my explanation. And also look at "Incorrect Lift theory" by NASA
