Definition
Write $(\infty,0)Cat$ for the category ∞Grpd of $\infty$groupoids regarded as an (∞,1)category.
Let $S$ be a simplicial set (which in particular may be a quasicategory).
An $(\infty,1)$presheaf on $S$ is an (∞,1)functor
$F : S^{op} \to (\infty,0)Cat
\,.$
The (∞,1)category of $(\infty,1)$presheaves is the corresponding (∞,1)category of (∞,1)functors
$PSh(S) := Fun(S^{op}, (\infty,0)Cat)
\,.$
