  The finite reorient-time of swimmers leads to a finite run length $\ell$ and
the kinetic accumulation boundary layer on the microscopic length scale
$\delta$ on a non-penetrating wall. That boundary layer is the microscopic
origin of the swim pressure, and is impacted by the geometry of the boundary
[Yan \& Brady, \textit{J. Fluid. Mech.}, 2015, \textbf{785}, R1]. In this work
we extend the analysis to analytically solve the boundary layer on an
arbitrary-shaped body distorted by the local mean curvature. The solution gives
the swim pressure distribution and the total force (torque) on an arbitrarily
shaped body immersed in swimmers, with a general scaling of the curvature
effect $\Pi^{swim}\sim\lambda\delta^2/L$.
