The Swiper is the last rapid before reaching the Locust. A rocky approach to the rapid leads to the bottom drop which is a tight pinch between two boulders as the creek makes a tight turn to the left.
You want to angle toward the right boulder, getting your bow up on it a bit to avoid being swiped. If you make the turn too soon and don't ride up on the right rock, you are likely to be on edge and will find yourself being swiped, which isn't great especially if you flip and find the rock in the pool below with your head.
