In QGIS 3.2 I have a viewshed raster and a shapefile with point features
I'd like to select the points that intersect the visible areas of my viewshed.
Is there a way to extract a vector of my visible areas so that I can then Select by Location?

One option would be to extract the pixel value at each point and then perform a select expression to identify points in viewshed, see q/a link below:
Another option would be to convert raster to polygon using the Polygonize tool and perform select by location:
