New from Dragon Forged Software, Slender (US$9.99, currently on sale for $4.99) is a narrowly-focused utility that will either be exactly the tool you're looking for or one you can safely skip. It helps you non-destructively optimize Xcode projects by allowing you to view, evaluate, and adjust development assets.
For example, you can scan multi-resolution image collections. Slender detects when you might be missing a @2x asset or have used an incorrect dimension. That's particularly handy when you're working on large projects and may find it hard to otherwise audit your images by hand.
Slender also matches assets to source code, so you can automatically remove unused asset items to help save space in your shipping bun
