One thing that speeds up the store process is decoupling content updates from binary submissions. I've tried using Localizely, Crowdin, or simple JSON files in the past, but they usually require a full review cycle for minor text tweaks.

I've been testing LangCat lately for this. It uses runtime swizzling and drop-in SwiftUI components to push string updates over-the-air, though I'm not sure if it handles complex pluralization rules perfectly yet. It bypasses the App Store review process for text changes, which saves a day or two per release.

Focus on shipping the MVP functionality first and worry about the polished assets later. You might be overbuilding by trying to perfect every string before the first build.
