Design an iOS keyboard for technical users (developers, sysadmins) that makes typing code and special symbols fast. The keyboard should show a customizable top strip that smartly surfaces symbols based on context (e.g., brackets when editing code, a pipe when writing command lines). Let users create shortcuts that expand into reusable code snippets and keep these in sync across devices with iCloud. Add trackpad‑like gesture cursor control for precise selection, and include a privacy‑focused clipboard history where items are stored securely. Provide a companion container app for managing layouts, snippets, and themes; build it with SwiftUI and organize the app using an MVC approach.
