Build 4-view app using CloudKit (data-driven UX + pixel perfect UI)

Freelance Project: Build 4-view app using CloudKit (data-driven UX + pixel perfect UI) * A Keynote deck will be shared with vetted freelancers that includes high-res mockups and detailed examples of UX flow (including animations) * Use IBAnimatable for animations (this facilitates customization later on, see [login to view URL]) * I will provide you with access to the CloudKit container that you can code against. I will populate the database with sample data and any assets you may need. * Note: You will be expected to use your own developer account to build and test the app during development. Once the final project is delivered & accepted, I will modify the code so that the prod app uses my developer account & resources (not yours). The deliverable is a complete Xcode 9 (64-bit) project; here are the general requirements for the project: * iOS 11 app (must be iPhone X compatible) * Swift 4 * Data security is a priority from start to finish: * All local files created/owned by app must use Complete Protection (NSFileProtectionComplete) data protection class. * Keys must be stored in Secure Enclave whenever possible (if iPhone hardware is too old, then store securely on device) * Require passcode, Touch ID, or Face ID any time user a) re-starts the app, b) after the phone is locked then unlocked, and/or c) after 15 min of continuously running in the background, whichever comes first To be considered complete, the app must: 1. Perform the actions demonstrated in the Keynote deck 2. UI must look like the high-res mockups in the Keynote deck 3. Not crash (goes without saying) 4. *and*: 1. Filtering/Business logic code must be segregated from Views (subclass UIManagedDocument, see [login to view URL]) * Use auto-layout * Use IBAnimatable for animations (this facilitates customization later on, see [login to view URL]) * Instantiate and maintain a local cache of CK records to enable online *and* offline use (see [login to view URL]) * Use Operation Groups to logically bundle data operations * Include unit and integration tests. At a minimum, include test coverage for: - [ ] DB: operations and operation groups - [ ] Data version resolution (see [login to view URL]) - [ ] Changes in iCloud availability (see [login to view URL]) * Adhere to requirements for submission to the App Store (with minor exceptions such as the need to tweak credentials/profiles) * Adhere to one of the following style guides (you choose which one you prefer): Ray Wenderlich ([login to view URL]) or LinkedIn ([login to view URL]) * Be fully-documented using Markup for Swift/Markdown such that Quick Help documentation is available. This means that every function/method must include values for description, parameters, returns, and throws (as appropriate).
