wtf is realm-sharedtasks?

Realm SharedTasks is a tutorial project that teaches you how to build an iOS app where multiple users can share to-do lists with each other in real time. Instead of tasks living in a single central database that everyone writes to, each user keeps their own private task list and can selectively grant other people permission to view or sync specific items. The end result is a collaborative task app where you control who sees what. The project walks you through setting up a new iPhone app from scratch using Swift and Xcode, Apple's standard development tools. It relies on two key components: RealmSwift, which handles saving and syncing data across devices, and RealmLoginKit, a pre-built login screen that handles user accounts with almost no coding required. You also run a local server called the Realm Object Server on your Mac, which acts as the hub that authenticates users and coordinates data syncing between them. This tutorial is designed for iOS developers who want to learn how the Realm Mobile Platform handles multi-user apps and fine-grained permissions. The concrete example is a shared tasks app: you log in, create your own private to-do list, and then share specific tasks or lists with other users by adjusting permissions. The tutorial pays special attention to how permissions work in practice, since that is what makes selective sharing possible without dumping everyone's data into one shared pool. One notable design choice is the architecture itself. Rather than using a single shared database that all users write to together, the app gives each user their own private Realm file and then manipulates permissions to let specific people access specific data. This peer-to-peer sharing approach means users have more control over their own data, and the tutorial walks through the mechanics of making that work, including a Person model that maps human-readable names to the system's internal user IDs so you can find people without memorizing long identifiers. The tutorial also provides a fully completed version of the app for download, since the finished source code is too long to type out by hand.
