Key point in Do List 100 v2.0 Brings Due Dates, Auto-Progress and Full iPad & Mac Support

Hi everybody. We have created this app around two months and this is third version with fixed bugs. Now it is amazing app that synchronization your tasks throughs iPhone iPad Mac via iCloud with no Sign In! And in pocket you will already have a useful notes. It was a huge code work. Hours and hours. Such a pleasure. What I want to note here for you fellas, we were going from these scheme: What's really happening The self-overwrite loop User edits subtask title ↓ onChange fires → scheduleSave() → debounce 1s ↓ ...debounce fires → DataManager.save() writes todos.json to iCloud ↓ NSMetadataQuery detects file change on disk ↓ ↑ └── todosChanged() ───────┘ ↓ taskManager.loadTodos() ↓ self.todos = loadedTodos ← 💥 replaces entire array mid-edit The core problem is that NSMetadataQuery watches the file at the OS level. It has no concept of who made the change — your own app writing the file looks identical to another device syncing a change over iCloud. So every save you make triggers a reload that cancels whatever the user is currently doing. Why subtask titles are worst affected A TextField bound to $subtask.title is live — it reflects the array value character by character. The moment self.todos = loadedTodos runs, SwiftUI throws away the in-memory array and rebuilds from the freshly decoded JSON. If the save hasn't happened yet (debounce still counting down), the loaded file has the old title, and the field visually snaps back. Progress sliders have the same issue but it's less noticeable because a slider value is a Double — the snap-back is a jump rather than disappearing characters. Why it only shows up on real devices The simulator runs everything on the same Mac so iCloud writes are near-instant and the race window is tiny. On a real device the file system is slower and iCloud sync adds latency, making the timing gap between "user is editing" and "reload fires" much more visible.
