Clean-Slate Design: Route & Navigation State

What the app actually needs

The app has two modes for a route: editing and navigating. The current design splits this across CurrentRouteState (route definition + editing) and NavigateToState (live navigation engine), with NavigationInfo as a per-tick geometry snapshot. The complexity comes from duplicated fields, manual sync, and identity data mixed into geometry structs.

Current Structure

NavigationInfo (value type)

A struct on NavigateToState.currentInfo. Rebuilt on every GPS tick by BuildNavigationInfo during active navigation. Set to nil on stop.

Fields:

• nextWaypoint: Waypoint — the waypoint being navigated toward

iOS: Apostrophes in User-Facing Strings

Recommendation

Use straight apostrophes (', U+0027) in Swift source code for user-facing strings.

Why

• iOS renders straight apostrophes as typographic/curly ones automatically when displayed in Text, UILabel, etc.
• The system font (SF Pro) handles this via OpenType ligature substitution.

CurrentRouteState: points vs waypoints Assessment

Summary

DrawingPoint (persisted source of truth) and Waypoint (derived view-model) serve distinct roles. Merging them is not recommended.

How They Relate

CurrentRouteState.points is [DrawingPoint]. Whenever points is set, waypoints is automatically rebuilt via a didSet:
