Things

A notepad for what's on your mind.

A "thing" has a name, a date, optional tags (people / places / feelings), and the ability to star/favorite what matters. Swipe-left a card to mark it completed. Completed cards show up on their own searchable page.

Stack

• SwiftUI, iOS 17+
• Single-target Xcode project, no third-party dependencies
• UserDefaults JSON persistence (Persistence.swift)
• App icon and project.pbxproj are generated by scripts (see below) so they stay reproducible

Run

open Things.xcodeproj

…then ⌘R against any iPhone simulator.

Regenerating

The Xcode project file and the app icon are both generated:

python3 scripts/generate_xcodeproj.py    # rewrites Things.xcodeproj/project.pbxproj
python3 scripts/generate_icons.py        # rewrites Assets.xcassets/AppIcon.appiconset/icon-1024.png

Re-run generate_xcodeproj.py after adding or removing a Swift file — it auto-discovers everything under Things/.
