SwiftTime

SwiftUI menu bar app for comparing local time with a small set of world clocks and pinning exact hours for planning.

Caution

This app was "vibe coded" with Codex/GPT-5.4. Do not use it as is, do not trust this code!

Notes

• This version is intentionally minimal: one Swift source file plus this README.
• The menu bar icon is a clock symbol only.
• The world clock list is hardcoded in source for now. Edit SwiftTime.swift to change the tracked locations.
• The app uses a single planning flow: use Set Hour on local time or any world clock row to pin the planner to an exact hour in that timezone.
• The per-location hour picker is hour-granularity by design. It sets minutes and seconds to 00.
• Germany uses Europe/Berlin rather than a fixed CET offset so daylight saving transitions are handled correctly.

Build

git clone <your-repo-url>
cd SwiftTime
swiftc -parse-as-library -framework SwiftUI -framework AppKit -o SwiftTime SwiftTime.swift

Run

./SwiftTime

The app lives in the macOS menu bar and updates continuously while open.

Launch At Startup

Because this project is a bare executable rather than a bundled .app, the simplest startup option is a per-user launchd agent managed by the included script.

1. Build the binary:

swiftc -parse-as-library -framework SwiftUI -framework AppKit -o SwiftTime SwiftTime.swift

2. Add it to startup:

./startup.sh add

3. If you rebuild the binary later, reload the login item:

./startup.sh update

4. To remove it from startup:

./startup.sh remove

The script writes ~/Library/LaunchAgents/com.kastner.swifttime.plist pointing at the SwiftTime binary in this checkout. If you move the checkout, run ./startup.sh update.
