This app was originally written for iOS3. That's before GCD & ARC was available, which were released for iOS4 & iOS5 respectively. That's also before the first Retina display of the iPhone 4 or much newer iOS features like Dark Mode or the Dynamic Island. Let alone Swift or SwiftUI.

@martinstolz and me wrote it together as a side project to learn iOS development in 2010. We maintained and updated it for 10 years until we finally took it out of the AppStore in 2020.

Disclaimer: Don't think of the code here as an exemplary app architecture, but instead as a small window into the history of iOS development.

This repository contains the source code of two original versions of the app; from 2020 and 2012. Both still compile and run on today's Xcode 15 (as of 2024).

• HIGHLIGHTS.md lists some highlights in the source code and the choices we made, while making the App.
• CHANGELOG.md shows a full list of changes between these two versions.

The most recently released version. A fairly modern iOS app; at least in comparison to below version 1.5.

• It has an iOS 7 redesign, iPhone X support, dark mode and many additional features.
• Persistence is handled by a Realm database.
• LOC*: roughly ~9000 lines; notably not that much more than v1.5, even though it has many more features.
• Open source dependencies:
  • ZoomInteractiveTransition from https://github.com/DenTelezhkin/ZoomInteractiveTransition

Pretty close to the original version from 2010. This is quite historic.

• This version still uses manual reference counting; e.g. see the 177 manual retain/release calls.
• Contains @2x assets - the iPhone 4 came out on 06/2010.
• The persistence is simply based on NSUserDefaults.
• LOC*: roughly ~7500 lines.
• Open source dependencies:
  • DDAnnotationView from https://github.com/digdog/
  • UIColor+ColorWithHex from https://github.com/pixeldock/PDUtils
  • UIView+position from https://github.com/tylerneylon/moriarty

* LOC measured in the /Classes directory by calling: find . -name '*.m' | xargs wc -l | sort minus any externally pulled in dependencies.
