stillwaitin-app

The still waitin app source code - active in the App Store from 2010-2020.

App Description:

Keep track of your cash financials. Never forget about money that you lent to or got from friends, family, colleagues or customers. No matter the amount. Get a push reminder at the day & time of your choice or send out a formatted email about open debts to your contacts, so they don't forget either.

Background

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. So don't mistake it as an exemplary app architecture, but instead as a small window into the history of iOS development.

We maintained and updated it for 10 years until we finally took it out of the AppStore in 2020.

Also see HIGHLIGHTS.md, which highlights a few spots in the source code and the choices we made, while making the App.

Source code

We are open sourcing the source code of two versions of the app here. Both still compile and run on today's Xcode 15:

Version 2.4 (from 2020)

• The most recent released version. A fairly modern iOS app in comparison to 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

Version 1.5 (from 2012)

• This version still uses manual reference counting.
  • 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.

Changelog

See the CHANGELOG.md for a full list of changes between these two versions.
