DTRichTextEditor 1.6.11

I had moved DTRichTextEditor to be Open Source because I wanted bright individuals to be able to contribute to this complex component. I had hatched the plan to ask people who are using the component commercially to set a bounty for fixed issues. This is the second release where a bounty was successfully captured.

Radar: Xcode framework for wrong platform

It took me almost an entire day to figure out that the following issue is caused by some indeterministic behavior of Xcode. As a developer, you expect to see the same results if you use the same parameters (i.e. “deterministic”), but this is a situation that sometimes succeeds, sometimes doesn’t.

In DTFoundation I have two targets that produce a DTFoundation.framework, for iOS and OS X respectively. Now the problems seems to be that since I set both to define a module “DTFoundation”, Xcode randomly gets confused during building an iOS app and sometimes might try to build the OS X framework for iOS.

This was filed as rdar://22008701 and on Open Radar. From the looks of things Rob Rix has filed bug report rdar://20490378 that appears to be describing the same issue. If you disable implicit dependency finding in the scheme, the problem also goes away.

Monetizing Your Apps with Subscriptions

On mDevCamp 2015 Prague I gave a talk on auto-renewable subscriptions. One month earlier, at WWDC and the time leading up to it, I had learned a great deal about this subject and so I worked my experiences into a concise talk so that you will have an easier time implementing subscriptions into your apps.

This is a big update for DTCoreText, maybe even deserving of a minor version bump. It aggregates fixes and enhancements contributed over more than 4 months. This kind of proves that DTCoreText is alive and getting better all the time.

Philosophy versus App Store Rejection

In May 2015, philosopher William Hooper, contracted me to recreate a notes app that should pay tribute to the iOS 6 style. He saw a market for such an app, because he – and many other users – didn’t like the flat style introduced in iOS 7.

I built the 1.0 version in a couple of weeks and enjoyed the challenge of skinning the UI to give it this retro style. Several thousand people downloaded the free app, and I began to believe William that a certain audience found it quite appealing.

Shortly afterwards we added additional paper styles, additional fonts and a different header bar style for users to select and released it as version 1.1. Unfortunately I had made a stupid programming mistake that would cause the notes database to be deleted from time to time. We removed the 1.1.0 version from sale while working on a fix.

When we submitted the 1.1.1 version containing the data loss hotfix version, the troubles began: Apple started to reject the app. After a month back and forth with the app review team, William published the following on his philosophy blog and asked me to share it with my readers.
