Four months ago, I reported a scenario where LLVM would crash with a segmentation fault. A later Xcode version fixed the LLVM crash, but now the crash would occur during runtime. This surprised me: Why would it be valid syntax accepted by the compiler, yet crash during execution?
Sheet dismissal bug when window is hidden
Our customer found the following issue. In our apps we are showing some sheets for displaying progress to the user (downloading a bunch of images for example). I was not aware that if you ALT + CLICK in macOS ouside your window it gets hidden. When you do this and dismiss the sheet meanwhile an empty sheet remains on top of your window.

Use Legacy Swift Language Version
There is a bug in Xcode 8.2 that – after upgrading to this version – it is no longer able to build your project. The build error message is:
Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift.
We saw this in projects where we are not using any legacy Swift, i.e. everything is Swift 3. Also there is a project-wide setting to NOT use legacy Swift. The new bug seems to ignore the project-setting.
POEditorAPI 1.1.0
In the month since the initial release of the POEditor.com API and command line utility, I did some refinements which become necessary to support ongoing development projects. Generally speaking you should use the poet tool without parameters to refresh your strings files.
Introducing the POEditor.com API and Tool
If you want to be successful in international markets you need to localize your app in as many languages as you can. For iWoman we use POEditor.com. As the number of localization grows it becomes increasingly time-consuming to update all localizations in your Xcode project, let alone deal with plurals which are not supported in the XLIFF format.
Today I am showing off, how I got the update process to be a matter of seconds. I achieved this by writing a POEditor.com API and building a command line tool – I call POET (for POEditor Tool) which greatly simplifies the update process.
DTCoreText 1.6.19
Hot on the heels of the previous release for DTCoreText this update hot-fixes several issues which were introduced in the previous release.
DTCoreText 1.6.18
Since the prior release of DTCoreText, 9 months ago, a few issues became apparent with Xcode 8. Some people contributed cool stuff like support for use in app extensions as well as tvOS support.
Bug: NSCollectionView Move Sections Crash
We are so foolhardy that we are using NSCollectionView in an internal project that gets widely used by an enterprise client of ours. We found this latest crashing bug while updating the application for macOS 10.12 wich is where the issue first appeared.
The only workaround at this time is to remove animation via animator() and replace it with a reloadData. Thus we vote NSCollectionView for worst Apple API on macOS.

DTFoundation 1.7.11
With the prior update to DTFoundation having been 5 months ago, there were two main areas where some tweaks were necessary: support for tvOS and fixing a build error on Xcode 8.
LLVM Crash
I found this LLVM compiler crash when updating a project for building with Xcode 8. At first I thought it had to do with #if DEBUG because the crash didn’t occur when I removed the conditional compiling block. But further experimentation showed that it is a specific line in this block that is causing the issue.
