UINavigationBar on iOS 11

NOTE This note is written based on Xcode version 9.0 beta 6 (9M214v) and its simulator binary.

iOS 11 changes UINavigationBar a lot, not just only for its large title, but also the internal view hierarchy and lay outing views are changed. This is a small note about UINavigationBar behavior on iOS 11, mainly focusing on migrating the application to iOS 11.

Lay outing views

UINavigationBar has been using manual lay outing until iOS 10, so all its content views like titleView has been directly child view of the UINavigationBar. However, since iOS 11, it is using auto layout with bunch of layout guides to lay out its content views in its own internal container view, _UINavigationBarContentView.

Create PDF files from Markdown sources in OSX

When [Markdown][markdown] appeared more than 10 years ago, it aimed to make it easier to express ideas in an easy-to-write plain text format. It offers a simple syntax that takes the writer focus away from the formatting, thus giving her time to focus on the actual content.

The market abunds of editors to be used for help with markdown. After a few attempts, I settled to Sublime and its browser preview plugin, which work great for me and have a small memory footprint to accomplish that. To pass the results around to other people, less technical, a markdown file and a bunch of images is not the best approach, so converting it to a more robust format like PDF seems like a much better choice.

[Pandoc][pandoc] is the swiss-army knife of converting documents between various formats. While being able to deal with heavy-weight formats like docx and epub, we will need it for the more lightweight markdown. To be able to generate PDF files, we need LaTeX. On OSX, the s
