Run shell script on gist

Shells that support process substitution such as bash and zsh allow to run shell script on gist as follows.

# With curl:
bash <(curl -sL ${GIST_URL}) args...

# With wget:

If you work on a Swift project that follows the Model-View-ViewModel (MVVM) architecture or similar, you may want to jump to counterpart in Xcode from your view to your model, and then to your view model. (ie. by using Ctrl+Cmd+Up and Ctrl+Cmd+Down).

You can do this in recent versions of Xcode by setting a configuration default.

From a terminal, just type this command and press Enter:

defaults write com.apple.dt.Xcode IDEAdditionalCounterpartSuffixes -array-add "ViewModel" "View"

Detecting Video Playback inside a WKWebView

Observing video playback inside a black-boxed WKWebView is difficult as you don't have direct access to the video player.

Another complicating matter is that depending on the video, the video might be played using a HTML5 video player, while others might launch the native AVPlayerViewController for playback. While it might be possible to detect HTML5 based playback by injecting custom JavaScript using a WKUserContentController, this is not the approach we will follow in the document as these depend on what HTML5 Video Player is involved and is, as such, not a generic solution.
