How to use a .xcconfig file and a .plist file with SPM

Worth a read for some more context.

Create a Package.xcconfig file

Create the file in the root of the project (where your Package.swift file lives as well), and use the following contents:

/// Package.xcconfig

  - anyobject_protocol
  - array_init
  - attributes
  - block_based_kvo
  - class_delegate_protocol
  - closing_brace
  - closure_body_length
  - closure_end_indentation
  - closure_parameter_position

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.

Making sure AVKit is used

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        
        ...
      
        // Disable the NSLayoutConstraint warnings thast are cluttering

Basic firewall / network router using Gentoo Linux.

After compiling the 4.19.66-gentoo kernel, udev renamed the network interfaces of my home linux Router / Firewall and my iptables setup stopped working due ip-conntrack kernel deprecations. I decided to move over to nftables, the new packet classification framework that replaces the existing {ip,ip6,arp,eb} tables infrastructure.

Even though nftables has been in the Linux kernel since 2014, the documentation is extremely sparse. As such this gist :)

Subjectively, using nftables setting up connections to my machine seems to be more responsive compared to using iptables. Connections seem to be made more quickly and ssh-ing into my machine seems more responsive. There always used to be a bit of a lag when I was using iptables, not anymore.
