This codebase is the code that runs alerts and overlays on the Cocoatype Twitch stream, but with several copyrighted elements removed. As such, it will not build out of the box. However, it should still be able to provide sample code for implementing similar effects in a different codebase.
This project has a dependency on my Twitch Chat Swift package.
Yes, it's AppKit. Sorry.
No overview available.
The window that contains every other view. It is a full-screen window that floats over every full-screen Space on your Mac. Other than that, it's nothing special; just a standard window.
No overview available.
Displays notifications when chatters post in my channel. This includes support for Twitch emotes (though animated emotes do not yet animate), as well as chatters' self-selected username colors. There is no support yet for other chat-based addons such as bits or highlighted chat.
Displays a floating overlay showing the screen of a connected iOS device. Mousing over (under?) the overlay causes it to become translucent to show the screen behind the overlay.
AppleScript support allows you to hide, show, or full-screen the overlay. I use this support to add these commands to an Elgato Stream Deck.
This is a work in progress to replace the Streamlabs web-based alerts with a native display, similar to the work done for chat. It is not currently used. Finishing this support requires a server component, which will be open-sourced when it is complete.
This was a celebration for my 100th Twitch follower. Instead of playing the normal follower alert, it played the cannon section of Tchaikovsky's 1812 Overture, complete with visual effects and pulsing overlays. It was pretty awesome.
I don't remember why it's called Project Quicksilver.
The code in here that starts with "OAuth" is useful! The rest isn't! Ignore it!
(The OAuth code is used to get access tokens for the chat support.)
This section used to be the bulk of the project; it uses web views with transparent backgrounds to display Streamlabs widgets. The only remaining web view is alerts; other widgets have been replaced with native counterparts.
There are some environment variables used throughout the codebase. You can set these in the Xcode scheme editor, under Run > Arguments.
ALERT_BOX_URL is a URL to a Streamlabs Alert Box widget. You can get this in the Streamlabs dashboard.
APP_CLIENT_ID is a client ID for a Twitch app. You can get this in the Twitch developer console.
APP_CLIENT_SECRET is a client secret for a Twitch app. You can get this in the Twitch developer console.
CHAT_REFRESH_TOKEN is a refresh token for your Twitch user account with the chat:read scope. The easiest way to get this is with the Twitch CLI: twitch token -u -s chat:read
These are device frames displayed around the video overlays when using the full screen mode. They are modified versions of Apple's device frames (though likely for devices no longer available).
overture.m4a is a recording of the cannons section of the 1812 Overture for Project Quicksilver.
These are alert sounds played when you gain a new follower or subscriber.
