Last year Apple began moving Swift and its associated projects from GitHub.com/apple over to GitHub.com/swiftlang, and the reason is becoming clear: you can now use GitHub Sponsors to support the project with a regular monthly donation, getting various rewards in return.
There are a number of tiers on offer right now, but this might change over time – keep an eye on the project for updates.
The launch tiers are:

$5 a month: Your name is added to a @discardableResult contributor list. Might be used. Might not.
$10 a month: Your name and email address are displayed in Xcode's crash dialog. You're welcome.
$20 a month: You get to use C-style for loops again – admit it, you missed them.
$30 a month: Receive one (1) tub of Craig Federighi’s personal hair gel. Warning: may result in sudden confidence, vertical hair lift, and involuntary keynotes.
$50 a month: You gain access to a special version of LLDB where po works first time. (But only on Tuesdays.)
$100 a month: Includes one automatic rewrite of a Swift expression too big for the compiler to type check. Xcode will automatically split your line into 47 let statements and add a single comment, "There. Happy now?"
$250 a month: Your name is chosen as a Swift reserved word so you can strut around in code reviews like the royalty you are.
$500 a month: Every time you force unwrap an optional, a monk from Apple’s compiler team lights a candle. Your app will probably still crash, but morally you’re in the clear.
$750 a month: Xcode will let you disable WiFi debugging for a device, but only if you ask nicely.
$1000 a month: The compiler will start issuing passive-aggressive warnings. "Oh, you're still using Combine? Brave."
$2000 a month: Your Swift code is no longer subject to ABI stability. You are the ABI now.
$5000 a month: Once per month, Tim ...
