Add support for manipulating specific bits within an integer by treating it like an array of Bool values

UInt+Bits.swift

// Source: https://www.douggregor.net/posts/swift-for-cxx-practitioners-extensions/

extension UInt32 {
	subscript(index: Int) -> Bool {
		get {
			(self & UInt32(1) << index) != 0
		}
		set {
			let mask = UInt32(1) << index
			self = (self & ~mask) | (newValue ? mask : 0)
		}
	}
}

// Usage
var flags: UInt32 = 0b1001
flags[2] = true  // set bit #2
flags[0] = false // clear bit #0
