What's the difference between UUID, GUID and UDID?

UUID (Universally Unique Identifier): A sequence of 128 bits that can guarantee uniqueness across space and time, defined by [RFC 4122][rfc4122].
GUID (Globally Unique Identifier): Microsoft's implementation of the UUID specification; often used interchangeably with UUID.
UDID _(Unique Device Identifier)): A sequence of 40 hexadecimal characters that uniquely identify an iOS device (the device's Social Security Number, if you will). This value can be retrieved through iTunes, or found using UIDevice -uniqueIdentifier. Derived from hardware details like MAC address.

Is UDID deprecated?

Synopsis

At the top of the file there should be a short introduction and/ or overview that explains what the project is. This description should match descriptions added for package managers (Gemspec, package.json, etc.)

Code Example

Show what the library does as concisely as possible, developers should be able to figure out how your project solves their problem by looking at the code example. Make sure the API you are showing off is obvious, and that your code is short and concise.

	// Create a UIViewPropertyAnimator object. Here's a simple one with a UIKit animation curve:
	let colorChange = UIViewPropertyAnimator(duration: 0.3, curve: .easeIn, animations: { [weak self] in
	self?.view.backgroundColor = UIColor(red: 255.0/255.0, green: 80.0/255.0, blue: 43.0/255.0, alpha: 1.0)
	})

	// There's also support for easy spring-based animations - all you need to set is a damping ratio (a value between 0 and 1). Alternatively, you can create your own curves by adopting the UITimingCurveProvider protocol.
	let alphaChange = UIViewPropertyAnimator(duration: 0.3, dampingRatio: 0.6, animations: { [weak self] in
	self?.circleView.alpha = 0.0
	})
