An Xcode playground that demonstrates the new features introduced in Swift 5.3.

What’s new in Swift 5.3?

This is an Xcode playground that demonstrates the new features introduced in Swift 5.3:

Multi-pattern catch clauses
Multiple trailing closures
Synthesized Comparable conformance for enums
self is no longer required in many places
Type-Based Program Entry Points
where clauses on contextually generic declarations
Enum cases as protocol witnesses
Refined didSet Semantics
A new Float16 type
Swift Package Manager gains binary dependencies, resources, and more

This is designed to complement my existing article What’s New in Swift 5.3. You might also want to read What’s New in Swift 5.2 and What’s New in Swift 5.1. Alternatively, I have a whole website dedicated to tracking what's new in Swift – you should check it out at https://www.whatsnewinswift.com.
