What’s new in Swift 5.1?
This is an Xcode playground that demonstrates the new features introduced in Swift 5.1:
- Warnings for ambiguous
- Matching optional enums against non-optionals
- Ordered collection diffing
- Creating uninitialized arrays
This is designed to complement my existing article What’s New in Swift 5.1. You might also want to read What’s New in Swift 5.0 and What’s New in Swift 4.2. Alternatively, I have a whole website dedicated to tracking what's new in Swift – you should check it out at https://www.whatsnewinswift.com.
Note: Until a version of Xcode ships with Swift 5.1, you should download the latest Swift trunk development snapshot and activate it inside your current Xcode version.
