Swift Knowledge Base updates for Swift 4.2
Now that I'm back from my summer vacation, I've updated the Swift Knowledge Base with key examples from Swift 4.2 to make everything easier to find. More updates will come shortly after Swift 4.2 ships as final, but the list below is a good starting point:
New articles:
- How to list all cases in an enum using CaseIterable
- How to add warnings and errors to your code using #warning and #error
- How to handle unknown properties and methods using @dynamicMemberLookup
- How to get a random element from an array using randomElement()
- How to create hash values from objects using Hasher
- Checking all array elements match a condition: allSatisfy()
- Removing matching elements from a collection: removeAll(where:)
- How to toggle a boolean value
Updated articles:
- How to randomize the order of an array: shuffle() and shuffled()
- How to generate a random number
- How to conform to the Hashable protocol
With those new articles, the Swift Knowledge Base now contains 600 tips and examples for Swift developers, all constantly being updated as Swift evolves.
