NonEmptySwift
Swift Standard Library/Foundation APIs with compile-time guarantee of non-empty collections. Based on pointfreeco/swift-non-empty.
Usage
String.components(separatedBy:)
The Foundation method components(separatedBy:) is actually guaranteed to not be empty, because even if you call it on an empty String, you get [""] as a result. And if you pass a separator to it that doesn’t exist on the String, you’ll get back the string itself as the only element in the Array. This library makes that guarantee explicit by returning the result wrapped in NonEmpty.
var text: String = "Ginevra,Harry,Hermione,Ronald"
var nonEmptyComponents: NonEmpty<[String]> = text.components(separatedBy: ",")
// => ["Ginevra", "Harry", "Hermione", "Ronald"]
