In Swift 4, strings have been totally re-imagined to put speed and simplicity at the forefront. The Swift 4 offers “implementation that retains Unicode correctness and adds support for creating, using and managing substrings.” Part of this is a new literal for multi-line strings so our developers now have the capability to declare a triple-quote (i.e. “””) for paragraphs and even longer text threads. You can easily and quickly rearrange items in an array using the new swapAt function. The helpful package manager includes all Swift 4 APIs sandboxed on macOS.
The Swift4 prevents network access and file system modification, to help mitigate the effect of maliciously crafted manifests. The new package API allows packages to specify novel settings and give the authors agency over how they develop.
