Tool for avoiding using the URL(string:) initializer with optional result, instead introducing a compile time URL validity check. Note, this does not check for website availability, but if the URL is formatted correctly.
The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.
Once you have your Swift package set up, adding SafeURL as a dependency is as easy as adding it to the dependencies value of your Package.swift.
dependencies: [
.package(url: "https://github.com/baguio/SwiftSafeURL")
],
targets: [
.target(
name: "<MyTargetName>",
dependencies: ["SafeURL"],
plugins: ["SafeURLPlugin"]
),
]// This will compile
let validUrl = URL(safeString: "https://example.tld")
// This won't
let invalidUrl = URL(safeString: "https://example./tld")SafeURL requires its parameter to be a single simple string literal
If a file contains the comment // safeurl:warn, invalid URLs in this file will be compiled and will show a warning instead of an error. Note that this is not recommended, as this will still cause a force-stop on runtime.
