    Parameters

    regex

    A regular expression to convert to use a strongly-typed capture list.

    outputType

    The capture structure to use.

    You can use this initializer to convert a regular expression with a dynamic capture list to one with a strongly-typed capture list. If the type you provide as outputType doesn’t match the capture structure of regex, the initializer returns nil.

    let dynamicRegex = try Regex("(.+?): (.+)")
if let stronglyTypedRegex = Regex(dynamicRegex, as: (Substring, Substring, Substring).self) {
    print("Converted properly")
}
// Prints "Converted properly"
