# init(_:strategy:) Creates a URL instance by parsing the provided input in accordance with a parse strategy. ``` init(_ value: T.ParseInput, strategy: T) throws where T : ParseStrategy, T.ParseOutput == URL ``` ## Parameters `value` The value to parse, as the input type accepted by `strategy`. For [`URL.ParseStrategy`](/documentation/Foundation/URL/ParseStrategy), this is . `strategy` A parse strategy to apply when parsing `value`. ## Discussion The following example parses a URL string, with a custom strategy that provides a default value for the port component if the source string doesn’t specify one. ```swift let urlString = "https://internal.example.com/path/to/endpoint?key=value" let url = try? URL(urlString, strategy: .url .port(.defaultValue(8080))) // https://internal.example.com:8080/path/to/endpoint?key=value ``` --- Copyright © 2026 Apple Inc.
