Instance Property インスタンスプロパティ

lines

The URL’s resource data, as an asynchronous sequence of lines of text.

Declaration 宣言

var lines: AsyncLineSequence<URL.AsyncBytes> { get }

Discussion 議論

Use this property with Swift’s for-await-in syntax, to read the contents of a URL line-by-line, like this:


guard let url = URL(string: "https://www.example.com") else {
    return
}
do {
    // Read each line of the data as it becomes available.
    for try await line in url.lines
    {
        // Do something with line.
    }
} catch {
     print ("Error: \(error)")
}

To wait for the entire resource to load, use the URLSession method data(from:delegate:) with the await keyword. URLSession also offers methods to upload data to a URL endpoint and download a URL’s contents to a file.
