lines
The URL’s resource data, as an asynchronous sequence of lines of text.
Declaration
var lines: AsyncLineSequence<URL.AsyncBytes> { get }Discussion
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.
