Pipeline

Reverse function application with optional chaining support.

Quick Look

let attributedString = fileURLString
    |> URL.init(fileURLWithPath:)
    |> { try! Data(contentsOf: $0) }
    ?> UIImage.init(data:)
    ?> NSTextAttachment.init(image:)
    ?> NSAttributedString.init(attachment:)

is equivalent to:

if let image = UIImage(data: try! Data(contentsOf: URL(fileURLWithPath: fileURLString))),
    let attachment = NSTextAttachment(image: image) {
    let attributedString = NSAttributedString(attachment: attachment)
    // use attributedString here
}
