Hello, When working with Strings which are known to be ASCII, I tend to use the UTF16View for the performance of random access. I would also like to have the convenience of indexing with Int:
let barcode = "M1XXXXXXXXX/CLEMENT EELT9QBQGVAAMSEZY1353 244 21D 531 10A1311446838” let name = barcode.utf16[2..<22] let pnrCode = barcode.utf16[23..<30] let seatNo = barcode.utf16[47..<51] let fromCity = barcode.utf16[30..<33] let toCity = barcode.utf16[33..<36] let carrier = barcode.utf16[36..<39] let flightNumber = barcode.utf16[39..<44] let day = barcode.utf16[44..<47] I define my own subscript in an extension to UTF16View but I think this should go in the Standard Library. Any thoughts? David. _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
