Turns out that the NSSecureCoding content was the URL, but in hexadecimal. Here's how I'm converting it to String:
let urlHex = dict.debugDescription
.replacingOccurrences(of: "Optional(", with: "")
.replacingOccurrences(of: ")", with: "")
.replacingOccurrences(of: "<", with: "")
.replacingOccurrences(of: ">", with: "")
.replacingOccurrences(of: " ", with: "")
guard let urlHexData = Data(fromHexEncodedString: urlHex) else { return }
guard let url = String(data: urlHexData, encoding: .utf8) else { return }
extension Data {
// From http://stackoverflow.com/a/40278391
init?(fromHexEncodedString string: String) {
func decodeNibble(u: UInt16) -> UInt8? {
switch(u) {
case 0x30 ... 0x39:
return UInt8(u - 0x30)
case 0x41 ... 0x46:
return UInt8(u - 0x41 + 10)
case 0x61 ... 0x66:
return UInt8(u - 0x61 + 10)
default:
return nil
}
}
self.init(capacity: string.utf16.count/2)
var even = true
var byte: UInt8 = 0
for c in string.utf16 {
guard let val = decodeNibble(u: c) else { return nil }
if even {
byte = val << 4
} else {
byte += val
self.append(byte)
}
even = !even
}
guard even else { return nil }
}
}
