I need to get NSData
from vendorIdentifier
without converting to NSString
, clear bytes.
How to convert NSUUID
using getUUIDBytes:
to NSData
?

Use this to get the vendorIdentifier
as Data
(Swift 4):
var uuidBytes = UIDevice.current.identifierForVendor!.uuid
let uuidData = NSData(bytes: &uuidBytes, length: 16) as Data
Keep in mind to guard against UIDevice.current.identifierForVendor
being nil as the documentation says.
Original answer (Swift 2 Version):
var uuidBytes: [UInt8] = [UInt8](count: 16, repeatedValue: 0)
UIDevice.currentDevice().identifierForVendor!.getUUIDBytes(&uuidBytes)
let uuidData = NSData(bytes: &uuidBytes, length: 16)
Swift 3 Version:
let vendorId = UIDevice.current.identifierForVendor!
let uuidBytes = Mirror(reflecting: vendorId.uuid).children.map { $0.1 as! UInt8 }
let data = Data(bytes: uuidBytes)
