I want to get UDID of iOS device programmatically. I am using the following code to get UDID of iOS device.
NSUUID *uuid = [NSUUID UUID];
NSString *uuidString = uuid.UUIDString;
NSString* Identifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; // IOS 6+ NSLog(@"output is : %@", Identifier);
let Identifier: String = UIDevice.currentDevice().identifierForVendor().UUIDString() NSLog("output is : %@", Identifier)
Apple is apparently starting to remove access to the UDID (Unique Device IDentifier) in iOS5. In any event, the best you can now do for identification purposes is to use a UUID (Universally Unique IDentifier). This has to be on a per-app basis. That is, there is no way to identify the device any longer, but you can identify an app on a device.As long as the user doesn’t completely delete the app, then this identifier will persist between app launches, and at least let you identify the same user using a particular app on a device. Unfortunately, if the user completely deletes and then reinstalls the app then the ID will change, but this is the best anyone can do going forward.
