As I understand it now can not get apple id in iOS 7.
iOS 8 has many edits to work with iCloud and adding iCloudKit. Will I be able to get Apple id from API and use it, for example, for registration in own server?
No, you cannot get the user's Apple ID.
What you can do with CloudKit is get an opaque user record ID. This object will be the same for the user for your app on all of their devices, but it will be different for other apps or other users. You can save that on your server and use it as something like a "log in with CloudKit" feature. This was described in the WWDC 2014 intro to CloudKit session. Basically, you use the fetchUserRecordIDWithCompletionHandler: method on CKContainer. But there's no way to link this to the Apple ID automatically-- you still need to ask the user if you want that.
Not that I am aware of. That's kind of "invading" the user's privacy because you'd be getting his Apple ID (which is an email) without his consent.
What I do, using Parse SDK, is to make the user log in anonimously at my Parse App, then save his automatically generated User ID in a iCloud Key-Value container. Whenever the user deletes the app and reinstalls it (or simply install in another device of his), my app knows that he has an username saved on iCloud and then uses that instead of creating a new user. This way, I get to keep track of my users without invading nobody's privacy.

can I use this method to store the user post and activity in the device, also store the user activity in my database without login, do you think Apple will reject my application?
Console.WriteLine(CrossDeviceInfo.Current.Id);

No need to worry, for a long time developers cannot read the real device id on iOS. The id that you get with this is a fake one so that no one can track users across all apps. But it will be consistent for your own apps so you can identify users there.
I went through almost all the related SO questions, googled lot, but I can't get help.
There are lot many posts and SO answers which states to use [UIDevice identifierForVendor], but as this Id is not visible to user, I want different way to uniquely identify the device.
Basically I am developing Enterprise app which will not going to App Store(no need to worry about private APIs).
I am having server which has all users details including device id(don't know what to use as device id) already entered.
When device launches app, web service will be called and it needs to send device id to authenticate the device.
That's why I need device id which will be visible to user as well as programmer.
Any help is appreciated!!!
Update
'Visible to user' means user can see this unique id before installing app, so as he/she can send this number to admin to register it on server.
If this unique id is registered on server then and then only access will be given to application, otherwise app will not connect to server.
Use
NSString* uniqueIdentifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
NSLog(#"UDID:: %#", uniqueIdentifier);
You've to put a small case to check the app is running on simulator or on device.
You can no longer get a unique ID of device. "identifierForVendor"
is the best you're going to get. Apple has systematically disabled
identifying a specific device.
Though, "identifierForVendor" value also changed after every new installation of application.

You're also confusing me with this line "visible to user", could you please be more specific about it?
There's also one more way - Using icloud kit you can get a unique token of currently logged In icloud user account. This is unique per application on device.
It seems you want to track user using unique ID or UDID and Apple doesn't like this so before moving forward please visit.
Update:
If Apple is preventing tracking users using Unique Id, you shouldn't be using it then.
You simply want to validate user on your server. The best solution for you is iCloud token,
Fetch it and store it in User defaults or Keychain and use anywhere you want.
In this way you can also track single user on different devices if he/she is using multiple devices with same iCloud account.
You can try obtain UDID of device via service http://get.udid.io and then authenticate this device on your server.
But after this you will need to obtain the same UDID in your apps to pass it to server... It is possible to pass UDID to app via specific URL schema.
What do you think about this idea? I can share more details if you like it.
My iOS app is currently on beta in TestFlight, and as a way to retribute to the nice people who helped me test it I would like to offer them some goodies such as, for instance, the full final version of the app for free.
For this, I was thinking of sending them a last beta version which would, automatically and upon execution, store some kind of ID from the logged in user into a VIP list I would keep online and then every next version of the app would check for their ID in order to verify if the user is a VIP user and unlock all the premium features.
Is it possible to obtain in the Cocoa apis a unique identifier that is associated to the user (as opposed to the device unique identifier)? I want this because I want to recognise the user in whatever device he installs it. I would like to avoid having to make my beta testers manually register as VIPs.
Thanks!
Yes, this is possible using CloudKit. You'll need a CKContainer, and you'll ask it to fetch the user record ID. That record ID is unique for your apps, but is also stable for that user this means the same iCloud account will have the same record ID, regardless of which device they're running on or which of your apps they're using.
If you turn on the CloudKit capability for your project, Xcode will automatically create the iCloud container for you, and you can then access it using one of the two CKContainer constructors.
According to this CloudKit overview:
CloudKit also enables your users to anonymously sign in to your apps with their iCloud Apple IDs without sharing their personal information.
I can't find anything else in their documentation about this capability. I already have an app with my own backend, so I wouldn't need any of the back-end-as-a-service features that CloudKit offers, but I would like to take advantage of logging a user in with their iCloud account, much the same way we currently do with Facebook and Twitter.
Is that possible with CloudKit, or do you also have to leverage their BAAS features in order to take advantage of login?
From what they discussed at WWDC, you'd do this using the fetchUserRecordIDWithCompletionHandler: method on CKContainer. That returns a CKRecordID that corresponds to the current user. This ID will be stable across devices but different for each app-- so if the same person uses your app on multiple devices, your app will get the same result everywhere, but other apps would get different results from yours.
Once you have the CKRecordID you can look up limited other user data (their name and email, I think) using fetchRecordWithID:completionHandler:. This request will trigger a permission alert to the user, so you only get it if they allow it.
This doesn't require you to use anything else in CloudKit. It does require that the user actually have an iCloud account configured on the device.
The permission alert will only pop if you call -[CKContainer requestApplicationPermission:CKApplicationPermissionUserDiscoverability...].
If the user grants permission (CKApplicationPermissionStatusGranted) then you can get the user's first and last name by running a CKDiscoverUserInfosOperation.
Requesting discoverability means that you can see the user's first and last name, and that any other user of the container can find their user record ID via an email address or look up their first and last name via a user record ID.
I'm trying to learn about iCloud. I've read that there's
ubiquityIdentityToken and it's used to determine if iCloud is available or if the user changed the account signed in. Also, this is only available in ios 6+
But what i need to know is the unique data for every iCloud user. What i'm saying is, after the user logs into iCloud, is there a way for us developers to know who that persons is/who the account belongs to like a username or id (similar to Facebook's fbid/identiferForVendor)? Could we even get the iCloud account of the user in code?
The reason why I want to know this is because i want to check if it's possible to use the user's iCloud account(or whatever unique data we could get from them) as the user's unique identifier on our server.
I hope I could get some answers. Thank you so much!
You can use CKContainer.fetchUserRecordID(completionHandler:)
Returns the user record ID associated with the current user.
https://developer.apple.com/documentation/cloudkit/ckcontainer/1399191-fetchuserrecordid
This article shows example of practical usage of record ID retrieved in this way: Onboarding without Signup Screens.
Apple don't want you to do this. That is why they give you a unique token that is opaque. You can't use it as an id on your server. Apple do not allow iTunes accounts to be used in that way at this point in time.
I suggest you use your own account names, or you use accounts from Facebook or Twitter, which are accessible via system APIs on iOS.
