Why Is Icloud Account/Ckcontainer Not Being Found

Why is iCloud account/CKContainer not being found

According to the documentation,

The private database is available only when the value in the ubiquityIdentityToken property is not nil.

It also says

There are times when iCloud may not be available to your app, such as when the user disables the Documents & Data feature or signs out of
iCloud.

Documents and Data is now apparently what is called iCloud Drive in Settings.

So I would ask the users in question if their iCloud Drive setting is enabled and if turning it on makes any difference.

CKContainer fetchUserRecordIDWithCompletionHandler returns nil CKRecordID when iCloud Drive is disabled

It's working as designed. iCloud Drive is a requirement to use CloudKit. This is documented in the CloudKit Quick Start.

Look under the Enter iCloud Credentials Before Running Your App section.

CKContainer accountStatusWithCompletionHandler returns wrong value

Figured out, iCloud Drive was turned off for the app.

iOS No iCloud account is configured

I logged out of iCloud and logged back in and then in worked.

@matt answered correctly

CloudKit and iCloud account

if users don't have an iCloud account they won't be able to update the public database?

From Apple's Designing for CloudKit doc:

Saving records to the public database and accessing the private database in any way requires the presence of an active iCloud account on the device.

So you're right.

can the apple account (the one the user needs to download stuff from the apple store) wouldn't be enough to update the public database and gain access to the private database?

This is a slightly unclear question - cases where an Apple ID is set up to download from the App Store and isn't set up for iCloud are very rare. I would assume that nearly all devices that can download your app likely have an iCloud account attached to them.

Cloudkit Authentication Only works on my alt account and not Dev or Tester accounts

It was a bug with CloudKit. Sometimes the container can be broken on creation apparently.

I was able to fix it by creating a new container in Xcode (on the config screen for your app) and unchecking the old one. Then I configured the new container from scratch, adding all the data types and configuring the security roles (roles take like 5min to kick in so just keep checking/trying).

Check if User is Logged into iCloud? Swift/iOS

Here you go - hopefully self explanatory. For more look at the Apple docs for the NSFileManager function below.

func isICloudContainerAvailable()->Bool {
        if let currentToken = NSFileManager.defaultManager().ubiquityIdentityToken {
            return true
        }
        else {
            return false
        }
    }

See extract below:
An opaque token that represents the current user’s iCloud identity (read-only)
When iCloud is currently available, this property contains an opaque object representing the identity of the current user. If iCloud is unavailable for any reason or there is no logged-in user, the value of this property is nil.
