I have Swift project and added FCUUID throw pods. And now I don't now how to use it. Import can not find FCUUID framework. Please can you write/describe fully FAQ integrating into Swift project

Does it possible to keep device id when i transfer app to another developer account?

What Happens if iCloud is Sync Keychain and try to get device ID on 2 devices with same iCloud account.

Key-value storage enabled (target / Capabilities / iCloud / Key-value storage)

Same device, different signature,got different id?
[FCUUID uuidForDevice]

Not sure if I'm getting it right but based on the persistence table, the uuidForInstallation is expected to be removed when the app is uninstalled. However, that's not the case (tested on iOS 9 and 10). Probably because of the following line:

_uuidForInstallation = [self _getOrCreateValueForKey:_uuidForInstallationKey defaultValue:nil userDefaults:YES keychain:YES service:nil accessGroup:nil synchronizable:NO];

I believe keychain argument should be NO here.

At these conditions:

1. 9.0 -> 9.1 (within 9.x)
2. 9.0 -> 10.0

how to set the "Keychain Access Groups"?

Hi,

we're currently seeing the case where 2 different iPads, which use the same apple ID would generate the same UUID, which is obviously not what one wants.

We don't know for sure, but it seems it all started with around iOS ~16.6.1.

Is anybody else seeing this, or even knows a fix for it?

Thanks a lot!

Hi, I find your library is perfect to accomplish my client's app requirements and identify users. I'd need to use the uuidForDevice method to identify the user device. However I have a few questions:

-As I understand your library, it relies in NSUbiquitousKeyValueStore to persist across installations but, what happens if the user is logged out or even never created a iCloud account? This app is meant to be used mostly by old people so this can be an usual scenario. If this is the case, there's nothing to do, Am I right? Or there is any kind of automatically generated iCloud id created on iPhone activation?

-Can you identify just the current device instead of every user devices?

Thank you very much

When i want to get uuid after the system is reinstalled, i must log in to iCloud ?

Why is the ID generated by the two devices the same?

Hi Team,

First, thanks for the work!

Would you consider an update if I do a PR with Carthage support?

Cheers,
Vincent

同一个设备登录多个appid,同步了keychain信息的话，会导致获取的uuid发生变化吗？会被新的appid中的keychain信息覆盖掉？

I use FCUUID as NSString *deviceUUID = [FCUUID uuidForDevice];，but` same ID，one iphone ，two UDID，log is NSUbiquitousKeyValueStore error: com.xxx.xxx has no valid com.apple.developer.ubiquity-kvstore-identifier entitlement，can you help me?

"uuidForDeviceInMemory" is nil and calling "isEqualToString" on it causing crash.

line number in code

EDIT:

So here the scenario to generate
Use the UUIDForDevice, and then delete the app and reinstall it again,

ios11 will release , new device will come

• I need unique id for my project so I have used this framework but then I realise it returns same user device id for same iCloud account

whether this library is limited on iOS 14.5?

thanks !

Hey @fabiocaccamo, I'm having an issue when restoring a device using iCloud.

So, we are using uuidForDevice to have a unique id per user per device, but we are facing some issues when people are cloning their devices and as the uuidForDevice is the same (they do a full backup with encrypted data and everything), then for our system, the "new" app is the same user/same device.

Is there any chance to prevent this behavior? we might have users paying just for one device when they could be using several ones.

Thanks in advance!

Before using i want to ensure does this plugin support ios7 and ios8. what it will return as UUID ? is it macid?

Will two different apps in two different devices generate the same id?
ps: Key-value storage disabled ，two different bundle IDs

When I upgrade my device system, will uuid change?
