How to get unqiue id for every device not for every app?

Question

I want to know one unique id per device but not for per app in one device. I am building one framework where I want to use this device id.

There is no such id available, vender id is the only unique id that u get but that might change if user uninstalls and reinstalls ur app, if you are supporting iOS11 and above, device check API might come handy depending on what exactly you are trying to achieve. — Sandeep Bhandari, Jul 31 '18 at 08:18

UUID is unqiue to app not to device. – user2343049 Jul 31 '18 at 09:18
No, UUID isn't even unique, it generates a random string every time it is called – il3v Aug 13 '18 at 16:11

Just create a unique number by yourself and then store it in the device keychain.

In device keychain If I store in one device, it can't be accessed on every app on that device. – user2343049 Jul 31 '18 at 09:17
enable keychain sharing which will allow you to access unique id among apps. – Ellen Jul 31 '18 at 09:54
@Ellen - keychain sharing requires same developer team. For me my framework will be used in different apps signing with different developer team. – user2343049 Jul 31 '18 at 10:18
