How to convert invalid UUID string to valid UUID string

Question

I am having string that i want to convert UUID

my string is - > "43pszizx-0000-0000-0000-000000000000"

i want to convert this into UUID

i have tried this code

let contactUUID = "43pszizx-0000-0000-0000-000000000000"

if let uuid = UUID(uuidString: contactUUID) {
            moviesVC.conversationID = uuid
        }

but it always returns nil

is there any solution to convert this string to UUID, this string coming from API as a contactId

thanks in advance

Do you realise that the string itself is not a valid `UUID`? You just want to generate a `UUID` based on the string, right? — Sweeper, Feb 15 '23 at 06:48
As @Sweeper pointed out the string isn't a valid UUID, and this is the reason why initialization of UUID fails: https://developer.apple.com/documentation/foundation/uuid/3126814-init What do you want to do with a string representing a non-valid UUID? — lazarevzubov, Feb 15 '23 at 06:55
Hi @lazarevzubov, i want a static UUID for each user, and it should not change — Jayaseelan Kumarasamy, Feb 15 '23 at 07:04
Ugh. You can't have a UUID from a string that is not a UUID. — lazarevzubov, Feb 15 '23 at 15:59

As per the doc

Returns nil if the string isn’t a valid UUID representation.

let contactUUID = "43pszizx-0000-0000-0000-000000000000"
//The string representation of a UUID, such as E621E1F8-C36C-495A-93FC-0C247A3E6E5F.

But the contactUUID doesn't seems to be matching with UUID representation so its always returning nil
