On iPad 4 (iOS 10.3.3) when i'm trying to update a value i'm getting this exception: The specified item already exists in the keychain.

this is how i use it:

 let keychain = Keychain(service: key).accessibility(.afterFirstUnlock)
 do { 
       try keychain.set(value, key: MyKey)
        } catch let error {
            print(error.localizedDescription)
        }

I just ran into the very same issue, it only happened once at app boot/session start and then never again. Does anybody know what could be the cause and how to avoid it in the future? For now I've added a removal of the items before trying to set them again to avoid this issue in the future but I'm not sure if this is a good idea or not. Anybody here who could share some light on the best practices for when the keychain can't be written to?

I'm seeing this issue running under iOS 17.4.

This merged PR into Flutter Secure Storage repo, merged earlier this summer, seems interesting:
