# Upgrading from 9.3.0 to 9.4.0 (iOS)

- The getCurrentTime() method of the NNLITimeProvider protocol now returns Int64 (long long) instead of Int (long). If you are [customizing the time provider](/dpoa/docs/s3suite94-implementing-authentication-in-your-app-1#provide-the-time-used-for-quick-auth) by using the protocol, you need to change the return type.
- NNLISignUpProcessor protocol now requires the NSObject . If you implemented the NNLISignUpProcessor protocol, then your implementation should be derived from NSObject. For example, replace:

```swift
final class SignUpProcessor: NNLISignUpProcessor
```

with

```swift
final class SignUpProcessor: NSObject, NNLISignUpProcessor
```

You can also use the Digipass S3 Command Line Interface to set values for these environment variables, but their values revert the next time you run docker compose up.
