Hi @FiRiN59

Right now you can listen to when our SDK has started via https://segment.com/docs/sources/mobile/ios/#how-do-i-know-when-an-integration-is-initialized- and then set the delegate manually on the sharedInstance. e.g.

[Appboy sharedInstance].appboyEndpointDelegate = myDelegate

Optionally you can also modify the SegAppboyIntegration.m in this repo to directly create and pass your delegate into our init method.

We'll aim to get the process more seamless in an upcoming release - please let me know if the above methods aren't working for you.

Thanks,
Brian
