Look at the crash log. It says that you bundle can't load DAVKit. Framework so the easiest way - its rebuild ConnectionKit framework but instead of embedding DAVKit.
Xcodeproj insert all sources of DAVKit. Its easiest way but more correctly - its setup install path of ConnectionKit and DAVKit frameworks. Its link should help you: embedding frameworks in loadable bundles.
You should link your bundle with DAVKit and include it there In the same way as you're including ConnectionKit. This avoids having multiple depths of frameworks being shipped.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
