I have an Xcode project on my older Mac that I finished building (Xcode version 9.4.1). There it workes fine and it is ready for the upload in the AppStore. Because My Mac can't run macOS mojave I borrowed another Mac with the latest Xcode Version (10.1) when I run the project there I get the following exception:

I ran the project on my old mac on my external harddrive and it worked fine. After that I tried running the project on the newer mac on the external harddrive but it did't work.
I checked all classes and every class is connected right.
I also deleted the connection of the outlets and reconnected them. It chanched nothing.
Thank you in advance,
Manuel
