I’m designing for a new customer some app’s for their iPad’s.
One of the app’s has to be a kind of server of al kind of collected data.
I did many of these technics on Mac and Win and was always using the perfect Xojo ServerSocket 
What is the best approach on iOS?

I bumped into the same requirement for my own app and filed a request long, long ago in the far away age of beta testing, when I still believed things were possible for iOS (how naive) : <https://xojo.com/issue/36856>
Since obviously nothing ever happened, I ended up using a web app to connect to. On a Lan, you can probably do the same with a Desktop machine.
Sandbox makes it hard for iOS apps to “share” common storage locations, but it seems I read it is possible (but difficult), and Apple may be really strict about approving such. I’m going to see if I can find information, but it will probably be something that cannot be done in XOJO for iOS, and may require ObjC or SWIFT.
Of course, using the “Cloud” might be a possibiltiy as well
There is an excellent article about the subject at
https://www.raywenderlich.com/3932/networking-tutorial-for-ios-how-to-create-a-socket-based-iphone-app-and-server
But of course it is not for Xojo.
It would be amazing to create a Web App embedded in an iOS app.
So, in short:
iOS doesn’t have a ServerSocket class
iOS doesn’t have a xojo.Net.TCPSocket.Listen method
My project has to function even if there is no internet available.
My project has a running WiFi network for local traffic.
If I need to exchange data between all the iPad’s I have to create a desktop ServerSocket app who is connecting everything.
Are there possibilities for a MBS kit @Christian Schmitz ?
Untrue. XOJO for iOS may not, but Sockets ARE available in the iOS operating system

Therefore you DO have an INTRANET available, programming differences would be minimal
If the updates don’t have to be “live/realtime”, you have the option of using iTunes filesharing, heck you could even resort to email… not the best thing… but it is an option
Are you saying Norman, that socket.Listen will be possible when I wrap call’s to Apple’s framework?
Just that Apples doc suggest that it is possible to write a server on iOS
Declares may suffice
