I created an App using PeerNetworking to connect two iOS-Devices without existing wifi-infrastructure. In general the solution works fine but when there are many other smart devices nearby connection gets unstable and breaks, devices have to be closer together or dont connect at all. In "Lab"-conditions everything works fine. What could I do to get the connection more stable and reliable?

Hi, i programmed an app the uses MultipeerConnectivity to connect iOS-Devices to exchange Video-Files from the camera (https://pellepepper.my.canva.site/jumpcontrol). In general the solution works fine but I have some challenges: The connection is pretty stable when there are only few other devices around. It seems to become more fragile when there are more other iOS-Devices in the area Testing of the App worked with several meters of distance (up to 10). In real environments of athletics venues the solution is only stable in a region of about 2 meters It seems that newer iOS-Releases make the connection more unstable. Last weekend we used it with iOS 18-Devices on older hardware, what worked fine. Integrating an iOS 26 device made trouble. Working on iPhone 13 with iOS 26 is hardly not usable. What can I do to improve stability of the connection and therefore the App. What are the metrics to look for? Is there something I can do on the code base to make to connection more stable? Many thx Rainer

I tried to migrate some code to SwiftData and Observable...doing this I wanted to mark a ViewModel-Class with @observable but get errors when using it in combination with didSet. What's wrong with it?! @Observable struct LADVAthletes { var queryName : String = "" { didSet { guard oldValue != queryName else { return } guard queryName.count < 2 else { athletesList.removeAll() return } } } var athletesList : [Athlete] = [Athlete]() } I get multiple Errors saying "Cannot find 'oldValue' in scope" "Instance member 'queryName' cannot be used on type 'LADVAthletes'; .... And so on... What's wrong with it?!
