SwiftUI in ObjectiveC Project - List works in preview, not when it is run
Solution 1:
I think this is due to constraints, try use instead following
...
view.addSubview(swiftController.view)
swiftController.view.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
swiftController.view.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
swiftController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
swiftController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
