after the latest update of Xcode 10 I have the problem that when I try to build and install the app to my IPhone 7, Xcode seems to install the app, but I cannot see any changes when I try to change for example a color or a constraint in Main.storyboard.

Try restarting the phone.

Different issue but I was having an issue running an XCUITest on device after upgrading to Xcode 10, and restart solved it.

Quit Xcode and the simulator and then Restart you computer.

If that doesn’t work try using a different simulator.
