BTW killing CoreSimulatorService did not work. Weird enough, the project compiles and runs on a physical iphone.

Hi. I tried both creating a clean new project and opening an old one created from the previous Xcode version. Actually both simulator and storyboard issues seem to stem from the same point: ios 27 platform component cannot be detected even though it is installed. Attached is a storyboard created in version 27. Main.storyboard

I'm in a pretty similar situation. Because of a bug in Connect, I can't submit a very critical update for review for a whole month! I've been waiting for a fix from engineering team at Apple. At some point in time they stopped responding to my inquiries. Weird enough, somehow nobody answers my calls to Developer Support line for the last 10 days (yesterday I waited for 1.5 hours on the line). When they were answering, they were telling me that Dev Support gets congested during WWDC week, but even that congestion shouldn't have taken this long. I really don't know what to do.

Hi how should we do the same in C#?
