Can no longer build if I don't have an iOS device

[GeorgeLeithead]

When I try to build the latest main branch on a Windows machine, I can no longer get a successful build.

During build I get a dialog asking to set-up a connected iOS device. I do not HAVE an iOS device, so cancel. The build then fails, and I cannot perform a successful build.

Hey George! Have you narrowed down the problem to our code? Or is this a tooling problem or an environment problem specific to your machine?

Our CI builds the project on Windows machines without an iOS Device present. If it were a problem with our code, I imagine the CI Pipeline would fail too (which it hasn't).

@brminnick I can confirm that for me, I am often an idiot. I always use "Windows Machine" and occasionally "Android Emulator" for the target...For what ever reason, when I created a new branch and merged from main, it was set to Local Device (which I never do, as I don't have an iOS device). Didn't even occur to me to check that the target was different!

Ah - yea, I hate the way that UI Dropdown is designed in Visual Studio.

I've sen many devs hit the same problem when I've been delivering .NET MAUI workshops.
