I can't run the RestaurantFinder app in the simulator in Xcode.

I downloaded the source code for the RestaurantFinder from the iOS Development with Swift 2.0 course and I keep getting this error:

A build only device cannot be used to run this target.

No supported iOS devices are available. Connect a device to run your application or choose a simulated device as the destination.

Xcode 7.2.1

I downloaded the RestaurantFinder app from Treehouse.

You might want to update to the latest (7.3.1). RestaurantFinder has a Deployment Target of iOS 9.3, which I believe is the version that ships with Xcode 7.3.1.

I suppose you could also try lowering the deployment target, but then you may run into API compatibility issues in the project.

Hi Aaron,

I've seen this before, too. I believe you need to go to the device dropdown menu and select a simulator device. Right now it probably says, "Generic iOS Device". Click on that and select something like 'iPhone 6 Plus'. Hope that helps. (I'd post a screenshot, but I am not sure if it's possible here.)

Only Generic iOS Device is listed.

Ok. What version of Xcode are you running? This might be a mismatch between the Xcode version of iOS and the version the RestaurantFinder project is targeting.

I am updating the Xcode now.

Hopefully this won't take too long.

I'll reply back once Xcode has finished updating.

Thanks again for everything!
