Simulator initialization

I am getting an error trying to see the simulator for the app examples. I get the following info.

NoBuildableEntriesError: active scheme does not build this file

Select a scheme that builds a target which contains the current file, or add this file to a target that is built by the current scheme.

it works fine for my own code but the app examples do not work. I can view them in the separate simulator program. Is there some parameter I need to change in these examples?


Hi Colin,

Welcome to the community.

Can you provide a screenshot of your entire Xcode window when this error/warning occurs?

Use the keyboard shortcut Shift + Command + 5 (that is the number 5 not the letter S) to invoke the Screenshot App to allow you to capture an entire Application Window.

I think this is it.


There is nothing obvious that springs to mind.

Can you share the contents of your ViewModel.swift, Pizza.swift and ContentView.swift files?

Paste your code in as text, rather than providing a screenshot.

To format the code nicely, place 3 back-ticks ``` on the line above your code and 3 back-ticks ``` on the line below your code. Like this:

Code goes here

The 3 back-ticks must be the ONLY characters on the line. The back-tick character is located on the same keyboard key as the tilde character ~ (which is located below the Esc key).

Alternatively after you paste in your code, select that code block and click the </> button on the toolbar. This does the same thing as manually typing the 3 back ticks on the line above and below your code.

This also makes it easier for anyone assisting as they can copy the code and carry out some testing.
