Help with an error message

I have created a programme that which has this error message and when it runs the phone screen does not show anything. This is the error message, can anyone help?

Warning: Error creating LLDB target at path ‘/Users/paulweekes/Library/Developer/Xcode/DerivedData/mvvn-demo-gryziphwxwnxzlfcjqgikrltanng/Build/Products/Debug-iphonesimulator/mvvn-demo.app’- using an empty LLDB target which can cause slow memory reads from remote devices:

error: failed to launch ‘Could not attach to pid : “82471”’ – Xcode has killed the LLDB RPC server to allow the debugger to detach from your process. You may need to manually terminate your process.

Hi Paul,

Welcome to the community.

I have not seen that one before.

When you created the App, what options did you choose on this screen?

and what Interface type did you choose on this screen?

Also, what name did you give your project?

Maybe post a screen shot of your entire Xcode window. Similar to this image.

Thank you so much for taking the time to come back to me.
