How to fix error when trying to view app preview in swift?

Question

Apple Xcode

I am developing an application and at some point (I myself have not yet understood why) - when I tried to click resume on the view, I began to receive an error:

Build target Landmarks:
warning: Capabilities for Signing & Capabilities may not function correctly because its entitlements use a placeholder team ID. To resolve this, select a development team in the Landmarks editor. (in target 'Landmarks' from project 'Landmarks')

I went to the blueprint settings of the project, added my apple developer account, but an error began to arrive that such a project already exists, and it cannot be created.

Actually, if someone knows why it began to ask for this signature and why it does not work?

Answer 1

I solved the situation by resetting the application cache and it worked. He didn't understand what he needed.
