I'm trying to connect my App to Firebase, I already followed the steps given in the site itself, in addition to seeing some videos from other authors, however I always encounter the following problem:
Could not locate configuration file: 'GoogleService-Info.plist'.
This file has already been downloaded and even added to the required folder, as can be seen in the image below:
This error has already been corrected, in addition to dragging the GoogleService-Info.plist file to the appropriate folder, it is also necessary to indicate its directory in the Show in file inspector panel, besides marking the project in the Target Membership option, as it can be seen in the image below:
Select the file and in the right tab of Xcode, in the Target Membership option you select.
