I had to regenerate Xcode project and when I did this I got an error:
package at '/Users/sergey/Desktop/TILApp' is using Swift tools version 3.1.0 which is no longer supported; consider using '// swift-tools-version:5.2' to specify the current tools version
I ran swift package --set-current. After this I got another errors (actually bunch of them):
dependency 'FluentPostgreSQL' in target 'App' requires explicit declaration; provide the name of the package dependency with '.package(name: "FluentPostgreSQL", url: "https://github.com/vapor/fluent-postgresql.git", from: "1.0.0")'
I changed every package in Package.swift and finally got this error:
declared name 'Authentication' for package dependency 'https://github.com/vapor/auth.git' does not match the actual package name 'Auth'
