Unused method argument - application. If it's necessary, use _ or _application as an argument name to indicate that it won't be used. You can also write as application(*) if you want the method to accept any arguments but don't care about them.

Use snake_case for variable names.
Open

  def application(application, didFinishLaunchingWithOptions: launch_options)
Severity: Minor
Found in app/app_delegate.rb by rubocop

This cop makes sure that all variables use the configured style, snake_case or camelCase, for their names.

Example: EnforcedStyle: snake_case (default)

# bad
fooBar = 1

# good
foo_bar = 1

Example: EnforcedStyle: camelCase

# bad
foo_bar = 1

# good
fooBar = 1

Missing top-level class documentation comment.
Open

class AppDelegate
Severity: Minor
Found in app/app_delegate.rb by rubocop

This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, or constant definitions.

The documentation requirement is annulled if the class or module has a "#:nodoc:" comment next to it. Likewise, "#:nodoc: all" does the same for all its children.

Example:

# bad
class Person
  # ...
end

# good
# Description/Explanation of Person class
class Person
  # ...
end
