Swift Compiler Error for LocationPermissionsDelegate

I'm getting the following errors. I tried to look up information on the errors but found nothing.

Cannot invoke initializer for type 'LocationManager' with an argument list of type '(permissionsDelegate: PermissionsController)'

Use of undeclared type 'LocationPermissionsDelegate'

'weak' may only be applied to class and class-bound protocol types, not '<<error type>>'

Please post your code on Github so we can see your full code to diagnose the error

You must declare permissionsDelegate like this

weak var permissionsDelegate: LocationPermissionsDelegate?
