Inherit static library into appdlegate

We are trying to integrate an SDK developed in Objective C to iOS app developed in Swift. The SDK’s static library is inherited into App delegate class. Is this an accepted standard per Apple guidelines ? I wanted o check the same to avoid app rejection on submission to store.

Eg : AppDelgate.swift

class AppDelegate : MystaticLibrary,UIApplicationDelegate {
               //My code
     }

MystaticLibrary

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
//My Code
}

Thanks in advance!
