class ApplicationController {
    let coreDataStack: CoreDataStack
    let mfpService = MFPService(username: x, password: y)

    init(coreDataStack stack: CoreDataStack) {
        coreDataStack = stack
        let _ = integrator
        let _ = rootFlowController
        let _ = window
    }
    
    lazy var rootFlowController: FlowController = {
        return SessionFlowController(coreDataStack: self.coreDataStack)
    }()
    
    lazy var window: UIWindow = {
        let window = UIWindow(frame: UIScreen.mainScreen().bounds)
        window.backgroundColor = UIColor.whiteColor()
        window.rootViewController = self.rootFlowController.rootViewController
        window.makeKeyAndVisible()
        return window
    }()

  
    lazy var integrator: IntegrationService = {
        let coreDataProcessor = CoreDataReportProcessor(stack: self.coreDataStack)
        let integrator = IntegrationService(provider: self.mfpService) {
            coreDataProcessor.processReports($0)
        }
        integrator.fetchEvery(interval: 5.hours)
        integrator.fetch()
        return integrator
    }()
}

How about Option 2 - lazy var’s with side-effects + builders ?
