Crash when using [self.manager stop]

[jamesLapinski]

Bug Report

We are attempting to stop the proxy when a Lincoln branded app attempts to appear on a Ford unit (and vice versa) by using [self.manager stop], which causes a crash.

Reproduction Steps

1. Insert the following into the didReceiveRegisterAppInterfaceResponse method. In this example I was using the hello_sdl_ios project.

 if (![response.vehicleType.make isEqualToString:@"Lincoln"]) {
        
        [self.manager stop];

    }

2. Run the app.

Expected Behavior

The expected action would be the app attempting to open on the TDK and then immediately closing.

Observed Behavior

The app crashes with the error message 'Invalid state machine SDLStateMachine transition of target SDLFileManager occurred from Shutdown to StartupError'

OS & Version Information

• iOS Version: 11.1.1
• SDL iOS Version: 5.0.0-rc.2
