Previously worked on Appium 1.15.1 and non iOS13 devices. Launching settings this way still works on iOS 13 when AUT is provided.

Trying on Appium 1.17.1  
iOS 13.2.3

// Reproduction code, using JavaClient 7.3  
// Setup the appium session  
DesiredCapabilities capabilities = new DesiredCapabilities();  
capabilities.setCapability(MobileCapabilityType.UDID, udid);  
capabilities.setCapability(MobileCapabilityType.DEVICE\_NAME, “iPhone”);  
capabilities.setCapability(MobileCapabilityType.PLATFORM\_NAME, “iOS”);  
capabilities.setCapability(MobileCapabilityType.AUTOMATION\_NAME, AutomationName.IOS\_XCUI\_TEST);  
capabilities.setCapability(“bundleId”, “com.apple.Preferences”);  
iosDriver = new IOSDriver(new URL(serverURL), capabilities);

Looking to see if I need to set some other capabilities to make this happen once again?

Best Regards,

Seems likely it was more of an issue related to previous sessions not being cleaned up appropriately.

Still not certain why session bashing + simple launch preferences would fail to launch the settings app though.
