$cordovaSplashScreen not hiding on IOS

I have a project using cordova-plugin-splashscreen v 3.1.0 .. but now I can't hide the splashscreen anymore on IOS .. so I use

$cordovaSplashscreen.hide();

to hide ..

So I opened an other project wich uses v3.0.0 and there

$cordovaSplashscreen.hide();

works

Has anybody expierenced this?

my config.xml

  <preference name="SplashScreen" value="screen"/>
  <preference name="ShowSplashScreenSpinner" value="true"/>
  <preference name="AutoHideSplashScreen" value="false"/>
  <preference name="SplashScreenDelay" value="50000"/>
  <preference name="FadeSplashScreen" value="false"/>
