Ionic DevApp Splash Screen is white?

Here’s what I’ve done:

ionic start myApp tabs
cd myApp
** Updated resources/icon.png and resources/splash.png
ionic cordova platform add ios
ionic cordova platform add android
ionic serve

But when I’ve opened the application, using the Ionic DevApp (for iOS), I saw a blank splash screen.

Any help, please?

It seems that DevApp doesn’t show the correct splash screen - when I builded it for iOS and Android - it appeared correctly.
