Why
Flicker was reported on iOS in-between SplashScreen and ReactApp phases: https://expo-developers.slack.com/archives/C04Q3JTSV/p1591378610268800
How
Native SplashScreen View was added in
async
manner and that was causing some small gap while actual iOS Launch Screen was already hidden and custom view fromexpo-splash-screen
was not yet added properly.I've changed that to
sync
manner and also added handlingRCTRootView.loadingView
as described in https://reactnative.dev/docs/running-on-device#pro-tips.Moreover added proper resizing of the UIView coming from
.xib
file.Test Plan
Installed in
bare-expo
and step by step debugged view hierarchy breakpointing between SplashScreen-related functions.Changelog
