I am having a consistent problem with iOS Settings not showing up after the first launch of a new app. Existing apps appear to be OK.
In the build phase, I have a script which used for some modification but that script has been executed as pre-action.
I compile/build/run in Xcode to Simulator or to iPhone with Xcode 7.2.1.
The first time I run it the settings appears. Run the app again the same way and I get blank sheet where Settings for this app used to be.
I see the Settings for this app just the one time. I can switch back and forth and the Settings remain visible, the blank sheet only appears on 2nd and subsequent launches of the app from Xcode.
The Navigation bar is visible throughout but in the blank case there is absolutely nothing below it excluding system option.
UPDATE
I have following code which copies the required Root.plist into the main Setting bundle.
if [ "${CONFIGURATION}" = "Release" ]
then
cp "${SRCROOT}/Product_Settings.bundle/Root.plist" "${SRCROOT}/Settings.bundle/Root.plist"
elif [ "${CONFIGURATION}" = "Debug" ]
then
cp "${SRCROOT}/Develop_Settings.bundle/Root.plist" "${SRCROOT}/Settings.bundle/Root.plist"
fi
Develop_Settings : Development Setting bundle
Product_Settings : Production setting bundle
