UE support UPL with iOS since 4.13 update.

Android example is exist in /Engine/Plugins/Runtime/GearVR/Source/GearVR/GearVR_APL.xml

but iOS example is not exist.

I try below upl xml code.

<?xml version="1.0" encoding="utf-8"?>
<root>
	<!-- init section is always evaluated once per architecture -->
	<init>
		<log text="IPL init"/>
        <copyDir src="$S(PluginDir)/ThirdParty/iOS/resource/"
        dst="$S(BuildDir)/" />
        <log text="IPL resource -> $S(BuildDir) copy done"/>
	</init>
    <iosPListUpdates>
        <log text="IPL In iosPlistUpdates...."/>
        <insert>
            <key>CFBundleVersion</key>
            <string>0.4a</string>
        </insert>
    </iosPListUpdates>
</root>

init process is normally passed.

but iosPlistUpdates is not passed.

what’s wrong with this?

I saw that upl use “iosPlistUpdates” keyword in “UEDeployIOS.cs”…

using Node in 4.13… could’t compile.

Is there bug???

I believe there may be a bug with iosPListUpdates I have submitted a pull request to have it corrected. Please look at the UnrealEngine git repo and look for pull requests from me “robertfsegal”.

In 4.14 still the same problem…
