I’m unable to get ODR working either in our project or in the AssetBundleDemo sample project using Unity 5.5.2p1 and Xcode 8.3. ODR is enabled in player settings, and I’ve turned on “Embed Asset Packs in Product Bundle” in the build settings to be able to test locally. The code runs but any ODR requests come back with no error but no assets in them (ultimately crashing when the sample tries to access the resources). If I examine the generated project in Xcode, all the data sets in UnityData.xcassets are empty - they’ve been created but have no assets in them, which I assume is the problem and not using the embed option. Am I missing a setup step somewhere?
