iOS Handoff and ubiquity key-value store sample
Works together with https://github.com/bzhoek/handoff-mac to demonstrate Handoff and the Ubiquity key-value store.
For ubiquity to work, both .entitlements files need to have the same value for com.apple.developer.ubiquity-kvstore-identifier, i.e. $(TeamIdentifierPrefix)com.zilverline.classroom.
