Mobile Couchbase for iOS is delivered as an embeddable library with seamless Apple Xcode IDE integration, ensuring a familiar development experience for developers building iPhone and iPad apps.

On the horizon for Mobile Couchbase is a feature we think will be crucial for adoption with more apps: ObjC Map Reduce. With ObjC Map Reduce we can make the Spidermonkey dependency optional, thus cutting the overall download size contribution of Mobile Couchbase by roughly half.
