Solved my issue with out splitting NSData into multiple parts.Just did another solution.by downloading video in iOS side and saved into documents. then transferred file to watch app using

[_session transferFile:filePathUrl metadata:metadata];"

In watch app side. using this delegate got file and placed data in shared documents. then get file path and played video. - (void)session:(WCSession *)session didReceiveFile:(WCSessionFile *)file
