IPhone : How to create build(.ipa or .app) in iWatch

Hi I am developing a app with iWatch extension, But I was unable to create build. Every time faceing some error like :

Code Sign warning: Specified PROVISIONING_PROFILE (***********************) not found and no CODE_SIGN_IDENTITY specified. Ignoring PROVISIONING_PROFILE for now. This will become an error in the future.

CodeSign error: code signing is required for product type 'WatchKit Extension' in SDK 'iOS 8.2'

Is there any option in apple deveoper account (in bundle identifier or provision profile) to select for iWatch Extension ?

Please suggest.

Thanks in advance
