Error running app with gRPC pod install on actual iOS device -

i trying integrate grpc ios app

i using current branch of grpc objective c.

i have integrated .podspec file , can build , run ios app in simulator mode, when try build , run app on actual iphone 6s following error

dyld: library not loaded: .framework/grpc referenced from: /var/containers/bundle/application/05197094-48b9-4fa9-9d4d-68ed83817c0f/myapp.app/myapp reason: image not found (lldb)

when remove pod app builds , runs on iphone, grpc, have tried adding grpc.framework embedded framework, nothing.

any ideas?

here .podspec
