Lnd: [mobile] grpc: no transport security set

[ealymbaev]

Background

I have launched LND on iOS via gomobile and all your instructions (using falafel). I am able to start LND node and see all logs. But I cannot make any gRPC requests because of the following error:

Error Domain=go Code=1 "grpc: no transport security set (use grpc.WithInsecure() explicitly or set credentials)" UserInfo={NSLocalizedDescription=grpc: no transport security set (use grpc.WithInsecure() explicitly or set credentials)}

Your environment

Also please note that I am using new nio branch of grpc-swift as they recommend.

• version of lnd: lnd v0.9.0-beta-rc1
• which operating system (uname -a on *Nix): OSX
• version of btcd, bitcoind, or other backend: Neutrino
• any other relevant environment details

Steps to reproduce

LndmobileStart succeeds and I see all the logs. But any gRPC request (LndmobileInitWallet or LndmobileGenSeed) does fail with the error above.

I have also created related issue on grpc-swift repo:

Should be fixed by https://github.com/lightningnetwork/lnd/pull/3907.

I have tested the latest changes in repo and it DOES work. Thank you, great work.
