Development (HederaProtobufs)

HederaProtobufs is entirely generated

Required tooling

protoc protoc-gen-swift (from https://github.com/apple/swift-protobuf) protoc-gen-grpc-swift (from https://github.com/grpc/grpc-swift)

Generate services

# cwd: `$REPO`
protoc --swift_opt=Visibility=Public  --swift_opt=FileNaming=PathToUnderscores --swift_out=./Sources/HederaProtobufs/Services --proto_path=./protobufs/services protobufs/services/**.proto

# generate GRPC (if needed)
protoc --grpc-swift_opt=Visibility=Public,Server=false --grpc-swift_out=./Sources/HederaProtobufs/Services --proto_path=protobufs/services protobufs/services/**.proto

Generate Mirror

# cwd: `$REPO/sdk/swift`
protoc --swift_opt=Visibility=Public --swift_opt=FileNaming=PathToUnderscores --swift_out=./Sources/HederaProtobufs/Mirror -I=protobufs/mirror -I=protobufs/services protobufs/mirror/**.proto

# generate GRPC (if needed)
protoc --grpc-swift_opt=Visibility=Public,FileNaming=PathToUnderscores,Server=false --grpc-swift_out=./Sources/HederaProtobufs/Mirror -I=protobufs/mirror -I=protobufs/services protobufs/mirror/**.proto

Integration Tests

Before running the integration tests, an operator key, operator account id, and a network name must be set in an .env file.

# Account that will pay query and transaction fees
# Default private key to use to sign for all transactions and queries
# Network names: `"localhost"`, `"testnet"`, `"previewnet"`, `"mainnet"`
# Run tests
$  swift test 

Local Environment Testing

Hedera offers a way to run tests through your localhost using the hedera-local-node service.

For instructions on how to set up and run local node, follow the steps in the git repository: https://github.com/hashgraph/hedera-local-node

Once the local node is running in Docker, the appropriate .env values must be set:


Lastly, run the tests using swift test

Generate SDK

# cwd: `$REPO/sdk/swift`
protoc --swift_opt=Visibility=Public --swift_opt=FileNaming=PathToUnderscores --swift_out=./Sources/HederaProtobufs/Sdk -I=protobufs/sdk -I=protobufs/services protobufs/sdk/**.proto
