Swift Client for TVM SDK (everscale, venom, gosh)

Swift is a strongly typed language that has long been used not only for iOS development. Apple is actively promoting it to new platforms and today it can be used for almost any task. Thanks to this, this implementation provides the work of TVM (toncoin, everscale, venom, gosh) SDK on many platforms at once, including the native one for mobile phones. Let me remind you that swift can also be built for android.

You need to get an API-KEY here https://dashboard.evercloud.dev

Usage

All requests are async

import EverscaleClientSwift

var config: TSDKClientConfig = .init()
config.network = TSDKNetworkConfig(endpoints: ["https://net.ton.dev"])
let client: TSDKClientModule = .init(config: config)

// Crypto
client.crypto.factorize(TSDKParamsOfFactorize(composite: "17ED48941A08F981")) { (response) in
    print(response.result?.factors)
}

// Boc
let payload: TSDKParamsOfParse = .init(boc: "te6ccgEBAQEAWAAAq2n+AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAE/zMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzMzSsG8DgAAAAAjuOu9NAL7BxYpA")
client.boc.parse_message(payload) { (response) in
    if let result = response.result, let parsed: [String: Any] = result.parsed.toDictionary() {
        print(parsed["id"])
        print(parsed["src"])
        print(parsed["dst"])
    }
}

Errors

client.crypto.factorize(TSDKParamsOfFactorize(composite: "17ED48941A08F981")) { (response) in
    if let error = response.error {
        print(error.data.toJSON())
        print(error.code)
    }
}

Setup TONSDK For Linux and MacOS

Install sdk with bash script

0. This download SDK to current dirrectory, compile it and add library symlinks to your system

cd everscale-client-swift

1. For install or update the SDK version simply by running these command

bash scripts/install_tonsdk.sh

Manual install sdk ( if you have any problem with script install_tonsdk.sh )

SPOILER: Manual installation

0. Install Rust to your OS

1. git clone https://github.com/tonlabs/ever-sdk

2. cd ./SDK

3. cargo update

4. cargo build --release

5. copy or create symlink of dynamic library
   macOS :
   ./SDK/target/release/libton_client.dylib
   to
   /usr/local/lib/libton_client.dylib

   Linux :
   ./SDK/target/release/libton_client.so
   to
   /usr/lib/libton_client.so

6. Create pkgConfig file :

macOS :
/usr/local/lib/pkgconfig/libton_client.pc

prefix=/usr/local
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${exec_prefix}/lib

Name: ton_client
Description: ton_client
Version: 1.0.0
Cflags: -I${includedir}
Libs: -L${libdir} -lton_client

Linux:
/usr/lib/pkgconfig/libton_client.pc

prefix=/usr
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${exec_prefix}/lib

Name: ton_client
Description: ton_client
Version: 1.0.0
Cflags: -I${includedir}
Libs: -L${libdir} -lton_client

7. Copy or create symlink of file
   /SDK/ton_client/client/tonclient.h
   to
   MacOS:
   /usr/local/include/tonclient.h
   Linux:
   /usr/include/tonclient.h

Setup TONSDK For iOS

0. Install Rust

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh || true && \
source ~/.profile

1. Install "cargo lipo"

rustup target add aarch64-apple-ios x86_64-apple-ios || true && \
cargo install cargo-lipo

2. Build SDK for iOS

Go to your project folder and:

git clone https://github.com/tonlabs/SDK.git || true && \
cd ./SDK

git pull --ff-only || true && \
cargo update || true && \
cargo lipo --release

⚠️ Wait installation

3. In xcode File > Add files to "Name Your Project" navigate to ./SDK/ton_client/tonclient.h

4. Create bridge. In xcode File > New > File, select Header File, set name for example Tonclient-Bridging-Header.h

and add

#include <stdbool.h>

#import "tonclient.h"

like this:

#ifndef Tonclient_Bridging_Header_h
#define Tonclient_Bridging_Header_h

#include <stdbool.h>
#import "tonclient.h"

#endif

5. Add path to Tonclient-Bridging-Header.h $(PROJECT_DIR)/Tonclient-Bridging-Header.h

6. Add path to search for libraries ( path to directory withlibton_client.a ) $(PROJECT_DIR)/SDK/target/universal/release

7. File > Swift Packages > Add Package Dependency https://github.com/nerzh/ton-client-swift

8. Build project ...

Tests

If you use Xcode for Test

Please, set custom working directory to project folder for your xcode scheme. This is necessary for the relative path "./" to this library folders. You may change it with the xcode edit scheme menu Product > Scheme > Edit Scheme menu Run submenu Options enable checkbox "Use custom directory" and add custom working directory.

Or if above variant not available, then inside file path_to_this_library/.swiftpm/xcode/xcshareddata/xcschemes/TonClientSwift.xcscheme set to tag "LaunchAction" absolute path to this library with options:
useCustomWorkingDirectory = "YES"
customWorkingDirectory = "/path_to_this_library"

Tests

1. inside root directory of everscale-client-swift create .env.debug file with NET TON DEV

server_address=https://net.ton.dev
giver_address=0:653b9a6452c7a982c6dc92b2da9eba832ade1c467699ebb3b43dca6d77b780dd
giver_abi_name=Giver
giver_function=grant

Optional: Install locale NodeSE for tests if you needed:

• launch docker
• docker run -d --name local-node -p 80:80 tonlabs/local-node
  nodeSE will start on localhost:80

server_address=http://localhost:80
giver_abi_name=GiverNodeSE_v2
giver_amount=10000000000

2. Run Tests
   MacOS:
   Run Tests inside Xcode
   Linux:
   swift test --generate-linuxmain
   swift test --enable-test-discovery

Update SDK

cd everscale-client-swift

bash api_generate.sh
