ContractSwift

Fully typed, autocompleted Ethereum Smart Contract in Swift

Features

• Generates Contract.generated.swift file from ABI
• All of your smart contract functions are fully typed and autocompleted
• Get data parameter string of transaction
• Multiple contracts are available

Demo

How to get transaction data parameter:

    Contract
        .Abi1
        .Function
        .transfer(Address(string: "0x5c66b0d82df26e8FE165Be6628F5f5e1f1bccD5C"), BInt("100000000000000")!)
        .txDataString()

    // => 0xa9059cbb0000000000000000000000005c66b0d82df26e8FE165Be6628F5f5e1f1bccD5C00000000000000000000000000000000000000000000000000005af3107a4000

Solidity type conversion

Currently supports:

• bool => Bool
• int8<16,32,64,128,256> => BInt
• uint8<16,32,64,128,256> => BInt
• address => Address
• string => String
• bytes => Data
• bytes1<2,4,8,16,32> => Data

Installation

Currently supports CocoaPods.

Basically, ContractSwift needs ABI json files in specific directory.

- $SRCROOT
    - abi
        - Contract1.json
        - Contract2.json
        - ...

Name of json file will be its contract name in swift.

struct Contract {
    struct Contract1 {
        ...
    }
}
// => Contract.Contract1.Function.transfer...

1. Add pod 'ContractSwift' to your Podfile and run pod install
2. Add a New Run Script Phase in Xcode.
3. Paste the folowwing script(first argument is an input directory, second is output):

"$PODS_ROOT/ContractSwift/contractswift" generate "$SRCROOT/abi" "$SRCROOT"

4. Build your project, then you'll see Contract.generated.swift file in the $SRCROOT directory.
5. Add Contract.generated.swift into your project.
