You have an old example of using lib Now we get the name of token now we used ->
Go to https://infura.io/dashboard/ethereum
Create a new project. In new project you will have PROJECT ID

guard let url = URL(string: "https://kovan.infura.io/v3/your PROJECT ID"), let web3 = try? Web3.new(url) else { return } let w3sTokenAddress = EthereumAddress("")! let st20token = ERC20.init(web3: web3, provider: web3.provider, address: w3sTokenAddress)
