How to parse the return value of read transaction

[DarcyLau]

Here is the return value of the transaction, but how can I parse it into Double or BigUInt

result: Optional(["0": 0])

and the abi file says the return value is UInt256

[dangell7]

import BigInt
let result = try? tokenBalanceTx?.call()
guard let tokenWei = result?["0"] as? BigUInt else {
    print("FAILED ON PARSE RESULT")
    return nil
}
