Reading a Swift 910 message in R

Question

I have a data frame with a column including a Swift 910 message encoded as a string. I need to receive and parse the message in R.

Does R have a built-in solution for this? I don't want to reinvent the wheel unless absolutely necessary.

Answer 1

My recommendation would be harness the python Swift parser package via R reticulate. I am not aware of a Swift package for R.

Python Swift Parser

https://github.com/danielquinn/mt103

Usage:

from mt103 import MT103

mt103 = MT103("some-mt-103-string")
print("basic header: {}, bank op code: {}, complete message: {}".format(
    mt103.basic_header,
    mt103.text.bank_operation_code
    mt103
))

Reticulate R package

https://blog.rstudio.com/2018/03/26/reticulate-r-interface-to-python/

install.packages("reticulate")

Usage:

library(reticulate)
mt103 <- import("mt103")
