FortranFile

Read data from files using a Fortran format specification.

Fortran is great, isn't it? But do you have lots of data sitting in Fortran-formatted files that you would like to access using Swift for your own nefarious purposes? Yes, I thought so. All of the boilerplate you need is here.

How to access a Fortran formatted file.

Step 1. Create a format.

let format = try FortranFile.format(string: "1x,4i1,i5,12i3,f15.11,2f18.11,f14.11,f20.11")

Step 2. Use the format to read a line of input.

let result = try FortranFile.read(input: input, using: format)

The result is an array of any FortranValue corresponding to the values read from the input.
