1. With a magnet.
2. OR, add H2O, NaCl dissolves, filter to remove the iron (not soluble in water), then evaporate the water to recover the NaCl.

Through magnetism, because it's a mixture of a magnetic substance (iron fillings)and a non-magnetic substance (NaCl sln), Evaporation is only used to separate a mixture of a liquid (for example water) and a soluble solid substance (e.g. NaCl)

You are correct, evaporation cannot be used to separate the mixture of iron filings and sodium chloride. Using a magnet is the most efficient method to separate these two substances since iron filings are magnetic but sodium chloride is not. The mixture can be placed in a container, and a magnet can be passed over it to attract the iron filings, leaving behind the sodium chloride.
