How?

Sounds like homework.

What makes the Na+ and Cl- come apart?

It ain’t. 
The interaction of water molecules.

[Bufofrog]

What kind of interaction?  You do know you can Google the answer in about 5 seconds?

New (chemical) species are formed.

I did. Some people are saying that its a physical change and some are saying that it is a chemical change.

In a solution the constituents exhibit individual chemical characteristics. You are saying that new chemical species are formed. So will the "NaCl in water " solution have different chemical properties from its constituents(NaCl and H2O)? i.e. is a "NaCl in water" solution a new compound with respect to NaCl or H2O ? And is the ion surrounded by water molecules (solvation shell) a new compound?

Dissolving salt in water changes the NMR spectrum of the protons in the water molecules.

That's evidence of a chemical reaction.

It's a chemical change, the ionic bonds are broken by the water.

Rather than entering into another long pointless argument about the defintion, here is the first page of a modern textbook all about what are chemical reactions and why they occur.

There is a whole chapter about solvation.
