var is a keyword which stands for "variable." Its type can be inferred or explicitly declared.

For example, the following is explicitly declared to be of type String:

var myString: String = "I am a explicitly typed String."

... while the following is inferred to be of type String:

var myString = "I am an inferred type String."
