Not quite, amount: "500.00" this is incorrect. "500.00" is a String, not a Double.

You are inserting a string instead of a double for the initializer.


var travel = Expense(description: "Flight to Cupertino", amount: "500.00")


var travel = Expense(description: "Flight to Cupertino", amount: 500.00)
