Listing 2.7 Giving population a value

Swift Programming: The Big Nerd Ranch Guide (2nd E 2. Types, Constants, and Variables
1

Hello everyone,

My name is Jessica and I am embarking on a Swift journey and am using Swift Programming: The Big Nerd Ranch Guide 2nd. edition with Xcode 10.

The book code snippet is as follows:
var population: Int
population = 5422

Xcode 10 insists of declaring the value when the variable is defined:
var population: Int = 5422

Just wanna share the changes between the book and Xcode 10

Best Regards,
Jessica

It probably got mangled during the printing process (assuming that you are not reading an eBook.)

I am reading the hard copy. Initially, I wanted to wait for the new edition but the local bookstore was having a 20% off, storewide and I have to pick up Swift. So, I decided not to wait. If you ever need someone to proof-read the new edition, I can do it :=)
