variable differently from the way Pasan did it. In the video, the code looks like this:
let street = "West Street"
let buildingNumber = 222
let streetAddress = buildingNumber + street
This code does not compile because street
and buildingAddress
are different types. Basically you have text and a number and Swift doesn't know how those should be added together.
My guess is that when you created the buildingNumber
constant, you placed quotes around the number:
let buildingNumber = "222"
This would make it so the street
and buildingNumber
values can be added together because the buildingNumber
is a String
instead of a number.
Hope that sorts it out for you!
