String Concatenation is letting me compile building number & the Street! Is it a bug or a new feature?
let streetAddress = buildingNumber + street Result: "222Khalidia Street"

My guess is that you declared the
buildingNumber 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
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
buildingNumber values can be added together because the
buildingNumber is a
String instead of a number.
Hope that sorts it out for you!
