String interpolation in swift

String interpolation is just several imagine term for combining variables and constants within a string.

For example a string like so:

var brand = "Apple"

Now we might simply print this out by executing:

print("My favorite brand is \(brand)")

We might also utilize this way:

print("My favorite brand is " + brand)

But this technique isn’t very efficient especially if your combining lots of different data types.

Let’s execute an example with various data types:

var brand = "Apple"

var month = "may"

var day = 1

var year = 1987

print("\(brand) was started on \(month) \(day), \(year)")

Use math

You can simply use math within String Interpolation.

var brand = "Apple"

var month = "may"

var day = 1

var year = 1987

print("\(brand) was started on \(month) \(day * 10), \(year / 5)")
