Concatenation is to link together two objects of any sort. Let’s say we would like to concatenate A & B, it just means we would like to link A & B together and the output would be A B. In Swift, there are many different ways to concatenate two objects. Some of follow example are as follow:
let a = "a" let b = "b" let output = a + b // ab let output1 = "A: \(a) " + "B: \(b)" // A: a B: b
There are time that you would like to concatenate a data with a description and you could use the output1 or in times you only would like to concatenate the data, then you could use output
