Same datatype multiple variable declaration in swift

Question

in objective-c we can declare variable like -NSString *a,*b,*c;

in swift there a way to declare same datatype multiple variable variable rather than doing like below

var a: NSString = ""
var b: NSString = ""
var c: NSString = ""

So, is it possible to declare all a,b,c variable into one line like var (a,b,c): a:NSstring=("","","") or something?

Solution

You can declare multiple constants or multiple variables on a single line, separated by commas:

var a = "", b = "", c = ""

NOTE

If a stored value in your code is not going to change, always declare it as a constant with the let keyword. Use variables only for storing values that need to be able to change.

Type Annotations:

You can define multiple related variables of the same type on a single line, separated by commas, with a single type annotation after the final variable name:

var red, green, blue: Double

NOTE

It is rare that you need to write type annotations in practice. If you provide an initial value for a constant or variable at the point that it is defined, Swift can almost always infer the type to be used for that constant or variable, as described in Type Safety and Type Inference.

I want to initialize var taxableIncome, taxBeforeCess, taxAfterCess: Double this value all at once. What will be syntax? I tried multiple things, but none worked.
