increment Error in swift 3

Question

Hello I am using swift and when I am trying to use and increment it outputs a pair of parenthesis.

var initialScore = 8
let TotalScore = initialScore+=1

The error comes out as

Constant 'TotalScore' inferred to have type '()', which may be unexpected

Please help me!

It's *either* `let TotalScore = initialScore + 1`... or just `initialScore += 1` *then* `let TotalScore = initialScore`. It doesn't do the same thing, be careful. — Eric Aya, Sep 26 '16 at 14:04
More or less the same issue as in http://stackoverflow.com/questions/26155523/multiple-variable-assignment-in-swift: the assignment operators in Swift do not return a value. — Martin R, Sep 26 '16 at 14:07

You have small issue that is connected with =. To solve youre problem try :

var initialScore = 8
let TotalScore = initialScore+1

If you would like to increment value by 1 you should not use = before 1 in you're case.

Small example where you should use += together.

var a = 1
a += 2
