How do you do println() in swift 2

Question

I cant seem to find out how to do println() in Swift 2.

I tried doing println(helloworld)

That doesn't work

helloworld is a variable

print and println function has been merged to a single method in Swift2. It is available in Xcode7 beta. — Amit89, Jul 04 '15 at 04:57
If you type `println("Hello world")` in Xcode 7, the error message *"'println' has been renamed to print"* immediately pops up, together with a *"Fix it: replace 'println' by 'print'"* suggestion. — Martin R, Jul 04 '15 at 09:20

No More println() As per apple documentation :

In Swift 2.0 there is

print("Hello")

for the new line you can set flag

print("Hello", appendNewline: false)

Declaration

func print(_ value: T, appendNewline appendNewline: Bool)

Discussion

The textual representation is obtained from the value using its protocol conformances, in the following order of preference: Streamable, CustomStringConvertible, CustomDebugStringConvertible. If none of these conformances are found, a default text representation is constructed in an implementation-defined way, based on the type kind and structure.

Is it just me, or does it require "Swift.print()" sometimes? It literally opens up printing options. Xcode 7.1 Beta 2. – Naoto Ida Oct 04 '15 at 23:43
If you are building OS X Applications you'll need to do swift.print(...) - print(...) is for the printer dialog box. – Morten Gustafsson Feb 27 '16 at 07:22
@MortenGustafsson Thanks for information. But question is of iOS not OS X. – Ashish Kakkad Feb 27 '16 at 10:03
@AshishKakkad I Know, I was answering Naoto Ida's comment. :) Sorry for not clarifying that. – Morten Gustafsson Feb 29 '16 at 08:52
@MortenGustafsson It's Ok. :) – Ashish Kakkad Feb 29 '16 at 09:00

it's print("hello world"). it's changed in swift 2.0 and you need to see Apple's website. put print() instead of println()

print(hello world) won't work. :) It should be print(hello, world) if hello and world are variables. Or print(helloworld) if helloworld is a variable. – Morten Gustafsson Feb 27 '16 at 07:12

Use quotation marks:

println("helloworld")

and in swift 2.0, use print():

print("helloworld")
