NSLocalizedString runtime error on Swift 3

Question

I'm developing an app with Swift and SpriteKit. I've converted my code from Swift 2.3 to Swift 3, but when I run the code I get the following error:

Thread 1:EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP.subcode=0x0)

The error show up on this line. I've created okLabel with SKLabelNode.

okLabel.fontName = (text: NSLocalizedString("dialogOKFont", comment: "")) as! String

On Localizable.strings(Base), I've defined "dialogOKFont" as follows:

"dialogOKFont" = "Optima-Bold";

I really appreciate if someone gives me an answer or hint to fix this error. Thank you in advance.

It looks like you're casting to a string outside of the parenthetical s for your font. Also, check out this extension http://stackoverflow.com/questions/25081757/whats-nslocalizedstring-equivalent-in-swift — TheValyreanGroup, May 07 '17 at 13:45
Paulo Mattos' answer explains the problem. But do you really want to use NSLocalizedString to get a font name? — gnasher729, May 07 '17 at 14:28

Try this instead:

okLabel.fontName = NSLocalizedString("dialogOKFont", comment: "")

Your original code had two related mistakes:

you wrapped the localized string in single element tuple: (text: ...)
and then you casted this tuple back to String, resulting in the EXC_BAD_INSTRUCTION crash

Using only NSLocalizedString(...) is enough to get the localized String you were after :)
