Swift 3 error: [_SwiftValue pointSize] unrecognized selector sent to instance


If I use your test code, but let the data type of attributes default, it doesn't crash. That is:

let attributes = [NSFontAttributeName: UIFont.systemFont(ofSize: 14)]

Option-clicking on the variable says it's [String : UIFont].

A little extra testing, suggests that it's related to the optional object; [String: AnyObject] appears to work OK.

EDIT:And after all that, I decided to read the documentation, which says to use [String: Any]. :)


The following fixed it for me:

let attributes: [String: UIFont] = [NSFontAttributeName: UIFont.systemFont(ofSize: 14)]


func attributedString(firstText : String, amount : String, fontSize : CGFloat, color : UIColor) -> NSAttributedString {    let attrDict = [ NSFontAttributeName : UIFont(name: fontRegular, size: CGFloat(fontSize/2))!,                    NSForegroundColorAttributeName : UIColor.darkGray] as [String : AnyObject]    let iconString = NSMutableAttributedString(string: firstText, attributes: attrDict)    let attrDict1 = [ NSFontAttributeName : UIFont(name: fontRegular, size: CGFloat(fontSize))!,                     NSForegroundColorAttributeName : color] as [String : AnyObject]    let amountString = NSMutableAttributedString(string: amount, attributes: attrDict1)    iconString.append(amountString)    return iconString}

And call it like

lblBalanceAmount.attributedText = self.attributedString(firstText: "My Balance", amount: "500", fontSize: newFontSize, color : UIColor(red: 41/255.0, green: 192/255.0, blue: 42/255.0, alpha: 1.0))
