[SWIFT] Countermeasures for forgetting to specify the font when titleTextAttributes is specified

Overview

When I specified titleTextAttributes to change the text color of the iOS navigation bar, the font was broken, so I coped with it.

environment

Xcode 11.3 iOS 14.0 & 13.3

Event

If the font is specified in the navigation bar title, Even if only the color is specified, the font specification is not specified.

--If the font is Hiragino Kaku Gothic (with xib)

--If you want to change the color of the title on a specific screen and specify only the color as is often the case, the font specification will be removed (is it the system default?)

    self.navigationController?.navigationBar.titleTextAttributes = [
    　　//Text color
       .foregroundColor: UIColor.yellow
    ]

Countermeasures

--You also need to add the font specification

    self.navigationController?.navigationBar.titleTextAttributes = [
        NSAttributedString.Key.foregroundColor: UIColor.yellow,
        NSAttributedString.Key.font: UIFont(name: "HiraginoSans-W3", size: 16) as Any
    ]

It's natural, but I didn't notice it, so I'll post it as a memorandum.
