NSButton extension that adds a method to change its text color.

NSButton+TextColor.swift

import AppKit

extension NSButton {

    func set(textColor color: NSColor) {
        let newAttributedTitle = NSMutableAttributedString(attributedString: attributedTitle)
        let range = NSRange(location: 0, length: attributedTitle.length)

        newAttributedTitle.addAttributes([
            .foregroundColor: color,
        ], range: range)

        attributedTitle = newAttributedTitle
    }
}

It works great, but not on macOS 10.15. Do you have any clue?

Hey @pjkoning.

You might want to try something like this:

let color: NSColor = NSColor.white
if #available(macOS 10.14, *) {
     self.contentTintColor = color
} else {
      // Fallback on earlier versions
      self.set(textColor: color)
}
