I'm using ZSWTappableLabel and ZSWTaggedString to show links inside a label.

import ZSWTappableLabel
import ZSWTaggedString

The pod versions are:

 pod 'ZSWTappableLabel', '~> 2.0'
 pod 'ZSWTaggedString/Swift', '~> 4.0'

The links used to appear in white (same color as the label) by default earlier, but after some update that happened recently (possibly a pod update or xcode version, I'm not able to pinpoint exactly what), the links have started to appear in blue. Setting NSAttributedStringKey.foregroundColor to white doesn't seem to affect anything. NSAttributedStringKey.backgroundColor does affect it, but for some reason the foregroundColor doesn't seem to have any effect.

How can I set the links in white color?

func setTermsAndPrivacyLinkLabel()
 termsAndPrivacyLabel.tapDelegate = self

 let options = ZSWTaggedStringOptions()
 options["link"] = .dynamic( tagName, tagAttributes, stringAttributes in
 guard let type = tagAttributes["type"] as? String else 
 return [NSAttributedStringKey : Any]()
 

 var foundURL: NSURL?

 switch type 
 case "privacy":
 foundURL = NSURL(string: "(privacyUrl)")!
 case "tos":
 foundURL = NSURL(string: "(termsUrl)")!
 default:
 break
 

 guard let URL = foundURL else 
 return [NSAttributedStringKey : Any]()
 

 return [
 .tappableRegion: true,
 NSAttributedStringKey.foregroundColor: UIColor.white,
 NSAttributedStringKey.font: UIFont.boldSystemFont(ofSize: 13.0),
 .link: foundURL
 ]
 )

 let string = NSLocalizedString("By logging in, you agree to our <link type='tos'>terms</link> and <link type='privacy'>privacy</link>.", comment: "")
 termsAndPrivacyLabel.attributedText = try? ZSWTaggedString(string: string).attributedString(with: options)


func tappableLabel(_ tappableLabel: ZSWTappableLabel, tappedAt idx: Int, withAttributes attributes: [NSAttributedStringKey : Any] = [:]) 
 guard let url = attributes[.link] as? URL else 
 return
 

 UIApplication.shared.openURL(url)

This works:

 extension HomeViewController: ZSWTappableLabelTapDelegate {
 static let urlAttributeName = NSAttributedStringKey(rawValue: "URL")

 func setLinks()
 termsPrivacyLabel.tapDelegate = self

 enum LinkType: String 
 case privacy = "privacy"
 case terms = "terms"

 var URL: Foundation.URL 
 switch self 
 case .privacy:
 return Foundation.URL(string: "myprivacyurl")!
 case .terms:
 return Foundation.URL(string: "mytermsurl")!
 
 
 

 let options = ZSWTaggedStringOptions()
 options["link"] = .dynamic( tagName, tagAttributes, stringAttributes in
 guard let typeString = tagAttributes["type"] as? String,
 let type = LinkType(rawValue: typeString) else 
 return [NSAttributedStringKey: AnyObject]()
 

 return [
 .tappableRegion: true,
 .tappableHighlightedForegroundColor: UIColor.white,
 .foregroundColor: UIColor.lightGray,
 .underlineStyle: NSUnderlineStyle.styleNone.rawValue,
 .font: UIFont.boldSystemFont(ofSize: 13.0),
 HomeViewController.urlAttributeName: type.URL
 ]
 )

 let string = NSLocalizedString("By signing in, you agree to the <link type='terms'>terms</link> and <link type='privacy'>privacy</link>.", comment: "")
 termsPrivacyLabel.attributedText = try? ZSWTaggedString(string: string).attributedString(with: options)
 

 func tappableLabel(_ tappableLabel: ZSWTappableLabel, tappedAt idx: Int, withAttributes attributes: [NSAttributedStringKey : Any] = [:]) 
 guard let URL = attributes[HomeViewController.urlAttributeName] as? URL else 
 return
 

 if #available(iOS 9, *) 
 show(SFSafariViewController(url: URL), sender: self)
 else 
 UIApplication.shared.openURL(URL)
