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)

            }

        }
