Question 66758 in IOS Swift Question posted in
The official documentation can be found here.

Accessing an iOS URL Scheme, at Runtime – Ios swift

This is fairly straightforward.

I have an app that publishes a URL scheme, like so.

In the spirit of DRY, I’d like to avoid referencing it, using constant strings. Instead, I’d like to fetch it from the bundle.

How do I do that?

    This was solved by leveraging Gereon's answer. Here's how I did it:

    /* ###################################################################################################################################### */
// MARK: - Fleshing out the Addressable (General) -
/* ###################################################################################################################################### */
public extension LGV_MeetingSDK_AddressableEntity_Protocol {
    /* ################################################################## */
    /**
     This fetches the first URL scheme from the bundle, renders it as a String, and returns it.
     */
    var urlScheme: String {
        guard let bundleTypes = Bundle.main.infoDictionary?["CFBundleURLTypes"] as? [[String: Any]],
              let myURLScheme = (bundleTypes.first?["CFBundleURLSchemes"] as? [String])?.first
        else { return "" }

        return myURLScheme
    }
}

/* ###################################################################################################################################### */
// MARK: - Fleshing out the Addressable (User) -
/* ###################################################################################################################################### */
public extension HeartOfRecovrr_Member {
    /* ################################################################## */
    /**
     This returns an addressable URL for this member record.
     */
    var urlString: String { "(urlScheme)://user/(id)" }
}

    And here it is, in my general-purpose Swift extensions package.

    This snippet prints the URL schemes defined in an app’s Info.plist:

    if let types = Bundle.main.infoDictionary?["CFBundleURLTypes"] as? [[String: Any]] {
    var result = [String]()
    for type in types {
        guard let schemes = type["CFBundleURLSchemes"] as? [String] else { continue }
        guard let scheme = schemes.first else { continue }
        result.append(scheme)
    }
    print(result)
}
