iOS: Loading a WKWebView with a web URL

WKWebViewURL.swift

/* Load given URL into web view */

/* Note: For http:, need to setup App Transport Settings to allow:
    Key: App Transport Security Settings
    Subkey: Allow Arbitrary Loads to YES
    
    Produces:
    
    <key>NSAppTransportSecurity</key>
    <dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    </dict>
    
    This allows any URL, but is NOT good practice.
    Should only allow specific URLS (Exception Domains
