I went to use UIWebView to display dynamic content, instead of doing it natively using UI-elements. Is it possible to trigger native app functions from simply hitting links inside the UIWebView? Example: hitting a link which then switches current View?

Unlike UIWebView, which does not support server authentication challenges, WKWebView does. In practical terms, this means that when using WKWebView, you can enter site credentials for password-protected websites.
A view that embeds web content in your app.
You can think of WKWebView as a stripped-down version of Safari. It is responsible to load a URL request and display the web content. WKWebView has the benefit of the Nitro JavaScript engine and offers more features. If you just need to display a specific web page, WKWebView is the best option for this scenario.
WKWebView is an API that helps render web pages in iOS and macOS apps.
The WKWebView is a modern API applying all the modern web security mechanisms, it's still maintained by Apple and gets updates. The good thing about WKWebView is that it does out-of-process rendering, so if the attackers find a memory corruption vulnerability in it, your application's process is still isolated.
WebView can be defined as an object which can display the interactive web content and load HTML strings within the iOS application for an in-app browser. It is an instance of the WKWebView class, which inherits the UIView class.
Yes, it's possible. In your html, you write a JS to load a URL with a fake scheme such as
window.location = "request_for_action://anything/that/is/a/valid/url/can/go/here";
Then, in your iOS code, assign a delegate to your webView, and in your delegate, handle
webView:shouldLoadWithRequest:navigationType
with something like
if( [request.URL.scheme isEqualToString: @"request_for_action"] )
{
// parse your custom URL to extract parameter, use URL parts or query string as you like
return NO; // return NO, so webView won't actually try to load this fake request
}

Just an aside, you can do the other way, let iOS code invoke some JS codes in your html by using
NSString* returnValue = [self.webView stringByEvaluatingJavaScriptFromString: "someJSFunction()"];
