Copy the html into your project directory and use this code :
@IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
var htmlFile = NSBundle.mainBundle().pathForResource("MyHtmlFile", ofType: "html")
var htmlString = try? String(contentsOfFile: htmlFile!, encoding: NSUTF8StringEncoding)
webView.loadHTMLString(htmlString!, baseURL: nil)
}

I'm quite confused. Where is the exact path defined? I'm a newbie in swift and also in xcode:/ However I cannot figure out... maybe: How to load the file in xcode project to target it this way?

@ Tomas Javurek just drag your file inside the project folder

@RizwanShaikh I did it this way, intuitively. I already have 'default.html' in my xcode project and I try to load it this way
let htmlFile = Bundle.main.path(forResource: "default", ofType: "html"). The file is also a part of compiled bundle and is in Resources folder. But while I try to get the content of file, it produce an error. I tried also print the value of htmlFile, unwrapped, and it returns nil..., so my problem is somewhere else... any idea what I am doing wrong?Tomas Javurek
I figure it out by using this code:
let bundle = Bundle(for: MyView.self) let url = bundle.url(forResource:"default", withExtension:"html") let request = URLRequest(url: url!) self.webView.load(request)

@TomasJavurek, you are my hero. You should add that as an answer.
In Swift 3:
let htmlFile = Bundle.main.path(forResource:"MyHtmlFile", ofType: "html")
let htmlString = try? String(contentsOfFile: htmlFile!, encoding: String.Encoding.utf8)
webView.loadHTMLString(htmlString!, baseURL: nil)
I recommend using optional chaining instead of force unwrapping htmlString as above.

You can write some utility method like this and get the html string and load it to webview. I used the URL approach here
private func getHTML() -> String {
var html = ""
if let htmlPathURL = Bundle.main.url(forResource: "test", withExtension: "html"){
do {
html = try String(contentsOf: htmlPathURL, encoding: .utf8)
} catch {
print("Unable to get the file.")
}
}
return html
}

Swift 3 syntax:
guard
let file = Bundle.main.path(forResource: "agreement", ofType: "html"),
let html = try? String(contentsOfFile: file, encoding: String.Encoding.utf8)
else {
return
}
webView.loadHTMLString(html, baseURL: nil)

Simple answer
let indexPath = Bundle.main.path(forResource: "index", ofType: "html", inDirectory: "/")
if let indexPath = indexPath
{
do
{
let htmlContent = try String(contentsOfFile: indexPath, encoding: String.Encoding.utf8)
let base = Bundle.main.resourceURL
self.webView.loadHTMLString(htmlContent, baseURL: base)
}
catch let err as NSError
{
print(err.debugDescription)
}
}
