"Nsurl" Is Not Implicitly Convertible to "Url"; Did You Mean to Use "As" to Explicitly Convert

NSURL is not implicitly convertible to URL ; did you mean to use as to explicitly convert?

In swift 3 you need to use URL instead of NSURL, so create url object like this.

if let url = URL(string: "https://www.google.com") {
    webView.load(URLRequest(url: url))
}

“NSURL” is not implicitly convertible to “URL”; did you mean to use “as” to explicitly convert? in swift 3

In swift 3.0, the method signature for openURL is:

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {

            return FBSDKApplicationDelegate.sharedInstance().application(applic‌​ation, open: url, sourceApplication: sourceApplication, annotation: annotation)
    }

In method signature, NSURL is changed to URL.

Is swift 3 not compatible with NSURL classes on iOS 9?

Thanks to OOPer i can answer my own question:

the code works fine with the URL class but only when you set the Deplyoment Target to the same iOS Version as your simulator!

XCode 8 updated my iOS 9 SDK to version 10 and so I only had the choice to use the simulator on either iOS 10 or iOS 8.1. However the Deployment Target was set to iOS 9 (I was pretty sure that it was before the upgrade set to iOS 8.1).

So I run into the runtime error with an iOS 8.1 simulator and Deployment Target set to iOS 9.

But it does work with iOS 8.1 simulator and Deployment Target set to iOS 8.1!

Here is the Swift 3 Code working also with iOS 8.1:

class ServerCom: NSObject, URLSessionDownloadDelegate {

fileprivate var localFileURL: URL = URL(string: "dummy")!

 [...]

         guard let urlString: URL =
            URL(string: params,
                relativeTo: URL(string: dcParam.baseURL) )  else {
                    let failed = "Could not generate URL from: \(dcParam.baseURL)\(params)"
                    throw fetchAppXmlError.failed_URL_GENERATION(failed)
        }

        var request = URLRequest(url: urlString)
        request.timeoutInterval = 10
        request.httpMethod = "GET"
 [...]

}

Thank you!

NSMutableSet' is not implicitly convertible to 'Set NSObject '

You should use native Swift types rather than Foundation collections when possible. This eliminates the need for casting.

var xAxisLabels = Set<CPTAxisLabel>()
var xMajorTickLocations = Set<NSNumber>()

Swift 3 WebView

For this exact situation, retype your line to:

yourWebView.loadRequest(URLRequest(url: URL(string: "http://hardwirestudios.com")!))

... and rename yourWebView variable to one, that you actually use.

In Swift 3.0, use URL and URLRequest as almost all the NS were dropped.

Swift 3 WKWebView 'URLRequest'; did you mean to use 'as' to explicitly convert? ( BUG )

Use URL and URLRequest instead:

let url = URL(string: "https://facebook.com")!
webView.load(URLRequest(url: url))

This is quite similar to https://stackoverflow.com/a/37812485/2227743: you either use NSURL and have to downcast it as URL, or you directly use the new Swift 3 structs.

If you follow the error message, your example would become:

let url = NSURL(string: "https://facebook.com")!
webView.load(URLRequest(url: url as URL))

It could be even worse:

let url = NSURL(string: "https://facebook.com")!
webView.load(NSURLRequest(url: url as URL) as URLRequest)

All this works but of course it's much better to start using URL and URLRequest in Swift 3, without using all this downcasting.
