Description:

I have a project which is mostly Objective C, but I am trying to do new work in Swift where possible.

I am adding an integration with Fitbit.

I have created a class in Swift to handle all the business logic, but I am looking to deal with the URL handler in AppDelegate which is an Objective C file.

I am not able to get the correct syntax for this.

The code (and this template!) implies support for Objective C, but a worked example for this would be hugely appreciated

Tried:

@import OAuthSwift;

 // ...

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {

    if ([url.host isEqualToString: @"oauth-callback"]) {
        [OAuthSwift handleUrl:url];
        return true;
    }
}

Gets compile error:

No known class method for selector handleUrl

maybe try with swift 3.2 because I do not try objc since swift 4

I make some methods prefixed with objc_ to handle some compatibility issue with objective c
in Sources/Objc.swift
I think maybe some annotations must be added, like @objc, and maybe some methods are missing

Ok thanks :)

As a work around I added a pass through method to my custom class:

@objc func handle(url: URL) {
    OAuthSwift.handle(url: url)
}

Which I can call from Objective C. If I am not missing something obvious I will leave this in place for now.

I know this is an old issue, but I am also having this problem.
I am using 1.4.1 as suggested by the readme, but it seems OAuthSwift.handle(url: url) is not exposed to objc
