Can't get Typhoon to work in Swift project

[alexmaie]

Hey guys,

I have the following class

public class HuntConfiguration: NSObject {

    public var tasks =  [ParticipantTaskGroup]();

    var configurationSource : ConfigurationSourceProtocol;

    public init(Configsource: ConfigurationSourceProtocol ) {

        configurationSource = Configsource;

        var result = configurationSource.getTaskGroups();

        switch(result){
        case .Success(let t ):
            tasks = t;
        case .Failure:
          ExceptionBridge.throwExceptionWithString("No configuration loaded")
        }
    }
}

and Assembly

public class ApplicationAssembly: TyphoonAssembly {


    public dynamic func configuration() -> AnyObject{
        return TyphoonDefinition.withClass(HuntConfiguration.self){
            (definition) in

            definition.useInitializer("initWithConfigsource:") {
                (initializer) in

                initializer.injectParameterWith(FileConfigurationSource());
            }

           definition.scope = TyphoonScope.Singleton;
        }
    }


}

Now, if i want to resolve the HuntConfiguration class

    let assembly = ApplicationAssembly().activate()
    var config = assembly.configuration() as? HuntConfiguration;

I get an exception in method

- (BOOL)isClassMethodOnClass:(Class)_class
{
    BOOL instanceRespondsToSelector = [_class instancesRespondToSelector:_selector];
    BOOL classRespondsToSelector = [_class respondsToSelector:_selector];

    if (!instanceRespondsToSelector && !classRespondsToSelector) {
        [NSException raise:NSInvalidArgumentException
                    format:@"Method '%@' not found on '%@'. Did you include the required ':' characters to signify arguments?",
         NSStringFromSelector(_selector), NSStringFromClass(_class)];
    }

    return classRespondsToSelector && !instanceRespondsToSelector;
}

I don't know how to solve the problem

Hi @alexmaie ! Sorry for the delay in reply. The best place to ask general questions is StackOverflow - usually gets a faster response.

Can you post the actual error that was thrown?

[alexmaie]

Yo @jasperblues

This is the error

Be sure to mark the initializer as dynamic otherwise Swift will optimize it in a way that it can't be invoked via the ObjC runtime:

public dynamic init(Configsource: ConfigurationSourceProtocol ) 

[jasperblues]

@alexmaie Let's move this question over to StackOverflow. It look like a config issue, however if we discover a bug, we can open one here.

Hey Jasper

SOrry for my late response, but I had to work on another project and couldnt test out the dynamic addition. Because of Protocol ConfigurationSourceProtocol, that was using an generic enum, I could not get the project to compile. I had to remove the generic enum and afterwards everything worked fine :)

@alexmaie Glad to hear its working now. . yes, Typhoon is a little more tricky with Swift, but at least the syntax in Swift is nice to look at :)

[alexmaie]

I agree :) . Would have hoped to come up with a better error handling
mechanism then passing around NSError or Enums. It's a pity that Exceptions
can't be used :(
