Swift and scriptingbridge object initialization

Question

I\'m trying to write an application for swift control iTunes. But when initializing the application returns an object of type AnyObject, but must iTunesApplication.

Answer 1

In my swift project , I had issues with using the types defined in the generated iTunes.h file (linking errors and such).

The answer from markhunte explains that you can obtain a reference to the application object. But beyond that, I was getting compilation/linker errors when trying to obtain instances from that application object.

In my swift project, I ended up creating an objective C wrapper class that exposes the iTunes types as basic objective C types (arrays and dictionary), and adapts methods as well.

My swift classes use this wrapper instead of the iTunes types.

So, the objective C wrapper looks like this (redux):

#import "ITunesBridgex.h"
#import "iTunes.h"

@interface ITunesBridgex(){
    iTunesApplication *_iTunesApplication;
    iTunesSource* _iTunesLibrary;
}
@end
@implementation ITunesBridgex

-(id)init {
    self = [super init];
    if (self) {
        _iTunesApplication = [SBApplication applicationWithBundleIdentifier:@"com.apple.iTunes"];
        NSArray *sources = [_iTunesApplication sources];
        for (iTunesSource *source in sources) {
            if ([source kind] == iTunesESrcLibrary) {
                _iTunesLibrary = source;
                break;
            }
        }
    }
    return self;
}

- (NSDictionary*) currentTrack {
    iTunesTrack* track = _iTunesApplication.currentTrack;
    if (!track)
        return nil;
    NSDictionary* dict = [NSDictionary dictionaryWithObjectsAndKeys: track.name, @"title", nil];
    return dict;
}

@end

and the calling swift code:

import Foundation
import Cocoa

class ITunesBridgeSimple {

    var iTunesBridgex: ITunesBridgex

    init(){
        iTunesBridgex = ITunesBridgex()
        self.updateFromCurrentTrack()
    }
    func updateFromCurrentTrack() {
        if let track = self.currentTrack {
            if let title : AnyObject = track.objectForKey("title"){
                println("Current track: \(title)")
            }
        }
    }
}
