To push the user to the iTunes store for desired items I'm using the following function:
func openStoreProductWithiTunesItemIdentifier(identifier: String) { let storeViewController = SKStoreProductViewController() storeViewController.delegate = self let parameters = [ SKStoreProductParameterITunesItemIdentifier : identifier, SKStoreProductParameterAffiliateToken : ITUNES_AFFILIATE_ID] storeViewController.loadProductWithParameters(parameters) { [weak self] (loaded, error) -> Void in if loaded { self!.navigationController?.pushViewControllerWithHandler(storeViewController, animated: true) { LilithProgressHUD.hide() // custom progress hud } } } } extension UINavigationController { func pushViewControllerWithHandler(viewController: UIViewController, animated: Bool, completion: Void -> Void) { CATransaction.begin() CATransaction.setCompletionBlock(completion) pushViewController(viewController, animated: animated) CATransaction.commit() } } Called by
let trackID = "thisIsMyTrackID" openStoreProductWithiTunesItemIdentifier(trackID) This results in
If I'm instead of:
self!.navigationController?.pushViewControllerWithHandler(storeViewController, animated: true) { LilithProgressHUD.hide() // custom progress hud } Using:
self?.presentViewController(storeViewController, animated: true, completion: { LilithProgressHUD.hide() // custom progress hud }) , it is working. But I need the controller to push within the navigationController to fit the rest of the views and animations. What am I missing? Help is very appreciated.

The exception and stack trace tell you that the store view controller isn't happy about being pushed into a nav stack. Your test shows it is happy being presented. From the documentation:
present the view controller modally from another view controller in your app
So, you should present it modally.
While it's possible that you could perhaps make it work in some other way it's likely to break in the future if you don't follow the (inconvenient) guidelines.
