Answer 1

You can view PDF in iOS 8 by using webview. Try below code,
if let pdf = NSBundle.mainBundle().URLForResource("myPDF", withExtension: "pdf", subdirectory: nil, localization: nil) {
let req = NSURLRequest(URL: pdf)
let webView = UIWebView(frame: CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height))
webView.loadRequest(req)
self.view.addSubview(webView)
}
OR
if let baseUrl = NSURL.fileURLWithPath(pathURL) {
let fileURL = baseUrl.URLByAppendingPathComponent(NFConstants.NFCoreDataStringIdentifiers.CoreDataStoresPathComponent.rawValue)
}
Hope this will be helpful to you.

UIDocumentInteractionController is available with (iOS 3.2, *).
For Viewing PDF file:
var documentInteractionController: UIDocumentInteractionController!
#IBAction func openDocument(sender: UIButton) {
let URL: NSURL = NSBundle.mainBundle().URLForResource("pdf-sample", withExtension: "pdf")!
if (URL != "") {
// Initialize Document Interaction Controller
self.documentInteractionController = UIDocumentInteractionController(URL: URL)
// Configure Document Interaction Controller
self.documentInteractionController.delegate = self
// Present Open In Menu
self.documentInteractionController.presentOptionsMenuFromRect(sender.frame, inView: self.view, animated: true)
//presentOpenInMenuFromRect(button.frame, inView: self.view, animated: true)
}
}
// MARK: UIDocumentInteractionControllerDelegate
func documentInteractionControllerViewControllerForPreview(controller: UIDocumentInteractionController) -> UIViewController {
return self
}
