Swift pdf attachment in Mail - swift

Question

In my code
class DocViewController: UIViewController,UITextViewDelegate, MFMailComposeViewControllerDelegate{
var result:String!
override func viewDidLoad() {
super.viewDidLoad()
result = "/Test - " + dateToday!
func getPDFFileName(_ name: String) -> String {
let newPDFName = "\(name).pdf"
let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
let documentsDirectory = paths[0]
let pdfFileName: String = (documentsDirectory as String).appending(newPDFName);
print(pdfFileName)
return pdfFileName
}
#IBAction func sendMail(_ sender: UIBarButtonItem) {
let mailComposeViewController = configuredMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
self.present(mailComposeViewController, animated: true, completion: nil)
} else {
self.showSendMailErrorAlert()
}
}
func configuredMailComposeViewController() -> MFMailComposeViewController {
let mailComposer:MFMailComposeViewController = MFMailComposeViewController()
mailComposer.mailComposeDelegate = self
let recipients = ["a#a.com"]
//Set the subject and message of the email
mailComposer.setToRecipients(recipients)
mailComposer.setSubject("Test")
mailComposer.setMessageBody("Send Saved PDF File", isHTML: false)
if let filePath = Bundle.main.path(forResource: getPDFFileName(result), ofType: "pdf") {
print("File path loaded.")
if let fileData = NSData(contentsOfFile: filePath) {
print("File data loaded.")
mailComposer.addAttachmentData(fileData as Data, mimeType: "application/pdf", fileName: "pdf")
}
present(mailComposer, animated: true, completion: nil)
}
return mailComposer
}
I am creating pdf and would like to send through mail. Mail works. But the pdf is not attached. If I use simulator the directory is /Users/xxxxxx/Library/Developer/CoreSimulator/Devices/91BD76E3-7BD6-49E9-87E7-63C87BE980EF/data/Containers/Data/Application/16350B51-6898-45AA-BEF3-F0B0E4FF7556/Documents/Test - Monday, 25 December 2017.pdf
if I use iPhone, the save directory is:
/var/mobile/Containers/Data/Application/7374E0A1-3E49-494D-B554-1D9C761FC7C1/Documents/Test - Monday, 25 December 2017.pdf and the console message is 2017-12-25 20:36:45.344149+0530 Karma[7690:1157301] [App] if we're in the real pre-commit handler we can't actually add any new fences due to CA restriction when I try to attach mail. Where am I doing wrong? How to specify the same location for the iPhone to attache the created pdf file? Please help.
EDIT:
Below code works and attaching the created pdf with mail:
class DocViewController: UIViewController,UITextViewDelegate, MFMailComposeViewControllerDelegate{
var result:String!
override func viewDidLoad() {
super.viewDidLoad()
result = "/Test - " + dateToday!
func getPDFFileName(_ name: String) -> String {
let newPDFName = "\(name).pdf"
let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
let documentsDirectory = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)[0] as! String
let pdfFileName: String = (documentsDirectory as String).appending(newPDFName);
print(pdfFileName)
return pdfFileName
}
#IBAction func sendMail(_ sender: UIBarButtonItem) {
let mailComposeViewController = configuredMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
present(mailComposeViewController, animated: true, completion: nil)
} else {
self.showSendMailErrorAlert()
}
}
func configuredMailComposeViewController() -> MFMailComposeViewController {
let mailComposer:MFMailComposeViewController = MFMailComposeViewController()
mailComposer.mailComposeDelegate = self
let recipients = ["a#a.com"]
//Set the subject and message of the email
mailComposer.setToRecipients(recipients)
mailComposer.setSubject("Test")
mailComposer.setMessageBody("Send Saved PDF File", isHTML: false)
let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)[0] as! String
let filePath = getPDFFileName(result)
print("File path loaded.")
if let fileData = NSData(contentsOfFile: filePath) {
print("File data loaded.")
mailComposer.addAttachmentData(fileData as Data, mimeType: "application/pdf", fileName: result)
self.present(mailComposer, animated: true, completion: nil)
}
return mailComposer
}
}

Swift 4.0
try this
let mailComposer = MFMailComposeViewController()
mailComposer.mailComposeDelegate = self
//Set to recipients
mailComposer.setToRecipients(["your email address heres"])
//Set the subject
mailComposer.setSubject("email with document pdf")
//set mail body
mailComposer.setMessageBody("This is what they sound like.", isHTML: true)
if let filePath = Bundle.main.path(forResource: "All_about_tax", ofType: "pdf")
{
print("File path loaded.")
if let fileData = NSData(contentsOfFile: filePath)
{
print("File data loaded.")
mailComposer.addAttachmentData(fileData, mimeType: "application/pdf", fileName: "All_about_tax.pdf")
}
}
//this will compose and present mail to user
self.present(mailComposer, animated: true, completion: nil)
