MFMailComposeViewController not showing Cancel button - swift

Question

I tried all the SOF solutions nothing work for my case.
My app is using tabbar and one of the tabbar is setting(tableview). User can tap on the support cell to send email.
I can bring up the email view but it doesn't have cancel button. Only way to dismiss it is to send the email or swipe down save/delete draft.
Thanks!!

Issue solved. I was setting the navigation bar color in app delegate so it makes the text white color as well.
