How do I Generate a Text Message to a Predefined Phone Number in Swift for iOS 10? : Let's say I have the user of my app define a phone number in a setup step of my program, saved in the plist as a number with the key "PhoneNum". Now lets say that I want to have a button in the program which, when pressed, generates a text message that says "Hi! How are you today?" to the phone number saved under "PhoneNum". How would I do this? Also, would it be possible to auto-send the text message, or is user confirmation required to send the message?
