swift - How do I get a UITextField input as an Integer -
i uitextfield input integer? tried int(uitextfield input) , throws error. tried making variable same value, did not work. if define -> @iboutlet weak var textfield: uitextfield! can use (textfield.text! nsstring).intvalue or int(textfield.text!) . must use exclamation mark. but define -> let textfield = uitextfield() textfield.text = "007" you don't need use exclamation mark edit: (textfield.text! nsstring).intvalue int32 format, can normal int format -> int((textfield.text! nsstring).intvalue)
