In Swift, how do you convert a String to Int64?
As of Swift 2.1.1 you can simply initialize Int64 with String
let number: Int64? = Int64("42")
If you don't mind using NSString, you can do this
let str = "\(LLONG_MAX)"let strAsNSString = str as NSStringlet value = strAsNSString.longLongValueNote that unlike toInt(), longLongValue will return 0 if the string is not a legal number whereas toInt() will return nil in that case.
