I've been using:
func isValidPassword(testStr2:String) -> Bool {
println("validate password: \(testStr2)")
let passwordRegEx = "[A-Z0-9a-z._%+-:/><#]{6,30}"
if let passwordTest = NSPredicate(format: "SELF MATCHES %@", passwordRegEx) {
return passwordTest.evaluateWithObject(testStr2)
}
return false
}
to check that string has the appropriate characters. But since the swift 1.2 Update, I get an error saying "Bound value in a conditional binding must be of an Optional type"
I've tried adding question marks. But I can't find how to fix the problem. Anyone know what's gone wrong?
extension NSPredicate {
convenience init(format predicateFormat: String, _ args: CVarArgType...)
}
is not a failable initializer anymore in Swift 1.2, so you cannot (and need not) test the return value with optional binding:
let passwordTest = NSPredicate(format: "SELF MATCHES %@", passwordRegEx)
return passwordTest.evaluateWithObject(testStr2)
