I am trying to get to the error code in a transaction (Swift 3):
func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
for transaction in transactions {
if let errorCode = (transaction.error as NSError).code {
//Do something
}
}
}
I am getting the below error.
'Error?' is not convertible to 'NSError'; did you mean to use 'as!' to force downcast?`.
Why wont this work? I thought Error could cast to NSError in Swift 3.
Try to cast the Error
object to NSError
then access error code.
if let nsError = error as? NSError {
print(nsError.code)
}
