In App Purchase causes occasional crash

Question

I\'ve searched the internet for help on this but to no avail. My app is live on the app store and a minority of users are reporting the app freezing on them and crashing aft

This is the crash because of the memory issue. I think you putto code like this after some delay it works batter. you can also use GCD Dispatch Timer

public func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {

let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(0.1 * Double(NSEC_PER_SEC)))
                dispatch_after(delayTime, dispatch_get_main_queue()) {

                for transaction in transactions {
  switch (transaction.transactionState) {
  case .Purchased:
    completeTransaction(transaction)
    break
  case .Failed:
    failedTransaction(transaction)
    break
  case .Restored:
    restoreTransaction(transaction)
    break
  case .Deferred:
    break
  case .Purchasing:
    break
  }
 }

} }
