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 after making an In App Purchase (the only IAP in my game, it basically unlocks the full version). Even when they restart their device and try to continue, it crashes again. I haven't been able to reproduce the crash - here is the crash report:

The method referenced as causing the crash is as follows:
public func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
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
}
}
}
I'm not sure where to begin really as the code in paymentQueue: updatedTransactions looks ok to me and was in fact taken direct from a Ray Wenderlich tutorial on IAPs: http://www.raywenderlich.com/105365/in-app-purchases-tutorial-getting-started
This in particular is puzzling me:
function signature specialization <Arg[0] = Dead and Owned To Guaranteed, Arg[1] = Owned To Guaranteed> What does that mean?
Anybody have any ideas? Or advice on how to reproduce the crash? Because it's only happened a handful of times, could it be something to do with the user's device or Apple's IAP handling, or is it definitely my code?
Thanks in advance!
Edit:
In response to Alpesh's answer, my function now looks like this:
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:
self.completeTransaction(transaction)
break
case .Failed:
self.failedTransaction(transaction)
break
case .Restored:
self.restoreTransaction(transaction)
break
case .Deferred:
break
case .Purchasing:
break
}
}
}
}
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
}
}
} }
