DTiPhoneSimulatorErrorDomain Code 2

There are two problems here.1. You have 2 variables called 'scalaRiduz'. They may look the same, but they are completely different. You could have written:var scalaRiduz1111:Double = 0 … func scalaTrafila (…) { var scalaRiduz2222:[Double] = [0, 1, 2] … }Why? Because a 'var' statement always declares a new variable. In your existing code, the 'scalaRiduz' inside the function hides the 'scalaRiduz' outside the function. But they're still different variables.2. This isn't your real code. In your main program, your 'scalaRiduz' isn't even array — it has type Double, not [Double].Here's what I think happened. You had code like this, in a single file:var scalaRiduz:[Double] = [] func scalaTrafila (…) { scalaRiduz:[Double] = [0, 1, 2] // <-- Note that there is NO var } print (scalaRiduz[0]) // prints 0Then you split it into 2 files:var scalaRiduz:[Double] = [0] scalaTrafila () print (scalaRiduz[0])func scalaTrafila () { scalaRiduz:[D

the alert action is displayed briefly then it disappears before the user has time to enter anything into the 2 text fields and before the OK button is pressed.I embedded your code in an @IBAction method, and I couldn't have find a behavior as such.The problem may very probably hide somewhere in the lines you have not shown yet.At least two lines of your code: foundLatitude.text = stringLatitude foundLongitude.text = stringLongitudedo not work as expected. (Or I may be mistaking your expectation for these two lines.)They should be in the action handler of OK.Generally, you should not write any code after calling presentViewController:animated:completion: .

There is no UICollectionViewCall in my code, any suggestion what it can be or how to resolve? You can use the above code to replicate the issue. Error #2, you were right. thanks

Two approaches:1) set up notifications for records being created and when the correct number of notifications come in, do your extra code.2) create a simple counter and increment the counter in the modifyRecordsCompletionBlock (actually, count down to zero) and when the counter hits the correct number execute the extra code.
