Aim I would like to display the CKError encountered to the user in the app as an alert. So I would like to extract the string from the error that can be displayed to the user. Note: This question is not about UI code to display. Just want to extract a meaningful string from the error. I tried to use localizedDescription but it doesn't seem to contain an appropriate string Code: Given below are the attempts I made: po error <CKError 0x1c464cea0: "Network Unavailable" (3/NSURLErrorDomain:-1009); "The Internet connection appears to be offline."> po error.localizedDescription "The operation couldn

Scenario is taking the app to background and foreground multiple times when its uploading is in progress,didCompleteWithError: method is called while taking app to foreground with error parameter is null. Probabilty is 1/3. How do i find out what went wrong as error parameter does not give anything. The problem is that didCompleteWithError report only client side error, otherwise is nil. iOS doc said: "Server errors are not reported through the error parameter. The only errors your delegate receives through the error parameter are client-side errors , such as being unable to resolve the

Trying to get to the bottom of an issue I've been seeing in production builds and FINALLY was able to reproduce it while testing. Using RestKit v0.23.1, when doing an RKManagedObjectRequestOperation using the following code (while plugged into instruments) I get "An Objective-C message was sent to a deallocated 'NSError' object (zombie)" and the app crashes every time there's objects in the response JSON - if the response is something like "objects = ();" there's no crash - so I'm guessing it's somewhere in the RestKit/Core Data mapping or storage? RKManagedObjectRequestOperation

I get the error "Use of unresolved identifier" when trying to use one of these StoreKit constants: SKErrorClientInvalid SKErrorPaymentCancelled SKErrorPaymentInvalid SKErrorPaymentNotAllowed SKErrorStoreProductNotAvailable SKErrorUnknown Your code may look like this: if transaction.error!.code == SKErrorPaymentCancelled { print("Transaction Cancelled: \(transaction.error!.localizedDescription)") } What changed? Is there a new module I need to import? As of iOS 9.3 certain StoreKit constants have been removed from the SDK. See StoreKit Changes for Swift for the full list of changes. These

var data: NSDictionary = NSJSONSerialization.JSONObjectWithData(responseData, options:NSJSONReadingOptions.AllowFragments, error: error) as NSDictionary; This line of code gives me error NSError is not convertable to NSErrorPointer. So I then thought to change the code to: var data: NSDictionary = NSJSONSerialization.JSONObjectWithData(responseData, options:NSJSONReadingOptions.AllowFragments, error: &error) as NSDictionary; which would turn the NSError error into a NSErrorPointer. But then I get a new error and cannot make sense of it: NSError! is not a subtype of '@|value ST4' These types

I wish to set an NSError pointer from within a block in a project using automatic reference counting. What follows is a simplified version of my code: - (BOOL)frobnicateReturningError:(NSError **)error { NSArray *items = [NSArray arrayWithObjects:@"One", @"Two", @"Three", nil]; __block Frobnicator *blockSelf = self; [items enumerateObjectsUsingBlock:^(id item, NSUInteger idx, BOOL *stop) { [blockSelf doSomethingWithItem:item error:error]; }]; } This compiles but given error may be modified by doSomethingWithItem I tried creating a local NSError for the block to modify, which would then be used
