When I try to fetch user data from Firebase a crash occurs for some users, I can't reproduce this crash myself but I do have the following crash log:

If I understand the crash log correctly the code which is causing the crash is within the fetchUserHistoryFromDatabase function:
func fetchUserHistoryFromDatabase(uid : String, completionHandler: #escaping([String : Any]?) -> Void ) {
ref?.child("users").child(uid).child("runData").observeSingleEvent(of: .value, with: { snapshot in
guard let result = snapshot.value as? [String:Any] else {
print("Error no rundata")
completionHandler(nil)
return
}
completionHandler(result)
})
}
This function is called from downloadHistory where potential nil values are handled:
private func downloadHistory(completionHandler: #escaping () -> Void) {
if let id = Auth.auth().currentUser?.uid {
FetchFromDatabase().fetchUserHistoryFromDatabase(uid : id, completionHandler: { [weak self] dict in
if dict != nil {
for run in dict! {
self?.determineTimeStamp(run : run)
}
if !(self!.tempDict.isEmpty) {
let sortedDict = self?.tempDict.keys.sorted(by: { $0 > $1 } )
self?.convertDictToArray(sortedDict: sortedDict!)
}
}
completionHandler()
}
)}
}
Any help here is greatly appreciated.
Remove the force unwrapping from your code. Every ! is an invitation for a crash.
private func downloadHistory(completionHandler: #escaping () -> Void) {
if let id = Auth.auth().currentUser?.uid {
FetchFromDatabase().fetchUserHistoryFromDatabase(uid : id, completionHandler: { [weak self] dict in
guard let self = self else {
completion()
return
}
if let dict = dict {
for run in dict {
self.determineTimeStamp(run : run)
}
if !self.tempDict.isEmpty {
let sortedDict = self.tempDict.keys.sorted(by: { $0 > $1 } )
self.convertDictToArray(sortedDict: sortedDict)
}
}
completionHandler()
}
)}
}
I notice a self! there dangerous, because a user could leave the calling context of the function and since the closure has a capture list of weak self, it should return nil but you are forcing it
try this
private func downloadHistory(completionHandler: #escaping () -> Void) {
if let id = Auth.auth().currentUser?.uid {
FetchFromDatabase().fetchUserHistoryFromDatabase(uid : id, completionHandler: { [weak self] dict in
guard let self = self else { completionHandler()
return }
if let safeDict = dict {
for run in dict {
self.determineTimeStamp(run : run)
}
if (self.tempDict.isEmpty) {
let sortedDict = self.tempDict.keys.sorted(by: { $0 > $1 } )
self.convertDictToArray(sortedDict: sortedDict)
}
}
completionHandler()
}
)}
}

Here is the my other function. i am sending data to my Socket function. i did't got the crash but its reported into firebase. Also in firebase has not much more information about the crash. its just show the function name only.
private func sendRequest() {
self.calculateMessageData()

var txData = [UInt8()]
var crc: Int
if self.msgID == Int8(EnMessageType.basicSafetyMessage.rawValue) {

} else {
requestData = self.getPersonalSafetyMessage()
}
crc = computeCRC(data: requestData!, length: requestData!.count)
// wrap data in 7E, do byte stuffing and add CRC
txData = []
txData.append(0x7E)
for ii in 0..<requestData!.count {

case 0x7D:
txData.append(0x7D)
txData.append(0x5D)
break
case 0x7E:
txData.append(0x7D)
txData.append(0x5E)
break
default:
txData.append(requestData![ii])
break
}
}
txData.append((UInt8)(crc >> 8))
txData.append((UInt8)(crc & 0xFF))
txData.append(0x7E)
requestData = (Data)(txData)
if AppSingletonVariable.sharedInstance.isConnected == true { AppSingletonVariable.sharedInstance.mySocket.sendDataToServer(reqData: requestData!)
}
}
Thanks,
You can see from the crash description that there is issue in 2nd closure in sendDataRecursively() function:
DispatchQueue.main.async {
self.previousStatusWhenDisconnect = self.motionDetectionLbl?.text ?? ""
self.appDelegate.statusLbl?.text = String(format: "%# %#", (self.appDelegate.statusLbl?.text)!, StartVCStringsEnglish.disConnectedString)
}
self.networkTimer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(self.checkNetworkRecursively), userInfo: nil, repeats: true)
The issue is probably '!' in this expression:
(self.appDelegate.statusLbl?.text)!
If statusLbl is nil, this code crashes. As it was mentioned in comment, it's not safe to force unwrap optionals and this is the reason.
Replace your closure with this:
DispatchQueue.main.async {
self.previousStatusWhenDisconnect = self.motionDetectionLbl?.text ?? ""
if let text = self.appDelegate.statusLbl?.text {
self.appDelegate.statusLbl?.text = String(format: "%# %#", text, StartVCStringsEnglish.disConnectedString)
}
}
self.networkTimer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(self.checkNetworkRecursively), userInfo: nil, repeats: true)
When delegate is call, is crash with: EXC_BAD_ACCESS KERN_INVALID_ADDRESS

I have a TableView and a Search Controller. They both work perfectly with regards to displaying the info, searching, etc. The problem arises when you go to select one of the cells.
In my code, there are 4 ways you can select the cell... If a bool isAboutNewPost == true / false, and if the search is active or not. If the search controller is active, I am using the data from a filtered array.
When you select a cell and the search controller is not active, it works perfectly. When you select a cell and the search controller is active, but the bool is false, it works perfectly. When you select a cell and the search controller is active and the bool is true, it crashes. I have no clue why, because it is almost identical code.

I found the solution. It had to do with how the view was loaded in the first place. Commented out code was the original code. Fixed it by making it a modal segue.
#IBAction func goToUnlockPost(sender: AnyObject) {
// let vc = self.storyboard!.instantiateViewControllerWithIdentifier("NewAddPost") as! NewAddPostViewController
// vc.isAboutNewPost = true
// vc.comingFromUnlockPost = true
// self.presentViewController(vc, animated: true, completion: nil)
self.performSegueWithIdentifier("tappedUnlockPost", sender: nil)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

let destinationNavigationController = segue.destinationViewController as! UINavigationController
let targetController = destinationNavigationController.topViewController as! NewAddPostViewController
//targetController = segue.destinationViewController as! NewAddPostViewController
targetController.isAboutNewPost = true
targetController.comingFromUnlockPost = true
}
}

And propagating to code, user tapps the tabbar button ( i'm using custom tabbar ) :
#IBAction func cameraControllerSelected()
{
setUpTabBar(forSelectedActionSignContainer: cameraSign)
}
And the following code executes :
private func setUpTabBar ( forSelectedActionSignContainer imageView : UIImageView ) -> Void
{
var viewControllerIndex = 0
if ( imageView == feedSign )
{
feedSign.hidden = false
exploreSign.hidden = true
cameraSign.hidden = true
chatSign.hidden = true
profileSign.hidden = true
viewControllerIndex = 0
}
if ( imageView == exploreSign )
{
feedSign.hidden = true
exploreSign.hidden = false
cameraSign.hidden = true
chatSign.hidden = true
profileSign.hidden = true
viewControllerIndex = 1
}
if ( imageView == cameraSign )
{
feedSign.hidden = true
exploreSign.hidden = true
cameraSign.hidden = false
chatSign.hidden = true
profileSign.hidden = true
viewControllerIndex = 2
}
if ( imageView == chatSign )
{
feedSign.hidden = true
exploreSign.hidden = true
cameraSign.hidden = true
chatSign.hidden = false
profileSign.hidden = true
viewControllerIndex = 3
}
if ( imageView == profileSign )
{
feedSign.hidden = true
exploreSign.hidden = true
cameraSign.hidden = true
chatSign.hidden = true
profileSign.hidden = false
viewControllerIndex = 4
}
if ( !shouldDismissTopOrReload(viewControllerAtIndex: viewControllerIndex))
{
displayViewController(atIndex: viewControllerIndex)
signOnScreen = imageView
}
}
And it appears only on release builds, on debug everything fine. Is an optimising compiler issue? Cause i have the same procedure setUpTabbar() with no arguments. Other functions - such as shouldDismissTopOrReload(viewControllerAtIndex: viewControllerIndex) and displayViewController(atIndex: viewControllerIndex) are reliable, and well-covered by tests. Any ideas? I've got almost 200 crashes!!
