I have this code:
if (self.leadObject != nil) {
[result addObject:self.leadObject];
}
And sometimes app close with this error:
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[__NSArrayM
insertObject:atIndex:]: object cannot be nil'
The execution pass if command and try to add the object self.leadObject inside of result array although this object is nil.
Can someone explain this??
Update:

I suspect that you have not allocated your result object. Do so if you didn't and then Log the self.leadObject to make sure that it isn't an NSNull
if (self.leadObject) {
NSLog(#"%#", self.leadObject);
[result addObject:self.leadObject];
}

NSKeyedUnarchiver.UnarchivedArrayOfObjects() terminates app with 'NSInvalidArgumentException', reason: '-[__NSCFData count]
track conforms to NSManagedObject
However decodedTrackLocation is declared #Published public var decodedTrackLocation: [CLLocation] = [], as it is not persistent, but supposed to be in memory.
The below code works on certain 'saves', but sometimes it throws an exception and I can't figure out what to do about it.
It crashes at 'if let final =' and throws this exception:

The reason the NSKeyedUnarchiver fails is because I did something stupid, I stored the wrong Data. What I can't grasp is why the do-try-catch block this code lives in, doesn't work/catch.
Any help would be appreciated.
The code in Question:
do{
let out = try Data(referencing: NSData(data: track.trackLocation).decompressed(using: .lzma))
let archiver = try NSKeyedUnarchiver(forReadingFrom: out)
archiver.requiresSecureCoding = true
archiver.decodingFailurePolicy = .setErrorAndReturn
if let final = archiver.decodeArrayOfObjects(ofClass: CLLocation.self, forKey: NSKeyedArchiveRootObjectKey){
track.decodedTrackLocation = final
}
} catch {
print(error)
}
do{
let out = try Data(referencing: NSData(data: track.trackLocation).decompressed(using: .lzma))
if let final = try NSKeyedUnarchiver.unarchivedArrayOfObjects(ofClass: CLLocation.self, from: out){
track.decodedTrackLocation = final
}
} catch {
print(error)
}
Because it's not an Error that is thrown (throws), it's a NSInvalidArgumentException, a NSException, on Objective-C one. You can look for it :) - Larme
I learned something new!
I have to experience this issue upon trying to build a release in a simulator.
**** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'data parameter is nil'
terminating with uncaught exception of type NSException

When I am trying to access array, ends up with this exception but when I add breakpoint on and try to print in the debugger log, array seems to have values and does not appeared to be wrong
oldDevices.forEach { (oldDevice) in
if(self.averageRssis.count > 0){
if(self.averageRssis[oldDevice.bluetoothId] != nil)
{
self.averageRssis[oldDevice.bluetoothId] = nil
DispatchQueue.main.async {
self.bluetoothManager.remove(device:
oldDevice)
}
}
}

In my code I have to get the value from NSDictionary but it crashes and the crash issue is,
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<__NSCFString 0x155000fa0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key success.'
Here I show the the code what I am trying.
NSLog(#"finalValNotify is: %#", finalValNotify);
if (finalValNotify) {
int successResult=[[finalValNotify valueForKey:#"success"]intValue]; ====>This line app crashed
if (successResult==1) {
NSLog(#"finalValNotify is: %d", successResult);
}
}
Here I show the printed NSDictionary value:
finalValNotify is: {"multicast_id":5704734283387573862,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1534486056437155%1dbdaa031dbdaa03"}]}
But I don't know the reason for why the crash was occur.
If finalValNotify is your NSDictionary then use as -
int successResult = [finalValNotify[#"success"] intValue];

The line of code it is referring to is as below:
self.ref.child("users").observeSingleEventOfType(.Value, withBlock: { (snapshot) in
for user in snapshot.children{
var numVids = NSDictionary()
if ((user.hasChild("videos")) == true){
--> numVids = user.value["videos"] as! NSDictionary
}
}
As soon as I remove the import Algolia module the error is removed, I have tried changing the version of the module and even switching to use the objc version but the error was the same.
Anyone seen something like this before?
