I keep getting this crash on IOS 6 but I am not sure what is wrong. Does anyone know what it means?

The application is using the MKMapkit in IOS 6.
This is an internal bug. Report this to Apple.
You may be able to use the Simulator's "Reset Content" thing (in the app/iOS Simulator menu) to clear out caches if this is happening in the Simulator.
Looks like the issue is caused by accessing a released object from within or soon after VectorKit's stopAnimation: method is called. I'm not familiar with VectorKit, so you might look in that method or what looks to be the onTimerFired: delegate callback.
Good luck.

I'm getting a unconditionallyBridgeFromObjectiveC crash in an Apple Watch app out in the wild. I'm not able to replicate it locally, and haven't ever encountered it on a test device through regular use. Here's the info about the exception:
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000001, 0x00000000224c58b0
Termination Signal: Trace/BPT trap: 5
Termination Reason: Namespace SIGNAL, Code 0x5
Terminating Process: exc handler [653]
The crash reports show it's happening on the second line of this code:
let name: String
name = WKInterfaceDevice.current().name
(I have these on separate lines for better readability in my code)
I'm not very family with Objective-C or how things can fail related to Objective-C values, but from what I've found around the Internet, here's my guess:
Even though the API says that WKInterfaceDevice.current().name is a String instead of String?, name is somehow actually a nil value in some cases.
As a possible solution, I'm thinking that instead of name: String I should use name: String? and then make sure it's non-nil later. Does this make sense? Would that help with the issue, or would it be possible that it still crashes from trying to store WKInterfaceDevice.current().name in a constant of type String?? Is there some other kind of safety check I should be doing on WKInterfaceDevice.current().name first?
This crash is not happening much (on at least 7 devices out of ~5000 in about 5 days) but it's the most frequent crash in the newest version of my app, so I'm trying to use it as a learning opportunity to make my app more robust. I guess maybe it could be an issue in WatchKit rather than a problem with my code? Or something that could only be checked and solved with Objective-C?

WatchConnectivityManager class:
class WatchConnectivityManager {
static let shared = WatchConnectivityManager()
let session = WCSession.default
func sendWatchInfo() {
if session.activationState == .activated {
let name = getCurrentWatchInfo()
let message: [String : Any] = ["appleWatchName" : name]
if session.isReachable {
session.sendMessage(message,
replyHandler: nil,
errorHandler: nil)
}
do {
try session.updateApplicationContext(message)
} catch(let error) {
fatalError(error.localizedDescription)
}
}
}
private func getCurrentWatchInfo() -> String {
let name: String
name = WKInterfaceDevice.current().name
return name
}
}
Even though the API says that WKInterfaceDevice.current().name is a String instead of String?, name is somehow actually a nil value in some cases.
It can't be nil. name is a property declared as:
var name: String { get }
It can be an empty string, but not nil (Swift context). And the Objective-C:
#property(nonatomic, readonly, copy) NSString *name;
It's encapsulated with the NS_ASSUME_NONNULL_BEGIN & NS_ASSUME_NONNULL_END which effectively means:
#property(nonatomic, readonly, copy) NSString * _Nonnull safeName;
Read Nullability and Objective-C to see how it affects Objective-C -> Swift.
Actually it can be nil in the Objective-C context, but it violates the _Nonnull contract then.
As a possible solution, I'm thinking that instead of name: String I should use name: String?.
I don't think it's going to help even if you can do this. Imagine you have the following method1:
- (NSString * _Nonnull)canNotBeNilNothing {
return nil;
}
Used in Swift:
let name: String? = WKInterfaceDevice.current().canNotBeNilNothing();
print("\(String(describing: name))")
You still get the Optional(""), not nil. And it's expected, because there's this _Nonnull (it violates the contract, but it's another story).
You can create something like this if you are really sure it can return nil in Objective-C:
- (NSString * _Nullable)maybeName {
return [self name];
}
And then you can use String? in Swift and it can become nil if [self name] will return nil.
Possible causes of your problem
Bug somewhere in the WatchKit (Incorrect nullability annotation, ...)
Something else
I'm not sure what's happening, because I didn't see the stacktrace.
Possible solution
WatchKit & Objective-C problem (throws an exception)? It might be fixable with the following wrapper in Objective-C:
- (NSString * _Nullable)maybeName {
#try {
return [self name];
}
#catch (NSException *exception) {
// Return nil or handle it your way
return nil;
}
}
Bridging issue (incorrect nullability)? It might be fixable with the following code in Swift:
extension WKInterfaceDevice {
var maybeName: String? {
self.perform(#selector(getter: WKInterfaceDevice.name))?.takeRetainedValue() as! String?
}
}
1 In general, you should look at nullable and nonnull roughly the way you currently use assertions or exceptions: violating the contract is a programmer error. In particular, return values are something you control, so you should never return nil for a non-nullable return type unless it is for backwards-compatibility. (Nullability and Objective-C)
This crash is from crash report of app. Multiple URL requests crash cause of it. I want to figure out how to repeat the crash and why the crash happened.

I have a strage crash scenario to crash the app!
When you do a fresh install by running the app from Xcode; the application will run perfectly.
But I installed by current app from app store, then run the application, now everything is perfect till you click on home button, the application will crash at that moment! What's the problem? And How could I solve it?

Since there is not source code to look at my guess would be you have registered for
an observer for NSNotificationCenter and you have not removed the observer before the
application terminates.
This will cause you problems if an NSNotification was delivered to a deallocated
listener.
It appears one of UIApplicationDidEnterBackgroundNotification listeners is deallocated without unregistering from observing UIApplicationDidEnterBackgroundNotification notification
Today i tried running my app on my iPhone device, and it crashed! It worked perfectly fine on the simulator, I don't know what the problem is.

I have tried to look for the error, but I do not know what to look for. Can someone help solve this problem?
CCSprite initWithTexture: raises the exception that causes your app to exit. I'm not entirely up on Cocos2d but a quick check in the documentation suggests it raises exceptions on failure to find named files.
That being the case, I'd guess the problem is simply one of filename case. Macs are by default case insensitive. So if you have FunnyImage.png then the simulator will succeed if you attempt to load funnyimage.png.
iOS devices are case sensitive. So it will fail if you attempt to load funnyimage.png.
So probably what you want to do is check that all the filenames you've used in code exactly match the case of the actual files.
Here's the issue. I have the .xarchive with all the DSYMs but for whatever reason using symbolicatecrash or xcode is only converting some of the symbols to lines while leaving other ones unconverted. Any ideas? I'm using xCode 4.3.2 on OS X Lion.
For example, from a crash log from the appstore
