CLLocationCoordinate2D can't be instantiated
(2 answers)
Closed 1 year ago.
I'm trying to initialize a CLLocationCoordinate2D from a Swift Playground, and I'm getting the error:
error: Execution was interrupted, reason: signal SIGABRT.
The process has been left at the point where it was interrupted, use "thread return -x" to return to the state before expression evaluation.
Not sure what I'm doing wrong. Here is what I tried:
var temporaryCoordinate = CLLocationCoordinate2D(latitude: 0.0, longitude: 0.0)
You have found a very unusual and interesting bug. I can reproduce your problem by running the following code in a Blank iOS playground:
import UIKit
import CoreLocation
var temporaryCoordinate = CLLocationCoordinate2D(latitude: 0.0, longitude: 0.0)
What is going wrong is that the runtime environment, the Playground, is itself crashing. In the Mac, in the Console app, with Crash Reports left tab, we can see that the Xcode Playground is crashing.

I think the problem is that there are two Core Location binaries in play:
0x18321e000 - 0x1832a8fff com.apple.corelocation (2420.12.16 - 2420.12.16) <F94D1F57-86D5-3A82-8F2B-80A9AEAC0308> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/CoreLocation.framework/CoreLocation
and
0x1b1f96000 - 0x1b1f98fff +libswiftCoreLocation.dylib (5) <EE615605-C11D-3F60-B611-8B1C1D45FEEA> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/swift/libswiftCoreLocation.dylib
and the playground is communicating from one world to the other world; talking to the iOS simulator. But there is an incompatibility between the two as the message is not carried across correctly due to type confusion. This leads to the
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSValue
valueWithMKCoordinate:]: unrecognized selector sent to class
0x1c9d3f588' terminating with uncaught exception of type NSException
I think you should file a bug with Apple. To avoid the problem, write your code based on the iOS Simulator directly, instead of using the Playground. In such circumstances, your code will execute correctly (since it directly will run against the simulator without the intervening bridge from the Playground).
As Alexander says in his comment, there is nothing wrong with the code you posted. The cause of the crash is elsewhere.

I developed a marketplace app using Expo. It works fine on Expo Go both on Android and iOS, as well as a standalone app for Android. The problem is when I build a .tar for iOS simulator or when I upload to Testflight to test it. Then it crashes right after showing the splash screen. I use a managed workflow, and I think I followed all the instructions.
Here's the crash log:

Okay after a weekend of debugging I fixed it. I had my main app component (in Expo) wrapped in a Stripe Provider component. Since I wasn't using Stripe but Paypal for checkout, I deleted the Stripe wrapper and now it works.
if(fontsLoaded){
return (
<StripeProvider
publishableKey="xxxxxxxxxxxxxxxxx"
urlScheme="your-url-scheme" // required for 3D Secure and bank redirects
merchantIdentifier="merchant.com.{{YOUR_APP_NAME}}" // required for Apple Pay
>
<Provider store={store}>
<PersistGate loading={null} persistor={persistor}>
<RootRouter />
</PersistGate>
</Provider>
</StripeProvider>
);
I am unable to edit storyboard files in my xcode project.
I have tried cleaning my Derived Data and cleaning my project but it has had no effect.
In the IBAgent crash log I found this.
I get further errors in the designer "already shutdown" errors. I believe because of the IBAgent crash

This happened when I upgraded to Xcode 13.0.
I couldn't find much help on the subject, but from trial and error, the solution for my situation seemed to be:
open ~/Library/Developer/Xcode/iOS\ DeviceSupport
rm -rf <VERSION>
I did this for every version expect the latest version (in this case 15.0.2 (19A404))
I am unable to reproduce the issue. One of my user sent the crash log and the issue seem to point to NSUserDefault setBool:forKey method.
Not working for user Device iPhone 6, iOS version: 12.4.4. For now only one user contacted due to the App crash.
Working on the devices I tested. (iPad Air 2, iPhone XS, iOS version 13.3)
This is the method I am using.
- (void) saveToDefaults:(NSString*)productId
{
[ [ NSUserDefaults standardUserDefaults ] setBool:YES forKey:productId ];
[ [ NSUserDefaults standardUserDefaults ] synchronize];
}

How can I handle this exception to avoid this problem in the future.
Following up comments discussion and this answer indicating synchronize is not required (as per Apple's iOS 12 release notes):
My target iOS is from 11.2, guess I cannot use it for now.
Yes you can.
Wrapping up my suggestion in comment :
if (#available(iOS 12, *)) {
// don't need to synchronize
} else {
[NSUserDefaults.standardUserDefaults synchronize];
}
The above code #available Swift-like syntax assumes you're using Xcode 9 or higher. Which given the targeted iOS is pretty much a must.
Just to make myself 100% clear I cannot guarantee this will solve this particular crash issue, but it is worth trying as a very low effort fix candidate.
The iOS app I am developing is having this crash with many of my users (I can catch it via PLCrashReporter library). The Exception type is SIGSEGV, so I believe is an error involving memory (like acceding a deallocated variable?).
But how can I discover what triggered it? The first line in the stacktrace involving my app is line 13:
13 ****** 0x004a9b40 _mh_execute_header +
And I really can't catch what this could mean.
Is there a way to see more info, or maybe the first four/five lines can help me more than I think?
Additional information: I use massively CoreData and NSManagedObjects, so I can't check every instance if those.

I've pasted only thread 0 because it seems it is the one which crashed.
This is all new to me and I have no idea how to interpret this log and solve the problem.
I've tested my App on my iPhones 4 and 4s and on a 3GS of a friend of mine and we didn't see any crash.
Now I'm getting 1 star reviews from some people saying iPill is crashing a lot.
Any help will be really appreciated.
Thanks.
I'd say to start in your tables cellForRowAtIndexpath method.
I'd hazard a guess that there's an issue with your data model and it's calling data from an array that is empty.
Just from this crashlog it looks as if you're having an out-of-bounds problem triggered by line 314 of ProssimeDosi.m due to something requesting more data than is available.
See the accepted answer here for a more elaborate explanation: Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSMutableArray objectAtIndex:]: index 1 beyond bounds [0 .. 0]'
