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 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'm getting crash from our custom keyboard extension that shows doesNotRecognizeSelector in the report but the code that's crashing isn't mine... it's in Foundation/CoreFoundation. Here's the crash report...

I can see the doesNotRecognizeSelector at line 2 and the nearest thing in the stack is NSExtensionContext _willPerformHostCallback. I looked through all the threads in the report and nothing shows anything from our code. I searched our codebase and I don't see any code where we override willPerformHostCallback or anything derived from NSExtensionContext for that matter.
Can anybody see what the deal is here?
TIA, Mike
I have an App which has a custom framework. When my app crashes, I could symbolicate the crash log in which I can only symbolicate the symbols in my app. But I want to symbolicate the framework as well. And I cannot create or find where the dsym file for the custom framework.
