Hello.
A crash occurs in the deployed app, but it has not been resolved for several months, so we ask if you can help.
The crash log appears to cause SIGTRAP when calling addMissionCards(...).
private func addMissionCards(toParsedItems items: inout [AnyObject], missionCards: [JHFeedMissionCard], existingItemsCount: Int) {
I saw the Apple development documentation as SIGTRAP happens when the force unwrapp object is nil.
Swift code will terminate with this exception type if an unexpected condition is encountered at runtime such as:
a non-optional type with a nil value
a failed forced type conversion
So, even though items and missionCards that are passed as arguments to the addMissionCard(...) function are optional binding, there is still a problem.
Over the past few months, I've been adding defense codes to potentially problematic areas, but I haven't earned any income.

Hi
I am working on my app to support ipad split view.
My problem is that the location permission request popup doesn't appear immediately when split view is activated.
The summarized code is below.
import CoreLocation
class MyViewController: UIViewController {
var locationManager = CLLocationManager()
//skip code...
@objc func touchUpInsideLocationButton(_ sender: Any) {
self.locationManager.requestWhenInUseAuthorization()
}
}
After the code that handles the button touch is executed, the system popup requesting the location permission does not appear.
When I close the iPad split view (Drag the app divider to the left or right edge of the screen), a system popup appears at that time.
When requesting permission to access photos in iPad split view, a system pop-up appeared immediately.
The location information permission popup should also appear immediately, but I'm not sure if it's a bug or the intended behavior.
Please help.
Have a nice day 😄
