I've got an error in my app (iOS 8 to iOS 11) :

I've read some subjects about errors like this one. Each time, people says that comes from Permissions in infos.plist.
App uses camera, library, geolocation. So I add :
Privacy - Camera Usage Description
Privacy - Location When in Use
Privacy - Photo Library Usage Description
But there is always the same problem.
I add Microphone usage in plist, but same crash occurs.
I don't understand the crash. On my iPhone, everything works perfectly but on some devices, this error cause crashes. Could you help me please ?
Thanks.
Check all of your WKWebView that is are loading images.
If you long press on Webview it shows an option to save photos in app.
Fix for the crash:
webView?.allowsLinkPreview = false

After releasing my ios application, I started to get lots of crash such as CFNetwork, CoreMotion etc. And then I thought, I did something wrong on my project. I sent a new build after reversed everything what I did. But problem is I am getting same crashes. There is no difference between previous build which I do not get these errors and current build. How is it possible that? Is there anyone who has an idea? I am attaching the most crash logs that I get. Interesting thing is I am NOT getting this crash on ios latest version (15.4.1). I am getting this crash only below ios 15.4.1. I am not able to reproduce on my side. I am sharing firebase logs.

XPC API Misuse by a NSURLSession
Details:
The stack trace indicates an issue with usage of the XPC API. It looks like NSURLSession background uploads is causing issues with XPC. Since XPC is not available to third-party developers on iOS, this is probably an Apple bug. If this affects your ability to use background uploads, we recommend filing a radar with Apple and working around background uploads, if possible.

The crashes only appears on iOS9, none whatsoever on iOS8, but this could just be a coincidence. I am also seeing this via Crittercism breadcrumbs:
I am also using Background Fetches which do hit the network layer.
Any idea why this is happing?
This looks to me like a bug with Crittercism. The class CRNSURLSessionTaskProxy is a Crittercism class (see below), so it's crashing in their code, which is corroborated by the errors in the Crittercism breadcrumbs.
The only Google hit (other than this question) for the class name is this one. If you look at the other classes in that dump that start with CR, you will see CRBreadcrumbs and CRCrash.
Also here's a dump of the Crittercism framework in the Hopper disassembler:
Pretty conclusive I would say.
This is the crash report I received from crashlytics and I don't have the slightest clue on what it means or what to do about this. Any tips or suggestions will be appreciated.

Do you have any part of your app where the user clicks on a URL or specifies a URL which is then handled by your app, or by the system on behalf of your app. The subsystem that does this is DataDetectorsCore.
If you have code around that area, it would be a good idea to add log messages, assert checks, validation, and unit test code.
It might be that you are receiving maliciously crafted URLs; here is an example but for the Mac platform: http://nakedsecurity.sophos.com/2013/02/06/anatomy-of-a-bug-how-mac-os-x-chokes-if-you-type-file/
I am getting a weird timeout crash via iTunes during app launch. Here is the stack trace. Seems like something to do with the location service (yes, I do ask for a user's location). Does anyone have any experience with such a crash?

I had a similar issue. I resolved it by rebooting my iOS device entirely.
I believe the issue is that the remote debug server is in an unexpected state and causing the app to break the running application (libxpc is involved in remote debugging I believe). As a result the best way to clean this up is to simply reboot.
