I'm working on an application with virtual camera plugin for macOS by using swiftUI & swift. It has also C++ & objective C library. When we use that plugin via zoom crash is happening randomly.
What's the main reason of this crash. I made several changes on my code but didn't get rid of this crash. Is there anybody who can explain?
Crash report is provided below.

Invalid address at 0x20 almost always means a NULL pointer to an object or struct was dereferenced and a member at offset 32 bytes was accessed.
The crash is in Stream.sendInformation(information:with:) in a call to [object retain]. Typically it is safe to retain a nil ptr in objc, so I’d probably be looking carefully at whether swift is making any guarantees about nullability here that might be circumventing that. I don’t use swift much, and can’t say I’m sure whether the objc nil safety arises out of objc_retain or more likely objc_msg_send first. Anyway, running the thing in the debugger will probably shed some light on what is going on. You might also address any warnings in your build about places where you ignored nullability requirements, or perhaps you set something nullable in your own interface and failed to live up to the requirement.
My app is crashing a lot lately and it's throwing this as an error:
NSOperationQueue 0x2806fd260 (QOS: UNSPECIFIED) EXC_BAD_ACCESS
KERN_INVALID_ADDRESS 0x0000000000000000.
I can't find the call that causes this problem. Can someone help me solve this problem please?

There are also several times, the built goes succesfully... is anyone sperimentig this issue ?
I am receiving this backtrace from TestFlight regarding one interesting crash.
As far as I understood, the application crashes at some point, when using CoreTelephony. Can this be possible of someone "calling" while the user is using the application?
To my knowledge, the application is not using the CoreTelephony Framework. The Exception reason is SIGSEGV and the crash thread is 0
Thank You!

EDIT: There is a fix for this bug in sdk 1.3.0-beta.2 available here: https://testflightapp.com/sdk/download/
I work at TestFlight. We have just recently discovered this bug. It is an iOS bug with CoreTelephony. The TestFlight SDK uses CoreTelephony. So this will sometimes cause crashes. We have a fix that is going to be ready very soon. It will be included in the next beta (probably 1.3.0-beta.2). I'm very sorry for the trouble!
Jason
More information on the crash for those interested:
There is an iOS bug that causes instances of the CTTelephonyNetworkInfo class to sometimes get notifications after they have been deallocated. Instead of instantiating, using, and releasing instances you must instead retain and never release them to work around the bug.
My XCode crashes and crashes and crashes and i can't open my project here is the error that i receive

I tried removing xcuserdata folder from .xcodeproj file that didn't worked
I tried removing the project from repository in XCode -> Organizer
I tried removing the derived project data that
I really don't know what the problem is, we are using a SVN server on the network so we can sync the sources of the projects.
There is a good chance that is fixed in Xcode 4.5.1:
Source Control
Issues interacting with working copies known by the Xcode app. 12364258, 12389205, 12389198
The release notes are available on the Apple Developer Download site (here); they don't appear to be updated on the main Apple Developer website.
Details: Attempted to add repository (IDESourceControlRepository) Name:192.168.1, Type:Subversion, Location:svn://192.168.1.20 when (IDESourceControlRepository) Name:192.168.1, Type:Subversion, Location:svn://192.168.1.20 already existed.
I would remove all your repositories from Xcode and add them again.
I am running Xcode 4.5.1 and just started having this problem today. The app was running in the simulator and then the simulator started acting funny so I decided to stop everything and close Xcode. I had to blast it. When I tried to relaunch I got this error and cannot launch anymore. Clearly something got messed up.
