Hi @VaryHice ! Thank you for the report 🙏

It looks like it fails to encode the user-info when writing events in RUM. Do you set any user extra-info that it may have issues encoding in old iOS versions?

Hello @maxep!
Yes I use this code to set client id:

Datadog.addUserExtraInfo(["client_id" : clientId])

where clientId is a string value, i e "730547aaf6853e90872ed546cec6a09ff382f36b68870f63181f994f5dcf54db".

But I've added this only in recent versions, while crash appears in earlier versions where no extra user info is set 🤷‍♂️

Also I noticed other classes in crash logs too, which Crashlytics merged into one issue:

I'm having a similar issue after upgrading to Datadog V2
The issue is inconsistent, I'm not even able to reproduce it on my device, However, a lot of my users are facing this issue.

Hey! sorry for the late reply.. we are still investigating this.

@sathriyanIDPal and @victors1681 could you please confirm that you are also experiencing this crash on iOS 12 only?
@victors1681 do you have by any chance the symbolicated stack trace?

Thank you for your help 🙏

Hi @maxep,
I have checked, and yes, all crashes (Totally 5) occurred only on iOS 12 devices. In our case, it occurred on iOS 12.5.6.

Thanks.

@maxep that's correct! iOS 12.x

Hey @VaryHice, @sathriyanIDPal

We are not able to reproduce the crash on our end. The crash appears in the Swift runtime and there is not much we can do other than a workaround for iOS12, but it will be hard to find without steps to reproduce... We had a similar issue #790 and a fix was applied to Swift, it looks like a similar case here.

Could you share which Xcode version was used to built the faulty app version?

@victors1681 👋
You are experiencing a different crash than the one described in this issue, it seems that your LoggerUtil.init() is not retaining the Logger instance. Could you please open another issue and describe how you initialise Datadog, Logs, and the Logger.create

Hi @maxep
We used Xcode 14.1 if I remember correctly

victors1681 commented Sep 19, 2023

@maxep Sure.. it could be. I had to create an util initialize the logger using a global variable and check if the class is already initialized the reason is after initializing the logger using the Datadog.setUserInfo method I started experiencing the crashing (same implementation before 2.x),

I'm going to revert my changes to report the issue without using the global LoggerProtocol variable.

var loggerInstance: LoggerProtocol?

@objc class LoggerUtil: NSObject {
....

//my constructor
 override init() {
    if Datadog.isInitialized(instanceName: "myapp") && loggerInstance != nil {
            if let instance = loggerInstance {
                self.logger = instance
                return
            }
        }
           
 //
   let logger = Logger.create(with: Logger.Configuration(
            name: "myapp",
            networkInfoEnabled: true,
            remoteLogThreshold: .info,
            consoleLogFormat: .shortWith(prefix: "[iOS App] ")
            ))
 ...
    Datadog.setUserInfo(id: user?.userId ?? "", name: user?.fullName ?? "", email: user?.email ?? "",extraInfo: ["UUID": vendorIdentifier, "device_name": deviceName, "ios_version": iosVersion, "device_model": deviceModel])
....

Hello @maxep,

We have used Xcode 14.3.1

Hey @sathriyanIDPal and @VaryHice 👋

Are you still not able to reproduce on your side? we don't have any clue on what could cause this, other than an issue in Swift runtime. Additionally to Xcode, what dependency manager do you use?
Also, are you seeing any warnings when building your application that could relate to the issue?

Thank you for your help 🙏

@maxep 👋
No didn't face the issue by ourselves, can't test on iOS 12 right now. We use CocoaPods as dependency manager. Didn't notice any warning related to Datadog or crash data.
We also concluded that it's probably iOS runtime bug and so far we decide to just drop iOS 12 support at some moment in near future.

Hello, @maxep.

Are you still not able to reproduce on your side?
Not yet. Will try to replicate this weekend and let you know here.

What dependency manager do you use?
We use CocoaPods as a dependency manager.

Are you seeing any warnings when building your application that could relate to the issue?
Nope, nothing related to this issue.

Thanks.

We are also experiencing this for iOS versions 12.5.x for our Flutter application that runs on iOS.
