[Bug]: iOS object variable not set as soon it hits OneSignal when using Hot Restart

[gabsamples6]

What happened?

1. Launch the app
2. when OneSignal.Debug.LogLevel = LogLevel.VERBOSE; is hit
3. Get System.NullReferenceException: Object reference not set to an instance of an object.
   at OneSignalSDK.DotNet.iOS.iOSDebugManager.set_LogLevel(LogLevel value)

on any OneSignal call I get the above

Steps to reproduce?

1. Launch the app 
2. when     OneSignal.Debug.LogLevel = LogLevel.VERBOSE; is hit
3. Get  System.NullReferenceException: Object reference not set to an instance of an object.
   at OneSignalSDK.DotNet.iOS.iOSDebugManager.set_LogLevel(LogLevel value)

on any OneSignal call I get the above

What did you expect to happen?

Run the app so that I can initialize onesignal and send notification

Any suggestions

Relevant log output

System.NullReferenceException: Object reference not set to an instance of an object.
   at OneSignalSDK.DotNet.iOS.iOSDebugManager.set_LogLevel(LogLevel value)

What .Net version are you using and what version is your Visual Studio?

[gabsamples6]

@shepherd-l using

• visual studio 2022 17.7.4
• <PackageReference Include="OneSignalSDK.DotNet" Version="5.0.0" />
• .net 7
  and also happens with Version Visual Studion 17.8.0 Preview 2.0 .net 8 (which we will be moving as its now got a live licence)

[shepherd-l]

Could you share a sample project with us that reproduces the issue?

[gabsamples6]

@shepherd-l see attached project

See simple attached example - the main point of this sample is that it crashes in iOS when hitting the first line of code where Onesignal is used.

1. Launch app in android

2. Breakpoint on SharedPush.Initialize

3. OneSignal.Debug all good

4. Launch app in iOS

5. Breakpoint on SharedPush.Initialize - OneSignal.Debug

6. Crash -Object variable not set when breakpoint hit

Google-services json and entitlement.plist are empty as not important to demonstrate this bug

thanks again for looking into this.

Any news? have you been able to replicate it?

[Zack-G-I-T]

@shepherd-l we have the same problem. Works fine on Android MAUI, but on ios we cant do anything with onesignal. We tried copying the sample app but cannot get it working. Is there some missing setup or something?

I was unable to reproduce the error with the 5.0.2 release

Could you try upgrading to 5.0.2 and let us know if you are still seeing the issue?

@Zack-G-I-T could you also try upgrading to 5.0.2 as well?
