Got "ArgumentNullException: Argument cannot be null." When build on iOS

It's okay when I build with "Replace" but not okay when I build with "Append"

I try to figure out solutions, but it's all about UnityEditor.iOS.Xcode namespace;

I'm using Unity 5.0.0f4 Personal.

And Plugins are
- IOS Native
- Facebook SDK
- Unibill
- Smartlocalization
- Anti-Cheat Toolkit
- UnityRandom
- GoogleMobileAds
- GoogleAnalytics

Stacktrace is below.

We're getting the same error and similar stacktrace. I've just created a new blank project and testing each asset at a time. I'll make an update if we find anything out.

Thanks for mentioning about the 'Replace' instead of 'Append' breadceo. We were doing Replace but still having that problem, however we decided to delete the build folder and start with a fresh empty folder.

So far so good, Unity 5 built to an iPhone 5 with mono backend fine and also IL2CPP on an iPad Air 2.

 

Thanks for your replay O4s. It's good for you to solve this problem.

I tried your solution, however I faced a new kind of error.
Unibill uses POST method to fetch inventory data but IL2CPP doesn't support WWW POST yet.
I decide to downgrade my project and wait for their updates.

 

Version 5.0.0p1. I deleted old build before building. Getting this error:

Any update on this bug? I'm getting it too

 

Thanks for reply. I'll test and post result!

 

Exactly the same on 5.3 latest when you

void OnApplicationPause(bool paused)

 

I am currently getting it with this line:
List<string> lst = stringToEdit.OfType<string> ().ToList ();

This is used within an editor window. When I open the window, it gives this error. As soon as I open the script, press space (for whitespace) and save, it works fine... anyone know if this IS a bug? or could this be something I am doing wrong?

Edit: I am using Version 5.3.1p2

 

It was infact, something I was doing wrong.

I didn't initialize my string correctly.
Old:
public string[] stringToEdit;

New:
public string[] stringToEdit = new string[2];

 

ArgumentNullException: Argument cannot be null.

in 2017.1.1p2

ArgumentNullException: Argument cannot be null.

Any update on this Unity bug?

 

Unity 2019.3, got this bug with FB lib. I've found a workaround. When you got this error. Start your Xcode project directly form XCode, it will build with error, but you should only set correct signing certificates in Signing & Capabilities tab.
After that return to Unity and build ios, but this time with APPEND (not Replace).
