Did anyone upgrade successfully? 

Thanks,

Do you have the iOS plugin installed?

Could you enable verbose logging under "Assets > Play Services Resolver > iOS Resolver > Settings" then share the logs?

The code that loads the Xcode extension is here https://github.com/googlesamples/unity-jar-resolver/blob/master/source/IOSResolver/src/IOSResolver.cs#L265 if you're interested in taking a look at what could be going wrong.

Cheers,

Stewart

Attach the log after enabling verbose logging for Android and iOS. For iOS I cannot open the setting screen, nothing happened.

[Stewart Miles]

Thanks for the logs Anh.  The logs look like you're trying to build a project on Unity Cloud Build, is this also a problem with local builds?  Is there anything peculiar about your build environment (e.g machine configuration) that we should be aware of?

I just tried this out with a vanilla install with:

• OSX: 10.12.3
• System language: en-US
• Unity 5.6.01f3
• Firebase SDK 3.0.1

I used the Unity installer which installed under /Applications/Unity .

I'll check out Unity Cloud Build next.

Cheers,

Stewart

Oh you're trying to build for iOS on Windows ?  That's a use case that we don't support I'm afraid.

Hi,

Sorry I cannot get it. The users are able to build the XCode project in Windows machine and it's the default and normal process of Unity.

These errors appear in the Editor even before I build the project. 

Anyways, I will try on my Mac and let you know the result.

Thanks,

Anh

[Stewart Miles]

See https://docs.unity3d.com/Manual/iphone-BuildProcess.html you can generate the Xcode project on a Windows machine and that's about it, the project still needs to be built on an OSX machine.  https://forum.unity3d.com/threads/build-on-windows-deploy-to-ios-new-to-unity.364368/ has some discussion about this as well.

In our case the limitation is due to our use of Cocoapods, we pull in iOS dependencies via Cocoapods then inject those into the Xcode project generated by Unity.  So even if our IOSResolver plugin (source here BTW https://github.com/googlesamples/unity-jar-resolver/tree/master/source/IOSResolver) didn't fail to find the iOS extension DLL provided by Unity - we use this to modify the Xcode project - the build would still fail as Cocoapod installation won't run on Windows as their tools don't work on Windows.  I guess we could partially support this use case by fixing the IOS resolver to find the iOS extension on Windows to generate a Podfile without running Cocoapod install but you would still need to copy the final project to an OSX machine, run "pod install" to download the dependencies required and finally build it using Xcode.

Is there anything you can share about your particular use case and the number of users affected by this?

Cheers,

Stewart

I have the same errors too!

As Anh said, it's not happens when build, but every time I put Unity back to foreground, the errors appears. It seems Unity trying to reload/verify the assets and fires Firebase.Editor.XcodeProjectPatcher?

I am on:
Unity 5.5.3p2 - Android Build
macOS 10.12.5

iOS Resolver Settings:
Podfile Generation: On
Cocoapods Integration: Xcode Workspace
Auto Install...: On

Log:

TypeLoadException: Could not load type 'UnityEditor.iOS.Xcode.PlistDocument' from assembly 'Unity.iOS.Extensions.Xcode, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

Do you by any chance have the Firebase settings window open when this happens?

Is it possible you have the iOS platform selected but not active for build?

We've been playing around with this and haven't reproduced the problem.  A screengrab of the behavior would be great.

Stewart

Also it would be great to try this out with the 4.0.0 release we posted today.
