ISSUE: Firebase Cloud Storage Unity SDK gives iOS Build Error

[Sai Praneeth Gunuputi]

Hello,

We have many SDKs in our Unity project. Firebase is giving iOS Build error.

At first, we thought it could be due to SDK conflict.

BUT, we checked in an empty Unity Project.

It is still giving Build error.

We are using

Unity 2018.2.20

firebase_unity_sdk_6.7.0

Here is the empty unity project with ONLY Firebase SDK.

https://drive.google.com/file/d/1l2en8o9IpYXcd2qH2HajjAuTszTZCGg5/view?usp=sharing

Please help us resolve this error ASAP. 

It is preventing us from using Firebase.

Here is the Error Log:

Hi Sai,

Could you check your iOS Resolver Settings at Assets > Play Services Resolver > iOS Resolver > Settings ?

Make sure that Podfile Generation is checked and Cocoapods Integration is set to Xcode Workspace - Add Cocoapods to Xcode workspace

I suspect that you did not install Cocoapods on your machine.  As a result, iOS resolver cannot add podfile to the Xcode workspace.

If that is the case, please install Cocoapods or use the options under 

  Assets > Play Services Resolver > iOS Resolver > Install Cocoapods

Please let us know if this works for you.
