Xcode Missing 64-bit support with standard architectures enabled

Question

I have looked through several similar questions and am still unable to get it to work. When I archive and upload my app to the app store, I get the error message :

iTunes Store operation failed. Missing 64-bit support. Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 8 SDK, included in Xcode 6 or later. To enable 64-bit in your project, we recommend using the default Xcode build setting of "Standard architectures" to build a single binary with both 32-bit and 64-...

As suggested in other questions/answers, I have brought my app up to recommended settings, set Standard Architectures and Valid Architectures to include arm64 (See below)

This did not work, I received the same error message when I tried to upload the app. I don't have any iOS devices connected to my machine while doing this. I also read that some 3rd party libraries may cause this, but I believe the only 3rd party libraries I use are Google Analytics and Google Mobile Ads, both of which I updated recently (I even tried removing Google Analytics but that did not work either). See the linked libraries section:

After doing all of this, I am at a loss as to why the error message still comes up. I also tried deleting the Derived Data. Is there some other setting in one of the classes that could block the app from supporting 64-bit? How do I get this app to support 64-bit?

Questions/answers I tried previously:

iOS app: Missing 64-bit support

iOS: Standard architectures enabled but iTunes not recognising 64 bit support

iOS app submission : missing 64-bit support

Why the Missing 64-bit support happened when upload to the iTunes connect?

Answer 1

To enable 64-bit support:

You need to add "arm64" under "Valid Architectures" and set "Architecture" as "Standard Architecture" as shown in attached screenshot.

Also make sure to turn "Build Active Architectures Only" to NO.

Answer 2

You can manually add 64- bit (arm64) support like this:
