Universal framework using Xcode 8.3?

Question

I'm trying to build universal swift framework. When I completed developing framework following several tutorials such as

https://medium.com/swiftindia/build-a-custom-universal-framework-on-ios-swift-549c084de7c8

Creating a universal framework using Xcode 8?

Also by using Aggregate target as well but fail to run in Simulator.

Note: I developed using Swift 3, Xcode Version 8.3

I tried with tutorials scripts too but fail.

Also my framework Xcode extension is xcodeproj.

My question is How to develop universal swift framework which will be release to client where he can test through Simulator as well as with real device?

Thanks in advance.

Edit: I followed this answer instruction and successfully build swift framework.

You can also use the following script. Supporting Swift and Simulator as well.

1. just add the content under Project Settings -> Build Phase as new Run Script Phase
2. Build Project
3. Folder will open, showing your zipped framework
