How to prevent debugging on custom iOS framework

Question

I developed my own iOS framework(for my clients) which provides login and some other features. I imported my framework into a test project and all runs well. In test project I invoked my framework which starts at InitialViewController and proceeds to SignInViewController.

When SignInViewController is displayed I paused the program execution in Xcode.Image1

The problem is I’m able to step into my framework classes while debugging in test project using below statement: Image2

(lldb) po [[[[UIApplication sharedApplication] keyWindow] rootViewController] visibleViewController]

<SignInViewController: 0x7fc225202490>

I’m also able to change the property values of SignInViewController: Image3

(lldb) po [[[[[UIApplication sharedApplication] keyWindow] rootViewController] visibleViewController] setGXIdentifier:@"AXSDF"]

AXSDF

I sell this framework to my customers and other developers, So I want to

1. Prevent them from debugging my framework in their Xcode projects.
2. Prevent View debugging on viewcontrollers of my framework.
3. Prevent changing property values of my viewcontrollers from debugging console.

I tried setting Generate Debug Symbols to NO. (which does not solve the issue)

I’m looking for a way to disable debugging on my framework.(Btw, I'm using Xcode 9.2)
