My app keeps crashing in 2 different places in any version that is lower than iOS 11.
One of the crashes is an EXC_BREAKPOINT that breaks on the appDelegate class defining line - class AppDelegate: UIResponder, UIApplicationDelegate {}
While the other crashes with EXC_BREAKPOINT on a simple segmentedControl?.removeAllSegments() (and yes I checked if the segmentedControl is empty; its not).
Whats interesting is that I never had this issue so much as 2/3 weeks ago, and I know for a fact that I changed no line of code from those 2 places.
The debugger just says this : "-[UILayoutGuide nsli_superitem]: message sent to deallocated instance 0x600000386db0"
Here is the stack trace:

Any information on this would be helpful, currently exploring all options. If you need more information on this, post a comment and I will get back to you instantly. Thanks
Stupid, but I was finally able to figure it out.
I found that in my Interface Builder Document in storyboard, my deployment target was set at 11.0 for the pages I was trying to load.
I hope this helps someone :)
