I fixed by selecting and deselecting target membership of the problematic file in the file inspector in Xcode

How to solve this?
Problem solved by removing the "-ObjC" linker flag.
In My App we need to add Following SDKs:
Pollfish
PrintIO
But I face a following
duplicate symbol _VERSION in:
/MyAppPath/Library/PrintIO/PrintIO.framework/PrintIO(BTEncryption.o)
/MyAppPath/pollfish.framework/pollfish ld: 1 duplicate symbol for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Both are frameworks.
If I remove one framework then My app works fine. But I need to add both things.

This was just after creating "PrintAdventureMenuViewController" class. So it is currently empty. "AdventureTypeMenuViewController" is not empty. It is populated with views other code.
My problem was that in the AdventureTypeMenuViewController.m file I used the import statement...
#import "PrintAdventureMenuViewController.m"
rather than...
#import "PrintAdventureMenuViewController.h"
I have following log in log console.How can I get rid of this?

Is Stepped_Slider_Bar your custom view? Trying to declare the _DeviceSystemMajorVersion with a prefix:
// Stepped_Slider_Bar.m
#define SteppedSliderBar_DeviceSystemMajorVersion xxxx
