NSInternalInconsistencyException error in iOS 13.2.2 and Xcode 11.3.1 Beta

[anuranBarman]

Hi, I am using CarbonKit since long time but now after upgrading to iOS 13.2.2 it's crashing when the app is starting. The error is like below:

*** Assertion failure in UITraitCollection * _Nonnull _UIGetCurrentFallbackTraitCollection(void)(), /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKitCore/UIKit-3900.12.16/_UIFallbackEnvironment.m:91

libc++abi.dylib: terminating with uncaught exception of type NSException

I have seen #241 and #242 which is same error and comments said that upgrading to CarbonKit 2.3.1 will fix this. I upgraded my pod to the said version but the issue is still persisting. How do I fix this?

Upon debugging I found that the crash is happening at the time of doing

carbonTabSwipeNavigation = CarbonTabSwipeNavigation(items: self.tabNames, delegate: self)

When the delegate is being set it is crashing. When I put break points on the implementation of the constructor it is not reaching the breakpoint at all. What can be the meaning of this?

I have same issue please help asap.

I was facing the same issue. I removed the pod and added the CarbonKit.xcodeproj directly in the project. This fixed the crash.

@ermalkaleci Hey, it's not working with IOS 13 please kindly update the pod, i was trying to update into 2.3.1 but coco pod said this version is not compatible stay in the 2.2.2

Error Cocopod : [!] CocoaPods could not find compatible versions for pod "CarbonKit":
In Podfile:
CarbonKit (~> 2.3)
Error on Xcode : Assertion failure in UITraitCollection * _Nonnull _UIGetCurrentFallbackTraitCollection(void)()

Please provide the solution as soon as possible thanks for this CarbonKit

@arsadrahman
In this class CarbonTabSwipeNavigation.m. try to remove setting first view controller code from viewDidLoad and put it into viewWillAppear or viewDidAppear. It fixed crash for me.Because i added CarbonKit manually in my project.

@arjungupta0107 How to add CarbonKit Manually ?

[arjungupta0107]

@arsadrahman i mean you can drop CarbonKit files directly in to your project folder. Because i did not use cococapods etc..

@arjungupta0107 i have added CarbonKit manually in my project and doing the things which you have shared but still i face same error.
