Crash on [UICollectionView cellForItemAtIndexPath]

[xv-sufiyan-yasa]

Rerror message:

Fatal Exception: NSInternalInconsistencyException
Expected dequeued view to be returned to the collection view in preparation for display. When the collection view's data source is asked to provide a view for a given index path, ensure that a single view is dequeued and returned to the collection view. Avoid dequeuing views without a request from the collection view. For retrieving an existing view in the collection view, use -[UICollectionView cellForItemAtIndexPath:] or -[UICollectionView supplementaryViewForElementKind:atIndexPath:]. Dequeued view: <IBGPickerCollectionViewCell: 0x13ac61200; baseClass = UICollectionViewCell; frame = (94.3333 467.667; 92.5 92.5); clipsToBounds = YES; layer = <CALayer: 0x3025eb1e0>>; Collection view: <UICollectionView: 0x139714e00; frame = (0 0; 375 812); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x3031b22e0>; backgroundColor = <UIDynamicProviderColor: 0x3027001e0; provider = <NSMallocBlock: 0x302c69c80>>; layer = <CALayer: 0x302213ec0>; contentOffset: {0, -90.666666666666671}; contentSize: {375, 560}; adjustedContentInset: {94, 0, 44, 0}; layout: <UICollectionViewFlowLayout: 0x1397dd400>; dataSource: <IBGPickerDataSource: 0x303692240>>

Thank you for reporting this. Based on the information provided, this appears to be an internal issue within your application and is not related to the Instabug SDK. Please feel free to reach out if you find any evidence that suggests otherwise.

Thank you for the response @mohasalahh

I suggested that this is related to Instabug due to the following evidence:

1. My application does not use UICollectionView
2. The error message above ( in my original message ), hints the following 2 classes which is unknown to us IBGPickerCollectionViewCell and IBGPickerDataSource
