selectItem error!

Calling selectItem immediately after reloadData will crash

Thread 1: "Attempted to scroll the collection view to an out-of-bounds item (4) when there are only 0 items in section -1. Collection view: <FSPagerViewExample.FSPagerCollectionView: 0x10380ea00; baseClass = UICollectionView; frame = (0 0; 0 0); clipsToBounds = YES; gestureRecognizers = <NSArray: 0x280105a40>; backgroundColor = UIExtendedGrayColorSpace 0 0; layer = <CALayer: 0x280fcb7e0>; contentOffset: {0, 0}; contentSize: {0, 0}; adjustedContentInset: {0, 0, 0, 0}; layout: <FSPagerViewExample.FSPagerViewLayout: 0x102b04a90>; dataSource: <FSPagerViewExample.FSPagerView: 0x102b0e560; frame = (0 70; 1080 556); autoresize = RM+BM; layer = <CALayer: 0x280fcb440>>>."

Can you provide steps to re-produce?

Hi, I have also encountered this issue, refer to the following steps to reproduce the problem.

1. Download FSPagerView own example
2. Add the following code to TransformerExampleViewController:

override func viewDidLoad() {
        super.viewDidLoad()
        
        pagerView.reloadData()
        pagerView.selectItem(at: 2, animated: false)
}

3. run the project, click on Transformer Example and it will crash, then you will see the crash message.

Me too!
pagerView.selectItem(at:animated:) 传最后一个的index，即count - 1，必崩！
