ultimatevegance commented 4 years ago

uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array'


- (IBPNSCollectionLayoutItem *)layoutItemAtIndexPath:(NSIndexPath *)indexPath {
    NSArray<IBPCollectionCompositionalLayoutSolverResult *> *results = self.results;
    IBPCollectionCompositionalLayoutSolverResult *result = [results objectAtIndex:indexPath.item % results.count];
    return result.layoutItem;
}

I think #136 will resolve that issue
