Binding to UICollectionView not initially configuring collection view

[AnthonyMDev]

When I bind an ObservableCollection to a UICollectionView, the collection view is not being set up until I make some changes to my collection. The initial values of my collection are not being loaded to the collection view.

I've noticed in debugging that the RKCollectionViewDataSource.sourceCollection is empty, even though the observableCollection has items in it.

This is fixed by removing the skip(1) from observableCollection.skip(1).observe(on: ImmediateOnMainExecutionContext) { [weak self] event in on line 76 of UICollectionView.swift.

Why are we skipping the 1st observation anyways?

I just noticed that, though the sourceCollection is printing to the debugger as {}, sourceCollection.count equals 1. So I'm not sure what is going wrong here.

That does not sound good. I'll check it out :) Thanks for reporting!

Let me know if you need a demo project I can try to set one up!

@srdanrasic After more testing, I've found multiple different issues with this through my unit testing. I'm getting exceptions thrown when trying to insert new items into my ObservableCollection and when I try to move them around in my proxy data source's "didMove" implementation.

All of these issues disappear as soon as I remove skip(1).

@AnthonyMDev those messages smell on some email malware 😟

Yeah not sure what's that's about. Looking into it. :/
