Access an IBOutlet from another class

I have 2 swift files the one is my HomeViewController and the second is my EventCollectionViewCell. In the second one I have an IBOutlet = informationView :UIView and I want to access this from the HomeViewController.

Is there any way ? Thank you in advance, KS

Well I suppose that in HomeViewController you have a UICollectionView and that acts as a datasource for it, then in your collectionView dataSource you can make:

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cellIdentifier", forIndexPath: indexPath) as! EventCollectionViewCell

    //Here you can access the IBOulets define in your cell
    cell.informationView.backgroundColor = UIColor.greenColor()

    return cell
}

Edit:

Problem: When you tap on a cell you want to show an Overlay inside the cell.

Solution: You need you data model to maintain the state, if it's active or not (the informationView), suppose that ItemCell is my model (in your case Event can be):

class ItemCell{
    var active:Bool = false
}

In the collectionView:cellForRowAtIndexPath:, you're going to check the current status of your model, and base on that, show or hide that overlay:

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cellIdentifier", forIndexPath: indexPath) as! EventCollectionViewCell

    let event = self.data[indexPath.row]
    //Here you can access the IBOulets define in your cell
    cell.informationView.hidden = !event.active

    return cell
}

Then as a final step, every time you select a cell (func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) method), you're going to update the status of your model:

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath){
    let event = self.data[indexPath.row]
    event.active = !event.active
    collectionView.reloadData()
}

Declare a property for that cell and access IbOutlets through that object.

@property (nonatomic, strong) MSSearchHeaderView *searchHeaderView;

if (self.searchHeaderView.searchTextField.text.length <= 0) {

        self.searchHeaderView.clearButton.hidden = YES;

}else{

        self.searchHeaderView.clearButton.hidden = NO;

}

Follow what Jose has answered and if you are creating the cell in the interface builder. Set the class of the cell in Identity Inspector to EventCollectionViewCell and set the cell identifier to "cellIdentifier" that Jose has specified.
