EXC_BAD_ACCESS KERN_INVALID_ADDRESS in Swift and iPhone 5

I just launched the app and I have an issue with iPhone 5 and 5c and iOS 10.3.3 (only).

enter image description here

I really don't understand the problem, even with the Crashlytics report:

enter image description here

The problem seems to come from this line:

@objc UserProfilViewController.collectionView(UICollectionView, layout : UICollectionViewLayout, sizeForItemAtIndexPath : IndexPath) -> CGSize

This is my code:

// Cell size
   func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: IndexPath) -> CGSize {

      let size: CGSize
      if cellIsNull == false {
         size = CGSize(width: self.view.frame.size.width * 0.47, height: self.view.frame.size.width * 0.47)
      } else {
         size = CGSize(width: self.view.frame.size.width, height: self.view.frame.size.width * 0.47)
      }
      return size
   }

If I run the app on the simulator (with an iPhone 5), the app is not crashing, and I don't have iPhone 5 so I don't test it.

Call it a coincidence. I asked a similar question few hours back. Not same but similar.
The solution is to put @objc in front of function definition. So function should be like : 

@objc func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: IndexPath) -> CGSize { 
....  

}

The main thing to notice is that the crash is random. I myself haven't received this yet. There might be a possibility that it depends on the iOS or indirectly, Swift version.
