why is content in UICollectionViewCell located incorrectly? - ios

Question

I have next code in controller, which set frame of UICollectionViewCell:
let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)
layout.itemSize = CGSize(width: self.view.frame.size.width / 3.8, height: self.view.frame.size.width / 3.8)
layout.minimumInteritemSpacing = 0
layout.minimumLineSpacing = 0
layout.scrollDirection = .vertical
devicesCollectionView.collectionViewLayout = layout
Chunk of code in delegate method, which call cell's method, which set data in it:
if let deviceCell = cell as? DevicesCollectionViewCell , let devices = room?.devices, let roomName = room?.roomName {
deviceCell.setDeviceInfoInCell(device: devices[indexPath.item], roomName: roomName, width: self.view.frame.size.width / 3.8)
}
chunk of code in cell's class:
self.frame = CGRect(x: self.frame.origin.x, y: self.frame.origin.y, width: width, height: width)
self.stateImageView.frame = CGRect(x: self.frame.origin.x + width - (width / 3), y: self.frame.origin.y, width: width / 3, height: width / 3)
self.lightImageView.frame = CGRect(x: self.frame.origin.x + 10, y: self.frame.origin.y + 10, width: width / 3, height: width / 3)
self.sensImageView.frame = CGRect(x: self.frame.origin.x + 10, y: self.frame.origin.y + 10, width: width / 5, height: width / 5)
self.humdityImageView.frame = CGRect(x: self.frame.origin.x + 10, y: self.frame.origin.y + sensImageView.frame.size.height + 15, width: width / 5, height: width / 5)
But when my CollectionView is showed, imageviews inside placed incorrectly, sometimes I didn't see them. Why they gets incorrect coordinates?
Screenshots: only one picture in one cell
and here icons goes anywhere:
Updating
according the comments I'm trying to use layoutIfNeeds and adding this method to my cell's class:
override func layoutSubviews() {
self.layoutIfNeeded()
self.stateImageView.layoutIfNeeded()
self.sensImageView.layoutIfNeeded()
self.humdityImageView.layoutIfNeeded()
self.lightImageView.layoutSubviews()
}
But it is don't solved my problem, and now labels goes anywhere too. Please help me. New screenShot:
