I have a Tabbar which is created by SwiftUI, but I use different images for different status of selected Tabbar(selected and unselected), how can I do that. I tried to change image name in TabView1().onAppear() { tabImageName1 = "image1_active" tabImageName2 = "image2" tabImageName3 = "image3" tabImageName4 = "image4" } seems this not worked, and I think it's not so elegant, how can I change the image rightly, do we have better ways to do thing like this?

I need to create a section header for a tableview, and I don't want to create it in single Xib, I added one in storyboard, but the header need some customization, so I create a file looks like this: class CustomizedTipsView: UITableViewHeaderFooterView {     @IBOutlet weak var tipTitle: UILabel!     @IBOutlet weak var tipContent: UILabel! } And I want to use the header in viewForHeaderInSection func like this: if let header = tableView.dequeueReusableHeaderFooterView(withIdentifier: "CustomizedTipsView") as? CustomizedTipsView {             header.tipTitle.text = "1"             header.tipContent.text = "2" } if I register the cell, it crash, if not, the cell always returns nil. //crash mainTableView.register(UINib(nibName: "CustomizedTipsView", bundle: nil), forHeaderFooterViewReuseIdentifier: "CustomizedTipsView") //crash too mainTableView.register(CustomizedTipsView.self, forHeaderFooterViewReuseIdentifier: "CustomizedTipsView") Do I have to use the UITableViewCell instead of simple CustomizedTipsView for view from storyboard? Thank you for your help!
