              Extra unneeded rendering issue with Custom Grid View in SwiftUI

              Asked 2021-Dec-27 at 07:23

              I am making a CustomGridView without using Apple Grid, my codes works fine but it has an extra rendering issue when I add new row! As long as I see in my codes, if I add new row, Xcode should render just for new Items! But in the fact it renders all the items! which I can not find the issue! I am okay if Xcode renders all Items if I add new column, because the size put effect on every single Item, but with adding row, there is no general effect on items!

              import SwiftUI
              
              struct GridItemView: View {
              
                  let rowItem: GridItemRowType
                  let columnItem: GridItemColumnType
                  let string: String
                  let size: CGFloat
                  @State private var color: Color = Color.randomColor
              
                  init(rowItem: GridItemRowType, columnItem: GridItemColumnType, size: CGFloat) {
                      self.rowItem = rowItem
                      self.columnItem = columnItem
                      self.size = size
                      self.string = "(" + String(describing: rowItem.index) + "," + String(describing: columnItem.index) + ")"
                  }

              You need to make cell view equatable, so SwiftUI would know if it should be re-rendered.

              Tested with Xcode 13.2 / iOS 15.2

              demo

              struct GridItemView: View, Equatable {
                  // The `string` property is used just for demo, in real you 
                  // need some unique identifier which represents that view
                  // has same content
                  static func == (lhs: GridItemView, rhs: GridItemView) -> Bool {
                      lhs.string == rhs.string
                  }
              
              // ... other code
              }
              

              and then inside grid use it as

              ForEach(gridItemColumn) { columnItem in
              
                  EquatableView(content: GridItemView(rowItem: rowItem, 
                                                   columnItem: columnItem, size: size))
              
              }

              Install CustomGridView

              You can download it from GitHub.
              You can use CustomGridView like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the CustomGridView component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
