QGrid: The missing SwiftUI collection view.

“Build Platforms Swift Package Manager License: MIT Twitter: @karolkulesza

QGrid is the missing SwiftUI collection view. It uses the same approach as SwiftUI's List view, by computing its cells on demand from an underlying collection of identified data.

🔷 Requirements

      macOS 10.15+
      Xcode 11.0
      Swift 5+
      iOS 13+       tvOS 13+

🔷 Installation

QGrid is available via Swift Package Manager.

Using Xcode 11, go to File -> Swift Packages -> Add Package Dependency and enter https://github.com/Q-Mobile/QGrid

🔷 Usage

✴️ Basic scenario:

In its simplest form, QGrid can be used with just this 1 line of code within the body of your View, assuming you already have a custom cell view:

struct PeopleView: View {
  var body: some View {
    QGrid(Storage.people, columns: 3) { GridCell(person: $0) }
  }
}   

struct GridCell: View {
  var person: Person

  var body: some View {
    VStack() {
      Image(person.imageName)
        .resizable()
        .scaledToFit()
        .clipShape(Circle())
        .shadow(color: .primary, radius: 5)
        .padding([.horizontal, .top], 7)
      Text(person.firstName).lineLimit(1)
      Text(person.lastName).lineLimit(1)
    }
  }
}

✴️ Customize the default layout configuration:

You can customize how QGrid will layout your cells by providing some additional initializer parameters, which have default values:

struct PeopleView: View {
  var body: some View {
    QGrid(Storage.people,
          columns: 3,
          columnsInLandscape: 4,
          vSpacing: 50,
          hSpacing: 20,
          vPadding: 100,
          hPadding: 20) { person in
            GridCell(person: person)
    }
  }
}   

🔷 Example App

📱QGridTestApp directory in this repository contains a very simple application that uses QGrid. Open QGridTestApp/QGridTestApp.xcodeproj and either use the new Xcode Previews feature or just run the app.

🔷 QGrid Designer

📱QGridTestApp contains also the QGrid Designer area view, with sliders for dynamic run-time configuration of the QGrid view (with config option to hide it). Please refer to the following demo executed on the device:

🔷 Roadmap / TODOs

Version 0.1.1 of QGrid contains a very limited set of features. It could be extended by implementing the following tasks:

     ☘️ Parameterize spacing&padding configuration depending on the device orientation
     ☘️ Add the option to specify scroll direction
     ☘️ Add content-only initializer to QGrid struct, without a collection of identified data as argument (As in SwiftUI’s List)
     ☘️ Add support for other platforms (watchOS)
     ☘️ Add Stack layout option (as in UICollectionView)
     ☘️ Add unit/UI tests
     ☘️ ... many other improvements
