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

## 🔷 Requirements

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;✅ macOS 10.15+  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;✅ Xcode 11.0  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;✅ Swift 5+  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;✅ iOS 13+  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;✅ tvOS 13+

## 🔷 Installation

`QGrid` is available via [Swift Package Manager](https://swift.org/package-manager).

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

```Swift
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:

```swift
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.


<center>
<table bordercolor=white>
  <tr>
    <th>
      <img src="QGridTestApp/Screenshots/People1.png" width="400"/>
    </th>
    <th>
      <img src="QGridTestApp/Screenshots/People2.png" width="400"/>
    </th>
  </tr>
</table>
<table bordercolor=white>
  <tr>
	 <th>
    	<img src="QGridTestApp/Screenshots/People3.png" width="800"/>
    </th>
  </tr>
  <tr>
	 <th>
    	<img src="QGridTestApp/Screenshots/People4.png" width="800"/>
    </th>
  </tr>
</table>
</center>

## 🔷 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:

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