Thanks!

## Installation: 

It requires iOS 13 and Xcode 11!

In Xcode got to `File -> Swift Packages -> Add Package Dependency` and paste inthe repo's url: `https://github.com/AppPear/SwiftUI-PullToRefresh`  

## Usage: 

You need to add `RefreshableNavigationView(title: String, action: () -> Void, content: () -> View)` to your View. Title is the navigationView title, and the action takes the refresh function. RefreshableNavigationView already encapsulates a List() so in the content you only need to define your cells. If you want TableViewCellSeparators don't forget to add a `Divider()` at the bottom of your cell.

Example: 

```swift

import SwiftUIPullToRefresh

struct ContentView: View {

    @State var numbers:[Int] = [23,45,76,54,76,3465,24,423]

    

    var body: some View {

        RefreshableNavigationView(title: "Numbers", action:{

            self.numbers = self.generateRandomNumbers()

        }){

            ForEach(self.numbers, id: \.self){ number in

                VStack(alignment: .leading){

                    Text("\(number)")

                    Divider()

                }

            }

        }

    }

    

    func generateRandomNumbers() -> [Int] {

        var sequence = [Int]()

        for _ in 0...30 {

            sequence.append(Int.random(in: 0 ..< 100))

        }

        return sequence

    }

}

```
