Refresh

Refresh provides SwiftUI-native components for handling data refreshing and pagination within a ScrollView.

Key Components:

• RefreshHeader: Handles drop-down pull-to-refresh logic. It requires a binding to a refreshing state (refreshing:), an asynchronous or synchronous action to perform the reload, and a view builder to customize the refresh indicator UI.
• RefreshFooter: Handles scroll-up to load more logic. It requires a binding to a refreshing state (refreshing:), an action to load more data, and a view builder for the footer UI.
• .noMore(Bool): A modifier for RefreshFooter to indicate when no further data is available.
• .preload(offset: Int): A modifier for RefreshFooter to trigger the load-more action before the user reaches the absolute bottom, based on a pixel offset.
• .enableRefresh(): A modifier applied to the ScrollView to enable the refresh capabilities.

ScrollView {
    RefreshHeader(refreshing: $headerRefreshing, action: reload) {
        if self.headerRefreshing {
            Text("refreshing...")
        } else {
            Text("Pull to refresh")
        }
    }

    ForEach(items) { item in
        YourCell(item: item)
    }

    RefreshFooter(refreshing: $footerRefreshing, action: loadMore) {
        if self.noMore {
            Text("No more data !")
        } else {
            Text("refreshing...")
        }
    }
    .noMore(noMore)
    .preload(offset: 50)
}
.enableRefresh()
