SwiftUI Image Viewer

An Image Viewer built with SwiftUI.

Installation

Swift Package Manager

The Swift Package Manager is a tool for managing dependencies in Swift projects. It is included in Swift 3.0 and above, and is the recommended way to install SwiftUI Image Viewer.

Add the following to your dependencies in your Package.swift file:

dependencies: [
    .package(url: "https://github.com/opacicmarko/swiftui-image-viewer.git", from: "0.1.0")
]

Usage

Simply import the ImageViewer module and use the ImageViewer view where necessary. For example, you could use the ImageViewer in a sheet:

import SwiftUI
import ImageViewer

struct SimpleExample: View {
    let image = Image("Waterfall")
    @State private var isImagePreviewPresented: Bool = false

    var body: some View {
        VStack {
            Button("Tap me to show image preview!") {
                isImagePreviewPresented = true
            }
        }
        .fullScreenCover(isPresented: $isImagePreviewPresented) {
            ImageViewer(
                image: image,
                onCloseTap: {
                    isImagePreviewPresented = false
                }
            )
        }
    }
}

There is also an ImagePreviewViewModifier to make it easier to view your image in a sheet or fullScreenCover:

struct ImagePreviewExample: View {
    @State private var previewImage: Image?

    var body: some View {
        VStack {
            Button("Tap me to show image preview!") {
                previewImage = Image("Waterfall")
            }
        }
        .imagePreview(image: $previewImage, presentationStyle: .sheet)
    }
}
