+## SwiftUI
+
+You can pick an image or images using SwiftUI by presenting a sheet with `FMSwiftUIImagePicker`
+
+If you want to select multiple images, then simply pass a binding to an array of `UIImage`
+
+```swift
+struct ContentView: View {
+    @State var image:UIImage?
+    @State var showPicker:Bool = false
+
+    var body: some View {
+        VStack {

+                    .resizable()
+                    .frame(width:100,height:100)
+            }
+
+            Button("Pick a Photo") {

 ## Customization
 ### Custom filter
 You can freely create your own filter by implementing the `FMFilterable` protocol.
