15	## PhotosPicker (SwiftUI, iOS 16+)
16
17	`PhotosPicker` is the native SwiftUI replacement for `UIImagePickerController`. It runs out-of-process, requires no photo library permission for browsing, and supports single or multi-selection with media type filtering.
18
19	### Single Selection
20
21	```swift
22	import SwiftUI
23	import PhotosUI
24
25	struct SinglePhotoPicker: View {
26	@State private var selectedItem: PhotosPickerItem?
27	@State private var selectedImage: Image?
28
29	var body: some View {
30	VStack {
31	if let selectedImage {
32	selectedImage
33	.resizable()
34	.scaledToFit()
35	.frame(maxHeight: 300)
36	}
37
38	PhotosPicker("Select Photo", selection: $selectedItem, matching: .images)
39	}
40	.onChange(of: selectedItem) { _, newItem in
41	Task {
42	if let data = try? await newItem?.loadTransferable(type: Data.self),
43	let uiImage = UIImage(data: data) {
44	selectedImage = Image(uiImage: uiImage)
45	}
46	}
47	}
48	}
49	}
50	```
51
52	### Multi-Selection
53
54	```swift
55	struct MultiPhotoPicker: View {
56	@State private var selectedItems: [PhotosPickerItem] = []
57	@State private var selectedImages: [Image] = []
58
59	var body: some View {
60	VStack {
61	ScrollView(.horizontal) {
62	HStack {
63	ForEach(selectedImages.indices, id: \.self) { index in
64	selectedImages[index]
65	.resizable()
66	.scaledToFill()
67	.frame(width: 100, height: 100)
68	.clipShape(.rect(cornerRadius: 8))
69	}
70	}
71	}
72
73	PhotosPicker(
74	"Select Photos",
75	selection: $selectedItems,
76	maxSelectionCount: 5,
77	matching: .images
78	)
79	}
80	.onChange(of: selectedItems) { _, newItems in
81	Task {
82	selectedImages = []
83	for item in newItems {
84	if let data = try? await item.loadTransferable(type: Data.self),
85	let uiImage = UIImage(data: data) {
86	selectedImages.append(Image(uiImage: uiImage))
87	}
88	}
89	}
90	}
91	}
92	}
93	```
94
95	### Media Type Filtering
96
97	Filter with `PHPickerFilter` composites to restrict selectable media:
98
99	```swift
100	// Images only
101	PhotosPicker(selection: $items, matching: .images)
102
103	// Videos only
104	PhotosPicker(selection: $items, matching: .videos)
105
106	// Live Photos only
107	PhotosPicker(selection: $items, matching: .livePhotos)
108
109	// Screenshots only
110	PhotosPicker(selection: $items, matching: .screenshots)
111
112	// Images and videos combined
113	PhotosPicker(selection: $items, matching: .any(of: [.images, .videos]))
114
115	// Images excluding screenshots
116	PhotosPicker(selection: $items, matching: .all(of: [.images, .not(.screenshots)]))
117	```
118
119	### Loading Selected Items with Transferable
120
121	`PhotosPickerItem` loads content asynchronously via `loadTransferable(type:)`. Define a `Transferable` type for automatic decoding:
122
123	```swift
124	struct PickedImage: Transferable {
125	let data: Data
126	let image: Image
127
128	static var transferRepresentation: some TransferRepresentation {
129	DataRepresentation(importedContentType: .image) { data in
130	guard let uiImage = UIImage(data: data) else {
131	throw TransferError.importFailed
132	}
133	return PickedImage(data: data, image: Image(uiImage: uiImage))
134	}
135	}
136	}
137
138	enum TransferError: Error {
139	case importFailed
140	}
141
142	// Usage
143	if let picked = try? await item.loadTr
