HtmlToPdf provides an easy-to-use interface for concurrently printing HTML to PDF on iOS and macOS.
- Convert HTML strings to PDF documents on both iOS and macOS.
- Lightweight and fast: it can handle thousands of documents quickly.
- Customize margins for PDF documents.
- Swift 6 language mode enabled
Print to a file url:
try await "<html><body><h1>Hello, World 1!</h1></body></html>".print(to: URL(...))Print to a directory with a file title.
let directory = URL(...)
let html = "<html><body><h1>Hello, World 1!</h1></body></html>"
try await html.print(title: "file title", to: directory)Print a collection to a directory.
let directory = URL(...)
try await [
html,
html,
html,
....
]
.print(to: directory)The package includes a test that prints 1000 HTML strings to PDFs in ~2.6 seconds (using UIPrintPageRenderer on iOS or Mac Catalyst) or ~12 seconds (using NSPrintOperation on MacOS).
@Test func collection() async throws {
[...]
let count = 1_000
try await [String].init(
repeating: "<html><body><h1>Hello, World 1!</h1></body></html>",
count: count
)
.print(to: URL(...))
[...]
}Optionally, you can invoke an overload that returns an AsyncStream<URL> that yields the URL of each printed PDF.
Note
You need to include the AsyncStream type signature in the variable declaration, otherwise the return value will be Void.
let directory = URL(...)
let urls: AsyncStream = try await [
html,
html,
html,
....
]
.print(to: directory)
for await url in urls {
Swift.print(url)
