Introduction

SnapshotTesting is a delightful snapshot testing library for Swift by Point-Free. A snapshot test captures the output of a value, such as a rendered view controller, a SwiftUI view, a URL request or a data model, and compares it with a reference stored on disk. Its README explains that when an assertion first runs, it records the reference and fails, printing the file path; later runs compare against that reference.

The key idea is snapshot strategies: the same assertSnapshot(of:as:) function can capture .image (with device configurations, traits and precision options), .recursiveDescription, .dump, .json, .lines and many more, and you can write custom strategies. Recording is controlled per assertion (record: .all) or for a scope with withSnapshotTesting(record:), including at the Swift Testing suite level. It works with XCTest and Swift Testing (@Test), supports UIKit, SwiftUI and AppKit, and includes inline snapshot testing for text. Version 1.19.7 was released on 21 October 2026.

The source code is at pointfreeco/swift-snapshot-testing on GitHub under the MIT licence, with about 4,400 stars; the most recent commit was on 21 October 2026.

Features

1. Many strategies: Images, text, JSON, dumps and custom formats.
2. Any value: Snapshot views, requests, models and more.
3. Scoped recording: Re-record per assertion or per scope.
4. XCTest and Swift Testing: Works with both frameworks.

Pros

1. Free to use: Open source under the MIT licence, so the core tool costs nothing to use.
2. Actively maintained: The repository had commits as recent as 21 October 2026.
3. Community: About 4,400 GitHub stars.

Cons

1. Image flakiness: Image snapshots can differ across simulators and OS versions; pin devices.
2. Repository size: Many image references increase repository size.

Usage and Links (Example)

import SnapshotTesting

struct CheckoutViewTests {
    @Test func checkoutLayout() {
        let vc = CheckoutViewController(order: .sample)
        assertSnapshot(of: vc, as: .image(on: .iPhone13))
    }

    @Test func requestShape() {
        assertSnapshot(of: API.createOrder(.sample), as: .raw)
    }
}
