extension Snapshotting where Value == UIViewController, Format == UIImage has a method:

public static func image(
    on config: ViewImageConfig,
    precision: Float = 1,
    perceptualPrecision: Float = 1,
    size: CGSize? = nil,
    traits: UITraitCollection = .init()
    )
    -> Snapshotting

You can pass a CGSize object to that method with the @1x pixel resolution of an iPhone.

And you can call it through

public func assertSnapshot<Value, Format>(
  matching value: @autoclosure () throws -> Value,
  as snapshotting: Snapshotting<Value, Format>,
  named name: String? = nil,
  record recording: Bool = false,
  timeout: TimeInterval = 5,
  file: StaticString = #file,
  testName: String = #function,
  line: UInt = #line
  )

via the as parameter.

Example:

as: .image(
    ...
    size: CGSize(width: ..., height: ...),
    ...
)
