The initializer uses this format’s [`parseStrategy`](/documentation/Foundation/Decimal/FormatStyle/parseStrategy) to parse the string. `lenient` A Boolean value that indicates whether the parse strategy should permit some discrepancies when parsing. Defaults to `true`. ## Discussion This initializer throws an error if the format style fails to parse the string into a decimal value. --- Copyright © 2026 Apple Inc.
