treatWarning(_:as:_:)

Controls how a specific Swift compiler warning is treated during compilation.

Declaration

static func treatWarning(_ name: String, as level: WarningLevel, _ condition: BuildSettingCondition? = nil) -> SwiftSetting

Parameters

  • name:

    The name of the specific warning to control.

  • level:

    The treatment level for the warning (.warning or .error).

  • condition:

    A condition that restricts the application of the build setting.

Discussion

Use this setting to specify whether a particular warning should be treated as a warning (default behavior) or as an error. This is equivalent to passing -Werror or -Wwarning followed by the warning name to the Swift compiler.

This setting allows for fine-grained control over individual warnings. To control all warnings at once, use treatAllWarnings(as:_:) instead.
