# LaunchCodeRequirement A lightweight code requirement that you use to evaluate the executable for a launching process. ``` struct LaunchCodeRequirement ``` ## Overview If you set a `LaunchCodeRequirement` object for a launching process and the executable doesn’t satisfy the requirement, the operating system doesn’t run the process and creates a crash report instead. [`LaunchCodeRequirement`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement) objects can only be built using constraints that conform to the [`LaunchConstraint`](/documentation/LightweightCodeRequirements/LaunchConstraint) protocol. Note that [`LaunchCodeRequirement`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement) are applied to processes. If a launch requests execution of ‘#!’ script, the launch constraint will be applied to the interpreter. For example a script with the following ‘#!’ will apply a launch constraint to bash. ```bash #! /bin/bash ``` if the ‘#!’ is instead: ```bash #! /usr/bin/env python ``` Then the launch constraint is applied to env. ## Topics ### Initializers [`init(ProcessCodeRequirement) throws`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement/init(_:)-5fh0u) Convert a [`ProcessCodeRequirement`](/documentation/LightweightCodeRequirements/ProcessCodeRequirement) to a [`LaunchCodeRequirement`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement) if possible. [`init(OnDiskCodeRequirement) throws`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement/init(_:)-6hixy) Convert a [`OnDiskCodeRequirement`](/documentation/LightweightCodeRequirements/OnDiskCodeRequirement) to a [`LaunchCodeRequirement`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement) if possible. [`init(from: any Decoder) throws`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement/init(from:)) Create a new instance by decoding from the given decoder ### Instance Methods [`func encode(to: any Encoder) throws`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement/encode(to:)) Encodes this value into the given encoder ### Type Methods [`static func allOf(requirement: () -> [any LaunchConstraint]) throws -> LaunchCodeRequirement`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement/allOf(requirement:)) Create a [`LaunchCodeRequirement`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement) that requires matching all of the provided constraints. [`static func anyOf(requirement: () -> [any LaunchConstraint]) throws -> LaunchCodeRequirement`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement/anyOf(requirement:)) Create a [`LaunchCodeRequirement`](/documentation/LightweightCodeRequirements/LaunchCodeRequirement) that requires matching any of the provided constraints. ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Encodable`](/documentation/Swift/Encodable) [`Equatable`](/documentation/Swift/Equatable) [`Decodable`](/documentation/Swift/Decodable) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
