provisioningprofiler

Provisioningprofiler is a software tool and library designed to analyze and audit iOS provisioning profiles used for code signing. It helps developers, teams, and organizations verify that profiles are valid, properly configured, and aligned with their signing certificates and app identifiers.

Provisioning profiles contain an App ID, certificates, device lists, and entitlements. The profiler parses the profile data, extracting fields such as expiration date, team identifier, bundle ID patterns, supported devices, and entitlements. It distinguishes profile types including development, Ad Hoc, App Store, and enterprise, and checks how these types are intended to be used within a project.

Key capabilities typically include validity checks (expiration and revocation), consistency checks (certificate versus profile, App ID match, device list alignment), and comprehensive reporting. Many implementations generate both human-readable summaries and machine-readable outputs (such as JSON) suitable for integration into continuous integration and delivery pipelines. They may also provide guidance on remediation, such as renewing certificates, updating device lists, or adjusting entitlements to avoid signing errors.

Formats and data handling revolve around provisioning profile files, commonly stored in binary plist format with a .mobileprovision extension or converted to readable plist form. The profiler is designed to extract and interpret these data structures, and may interface with related signing artifacts such as certificates stored in the keychain. When credentials are available, some tools can perform additional checks against developer accounts to verify certificate validity and profile integrity.

In practice, provisioningprofilers are used to support automated signing workflows, audits, and renewal planning within iOS development environments, often as components of broader toolchains that include Xcode, fastlane, or other CI systems. They complement, rather than replace, issuer policies and manual review processes.
