This message indicates a problem with the configuration required to deploy an iOS application to a physical device or submit it to the App Store. The Integrated Development Environment (IDE) is unable to locate the necessary digital identities and configuration files that authorize the distribution of the application. These profiles link a developer’s identity, a specific application, and permitted devices, creating a secure chain of trust.
The presence of properly configured code signing is crucial for the integrity and security of the iOS ecosystem. These profiles ensure that only authorized developers can distribute applications, preventing unauthorized modifications and malware distribution. The historical context stems from Apple’s emphasis on a controlled and secure app distribution model. This system, while sometimes perceived as restrictive, provides a significantly safer user experience by limiting the attack surface.
