The occurrence of a build process termination during iOS application development, specifically signaled by error code 65, indicates a general failure within the Xcode build system. This error suggests that a command invoked during the compilation, linking, or packaging phases returned a non-zero exit code, signaling an issue that prevented the successful creation of the application bundle. For instance, a script within the build process might fail due to an incorrect path, missing dependency, or permission issue, leading to this error.
Understanding and resolving this error is critical for maintaining development velocity and ensuring timely app releases. Such failures interrupt the iteration cycle, delaying testing and deployment. Historically, code 65 has often been associated with issues ranging from environment configuration problems and code-signing irregularities to third-party library conflicts and resource access violations. Addressing these causes reduces development downtime and improves overall project stability.
