Analysis and Resolution of Missing Compliance Status in TestFlight
This technical paper provides an in-depth analysis of the 'Missing Compliance' warning that iOS developers encounter when uploading builds to TestFlight for internal testing. The paper examines the root cause—U.S. export compliance regulations for encryption technologies—and presents two primary solutions: for apps not using non-exempt encryption, adding the ITSAppUsesNonExemptEncryption key with value false in Info.plist resolves the issue; for apps with custom encryption, additional legal documentation and review are required. Detailed code examples and Xcode interface guidance help developers implement compliance configurations effectively.
