Hello Im having similar issues, however with Instrumenting a macOS application. Instruments + SwiftUI was working great with XCode 16.3 and macOS 15.5 I recently updated to macOS 15.7.2 and XCode 26.1.1 And now When I run my application via Product -> Profile (Command I) SwiftUI Template Run Instruments launches my app for a microsecond, and then fails with Failed to start the recording: Failed starting ktrace session. Some notes For my macOS target, i can only choose deferred mode for the Recorder Settings
