I’m seeing a consistent Instruments error after recording a SwiftUI profile:
“Failed to stop recording session: Data Providers emitted errors: Required”
The recording itself starts and runs normally. The error appears only after I stop recording, while Instruments is processing the trace. No profiling results are produced.
Environment:
- Xcode 27.0 beta 5 (27A5237l)
- Instruments 27.0 (27A5237l)
- Physical iOS device running the latest beta
I can reproduce this consistently using the SwiftUI template. I’ve also tried updating Instruments and restarting the tools, but the issue remains.
Expected: The trace finishes processing and displays the collected data.
Actual: Processing fails with the data-provider error above.
