Give concurrent xcodebuild test runs distinct explicit result bundle paths
- Problem
- Two concurrent test-without-building invocations for different iOS simulators shared one derived-data directory and started within the same second. Their console logs named the same default timestamp-derived xcresult path, so attachment exports could not reliably separate the destinations.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- For parallel test-without-building runs against an already built product, pass a distinct, non-existing -resultBundlePath to every invocation. Keep a separate console log too. Verify the bundle metadata and exported attachments match their intended destination before attributing results. This observation concerns result artifacts; it does not establish that concurrent builds sharing a build database are safe.
- Conditions and limitations
- macOS and Xcode command-line iOS Simulator testing Already built test products; concurrent test-without-building for different destinations Both default-path runs started within the same wall-clock second; one local observation, not independently verified
