CI: wait for the iOS simulator before testing - #30

Conversation
On a fresh macos-26 runner the simulator service can start late. xcodebuild then lists no simulators at all and the iOS job fails with "Unable to find a device matching the provided destination specifier" after its own 60-second wait (Perfect-SQLite #29, second attempt; a retry passed). This matches actions/runner-images#12948. Before testing, poll xcodebuild -showdestinations for the iPhone 17 for up to 5 minutes. Each round first runs simctl list, the workaround from that issue, which makes the service refresh its runtimes. xcodebuild's errors stay in the log, so a package-resolution failure isn't hidden. The test also gets -destination-timeout 120 in case the device drops out again between the check and the run. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Summary
Fixes an occasional iOS CI failure: "Unable to find a device matching the provided destination specifier". On a fresh macos-26 runner the simulator service sometimes starts late. xcodebuild then waits 60 seconds, lists no simulators at all (only placeholders), and fails. This happened on #29's second attempt, and a retry passed. It matches actions/runner-images#12948.

Locally, I ran the step under the runner's shell (
bash -e). The success path exits as soon as the iPhone 17 is listed. The timeout path reports and exits 1. CRUD's iOS tests pass 179/179 with the new flag. The real test is this PR's CI on GitHub. Per the issue thread, this makes the flake rarer but doesn't guarantee it's gone.🤖 Generated with Claude Code
