[graycreate]

Summary

• Merge code-quality.yml, ios-build-test.yml, and pr-validation.yml into a unified ci.yml
• All 6 jobs run in parallel with unified trigger conditions
• Reduces workflow file count from 3 to 1 for easier maintenance

Reference

Based on grayverse/ULPB-iOS#106

Test plan

• Verify all jobs trigger on PR
• Confirm jobs run in parallel

Pull request overview

This PR consolidates three separate GitHub Actions workflow files (code-quality.yml, ios-build-test.yml, and pr-validation.yml) into a single unified ci.yml workflow for improved maintainability. The consolidation preserves all 6 original jobs (lint, swiftformat, pr-size, check-commits, build-and-test, code-coverage) while unifying trigger conditions and adding concurrency control.

• Merges 3 workflow files into 1 unified CI workflow
• Enables all jobs to run in parallel with appropriate conditions
• Adds concurrency control to cancel outdated workflow runs

Variable name collision: the loop variable label on line 125 shadows the label variable defined on line 110. This will cause the size label calculation to be overwritten during the loop. Consider renaming the loop variable to something like existingLabel to avoid this conflict.

for (const existingLabel of labels.data) {
  if (existingLabel.name.startsWith('size/')) {
    await github.rest.issues.removeLabel({
      owner: context.repo.owner,
      repo: context.repo.repo,
      issue_number: pr.number,
      name: existingLabel.name
    });
  }
}

	for (const label of labels.data) {
	if (label.name.startsWith('size/')) {
	await github.rest.issues.removeLabel({
	owner: context.repo.owner,
	repo: context.repo.repo,
	issue_number: pr.number,
	name: label.name
	for (const existingLabel of labels.data) {

	issue_number: pr.number,
	name: existingLabel.name

Useless use of cat: The command cat coverage.json | jq can be simplified to jq '...' coverage.json which is more efficient and follows best practices by avoiding an unnecessary pipe.

COVERAGE=$(jq -r '.lineCoverage // 0' coverage.json | awk '{printf "%.2f", $1 * 100}')

Suggested change

	COVERAGE=$(cat coverage.json | jq -r '.lineCoverage // 0' | awk '{printf "%.2f", $1 * 100}')
	COVERAGE=$(jq -r '.lineCoverage // 0' coverage.json | awk '{printf "%.2f", $1 * 100}')
