sdkbump

Before you ship a build made with Xcode 27: sdkbump checks a native iOS, Flutter or React Native/Expo project for what the iOS 27 SDK changes, starting with the UIScene life cycle, and says which fix applies to each finding.

Guides

• Why it compiles and still crashes
• Native UIKit and SwiftUI apps
• Flutter: a custom AppDelegate and plugins
• React Native before 0.88 and Expo before SDK 58
• Native module authors: links and notifications at cold start

API

The command line is a thin layer over the package's exports, so the same checks run from JavaScript:

import { render, scan } from '@mcamdali/sdkbump';

const report = await scan('path/to/app');
console.log(report.verdict.text);
console.log(render(report, 'markdown'));
Copy

Start with scan and render; the JSON report is described by Report. Its schemaVersion is 0 until the layout is declared stable in 1.0. The rule data behind every finding is RuleData, loaded by loadRuleData.
