Apple Developers Inc is an independent resource for people who build for, and work on, Apple platforms. We publish clear, tested fixes for the errors and problems developers and power users actually run into.
What we cover
- Xcode errors: build failures, code signing, provisioning, simulators and archive/upload problems
- Swift & SwiftUI: language features and frameworks explained with working code
- App Store & TestFlight: App Store Connect, review rejections and distribution
- iOS and macOS fixes: problems that show up after updates, with step-by-step solutions
- Developer updates: what changed in new SDK and tool releases and what it means for your apps
How we write
Every guide starts from a real problem: an error message, a release note, or an issue reported by developers. We explain why it happens, give the fix in order of what is most likely to work, and update articles when new versions change the answer.
The site is run by a working full-stack developer. If something in a guide is wrong or out of date, please tell us and we will fix it.
