App Center is your continuous integration, delivery and learning solution for iOS and macOS apps. Get faster release cycles, higher-quality apps, and the insights to build what users want.

The App Center SDK uses a modular architecture so you can use any or all of the following services:

1. App Center Analytics: App Center Analytics helps you understand user behavior and customer engagement to improve your app. The SDK automatically captures session count, device properties like model, OS version, etc. You can define your own custom events to measure things that matter to you. All the information captured is available in the App Center portal for you to analyze the data.

2. App Center Crashes: App Center Crashes will automatically generate a crash log every time your app crashes. The log is first written to the device's storage and when the user starts the app again, the crash report will be sent to App Center. Collecting crashes works for both beta and live apps, i.e. those submitted to the App Store. Crash logs contain valuable information for you to help fix the crash.

3. App Center Distribute: App Center Distribute lets your users install a new version of the app when you distribute it with App Center. With a new version of the app available, the SDK will present an update dialog to the users to either download or postpone the new version. Once they choose to update, the SDK will start to update your application. This feature is automatically disabled on versions of your app deployed to the Apple App Store. *Not available for macOS and tvOS.

4. App Center Push: App Center Push enables you to send push notifications to users of your app from the App Center portal. You can also segment your user base based on a set of properties and send them targeted notifications. *Not available for tvOS.

It is super easy to use App Center. Have a look at our get started documentation and onboard your app within minutes. Our detailed documentation is available as well.

We are looking forward to your contributions via pull requests.

All Objective-C files follow LLVM coding style (with a few exceptions) and are formatted accordingly. To format your changes, make sure you have the clang-format tool. It can be installed with Homebrew using the command brew install clang-format. Once you have installed clang-format, run ./clang-format-changed-files.sh from the repository root - this will format all files that have changes against the remote develop branch (it will also perform a git fetch).

App Center SDK support is provided directly within the App Center portal. Any time you need help, just log in to App Center, then click the blue chat button in the lower-right corner of any page and our dedicated support team will respond to your questions and feedback.
