Xamarin Forms – App Center: Show BuildID on iOS App


App center helps us to connect support git repositories (i.e GitHub, Bitbucket or VSTS)  and build the app for us either on every code commit or manually. It also sends notifications to users that are registered to it. It will also help us to run tests on the actual device and runs any unit tests in the project.

iOS and Android

App Center can be set up to build individual platforms projects.

APPCENTER_BUILD_ID is the App Center variable that contains BuildID, below is the BuildID that is set to  CFBundleVersion
The most recent Build number as shown below is replaced and set to CFBundleVersion.

After downloading from App center, iOS should show the latest build number as shown in below screenshot.
