System Compatibility

For the HealthRhythms SDK for iOS, we generally support n-2 versions of Apple’s iOS operating system.

HealthRhythms SDK for iOS Version	Required Xcode Version	Supported iOS Versions
HealthRhythms SDK 1.5.0	Xcode 14.0.1 (SDK 16)	iOS 13, 14, 15 (16*)
HealthRhythms SDK 1.3.0 to 1.4.7	Xcode 13.4.1 (SDK 15)	iOS 13, 14, 15 (16*)
HealthRhythms SDK 1.2.9 and earlier	Xcode 13.4.1 (SDK 15)	iOS 12, 13, 14, 15

(*) Preliminary support only

As of June 2022, more than 99 percent of all iPhone active devices can use your app if your app supports iOS 14 upward. See Apple’s official device statistics for details.

It’s not possible for your app to support an older version of iOS that isn’t supported by HealthRhythms and then only link with HealthRhythms when running on newer iOS versions.

Xcode Support

As of April 2022, Apple requires that all apps submitted to the App Store be built with Xcode 13 and the iOS 15 SDK or later.

In general, the most recent build will always require the most recent stable version of Xcode so that we can utilize all the improvements Apple is making on its tools and compiler infrastructure.
