FWIW here are the restrictions and they do not include IOS.
Samsung Health Android SDK requires Samsung Health installation.
The latest SDK works with Samsung Health 6.12 or above.
See the SDK and Samsung Health’s compatible versions here.
Samsung Health runs on devices with Android 8.0 Oreo (API level 26) or above.
An app’s targetSdkVersion that uses Samsung Health SDK for Android should be 26 or above.
Samsung Health is available on all Samsung smartphones and also non-Samsung Android smartphones with Marshmallow or above.The SDK provides APIs to check whether the device supports the SDK. See FAQ for more information.
You also need to create the support request and ask for it that way. I don’t have any answers for the Health Partners other than Developer Partners. The health team is pretty good about responding via that channel.
