I want to build a fitness app that will upload the data to HealthKit. Is there any way to open/navigate to HealthKit from another app?
On iOS 10, the Health app URL scheme is x-apple-health
. You can open it from within your own app by calling:
Objective-C:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"x-apple-health://"]];
Swift:
UIApplication.shared.open(URL(string: "x-apple-health://")!)
