Open HealthKit App from another app

Question

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?

Answer 1

iOS does not provide a general API for launching other applications and the Health app would need to have support for URL scheme in order for you to launch it from your own application. See Launch an app from within another (iPhone).

Answer 2

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://")!)

See Open Health app using url scheme | Apple Developer Forums.

Answer 3

Swift 5 "Safer way"

func openUrl(urlString: String) {
    guard let url = URL(string: urlString) else {
        return
    }

    if UIApplication.shared.canOpenURL(url) {
        UIApplication.shared.open(url, options: [:], completionHandler: nil)
    }
}

Usage:

openUrl(urlString: "x-apple-health://")
