[health 13.1.4] App crashes on launch with DYLD Symbol missing on iOS 16

[anies1212]

Plugin Name

health

Plugin Version

13.1.4

Device

iPhone 8 (iPhone10,1)

Operating System

iOS version: 16.0.2

Describe the bug

Description

App crashes immediately on launch on iOS 16 devices. The crash occurs before any Flutter code executes.

This started happening after upgrading from health 11.1.1 to 13.1.4.

Workaround

Downgrade to health: ^11.1.1

Additional Context

This issue appears to have been introduced in health 13.0.0 with the Swift native code refactoring (PR #1208). The HKElectrocardiogramQuery Swift extension seems to require iOS 17+.

Please consider either:

1. Updating the podspec to reflect the actual minimum iOS version requirement
2. Adding @available checks to maintain iOS 16 compatibility

Steps to Reproduce

1. Create a new Flutter project
2. Add health: ^13.1.4 to pubspec.yaml
3. Run flutter pub get
4. Add HealthKit capability and required Info.plist entries
5. Build and run the app on an iOS 16 device (or simulator)
6. App crashes immediately on launch before any code executes

Expected Behavior

App should launch on iOS 16 devices, as the podspec states s.ios.deployment_target = '14.0'.

Actual Behavior

App crashes at launch due to missing Swift symbol (HKElectrocardiogramQuery.Result.measurement) in iOS 16's HealthKit framework.

We're experiencing the same crash on our production app.

Affected iOS versions:

• iOS 16.7.12
• iOS 15.8.5

This confirms the issue affects not only iOS 16.0.x but also iOS 15.x devices.

Downgrading to health: ^11.1.1 works as a workaround for now.
