@NguyenVanLieu0405,

can you try again with HERE SDK 4.24.5.0 or newer? And Xcode 26.2. It should run fine with iOS 26.2. We used iPhone 17 Pro.

If you can still repro, please provide the full logs and which app you executed. Thank you!

@HERE-SDK-Support-Team
I have tried with the latest version of HERE SDK(4.25.0.0), Xcode 26.2, and ran it on iOS 26.2, but the same error still occurs.

Please check for me.
Thank you so much!

Dear @HERE-SDK-Support-Team
Please check it for me and let me know as soon as possible.
Thank you!

@NguyenVanLieu0405, thanks for getting back. This configuration is supported and should work.

The error "Undefined symbol: protocol conformance descriptor for Swift.String : Swift.Error in heresdk
Linker command failed with exit code 1" may be caused by a local problem. Probably due to local stale build artifacts.

Try to clean your Xcode cache and please describe the precise steps you did to get this error (what app, HSDK integration steps, build steps).

Please also send the full linker error (with all undefined symbols, not just the String/Error one).

Check also "Build Settings → Always Embed Swift Standard Libraries = YES."

Thank you!
