@viirak, not sure what your problem is, the information you are providing not very helpful.

According to Apple's documentation the speedAccuracy property is available since iOS 10.0+ (hence the if statement). I have tested the plugin on several versions of iOS and all seem to work. Also code compiles fine. Can you provide more information?

I have the same bug after updating lib:

geolocator: ^6.1.4 geocoding: ^1.0.5

Flutter version:

Channel stable, 1.22.3

and the problem is:

`Running Xcode build...
Xcode build done. 24,5s

I installed the latest package i.e geolocator: ^6.1.4.
I was able to use it to get my current position on the android device but once I ran the iOS simulator, I got the following error:

I am a bit puzzled here, can I ask which version of Xcode do you have installed?

[retuner87]

My xcode version is Version 11.3.1 (11C504)

[mvanbeusekom]

I am on "Version 12.1 (12A7403)", I will try downgrading and see if that is the problem.

[mvanbeusekom]

I can confirm that this issue is related to the version of Xcode. I have installed version 11.3.1 and also now receive this issue. When compiling on Xcode version 12.1 this issue does not occur.

I will try to figure out if there is a workaround for this, please bare with me. For now possible workarounds are:

• downgrade to version 6.1.3 of the geolocator plugin
• or upgrade your Xcode to version 12.1

[mvanbeusekom]

@viirak, @retuner87, @GwamakaCharles, I have just released a hotfix (version 6.1.4+1) of the geolocator plugin which should fix this issue. Simply run a flutter pug update command (or update the version of the geolocator in your pubspec.yaml) to use this version.

Thank you for reporting.

Thanks @mvanbeusekom for your support!
