Error when unlocking lock in maui

[uengmim]

Hello, I'm using TTLock in maui. I converted the Objective-C code to C# for developing the ios code, but the following error occurs.
Objective-C exception thrown. Narne: NSInvalidArgumentException Reason: [NSInlineData AES256DecryptWithKey:glv:]: unrecognized selector sent to instance Ox117 15800 Native stack trace 0 CoreFoundation Ox0000000180fb7070 6174789A-E88C-3F5C- BA39-DE2E9EDC0750+626800 1 libobjc.A.dylib 0x00000001994d1f54 objc_exception_throw + 60 2 CoreFoundation Ox000000018109401c 6174789A-E88C-3F5C- BA39-DE2E9EDC0750+ 1531932 3 CoreFoundation Ox0000000180f4c484 6174789A-E88C-3F5C- BA39-DE2E9EDC0750+ 189572 4 CoreFoundation 0x0000000180f4b5c0_CF_forwarding_prep_0 t 96 5 WorkerScreen 0x0000000100fb7d9c WorkerScreen +195996 6 WorkerScreen 0x000000010f9b3a8 WorkerScreen +78760 7 WorkerScreen Ox0000000100fb869c WorkerScreen +198300 8 WorkerScreen Ox0000000100fb8640 WorkerScreen + 198208 9 WorkerScreen 0x0000000100f8c8c0 WorkerScreen + 18624 10 WorkerScreen 0x0000000100f9dfac WorkerScreen +90028 11 WorkerScreen Ox0000000101016088 xamarin_get_original_working_directory_path +8604 12 WorkerScreen Ox0000000101342818
What kind of error is this?

    /// <summary>
    /// TTLOCK UnLock
    /// </summary>
    /// <param name="device">Lock devide</param>
    /// <param name="LockData">Lock data</param>
    public void DoUnlock(LockDevice device, string LockData)
    {

        TTLock.ControlLockWithControlAction(TTControlAction.TTControlActionUnlock, LockData, ControlActionSucceedBlock, ControlActionFailedBlock);
    }
    
    C# is using it like this.

Reason: [NSInlineData AES256DecryptWithKey:glv:] ... Because it is missing -ObjC.
Important! Find Target->Build Settings -> Linking -> Other Linker Flags ,add -ObjC（If it already exists, there is no need to add it.）

이유: [NSInlineData AES256DecryptWithKey:glv:] ... -ObjC가 없기 때문입니다. 중요! 대상 찾기->빌드 설정 -> 연결 -> 다른 링커 플래그, -ObjC 추가(이미 있는 경우 추가할 필요가 없습니다.)

Thank you for your answer.
The same error occurs even though -ObjC has already been added to the Other Linker Flags in XCode.
In that case, do I need to set up something else?
It is being developed by visual studio.

Maybe this position is not checked.

Do I have to use XCode? Can't I just run it with VisualStudio?
This method cannot be added in VisualStudio.

sorry, We do not used Visual Studio before.
