Xamarin.Forms Additional Arguments

Question

Hello,

When building an application with Xamarin.Forms, I am running into an error with using the option of Additional Arguments for iOS with -gcc_flags "-fobjc-arc". When I use this argument I get the error of:

Error MT5201: Native linking failed. Please review the build log and the user flags provided to gcc: -fobjc-arc -Xlinker -sectcreate -Xlinker __TEXT -Xlinker __entitlements -Xlinker Documents/GitHub/Trunk/Source/iOS/obj/iPhoneSimulator/Debug/Entitlements.xcent (MT5201) (DOMA.iOS)

When I remove the Additional Argument for iOS, the application can build. Is the argument that I am using incorrect?

Answer 1

Hello,

The -fobjc-arc flag indicates automatic reference counting, which is a memory managing mechanism in the swift language.

Please refer to Automatic Reference Counting for more details.

In C#, since C# has its own memory managing mechanism Automatic Memory Management, you don't need to specify ARC.

Best Regards,

Alec Liu.
