问题
I am trying to update a Xamarin.iOS binding which points to code that I manage, and I'm having trouble now that I've replaced an external .a library reference with a .framework. Particularly, when I try to compile my binding, native linking is failing for the library which I replaced.
Native linking error: framework not found SVGKit for architecture arm64/i386/armv7/armv7s (MT5209)
I know for a fact that SVGKit supports these architectures, but I'm unsure how to include them in the generated binary when referencing from a .framework.

Hello I would do this to diagnose the issue
First I would check if SVGKit.framework/SVGKitis a fake framework (static library disguised as a framework) or a dynamic one (iOS 8+ support only) using the file command on the binary
file Foo.framework/Foo
Foo.framework/Foo: Mach-O universal binary with 4 architectures
Foo.framework/Foo (for architecture i386): Mach-O dynamically linked shared library i386
Foo.framework/Foo (for architecture x86_64):Mach-O 64-bit dynamically linked shared library x86_64
Foo.framework/Foo (for architecture armv7): Mach-O dynamically linked shared library arm
Foo.framework/Foo (for architecture arm64): Mach-O 64-bit dynamically linked shared library
file Bar.framework/Bar
Bar.framework/Bar: Mach-O universal binary with 4 architectures
Bar.framework/Bar (for architecture armv7): current ar archive random library
Bar.framework/Bar (for architecture i386): current ar archive random library
Bar.framework/Bar (for architecture x86_64):current ar archive random library
Bar.framework/Bar (for architecture arm64): current ar archive random library
Foo is a dynamic library, notice the Mach-O and Bar is a static library disguised as a framework notice the ar
Now if it is a fake framework (static library) just take the SVGKit.framework/SVGKit binary and rename it to SVGKit.a and add it to your binding project, it should work as usual
If it is a Dynamic Framework then follow these instructions on how to do it.[0]
