    public TextMesh loading;

It seems the compiler is not compiling a generics type method. Cannot say much more from the code snippet above.

The Mono .NET implementation for iOS is based on AOT (ahead of time compilation to native code) technology, which has its limitations. It compiles only those generic type methods (where a value type is used as a generic parameter) which are explicitly used by other code. When such methods are used only via reflection or from native code (ie, the serialization system) then they get skipped during AOT compilation. The AOT compiler can be hinted to include code by adding a dummy method somewhere in the script code. This can refer to the missing methods and so get them compiled ahead of time.

void _unusedMethod()
{
    var tmp = new SomeType<SomeValueType>();
}
