Thanks, this works. Only the archivers really don't like a vector with
no elements, so as a workaround I first tried to use conditionals: if
(size > 0)
but that gives another error when reading back in: "byte expected".
So I now always keep one element in the vector array. It's a bit
annoying.

You can encode it just like you would a plain C array:
//Encode
const unsigned size = myVector.size();
[aCoder encodeValueOfObjCType: @encode(unsigned) at: &size];
[aCoder encodeArrayOfObjCType: @encode(unsigned) count: size at:
&myVector.front()];
//Decode
unsigned size;
[aCoder decodeValueOfObjCType: @encode(unsigned) at: &size];
myVector.resize(size);
[aCoder decodeArrayOfObjCType: @encode(unsigned) count: size at:
&myVector.front()];
