The code in the test app is this:

FWIW, 102 is 0x66, or a lower case “f”. Also, I think a “$” at the start of an archive key is an escape character, and so probably shouldn’t be taken literally. However, I don’t know what key you’d need to ask for instead.

On to the code…

The first few times I tried this, I thought I got inconsistent results, but maybe I just did something wrong. The last several times I tried, I got the same exception as you, but only with the “float” type. All the other types I tried worked.

One odd thing I noted. If I encoded the array as anything other than float elements (e.g. specifying “@encode(double)” or “@encode(short)”), and decoded with “@encode(float)”, I got this exception message:

*** -[_NSKeyedCoderOldStyleArray decodeArrayOfObjCType:count:at:]: type ('f') or count (6) does not match stored type and count ('d', 6)

but if I encoded the array as “@encode(float)” and decoded it as anything else, I got this exception message:

*** -[_NSKeyedCoderOldStyleArray initWithCoder:]: unable to decode element in array of size (4) and count (6)

It’s very odd.
