Interest rates and currency values interest, relative, currency, correct, strength

Palantir

On page 104, Volume 3(Economics), the relative strength approch to predicting currency values says that if a country has high interest rates, the currency will appreciate. But according to Interest rate parity, the currency should depreciate. Which is correct? Thank you.

The country with the higher real rate will appreciate.
I believe Interest Rate Parity assumes that real rates are equal and nominal rates are different.
