The Nordic countries of Denmark, Finland, Norway, Iceland and Sweden have an agreement through which citizens of one Nordic country have the right to live in the other countries in the Nordic region.
As a Nordic citizen, you do not need to apply for a permit to move to Sweden.
If you are going to live in Sweden for at least one year, you should get listed in the Swedish Population Register
If you plan to live in Sweden for at least one year, you must report your move to Sweden and get listed in the Swedish Population Register. It is the Swedish Tax Agency that decides whether you meet the conditions for being listed in the Swedish Population Register. Being listed in the Swedish Population Register means that you are registered as a resident of Sweden. Once you are listed in the Swedish Population Register, you will receive a personal identity number.

A Nordic citizen can also be considered an EU/EEA citizen
As a Nordic citizen, you can also be considered an EU/EEA citizen. Through the EU/EEA cooperation, you have the right to live in an EU/EEA country other than your country of origin, if you meet the requirements for right of residence by working, running your own business, studying, or having sufficient funds to support yourself. Read more about right of residence on the page EU/EEA citizens.
If your family will also be living in Sweden
If your family will be living with you in Sweden, and they are not themselves Nordic citizens, they need to apply for a residence card or residence permit. Read more on the page You want to apply – Family of Nordic citizens
