Hej M&k01,
Yes its in thier policy that you need to apply from the country of the origin. You can check on migrationsverket.se for the requirement that you need to submited online. Your birth certifikat and marriage contact if your married must be authenticated by nso. If you meet all the requirement submit it all att once coz it will be more easier for the Swedish migration board to decide. Normaly it took only few months like max 3 months but its always depend on your case.If you want to know more info don't hesitate to communicate with manila Swedish consulate office...to apply online is the quickies way.
Lycka till
