swift - how to filter out/exclude some indexes from a CGPoint array -

i have array of cgpoints (spritepositions) , create skspritenode's selected number of positions (leaving specific indexes of out). please see code below:

createsprite(missingindexes: [int])    {      //for (index, value) in enumerate(spritepositions)  filtering out/excluding missingindexes array {          var sprite = skspritenode(imagenamed: "spriteimage")          sprite.position = value          addchild(sprite)      } } 

you can use contains function on missingindexes array filter out indices. if index not contained in missingindexes process normal. if index containted in missingindexes, nothing.

swift 1.2:

for (index, value) in enumerate(spritepositions) {     if !contains(missingindexes, index) {         var sprite = skspritenode(imagenamed: "spriteimage")         sprite.position = value         addchild(sprite)     } } 

swift 2.0

for (index, value) in spritepositions.enumerate() {     if !missingindexes.contains(index) {         var sprite = skspritenode(imagenamed: "spriteimage")         sprite.position = value         addchild(sprite)     } }
