タイプ 'CGPoint！'の値を変換できません。予想される引数の型に 'UnsafeMutablePointer <CGPoint>'

Question

私は迅速なビルドエラーを取得しています。

func pathRefFromText() -> CGPathRef { 

     let attributed : NSAttributedString = self.attrubutedText 
     let line : CTLineRef = CTLineCreateWithAttributedString(attributed as! CFAttributedStringRef) 
     let runArray : CFArrayRef = CTLineGetGlyphRuns(line) 
     for var runIndex = 0; runIndex < CFArrayGetCount(runArray); runIndex++ { 
      let run: CTRunRef = (CFArrayGetValueAtIndex(runArray, runIndex) as! CTRunRef) 
      // let runFont : CTFontRef = CFDictionaryGetValue(CTRunGetAttributes(run), kCTFontAttributeName) 
      for(var runGlyphIndex = 0; runGlyphIndex < CTRunGetGlyphCount(run); runGlyphIndex++) 
      { 
       let thisGlyphRange : CFRange = CFRangeMake(runGlyphIndex, 1) 
       let glyph : CGGlyph! 
       let position : CGPoint! 

       // The build error comes in these two lines 
       CTRunGetGlyphs(run, thisGlyphRange, glyph) 
       CTRunGetPositions(run, thisGlyphRange, position) 

      } 
     } 
    } 

「CGPoint！」タイプの値を変換できませんというビルドエラーが発生しました。期待される引数の型 'UnsafeMutablePointer'

を使用してみてくださいに：CGGlyph：

var glyph : CGGlyph = CGGlyph() 
var position : CGPoint = CGPoint() 

CTRunGetGlyphs(run, thisGlyphRange, &glyph) 
CTRunGetPositions(run, thisGlyphRange, &position)
