SwiftではCGColorSpaceReleaseなどを手動で呼んではいけない

More than 5 years have passed since last update.

※ちょっと自信ありません。

Objective-CのソースからCoreGraphics系の処理を移植したら、関数を抜けるタイミングで何故かEXC_BAD_ACCESSが発生したのですが、どうやら手動でCGPathReleaseCGColorSpaceReleaseなどを呼んでいた部分が原因のようです。

どういうカラクリかはちょっと判りませんが、SwiftではCF Objectsは勝手にReleaseされるようになったようですね。
CGPathdeinitでreleaseしてるとかそんな感じなのかな?)
