This can still be done if we so choose (using either Apple's fast, low-level API, Metal, or OpenGL), but over time, the process of visually creating and editing particle effects has gotten easier. Not too long ago in the iOS development history, frameworks such as Cocos2D/ Cocos3D allowed us to use third-party particle effects builders to import into our games. With both SpriteKit and SceneKit, Xcode...
