快速坐标系视图

Question

I recently checked out the Swift Playgrounds App available inside the App Store where I stumbled across this interactive coordinate system view similar to the one that can be found inside of Xcode playgrounds on the Mac.

My question is if this framework is accessible for developers or if it's something Apple developed internally for the playground?

Thanks in advance.

Answer 1

It seems like apple is using it internally. But you can build it yourself see this blogpost for inspiration. However it's written in Swift 3 but it should be easily transferable to Swift 4.
