I can get Swift Playgrounds to crash fairly easily by adding maybe 7-8 playground pages to the same playground project. It's been like this for as long as I can remember. Comments crashing -- that's a new one.
Playgrounds are supremely unreliable and honestly Apple should just shut them down if they're not going to invest in making them more reliable and usable.
Many of the answers here pertain to Cocoapods. If you're using Carthage and seeing this issue, ensure that you're setting any frameworks in your project to "Embed & Sign" in the Project Settings -> <Target name, in Targets section> -> Frameworks, Libraries, and Embedded Content section.
