kandi X-RAY | Ackbar Summary
Swift's type system ensures that your methods are interacting with objects of the correct type, but you are left to using conditionals and assertions to validate their values. You can test conditionals, but until now you were not able to test Swift's assertions (assert, precondition, fatalError) without crashing your test run. Ackbar allows you to write unit tests which verify that your assertions have test coverage and fire when you expect them to.

to be a more robust and flexible alternative.
The mix-blend-mode
property allows you to control the blending behavior of an element against it's background. In your case, the contrasted appearance can be achieved via the "difference" blend mode to ensure the burger bars are visible in most cases.
The difference blend mode can be thought of as "color inversion" - when applied to your burger menu, this would ensure that the menu is visible under most backgrounds. The other nice thing about this approach is that it will work against most solid color, image or gradient backgrounds.
You can make use of blending for your menu by adding the following CSS:

I want to read a JSON array from a file and want to pass it to pymongo to write multiple documents into a collection.
I have already tried to read the file as normal text with file.read() but the pymongo.insert_many() expect a list and not a string, so I though I have to parse it as JSON, but it drops an error.
