As a designer who grew up on the Mac and Apple’s Human Interface Guidelines, you can bet I believe in sticking—wherever you can—to the guidelines. They still leave room for innovation, and they stop you worrying about the stuff that’s already been worked out.

This is a very basic rule which goes out a long way. Always follow the design guidelines provided by operating system or the device manufacturer. The reason is that these guidelines themselves are based on basic principles of consistency and simplicity. Be it Google’s Material Design, Apple’s Human Interface Guidelines or any other design system defined by the brand or the company, all of them uphold these principles.
