Flat design became a thing and we saw an overnight shift in design approach for interfaces when Apple introduced iOS 7 in 2013. They certainly took elements that other manufacturers were already implementing but the impact Apple has on the rest of the industry (as a trend-setter) cannot be matched.

iOS 7 saw a massive jump in design language for iOS. Apple introduced a much simpler and flatter design compared to its predecessor’s more complex and skeuomorphic design. Tim Cook called it “the biggest change to iOS since iPhone.”

I remember when that shift happened. I installed an early beta of iOS 7 and was blown away by the change. Now, slowly, icons and logos are bringing back some life and color. I love it. Recommend checking out the article, has some great examples.
