Sign in with Apple could give Facebook and Google some serious headaches when it launches as part of iOS 13 this fall, however, Apple’s strict rules could bring some pushback.
Not only will Apple require all apps that use third-party login services like Facebook to also support Apple’s privacy-focused login service, but it is also asking that the button be placed above competitors’ options.
Apple updated its Human Interface Guidelines this week outlining the new rules that come with iOS 13. The guidelines suggest that developers shouldn’t prompt for a sign-in until they absolutely need to. When they do ask for sign ins, Apple wants top billing
“Position a Sign In with Apple button correctly in relation to other sign-in buttons. In a stacked layout, place the Sign In with Apple button above the other buttons,” Apple suggests, (emphasis ours).
Usually Apple is all about keeping things consistent. When it comes to the Sign in with Apple button though, the company is totally fine with it being bigger than other sign-in buttons.
“Make a Sign In with Apple button the same size or larger than other sign-in buttons, and avoid making people scroll to see the button,” the guidelines state.
Developers don’t have to follow the guidelines to a tee, but an app that breaks them is less likely to gain App Store approval. Sign in with Apple will be available on macOS, tvOS, watchOS, iOS and the web this fall.
