Yesterday, Apple unloaded several tips to developers working on applications for the Mac App Store, due sometime next month. Among these articles are requirements that apps “must write files in the appropriate location” to keep users from being confused if they see a folder or data that is somewhere it shouldn’t be. For example, Apple states that any database files must be stored in the user’s Library folder, and be easily identifiable as being tied to a certain application.
Apple also urged developers to follow the Apple Human Interface Guidelines documents when creating their apps, especially if they need to make use of any custom-built controls. Like the iOS SDK, the Mac SDK includes countless controls and interface examples that developers can use when working with their apps. Clearly, Apple wants to help maintain a consistent feel across apps.
With the Mac App Store launch coming soon, expect to see more from both Apple and developers about the new platform.
