Swift

Sample

• Prefer structs over classes wherever possible
• Default to marking classes as final
• Prefer protocol conformance to class inheritance
• Break long lines after 100 characters
• Use 2 spaces for indentation
• Use let whenever possible to make immutable variables
• Name all parameters in functions and enum cases
• Use trailing closures
• Let the compiler infer the type whenever possible
• Group computed properties below stored properties
• Use a blank line above and below computed properties
• Group methods into specific extensions for each level of access control
• When capitalizing acronyms or initialisms, follow the capitalization of the first letter.
• When using Void in function signatures, prefer () for arguments and Void for return types.
• Prefer strong IBOutlet references.
• Avoid evaluating a weak reference multiple times in the same scope. Strongify first, then use the strong reference.
• Prefer to name IBAction and target/action methods using a verb describing the action it will trigger, instead of the user action (e.g., edit: instead of editTapped:)
