Did you knew that Clang Analyzer as alpha checkers? Early Christmas is here! (Ignore the rest... we run our PDF SDK with -Weverything because warnings are awesome to prevent bugs) - See for a list of Xcode 8.3 changes
// clang -cc1 -analyzer-checker-help
// OVERVIEW: Clang Static Analyzer Checkers List
// USAGE: -analyzer-checker <CHECKER or PACKAGE,...>
// alpha.core.BoolAssignment Warn about assigning non-{0,1} values to Boolean variables
// alpha.core.CallAndMessageUnInitRefArg
// Check for logical errors for function calls and Objective-C message expressions (e.g., uninitialized arguments, null function pointers, and pointer to undefined variables)
// alpha.core.CastSize Check when casting a malloc'ed type T, whether the size is a multiple of the size of T
// alpha.core.CastToStruct Check for cast from non-struct pointer to struct pointer
// alpha.core.DynamicTypeChecker Check for cases where the dynamic and the static type of an object are unrelated.
// alpha.core.FixedAddr Check for assignment of a fixed address to a pointer
// alpha.core.IdenticalExpr Warn about unintended use of identical expressions in operators
// alpha.core.PointerArithm Check for pointer arithmetic on locations other than array elements
// alpha.core.PointerSub Check for pointer subtractions on two pointers pointing to different memory chunks
// alpha.core.SizeofPtr Warn about unintended use of sizeof() on pointer expressions
// alpha.core.TestAfterDivZero Check for division by variable that is later compared against 0. Either the comparison is useless or there is division by zero.
// alpha.cplusplus.VirtualCall Check virtual function calls during construction or destruction
// alpha.deadcode.UnreachableCode Check unreachable code
// alpha.osx.cocoa.DirectIvarAssignment
// Check for direct assignments to instance variables
// alpha.osx.cocoa.DirectIvarAssignmentForAnnotatedFunctions
// Check for direct assignments to instance variables in the methods annotated with objc_no_direct_instance_variable_assignment
// alpha.osx.cocoa.InstanceVariableInvalidation
// Check that the invalidatable instance variables are invalidated in the methods annotated with objc_instance_variable_invalidator
// alpha.osx.cocoa.MissingInvalidationMethod
// Check that the invalidation methods are present in classes that contain invalidatable instance variables
// alpha.osx.cocoa.localizability.PluralMisuseChecker
// Warns against using one vs. many plural pattern in code when generating localized strings.
// Warn about buffer overflows (older checker)
// Warn about buffer overflows (newer checker)
// Check for overflows in the arguments to malloc()
// Check for an out-of-bound pointer being returned to callers
// Generate taint information used by other checkers
