These guidelines build on top of Github Objective-C Code Guidelines, the following guidelines are all Mandantory, you can follow Github's guideline if it is not contray to iCHEF guidelines.

Code Naming

• All iCHEF POS class uses iC

	iCSocketContainer *socket = [iCSocketContainer createSocket];

• No Abbreviations for noun, verb, or adjective in class, method, or any variable names.

	NSDictionary *testDictionary;
	NSMutableDictionary *testDictionary;
	NSArray *testArray;
	NSMutableArray *testArray;
	NSSet *testSet;
	NSMutableSet *testSet;
	
	- (void) getRestaurantDataWithUUID:(NSString *) UUIDString;
	

• All boolean Variables start with is prefix.

	BOOL isEdited;

• All String variables ends with String suffix.

	NSString *testString;

• All String variables can be converted to JSON ends with JSONString suffix.

	NSString *testJSONString = @"{"test":"test"}";
	[testJSONString toJSON];

Documentation and Organization

• All method declarations should be documented.
• All public method should use VVDocumenter to declare design intention, return type, and parameters in the header file.
• All method declareations should have not null or nullable.

   - (nullable returnType *)itemWithName:(nonnull NSString *)parameter; 

• All non-null property should be specified. Otherwise, nullable is the default.

  @property (copy, nonnull) NSArray *allItems;

• Use #pragma mark - to categorize methods into functional groupings and protocol implementations, following this general structure:

#pragma mark - Lifecycle

	+ (instancetype)objectWithThing:(id)thing {}
	- (instancetype)init {}
	- (void)viewDidLoad {}
	- (void)dealloc{}

#pragma mark - Other methods

	- (void)drawRect:(CGRect) {}

• If a method call is too long, press Enter in the header of method segment, just let Xcode to align vertically with :
• All publlic methods or properties should be placed in .h files, all private methods or properties shoud be in .m files.

Import Policy

• Only import what you need in header file , reduce the duty of pch file.

Object Literals

• All NSNumber, NSDictionary, and NSArray must use Object Literals.

	NSNumber *orderCount = @(1 + 2);

 	NSDictionary *testDict = @{obj1, obj2, obj3};

 	NSArray *orderArray = @[obj1, obj2, obj3];

Control Structures

• Use ternary operators to help value assignment.
• Long form ternary operators should be wrapped in parentheses and only used for assignment and arguments.

	Blah *a = (stuff == thing ? foo : bar);

• Short form, nil coalescing ternary operators should avoid parentheses.

	Blah *b = thingThatCouldBeNil ?: defaultValue;

• Comparisons should be explicit for everything except BOOLs.

	if (isEdited) {
		// Bool comparison
 	}

 	if (count >= 3) {
 		//number comparison
 	}

 	if (object == nil) {
 		//null comparison
 	}

Categories

• Categories should be named for the sort of functionality they provide. Don't create umbrella categories.
