Learn notes from the zero-starting Swift (day 56)--naming convention

The code is full of its own defined names, and it is important to take a well-qualified name.

There are many naming methods, but the more famous, widely accepted nomenclature is:

• Hungarian naming, generally just named variables, the principle is: variable name = Type prefix + description, such as Bfoo represents a Boolean type variable, Pfoo represents a pointer type variable. Hungarian naming is still controversial, and several of the swift code codes do not use Hungarian nomenclature.
• L hump naming (Camel-case), also known as camel nomenclature, refers to the use of mixed uppercase and lowercase letters to name. The hump name is divided into: small hump method and big hump method.

A) The small hump method is the first word is all lowercase, followed by the first letter of the word capitalization, such as: Myroomcount;

b) The big Hump method is the first word of the initial letter is also capitalized, such as: classroom.

Hump naming is the main naming method of Swift coding specification, the more named content is different, can choose small hump method or big hump method. The following categories illustrate:

• To name classes, structs, enumerations, and protocols, the large hump method, such as Splitviewcontroller, should be used.
• File name, using the big hump method, such as Blockoperation.swift.
• Extension file, sometimes the extension is defined in a separate file, it is named "Original type name + extension" as the extension file name, such as Nsoperation+operations.swift.
• Variables and attributes should be used with small hump methods, such as Studentnumber.
• Constant, using the large hump method, such as Maxstudentnumber.
• Enumeration members, similar to constants, using the large hump method, such as executionfailed.
• Function and method should adopt small hump method, such as Balanceaccount, isbuttonpressed and so on.
