[SWIFT] Complete self-study IOS app development diary

From today, completely inexperienced people will self-taught (one reference book) and would like to drop articles up to IOS application development.

• Since the goal is to organize and establish the learning content, I think the update will be a night type.
• In terms of level, Rails can be implemented on the server side.

why

We expect three effects.

1. Increase learning efficiency by being aware of the output. 2, Organize only the main points. 3, Cut off the retreat by declaring!

Let's Go!

Today's learning content.

1, Features of Swift

・ First of all, what kind of language is Swift? → You can develop Mac and Ios applications ...

More details ... It is a statically typed language that determines the value information of variables and constants at the compile-time execution stage. (It is a language whose safety is guaranteed because it displays incorrect information as a compilation error. It seems that it is also suitable for large-scale development.)

2, important words

• From here, we will select the concepts and languages that we feel are particularly important in advancing learning!

Type inference ... Guess the type such as (String) for strings and (Int) for numbers.

Generics ... Declare the type clearly before defining the variable. (Since the type is specifically declared and passed as an argument, there is a lot of description.) ← This.

Library Standard Library-A library that comes standard with Swift.

Core library-Library used for asynchronous, communication, and file operations

・ Foundation A library that provides the functionality needed by many apps

・ Libdispatch A library that performs parallel processing of hardware

Development tools ... LLDB (tools that make it easier to find bugs /binding.pry-like ...)

Naming convention -Variables, functions, constants-Use camelCase.

Tips for choosing words ・ Ambiguous × ・ Abbreviation × ・ General ○ ← That's right.

3, Personal Topic

I have personally felt so far. (Honestly ... the content is light.)

From now on, I will do my best to update it every day! ... It's pretty painful to write it down here.

I really hope that it will help beginners and beginners.
