Issue Description:

$ cat Circle.swift
class Circle {
    var radius: Int
}

$ swiftc Circle.swift
Circle.swift:1:7: error: class 'Circle' has no initializers
class Circle {
      ^
Circle.swift:2:9: note: stored property 'radius' without initial value prevents synthesized initializers
    var radius: Int
        ^
                    = 0

Note that the error refers to "synthesized initializers" The canonical swift book refers to these as "Default Initializers"

Either the book or the compiler error message should be changed to consistently call these the same thing.

研究方向
Investigate the Swift compiler source code to locate the error message containing 'synthesized initializers'. The string is likely in the Sema (semantic analysis) component. Also review Apple's official documentation for 'Default Initializers'. The issue does not specify which to change, so decide whether to update the compiler or the documentation, and ensure consistency.
