I want disable or remove some initialization from my super class, here my test codes:

class MyA {
    
    init() {
        
    }
    
    init(value: String) {
        
    }
    
    init(value2: String) {
        
    }
}


class MyB: MyA {
    
}

As you can see MyA has 3 initialization and MyB has the same because it is sub class, so I want remove 2 of this 3 initialization in MyB class, I want MyB just be initialize with init(), how can i do this? and the other 2 way be unavailable for sub class.

https://docs.swift.org/swift-book/LanguageGuide/Initialization.html

If your subclass doesn’t define any designated initializers, it automatically inherits all of its superclass designated initializers.

As such, define a designated initializer.

class MyB: MyA {
  override init() {
    super.init()
  }
}
