Listing all `dynamic` variables for a class in Swift2

fixed the issue. Will look into that further I'm writing a base class that implements KVO, and I would like to infer the names of the dynamic attributes of the class. For example: , You can use the standard functions:
class MyObject {
    dynamic var identifier = 0

    func dynamicProperties() -> [String] {
        var dynamicProperties = [String]()

        var propertyCount = UInt32(0)
        let properties = class_copyPropertyList(object_getClass(self), &propertyCount)
        for var i = 0; i < Int(propertyCount); i++ {
            let property = properties[i]
            let propertyName = property_getName(property)
            dynamicProperties.append(String(CString: propertyName, encoding: NSUTF8StringEncoding)!)
        }
        free(properties)

        return dynamicProperties
    }
}
class BaseClass {
    dynamic var identifier = 0

    func dynamicProperties() -> [String] {
        var dynamicProperties = [String]()

        var propertyCount = UInt32(0)
        let properties = class_copyPropertyList(object_getClass(self), &propertyCount)
        for var i = 0; i < Int(propertyCount); i++ {
            let property = properties[i]
            let propertyName = property_getName(property)
            dynamicProperties.append(String(CString: propertyName, encoding: NSUTF8StringEncoding)!)
        }
        free(properties)

        return dynamicProperties
    }
}

class SubClass : BaseClass {
    dynamic var name: String!

    override func dynamicProperties() -> [String] {
        var dynamicProperties = super.dynamicProperties()

        var propertyCount = UInt32(0)
        let properties = class_copyPropertyList(object_getClass(self), &propertyCount)
        for var i = 0; i < Int(propertyCount); i++ {
            let property = properties[i]
            let propertyName = property_getName(property)
            dynamicProperties.append(String(CString: propertyName, encoding: NSUTF8StringEncoding)!)
        }
        free(properties)

        return dynamicProperties
    }

}

NSClassFromString not totally dynamic - Swift2


Tag : xcode , By : Milander

I hope this helps you . Based on your code I assume you want dynamically choose a class, and then call known methods. For that you will need to define a protocol first. For example:
protocol MyProtocol: class {
    init()
    var lessonID: String { get set }
    func test()
}
let className = "MyModule.MyClass" // this is how swift class names look like

if let classType = NSClassFromString(className) as? MyProtocol.Type {
    // call methods from your class, but only those specified in the protocol:
    let object = classType.init()
    object.lessonID = "15"
    object.test()
}

In swift2, is it possible to assign a tuple with 2 elements to 2 variables where one is a constant and one can be mutate

it should still fix some issue In the following example, the xcode compiler has a warning on the first line: Variable 'y' was never mutated, consider changing to let constant. , You can do this with Swift pattern matching:
while case (var x, let y)? = stack.tryPop() {
    // .. x is mutated
    x++

    // y is not mutated
}
