During an instance initialization, the initializer blocks are executed in the same order as they appear in the class body, interleaved with the property initializers:

First, default constructor arguments are evaluated, starting with argument to the constructor you call directly, followed by arguments to any delegated constructors. Next, initializers (property initializers and init blocks) are executed in the order that they are defined in the class, top-to-bottom. Finally, constructors are executed, starting with the primary constructor and moving outward through delegated constructors until the constructor that you called is executed. The constructor order is probably the most surprising, since no matter where in the class the constructor is defined, it is always executed after all initializers have run.
