Explain the working or purpose of synthesize

---

Basically, @synthesize automatically generates the getters and setters based on the @property declaration.

---

synthesize used with property.When you declair a property in .h file then you need to synthesize that in .m file.

@synthesize creates getter and setter for your property.If you do not synthesize the property then you can use property.(it gives crash).

var=self.yourProperty (calling getter). simmiler to var=[self getYourProperty];

self.yourProperty=var (calling setter). simmiler to [self setYourProperty:var];

without synthesize you cant use the setter and getter.
