I tried making an array of functions and Xcode did not let me. This is the error I get:
Value of type '(ViewController) -> () -> (ViewController)' has no member 'firstFunc'
Essentially I need to know how array of functions are made in order to randomly call them later.
let randomFunc = [self.firstFunc(),self.secondFunc(),self.thirdFunc()]
func firstFunc(){
}
func secondFunc(){
}
func thirdFunc(){
}
I think you need to only give the name of the function, currently you are calling the functions,
And if you want to use self as well you can do something like this: (you need to make this property lazy var to use self)
class foo {
lazy var randomFunc = [self.firstFunc,self.secondFunc,self.thirdFunc]
func firstFunc(){
print(123)
}
func secondFunc(){
}
func thirdFunc(){
}
}
Usage:
let f = foo()
f.randomFunc[0]() // prints 123
lazy var array = [self.fun1,self.fun2,self.fun3]
Functions:
func fun1() {
print("func1")
}
func fun2() {
print("func2")
}
func fun3() {
print("func3")
}
Usage:
self.array[0]()
Prints:
func1
