NSInvalidArgument exception when using #selector swift3

Question

When I run the function

func makeSpriteShoot(bullets bulletInfo:MHBulletInformation,player playerSprite:SKSpriteNode){
    print("Foo")
    let shootTimer = Timer.scheduledTimer(timeInterval: bulletInfo.frequency, target: true, selector: #selector(shootBullet), userInfo: nil, repeats: true)
}
func shootBullet(){
    player.shootBullet(angle: 90)//player is a instance of a subclass of SKSpriteNode
}

I get the following exception+SIGABRT:

terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFBoolean shootBullet]: unrecognized selector sent to instance ...

Both of the above functions are inside a subclass of SKScene running in Swift3.

Notably I do not get any compile time error unlike #selector(test)

Answer 1

You have made mistake in setting target with Boolean value.

target is the object to which to send the message specified by aSelector when the timer fires. The timer maintains a strong reference to target until it (the timer) is invalidated.

So simply set target to self if method exist in class where you scheduling Timer.

let shootTimer = Timer.scheduledTimer(timeInterval: bulletInfo.frequency, target: self, selector: #selector(shootBullet), userInfo: nil, repeats: true)
