I am quite new to Swift and would love to know how to create a loop that runs some code every 30 seconds? I feel as though it is a basic question but I can't really find what I'm looking for.

func startTimer() {
timer = Timer.scheduledTimer(timeInterval: 30, target: self, selector: #selector(UpdateTimer), userInfo: nil, repeats: true)
}
@objc func UpdateTimer() {
counter += 1
}
to start
startTimer();
and to stop
timer.invalidate()

You can make Use of Timer
Timer.scheduledTimerWithTimeInterval(0.30, target: self, selector: #selector(timerFired), userInfo: userInfo, repeats: true)
timerFired: is the method that gets called after interval
@objc func timerFired() {
print("Timer Called with interval 30seconds")
}

You need to use scheduled timer. In viewDidLoad()
Timer.scheduledTimer(timeInterval: 30, target: self, selector: #selector(YourFuncName), userInfo: nil, repeats: true)
and func for selector
@objc func YourFuncName() {
print("every 30seconds")
}
