Google Maps Swift Camera Rotate 360 Smooth

google-swift-camera-360.swift

    var timer:Timer!
    var degree = 0
    @objc func rotate() {
        // assumes google map called 'map'
        self.map.animate(toBearing: CLLocationDirection(degree))
        if degree == 360 {
            timer.invalidate() // comment out this line for continual rotation
            degree = 0
        }
        degree += 18
    }

    func startRotation() {
        timer = Timer.scheduledTimer(timeInterval: 0.18, target: self, selector: #selector(rotate), userInfo: nil, repeats: true)
    }

Wrote this for a screen capture where I wanted to rotate around a marker and then loop the video and export in to a gif.
