Error:-
Thread 1: "Unable to activate constraint with anchors <NSLayoutXAxisAnchor:0x280af8500 \"UILabel:0x103dc4fa0.centerX\"> and <NSLayoutXAxisAnchor:0x280af89c0 \"UIView:0x103dc49d0.centerX\"> because they have no common ancestor. Does the constraint or its anchors reference items in different view hierarchies? That's illegal."
I've created a function programmatical in Base view controller which returns a view & I've added some constraints to its
Function:-
func getMarker (lbl:String, img:UIImage) -> UIView {
let myView = UIView(frame: CGRect.zero)
myView.center = CGPoint(x: 50, y: 160)
myView.backgroundColor = UIColor.clear
let imageView = UIImageView(image: img)
imageView.frame = CGRect(x: 0, y: 0, width: 20, height: 40)
myView.addSubview(imageView)
let label = UILabel(frame: CGRect(x: 0, y: 45, width: 120, height: 30))
label.text = lbl
label.textAlignment = .center
label.adjustsFontSizeToFitWidth = true
label.textColor = UIColor.black
label.backgroundColor = UIColor.white
label.layer.borderColor = UIColor.lightGray.cgColor
label.layer.borderWidth = 0.5
label.layer.cornerRadius = 5
label.layer.masksToBounds = true
label.sizeToFit()
NSLayoutConstraint.activate([
label.centerXAnchor.constraint(equalTo: myView.centerXAnchor),
imageView.centerXAnchor.constraint(equalTo: myView.centerXAnchor)
])
myView.addSubview(label)
return myView
}
calling function in another controller but it crashing and showing me the error which I mentioned above
Calling function:-
getMarker(lbl: device.name ?? "", img: (UIImage(named: icfile) ?? UIImage(named: "truck_1_orange")!))
I'm trying to add some text under marker like in the picture mentioned below,I'm using google maps, Swift
I want to add some text under my marker. There is a way to do that?
My Code
self.mapView.clear();
var bounds = GMSCoordinateBounds();
if let lat = alert?.latitude, let lon = alert?.longitude{
let position = CLLocationCoordinate2D(latitude: lat, longitude: lon)
let marker = GMSMarker(position: position);
marker.title = alert?.deviceName;
marker.groundAnchor = CGPoint(x: 0.5, y: 0.5);
marker.map = mapView;
bounds = bounds.includingCoordinate(position);
}
let update = GMSCameraUpdate.fit(bounds)
self.mapView.animate(with: update);
My app worked fine before adding the check notification allow function. and when i add that function, I got this weird crash that gave an error of 'Modifications to layout engine must not be performed from a background thread after it has been accessed from the main thread'. The code that pops up in debugging is this. Any thoughts?

I just started a new project on Xcode 12 with Apple M1 Chip. I did run into issues when I was installing the pods but I was able to fix them using sudo arch -x86_64 gem install ffi then arch -x86_64 pod install. Now, the issue that I am facing is when I added the Alamofire pod for Api Networking. I got an error that said Cannot find type 'apirequests', 'RequestType' in scope and Cannot find type 'ServiceStatusCode' in scope.
