Swift async/await in a for loop or map

Question

I have this model:

struct ExactLocation {
    var coordinates: CLLocationCoordinate2D? {
        get async throws {
            let geocoder = CLGeocoder()
            let placemark = try await geocoder.geocodeAddressString(address)
            let mark = MKPlacemark(placemark: placemark.first!)
            return mark.coordinate
        }
    }
}
struct Property {
    let exactLocation: ExactLocation?
}

I am trying to loop over an array of Property to fetch all the coordinates using Swift 5.5 async/await.

private func addAnnotations(for properties: [Property]) async {
    let exactLocations = try? properties.compactMap { try $0.exactLocation?.coordinates } <-- Error: 'async' property access in a function that does not support concurrency

    let annotations = await properties.compactMap { property -> MKPointAnnotation? in
        if let exactLocation = property.exactLocation {
            if let coordinates = try? await exactLocation.coordinates {
                
            }
        }
    } <-- Error: Cannot pass function of type '(Property) async -> MKPointAnnotation?' to parameter expecting synchronous function type

    properties.forEach({ property in
        if let exactLocation = property.exactLocation {
            if let coordinates = try? await exactLocation.coordinates {
                
            }
        }
    } <-- Error: Cannot pass function of type '(Property) async -> Void' to parameter expecting synchronous function type
}

So how can I iterate over this array with an async function? Do I need to create an AsyncIterator? The docs are quite confusing on this, how would I do this for this simple example?
