Hi! Here comes another question related to the KMLViewer MapKit example: My KML file contains 11 annotations in the form of MKPointAnnotation. Each of them contain a text, which can be found in '_title', in the Xcode debugger. But it is not displayed on the map (MKMapView). Can any one help me figure out why? Thank you! The KMLViewer can be found here: https://github.com/ooper-shlab/KMLViewer-Swift It can be imported directly in Xcode.

My question yesterday - https://developer.apple.com/forums/thread/680107 - was probably to complex for anyone to want to try to answer, I am sorry! So now I will break it up, and start with a smaller question: I am trying to show 10 simple lines on a map with Map Kit. The lines have been loaded into a list called 'overlays' by a module called KMLviewer, or more exactly KMLparser, inside KMLviewer - from https://github.com/ooper-shlab/KMLViewer-Swift . As you can see from my debugging log below, 'overlays' is a list of elements of the type 'MKOverlay', although in reality they are all MKPolyline(s). So how do I access the 2 geographic points that make up each line? MKPolyline inherits from MKMultiPoint, which has a function: func points() - UnsafeMutablePointerMKMapPoint "Returns an array of map points associated with the shape. " But as you can see from my debugging below, I can't seem to access that function, now that the MKPolyline is "inside" an MKOverlay. So how do I access the points?: (lldb) po overlays ▿ 10 elements     - 0 : MKPolyline: 0x60000368bc60     - 1 : MKPolyline: 0x60000368bcd0     - 2 : MKPolyline: 0x60000368bd40     - 3 : MKPolyline: 0x60000368bdb0     - 4 : MKPolyline: 0x60000368be20     - 5 : MKPolyline: 0x60000368be90     - 6 : MKPolyline: 0x60000368bf00     - 7 : MKPolyline: 0x60000368bf70     - 8 : MKPolyline: 0x600003690000     - 9 : MKPolyline: 0x600003690070 (lldb) po overlays[0] MKPolyline: 0x60000368bc60 (lldb) po overlays[0].coordinate ▿ CLLocationCoordinate2D     - latitude : 64.47726683920816     - longitude : -21.420572185955933 (lldb) po overlays[0].points() error: EXPR:3:13: error: value of type 'MKOverlay' has no member 'points' overlays[0].points() ~~~ ^~ (lldb)

Hi! Years ago Apple created an MKMapView demo called KMLViewer. It includes a KMLParser that reads a KML file and converts the data to Map Kit classes. Originally it was in Obj. C, but someone translated it to Swift, and put it here: https://github.com/ooper-shlab/KMLViewer-Swift I imported it directly into Xcode and made it read a KML file I have created. It correctly finds 10 overlays in the form of MKPolyline and 11 annotations in the form of MKPointAnnotation, but they are not shown/displayed correctly. The biggest problem is that the lines are totally missing. And when I look at the overlays I can't seem to find the 2 geographic points/positions/locations that describes each line. I am not sure how to make Xcode print out the content of the MKPolyline(s) instances in a way I can include here as text, and it seems you can't attach a screenshot here either, but I have managed to put the screenshot here: transformation.dk/deling/screenshot-overlays-MKPolyline-2021-05-13.png So you can see the content as I found it. It seems to correctly indicate that the MKPolyline consists of 2 geographic points, but I haven't been able to find the points themselves... On the annotations I was able to find the point, in the Xcode debugger, in this way: (lldb) po annotations[0].coordinate I hope someone can help me understand what is going on, and how to find the relevant debugging/tracking information in Xcode. I am a bit surprised that I had to specifically write ".coordinate" in "po annotations[0].coordinate" in order to find the geographic point of the annotation! I am aware that the problem might also be the MKPolylineRenderer class or the mapView:rendererForOverlay: method, so I have included the references to those in KMLviewer below: swift override func createOverlayPathRenderer(_ shape: MKShape) - MKOverlayPathRenderer? { let polyLine = MKPolylineRenderer(polyline: shape as! MKPolyline) return polyLine } (EDIT: PS: The following code was display incorrectly in the preview...:) swift func rendererForOverlay(_ overlay: MKOverlay) - MKOverlayRenderer? { // Find the KMLPlacemark object that owns this overlay and get // the view from it. for placemark in _placemarks { if placemark.overlay === overlay { return placemark.overlayPathRenderer } } return nil }

Hi I am an absolute beginner in Swift. A friend helped me setup a test app that displays a map using Map Kit. This is the part that creates the actually map: class KMLViewerViewController: UIViewController, MKMapViewDelegate { let map = MKMapView() // etc. ... } I tried to set mapType to hybridFlyover in different ways, like this for instance: let map = MKMapView(.mapType = .hybridFlyover ) But everything returns an error... Can any one help me, please? Where can I find an explanation of swift syntax?

After filling all fields on the "Test Information" page and saving, I still get the yellow warning: "Complete test information is required to submit a build for external testing." Why?

Following a 2 years old video about Xcode, I created app icons and launch images using fanstudio.co.uk/appicon. I then copied the app icons into this folder: my project / Resources / Images.xcassets / AppIcon-1 And the launch images into this folder: my project / Resources / Images.xcassets / LaunchImage Then I was able to choose the app icons in Xcode: Project Navigator - Targets - General - App Icons Source. But I can't choose the launch images. There is nothing to choose from under "Launch Screen File:", and the "Launch Images Source:" option (shown in the video) is not there. So how do I get my launch images into my Xcode project? PS: Apple does not allow me to write the URL for the youtube video here, but it's called "iOS App in Python with Kivy - Part 15: App Icon and Launch Screen"...

Hi! I tested my app on an iPhone 8 simulator in Xcode without problems, but when I tried to run it on a physical iPhone 5s I get an error saying that I can't write a file. Why? Where do I change that?: PermissionError: [Errno 1] Operation not permitted: 'geo-esp-train.cfg' 2021-02-28 23:09:59.085006+0100 geo-esp-training[457:91293] Application quit abnormally! 2021-02-28 23:09:59.294003+0100 geo-esp-training[457:91293] Leaving

Hi! I am new to Xcode and iOS apps, but I managed to build and test my app in the iPhone 8 simulator. I am using my Apple ID as 'developer team'. And I have approved that on my iPhone. When I deploy my app on my iPhone 5s (running iOS 12.5.1) it builds without problems, but when I try to run it by pressing the icon, the debug log shows this error: Got dlopen error on Foundation: dlopen(/System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation, 1): image not found Got fallback dlopen error on Foundation: dlopen(/Groups/System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation, 1): image not found 2021-02-28 23:09:59.023510+0100 geo-esp-training[457:91731] XPC connection interrupted Can any one please tell me what's the problem? I can add that I am using a MacBook Pro (Mid 2012) running MacOS Catalina 10.15.7 and Xcode Version 12.4. The app is actually a Python app using the Kivy interface framework. Thank you! Henrik R.
