iOS13 application openUrl? (Obj-C) - objective-c

Question

How do you import files to your app on ios13?
Previously I could download a txt file in Safari and chose Copy to (app) and I would catch this in the app delegate open Url delegate. Doesn't work anymore.
The Copy To is still there in Safari, but it just dismissed Safari and nothing happens.
-- Edit:
Sorry, I was a bit unclear.
Previously, when downloading a file through another app (like Safari), the user could select to open this file in my app by tapping "Copy To (app)".
I would then catch this copy request through the appdelegate:
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
[...]
}
This delegate is not called in iOS13, only iOS12 and below.
I have tried finding a way to catch the "Copy to" request from other apps to no avail. There seems to be a new way of handling these things through a SceneDelegate?

Answer 1

In projects having SceneDelegate.swift file, should implement scene:openURLContext method.
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
print(#function)
print(URLContexts)
}
Output:
scene(_:openURLContexts:)
[
<UIOpenURLContext: 0x282fbca20;
URL: file:///private/var/mobile/Containers/Data/Application/A644621B-BD6C-443B-A9D1-A212EA59EE2E/Documents/Inbox/file.pdf;
options: <UISceneOpenURLOptions: 0x2823112c0;
sourceApp: (null);
annotation: (null);
openInPlace: NO>>
]

Version for Objective C.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSURL *url = [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey];
[[CommonController sharedInstance] handleExternalUrl: url];
return YES;
}
- (BOOL)application:(UIApplication *)app
openURL:(NSURL *)url
options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options
{
NSLog(#"application openURL: %#", url);
return [[CommonController sharedInstance] handleExternalUrl: url];
}
- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions API_AVAILABLE(ios(13.0)){
NSSet *c = connectionOptions.URLContexts;
if(c && [c count] > 0)
{
NSURL *url = ((UIOpenURLContext*)[[c allObjects] firstObject]).URL;
[[CommonController sharedInstance] handleExternalUrl: url];
}
}
- (void)scene:(UIScene *)scene openURLContexts:(nonnull NSSet<UIOpenURLContext *> *)URLContexts
API_AVAILABLE(ios(13.0)){
NSURL *url = [[URLContexts allObjects] firstObject].URL;
[[CommonController sharedInstance] handleExternalUrl: url];
}
