DocumentPicker Extension immediately stopped on clicking on the icon - ios8

I have created the document picker extension(Both File provide and document picker , with the default implementations) and when i try to open the extension using the DocumentPickerViewController, its immediately closing the DocumentPickerViewController by showing the below issue
plugin com.apple.UIKit.fileprovider.default invalidated.
I have setup the basic app groups and iCloud entitlement as well, Which are all fine. Even from the documentViewController the default iCloud is working perfectly fine.
Actually i am testing the extension using the same container application.
If somebody can provide some insight about this behavior, it would be a great help !!
Thanks,
Vishnu

I got the issue, actually the value of NSExtensionFileProviderDocumentGroup key was put incorrectly put on the info.plist of the file provider extension by XCode by the time of adding the App group.
Then I compared the files with the NBox sample from Apple and finally figured it out.
So sometimes beware of XCode automatic actions, make a cross check so to save to time.

Prevent or clear app state persistence for MacOS SwiftUI Document Based App

I am developing a MacOS Document based app using SwitfUI on MacOS 12.0.1 using Xcode 13.1 on a MacbookPro M1 Pro. I am encountering an issue that the app is always re-opening the document browser at the last used directory. Which is OK when it is on the Machine but a pain if the last used was on a network drive. I am trying to find a way of suppressing this "always restore using the last directory" mode of operation.
I have tried using the #NSApplicationDelegateAdaptor approach and implementing;
func applicationSupportsSecureRestorableState(_ app: NSApplication) -> Bool {
print(#function + " returning false")
return false
}
within my NSApplicationDelegate class, which does get called (although it seems sometimes after the dialog is presented), however this does not stop the app secretly remembering the last directory.
Does any know where this information might be being hidden or if it can be suppressed ?
I have looked for, but cannot find, a way of injecting a starting directory into a DocumentGroup as a possible solution.
TIA Alan.
Ok, for anyone who ends up here looking for a similar issue.
After a chunk of digging I found the answer, for me, was to add
UserDefaults.standard.removeObject(forKey: "NSNavLastRootDirectory")
into the app startup. It was also suggested to do
UserDefaults.standard.removeObject(forKey: "NSNavLastCurrentDirectory")
However, just doing the first appears to suppress the file open dialog, doing both causes the file open dialog to open with the user Documents directory.

Class PLBuildVersion is implemented in both frameworks

iOS 10 / Xcode 8 GM build getting the below, never had it before on Xcode 7. Any ideas?
objc[25161]: Class PLBuildVersion is implemented in both
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices
(0x12049a910) and
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices
(0x1202c4210). One of the two will be used. Which one is undefined.
(NOTE: Only seems to happen in simulator, does not appear on real device).
Main Idea
Main idea is simple:
If your app (or dependencies, such as Pods) uses framework, that uses explicit (or implicit) PhotoLibraryServices.framework or AssetsLibraryServices.framework as dependency, Xcode warns you (even if you are using only one of them). It might be Photos/PhotosUI.framework or AssetsLibrary.framework, or another (I don't have full list of dependencies, but it is possible).
What is the problem?
Class with name PLBuildVersion is defined in both PhotoLibraryServices.framework and AssetsLibraryServices.framework. Class name is unique in Objective-C (you can't define 2 classes with same name), so it is undefined which one will be used in runtime.
However, I think that it will not be a problem, because both classes have same methods and fields (checked this with disassembler) and I guess that both were compiled from the same source.
Radar is already sent.
As per answer from Apple employee on Apple's Developer Forum:
You don't control either of the class sources listed, so there isn't anything you can or should do – aside from Reporting a Bug.
I was unable to find a way to get rid of the warning, but if you want to prevent the app from crashing, you need to provide a description for why you are accessing the camera, photo library, etc. This is new in iOS10.
Input the following into your Info.plist file.
Photo
Key: Privacy - Photo Library Usage Description
Value: $(PRODUCT_NAME) photo use
Camera
Key: Privacy - Camera Usage Description
Value: $(PRODUCT_NAME) camera use

I find you can get this error merely by using a UIWebView. My solution was to replace my use of UIWebView with WKWebView.
I had this after adding Answers on Fabric to my project.
Deleting derived data did the trick for me. (shift alt command k in XCode)
Edit a year later:
After deleting derived data, always exit XCode and start it again.
In unrelated cases I have the impression that deleting derived data does not clear XCode’s in memory caches of the derived data.
Resetting the iOS simulator fixed this for me. Simulator -> Reset Content And Settings.
In my case this warning started to appear after opening a second xcode project and running the second app on the simulator. After changing back to the first app, the warning started to appear. I just quit the Simulator and Xcode and reopened my project. The warning disappeared after that. If that doesn't solve it, proceed with the other answers. Xcode can be really picky sometimes.

QLPreviewView can not show the quicklook preview in sandbox

I use QLPreviewView to show the quicklook preview in the app. Without sandbox, this works well, but once change the app to sandbox, the preview can not show up.
I found the error in Console: QuickLookUIHelpe(20786) deny file-read-data XXX.
I have used the security-scoped bookmarks & com.apple.security.files.user-selected.read-write to grant access the user home dir, then:
[allowedURL startAccessingSecurityScopedResource];
self.myPreiviewItem.myURL = fileURL;
self.myQLPreviewView.previewItem = self.myPreiviewItem;
[self.myQLPreviewView refreshPreviewItem];
[allowedURL stopAccessingSecurityScopedResource];
with these, I can delete files of user home dir, but the QLPreviewView can not work.
I do not know what is the difference between these 2 scenes, does QLPreviewView need more for sandbox?
If I add com.apple.security.files.downloads.read-only into the entitlement, the files in "Downloads" can be previewed, but other files of user home dir can not be previewed.
Finally I have found the solution!
refreshPreviewItem is an async call, so before Mac finishes loading the preview, the following api stopAccessingSecurityScopedResource immediately shutdown the access, as a result, Mac failed to load the preview successfully.
so the solution is: do NOT call stopAccessingSecurityScopedResource here, keep the allowedURL's access right until you do not need the QL preview function, and then call stopAccessingSecurityScopedResource there, such as when closing the window.
I encountered this, or at least a similar, issue a while back (in Mavericks).
This is why I started asking users for access to parent folders of files they wish to Quick Look. Feel free to look at how I do it in this app of mine, version 1.1 at the time of this writing. Just go into Chikoo → Preferences… → Folder Access. Here are two screenshots:
I confess that this is not a great solution. It’s a compromise that I came up with to work around the problem.

Using OSX Security-Scoped Bookmarks in a Firemonkey app

I have been developing an OSX app with Delphi XE3 and running into various problems. The latest one is with the sanboxed version built for the Apple Appstore.
The user has to select an arbitrary folder and the app needs to get access to it. Since there is a problem with the OpenDialog, I had to turn to drag-drop functionality instead.
The user drags a folder to the app, the sandbox gives the app temporary access to it and all works properly.
To preserve the access to this folder when the app is restarted I have to use the so-called "security-scoped bookmarks"
I am having two issues with them:
1) How to add the "com.apple.security.files.bookmarks.app-scope" entitlement to an XE3 firemonkey app? It is not available in the Project Options->Entitlements. If I add it manually in the ".entitlements" file it gets overwritten when the app is built.
So is there a way to add a custom entitlement that is not in the list in the project options?
2) To create the bookmark I should use the NSURL.bookmarkDataWithOptions method. I think it should be used like this, but I am not sure of the exact syntax:
var
URL: NSURL;
Err: NSError;
Data: NSData;
...
URL := TNSURL.Create;
Data := URL.bookmarkDataWithOptions(NSURLBookmarkCreationWithSecurityScope, nil, #Err);
...
Maybe there should be a call to Wrap(...) instead of Create.
I have not yet experimented with it, because it is pointless without the answer to issue 1).
It seems no one has written anything about these problems for Delphi, but I hope someone here has experience with that.
Thanks in advance.
Edit:
For problem 1) I tried to add edit manually the ".entitlements" file in the OSX32 folder and set it to read-only to prevent it from being overwritten. It was too easy to be true of course, because the linker complained that the file can not be modified...
OK, I finally found the way to manually add entitlements that are not available in the Project Options > Entitlements.
Instead of selecting the "App Store" build in the Project Manager you have to select a Normal release build and deploy the application as usual.
The application gets deployed in the PAServer scratch-dir as APP package. Inside this package there is an "Entitlements.plist" file, which is in XML format and can be edited with a text editor. It is quite obvious how to add new entitlements once you open the file.
After it is edited, the app has to be code-signed manually and a package has to be prepared. It is slightly more complicated than using the Delphi IDE, but there are instructions about it on the Embarcadero and Apple websites and it actually went without problems.
Still haven't tried the bookmarkDataWithOptions functions.
An alternative could be to deactivate the checkbox for the entitlements-file in the deployment page.
But attention: Evry time you change between Build/Release or App Store/Normal, delphi activates the checkbox. That means you have to deactivate it again in the deplayment-page, to avoid the transfer of this file to the mac PC.
By the way: Do you have tryed meanwhile the StartAccessingSecurityScopedResource function?
In the MacApi.Foundation unit the function is not declared in the NSURL interface.
Do you have found a way to use this function?

Unable to process application Info.plist validation at this time due to a general / IO error [duplicate]

I am creating a newsstand application. the application is ready, now i am trying to upload the app in apple store using Application Loader. While uploading the zip file its showing the error message as
Unable to process application info.plist validation at this time due to a general error (1095)
I googled this in the net, but did not find the solution still.
This is clearly an Apple server issue, not an Xcode/iOS/OSX issue. Just wait patiently and Apple's servers will catch up to the traffic, or solve whatever issues they're having at their end.
If you're anxious, feel free to just sit there and restart Xcode until it works - but it's not restarting Xcode, only the time you waste that's solving the issue.
While you're waiting, run your apps in Instruments and solve some performance issues ;)
I just had this error. I waited an hour and tried again with the exact same build and it was all good. Vote for it being Apple's temporary glitch.
I had the same problem. I closed Xcode, restart my computer and it worked.
One possible problem to this is corrupted png files. The png files should not be interlaced
I found a solution to the problem.
If you're using Xcode 4+, you don't have to use Application Loader anymore. Instead you should archive your project in Xcode (Product->Archive). It will then open the organizer, where 3 buttons are displayed. Hit the submit button.
If you've created an entry for your app with Itunes Connect, you should be able to choose that from the list, and then select your distribution profile. Then hit the next button, and you should get a message, that tells you, that your app has been submitted.
At least that worked for me.
Use Application Loader.
I'm getting this a lot today.
Application Loader worked.
XCode > Project > Archive
XCode > Organizer > Distribute > Enterprise/add Hoc > Save As
Saves as YOURAPP.ipa.
Make sure Save for Enterprise Deploy remains UNCHECKED.
Download latest Application Loader.
tap 'Deliver Your App'
make sure new version in itunes connect in WAITING FOR UPLOAD state
Click on Activity... button
TIP: open Console.app to see XCode Validation errors
Click on ALL MESSAGE on list of logs on right.
Then in search enter 'XCode' or 'Application Loader'
to monitor any errors with your upload.
Note:
I did all this and still got email about missing 120x120 icons.
Forgot to update them in Build Target > General Tab
List of new icon requirements for iOS7
http://www.icenium.com/resources/forums/icenium-general-discussion/missing-recommended-icon-file
Another reason why this can happen is the duplicate product name. Despite your app names, executable names, display names or bundle IDs are different, if the product name exists in your current apps this error is gonna occur.
"The server returned an invalid response. This may indicate that a network proxy is interfering with communication, or that Apple servers are having issues. Please try your request again later.""
Reset The internet connection.
Reopen the xcode.
Set the profile again.
Clean build.
And Archive the build.
Works perfect for me (With in 5 minutes no need to wait).
Thanks
It's just the time, because you can't control Apple's Server's traffic problem, We all merely become the victim of that..So cut the long story short...
By restarting XCODE may work but everyone as in my case, i tried by restarting XCODE, SYSTEM, ROUTER and anything and everything possible, only error name had changed from "The network connection was lost" to "The request timed out" and vice Versa..!
Just think at what time less people would be accessing the sever...
PS: Only perseverance can help you in this way..keep redialing..And WAIT and WATCH:P
I solved ... :)
Please remove all your icons and splash image also remove icon Files and icons File( IOS 5 ) from info.plist and then add all your icons to app bundle ...
After this update info.plist iconFiles field add desired name of icons....
And last but not least remove Provisioning profile from developer portal and recreate it ...
Clean your build and Archive it and using Application Loader submit it to AppStore ...
it work for me and i think it may help you...
Not every time not it is Apple server issue,sometime we did some bad linking according to me :)
