When upgrading a project that is compiling and running fine on .NET Core 1.0 or 1.1, updating the target framework to .NET Core 2.0 (`netcoreapp2.0`) causes the build to fail with the following error:

     error NU1003: PackageTargetFallback and AssetTargetFallback cannot be used together. Remove PackageTargetFallback(deprecated) references from the project environment.

What is the reason for this error and how can it be resolved to make the project build again?

I&#39;ve been struggling a lot to properly implement Stomp (websocket) **Authentication** and **Authorization** with Spring-Security. *For posterity i&#39;ll answer my own question to provide a guide.*

&lt;br /&gt;

### The Problem
Spring WebSocket documentation (for Authentication) looks unclear ATM (IMHO). And i couldn&#39;t understand how to properly handle **Authentication** and **Authorization**.

&lt;br /&gt;

### What i want
- Authenticate users with login/password.
- Prevent anonymous users to CONNECT though WebSocket.
- Add authorization layer (user, admin, ...).
- Having `Principal` available in controllers.

&lt;br /&gt;

### What i don&#39;t want
- Authenticate on HTTP negotiation endpoints (since most of JavaScript libraries don&#39;t sends authentication headers along with the HTTP negotiation call).

I have recently migrated some code to new iOS 11 beta 5 SDK. 

I now get a very confusing behaviour from UITableView. The tableview itself is not that fancy. I have custom cells but in most part it is just for their height.

When I push my view controller with tableview I get an additional animation where cells &quot;scroll up&quot; (or possibly the whole tableview frame is changed) and down along push/pop navigation animation. Please see gif:

[![wavy tableview][1]][1]

I manually create `tableview` in `loadView` method and setup auto layout constraints to be equal to leading, trailing, top, bottom of tableview&#39;s superview. The superview is root view of view controller.

View controller pushing code is very much standard: `self.navigationController?.pushViewController(notifVC, animated: true)`

The same code provides normal behaviour on iOS 10.

Could you please point me into direction of what is wrong?


EDIT: I have made a very simple tableview controller and I can reproduce the same behavior there. Code:

    class VerySimpleTableViewController : UITableViewController {

        override func viewDidLoad() {
            super.viewDidLoad()

            self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: &quot;Cell&quot;)
        }


        override func numberOfSections(in tableView: UITableView) -&gt; Int {
            return 1
        }

        override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
            return 4
        }


        override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -&gt; UITableViewCell {
            let cell = tableView.dequeueReusableCell(withIdentifier: &quot;Cell&quot;, for: indexPath)

            cell.textLabel?.text = String(indexPath.row)
            cell.accessoryType = .disclosureIndicator

            return cell
        }


        override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
            tableView.deselectRow(at: indexPath, animated: true)

            let vc = VerySimpleTableViewController.init(style: .grouped)

            self.navigationController?.pushViewController(vc, animated: true)
        }
    }



EDIT 2: I was able to narrow issue down to my customisation of UINavigationBar. I have a customisation like this:

`rootNavController.navigationBar.setBackgroundImage(createFilledImage(withColor: .white, size: 1), for: .default)`

where `createFilledImage` creates square image with given size and color.

If I comment out this line I get back normal behaviour.

I would appreciate any thoughts on this matter.

Weird uitableview behaviour in iOS11. Cells scroll up with navigation push animation

Using the latest Xcode 9 beta, I&#39;m seemingly completely unable to access properties on Swift classes. Even odder, I can access the class itself to instantiate it or whatever, but completely unable to access properties on it.

So if I have this Swift class:

    import UIKit
    
    class TestViewController: UIViewController {
        var foobar = true
    }

And I try to do this:

    TestViewController *testViewController = [[TestViewController alloc] init]; // success
    testViewController.foobar; // error

What exactly am I doing wrong? New project with Xcode 9.

I had been using the following code prior to iOS 11 to customize the appearance of the `UISearchController` search bar:

    var searchController = UISearchController(searchResultsController: nil)
    searchController.searchBar.setDefaultSearchBar()
    searchController.searchResultsUpdater = self

    if #available(iOS 11.0, *) {
        navigationItem.searchController = searchController
    } else {
        tableView.tableHeaderView = searchController.searchBar
    }

    extension UISearchBar {
        func setDefaultSearchBar() {
            self.tintColor = UIColor.blue
            self.searchBarStyle = .minimal
            self.backgroundImage = UIImage(color: UIColor.clear)
            let searchBarTextField = self.value(forKey: &quot;searchField&quot;) as! UITextField
            searchBarTextField.textColor = UIColor.white
            searchBarTextField.tintColor = UIColor.blue
            searchBarTextField = .dark
        }
    }

However, the appearance of the search bar fails to update when running the same code on iOS 11.

Much of the attention to this question so far has focused on the text color of the search bar. I am looking at more than this - the background color, tint color, the search indicator, clear button color, etc.

I have been using Keyboard notifications without any problem and getting exact height of Keyboard.

    - (void)keyboardDidShow:(NSNotification *) notification{
        CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    
        NSLog(@&quot;%f&quot;,keyboardSize.height);}

but with iOS 11 the size of keyboard is 0 when the notification is called. 

What is the problem occurring in this scenario? I am using xcode 9 Beta 5

I downloaded a project from GitHub, then pod the following files, some of which are written by OBJ-C and I used a bridge header.

    pod ‘SnapKit’
    pod ‘MJRefresh’
    pod ‘Alamofire’
    pod ‘Kingfisher’
    pod ‘MBProgressHUD’
    pod ‘pop’
    pod ‘EVReflection’
    pod ‘StreamingKit’
    pod ‘iCarousel’
    pod ‘ReflectionView’

When I run the project with Xcode 9.0 beta 2, but unfortunately the error log as follows :

&gt; for bridging header
&gt; &#39;/Users/ringo/Downloads/EvoRadio-master/EvoRadio/Resources/EvoRadio-Bridging-Header.h&#39;

I have googled, but no such issue.The error means it needs a PCH file?

Several years ago I released an app (a free game) for iOS, which was largely unsucessful, settling to around an average of 5 downloads a month (terrible, I know). However, I recently happend to notice a huge (relatively) spike in downloads, up to around 300 downloads over the last 10 days. 

Something seems strange about this latest batch of downloads however, for one thing they are all from China (My app is only localized for English, and never marketed outside the U.S.), and the &quot;Active devices (opt-in only)&quot; statistic shows 3 devices used over that same time period. 

Even stranger, the &quot;Product Page Views&quot; statistic shows only 6 views over this same period that had 300 downloads?!

Is something nefarious going on, or might there be a benign explanation for this huge spike in downloads?

If anyone is curious, or if it helps find the cause, the app is Acorn Mayhem, [as found here][1]. (Note: this is not intended as self promotion, and if including the link violates stack overflow rules, feel free to edit it out)

in response to being put on hold:
This question appears to have been put on hold as &quot;off topic&quot;, I don&#39;t belive it should be, it does involve tools used directly and exclusively for programming (iTunes connect, which is only used by programmers) It would not be seen by the people who actually use it if it was on superuser, and I think the number of other people who have experienced the same problem and replied in a short time shows that it is on topic and helpful to a large portion of the programming community.

There is a thread on Apple forums about the issue https://forums.developer.apple.com/thread/84146

I have my iPhone connected to Xcode. It used to work just fine recently. I see it in the Devices and Simulators section, but when I try to compile my app, it says:

 &gt; D&#39;s iPhone 6S is not connected. Xcode will continue when D&#39;s iPhone 6S is connected.

In the Devices and Simulators I see it as disconnected.

I tried restarting the phone, turning it&#39;s wifi on and off. It&#39;s connected to the same wifi network, I tried restarting Xcode, nothing. I run Xcode 9, Beta 6 at the moment. Does anyone has similar issue and hopefully know how to solve it?

My iOS app uses a custom height for the `UINavigationBar` which leads to some problems on the new iPhone X. 

Does someone already know how to **reliable** detect programmatically (in Objective-C) if an app is running on iPhone X?

**EDIT:**

Of course checking the size of the screen is possible, however, I wonder if there is some &quot;build in&quot; method like `TARGET_OS_IPHONE` to detect iOS...

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
        CGSize screenSize = [[UIScreen mainScreen] bounds].size;
        if (screenSize.height == 812)
            NSLog(@&quot;iPhone X&quot;);
    }

**EDIT 2:**

I do not think, that my question is a duplicate of the linked question. Of course, there are methods to &quot;measure&quot; different properties of the current device and to use the results to decide which device is used. However, this was not the actual point of my question as I tried to emphasize in my first edit. 

The actual question is: **&quot;Is it possible to directly detect if the current device is an iPhone X (e.g. by some SDK feature) or do I have to use indirect measurements&quot;**?

By the answers given so far, I assume that the answer is &quot;No, there is no direct methods. Measurements are the way to go&quot;.

I have problem with application using XIBs without autolayout. I don&#39;t know if this is important information. 

I have UILabel with 2 lines using word wrap. In iOS 10 word wrap was working correctly, and first line contained one word + special character, for example ampersand. Example:

[![UiLabel on ios 10][1]][1]


Then on iOS 11 word wrap is working somehow wrong and puts ampresand to the second line:

[![UiLabel on ios 11][2]][2]

This is problematic as longer words, that normally fitted on second line now are not being shown correctly. Any idea what has changed? I know about safeArea but it doesn&#39;t look like reason. Any ideas how to move that ampersand to the top where is plenty of space for it?

With a certain project in Xcode 9 beta 6 when I try to Upload to the App Store I get:

[![enter image description here][1]][1]

I am the &quot;Admin&quot; role for this account.

* All contracts are up-to-date
* I tried removing/re-adding my account from Xcode prefs several times
* Submitting for the same project from Xcode 8 works (however I need to upload from Xcode 9 for this project because it links against iOS 11 beta)

Another developer on the team is seeing the same thing so this seems like it might be common. Anyone find a workaround?
