I&#39;m trying to figure out how to get the address of a lambda function within itself. Here is a sample code:

    []() {
        std::cout &lt;&lt; &quot;Address of this lambda function is =&gt; &quot; &lt;&lt; ????
    }();

I know that I can capture the lambda in a variable and print the address, but I want to do it in place when this anonymous function is executing.

Is there a simpler way to do so?

I have installed both Catalina and Xcode 11 from store and they are up to date:

 - Catalina: 10.15.1 (19B88)
 - Xcode: 11.2 (11B52)

Yesterday I have uploaded a new binary using `fastlane`. Today I got this message from Apple:

Since `Catalina` and `Xcode 11` are officially released why `Apple` still want me to use `Xcode 10` and `iOS 12`?

I have an HStack:

````
struct BottomList: View {
    var body: some View {
        HStack() {
            ForEach(navData) { item in
                NavItem(image: item.icon, title: item.title)
            }
        }
    }
}
````

I&#39;m trying to set a rounded border to a button but the border of the button is not correct.

Code:

    Button(action: {
            print(&quot;sign up bin tapped&quot;)          
    }) {
        Text(&quot;SIGN UP&quot;)
         .frame(minWidth: 0, maxWidth: .infinity)
          .font(.system(size: 18))
          .padding()
          .foregroundColor(.white)
     }
      .border(Color.white, width: 2)
      .cornerRadius(25)

Output:

[![enter image description here][1]][1]

As you can see the border at corner are cut-off.

Any suggestion what am I doing wrong?

I was working on an application with login and after login there are categories listed. And under each category there are some items listed horizontally. The thing is after login, main page appears and everything is listed great. When you click on an item it goes to detailed screen but when you try to go back it just crashes. I found this flow https://stackoverflow.com/questions/58404725/why-does-my-swiftui-app-crash-when-navigating-backwards-after-placing-a-navigat but i could not solve my problem. Since my project become complicated, I just wanted to practice navigation in swiftui and I created a new project. By the way I downloaded the latest xcode version 11.3. I wrote a simple code as follows: 

    NavigationView{
            NavigationLink(destination: Test()) {
                Text(&quot;Show Detail View&quot;)
            }
        .navigationBarTitle(&quot;title1&quot;)


And Test() view is as follows:

    import SwiftUI

    struct Test: View {
        var body: some View {
            Text(&quot;Hello, World!&quot;)
        }
    }

    struct Test_Previews: PreviewProvider {
        static var previews: some View {
            Test()
        }
    }

As you can see it is really simple. I also  tried similar examples on the internet but it does not work the way it suppose to work. When I run the project, I click the navigation link and it navigates to Test() view. Then I click back button and it navigates to the main page. However, when I click the navigation link second time, nothing happens. Navigation link works only once and after that nothing happens. It does not navigate, it des not throw any error. I am new to swiftui and everything is great but the navigation. I tried many examples and suggested solutions on the internet, but nothing seems to fix my issues. 

NavigationLink Works Only for Once

I&#39;m looking to create an EnvironmentObject that can be accessed by the View Model (not just the view).

The Environment object tracks the application session data, e.g. loggedIn, access token etc, this data will be passed into the view models (or service classes where needed) to allow calling of an API to pass data from this EnvironmentObjects.

I have tried to pass in the session object to the initialiser of the view model class from the view but get an error.

how can I access/pass the EnvironmentObject into the view model using SwiftUI?

I used to use autolayout add new constraints to make simple constraints to superview / relative view like this (for loooong time): 

[![enter image description here][1]][1]

However, recently after updated to the latest xcode (11.3.3 or just 11.3/11C29), I have this weird issue: when I set the constant = 0, they always generate the constraints in an unwanted way like this: 

[![enter image description here][2]][2]

And it seems default value is somehow 20 and making my view look so wrong (0 compared to 20?)

If I fix that by edit the constraint like this:

[![enter image description here][3]][3]

Then it&#39;ll correct again (the image is after edited the constraints, before edited it display constant = `Standard`)

I don&#39;t even know how to describe the issue, but how do I fix this new `add new constraint` to use my desire point instead of standard / default?

Update:

It seems to only happened when constraint to superview. No clue how to fix tho.

Update Apr-01-2020:

Xcode11.4 fixed this.

I recently updated my Xcode to 11.4. When I run the app on the device, i&#39;ve noticed that all my navigations item&#39;s titles gone fully black when being set from storyboard.
[![enter image description here][1]][1]

You can&#39;t change neither from code, the following line of code doesn&#39;t work anymore

```swift
self.navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.white]
```

I only make it work using some iOS 13 stuffs UINavigationBarAppearance

```swift
@available(iOS 13.0, *)
    private func setupNavigationBar() {
        let app = UINavigationBarAppearance()
        app.titleTextAttributes = [.foregroundColor: UIColor.white]
        app.backgroundColor = Constants.Color.barColor
        self.navigationController?.navigationBar.compactAppearance = app
        self.navigationController?.navigationBar.standardAppearance = app
        self.navigationController?.navigationBar.scrollEdgeAppearance = app
        
        self.navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.white]
    }
```

Can somebody explain me why??? This is a crucial bug, or some new hidden feature?

I have just updated to Xcode 13 Beta and I am about to upload my first build to App Store using this version of Xcode. This version of Xcode shows a new App Store Connect distribution option which I previously haven&#39;t seen:

&gt; Manage Version and Build Number  
&gt;  
&gt; This will change the version and build number of all content in your app to 1.2 (3).

[![enter image description here][1]][1]

I have already increased my version and build number from Xcode before archiving. What should we do here? If it is an automated way of build increment, what are the benefits of using it?

I try to get my local development in Chrome back running, but Chrome prevents that, with the message that the certificate is invalid. Even though it could not be the date of the certificate, as you can see in the screenshot of it:

[![enter image description here][1]][1]

I just wonder why there is no advanced &gt; option to proceed anyway to see the website and being able to locally develop the app.

A few more things to mention:

 - The local development runs on
   https://local.app.somecompany.com:4200/. It can&#39;t be just localhost,
   because otherwise our authentication http-only cookies won&#39;t work in
   Chrome.
 - Therefore the host file under etc/hosts was adjusted to
   point to the localhost IP adress (127.0.0.1).
 - The certificate was
   generated with openssl according to this [tutorial][2] and this
   [repo][3]
 - The certificate works for a colleague with the exact same
   Chrome version but with a MacOS version 10.14.6 (mine right now is
   MacOS 10.15.1)
 - The chrome flag(chrome://flags/#allow-insecure-localhost) does not change anything
 - Also works in firefox on my laptop.

Can&#39;t find anything online that helped me to solve this so far, so I would be extremly thankful, if anyone has some more ideas what I could try!?
