Updating Godaddy's name servers? Good luck

I have used Godaddy for a long time. By the way I have got a critical issue when I update name servers of a domain.

Today I tried to update the name servers of a domain to Godaddy’s default name servers and then it was messed up. The existed name servers were mixed up with Godaddy’s default name servers and then I cannot use the domain anymore.

Then I called Godaddy’s customer support and they said they had an issue on it. As a result, they said that I have to wait for 5 days to get the domain working. It was my second time to face this issue.

Someone who uses their Godaddy domain for a critical use has to think about updating name servers seriously. I think that Godaddy has a big problem on their system. It happens twice and they haven’t fixed it.

I will try to transfer all my domains to other service provider as soon as possible.

Free iPad Pro Duel screen? Give up using Sidecar

I have used Duet or Astropad for making iPad Pro as a second display. Then I tried to use Apple’s Sidecar which is a new feature of Mac OS Catalina. By the way it seems too unstable.

I frequently meet a freezing issue, a black screen and so on. Eventually I changed to Duet Display which provides much better reliability. Also, it provides more high-end resolution. But I don’t think whether or not this feature needs. Because the size of texts is too small to read.

I feel that Apple makes their product quality worse since Steve Jobs was gone. As a long Apple fan, I feel disappointed.

Still Touch ID is better than Face ID

When iPhone X was launched I bought and used it and then it took a short time to change from it to iPhone 8 Plus which has Touch ID. The reason why I changed was because Face ID wasn’t reliable and better than Touch ID. After several years my iPhone 8 Plus was broken and I bought iPhone 11.

Still Touch ID is better than Face ID. I don’t know how difficult putting Touch ID into the screen of iPhone is. Then I think that Apple is still working on it. Recently Samsung tried it and then I read comments saying many users do not satisfy with it.

Apple iPad Pro Sidecar with Mac OS Catalina

After Apple released the official version of macOS Catalina and I tried to use Sidecar with my iPad Pro. It seems okay. But it doesn’t work sometimes. For example, sometimes iPad Pro screen became just a black screen and I have to change the display option between Mirroring and Separated mode.

Today I updated the latest Mac OS Catalina and iPadOS 13.1.3 and now it feels more stable than before. If you have any issue like me please try updating your Mac OS and iPadOS.

@Published property wrapper in a subclass doesn't send a callback

I worked on an app using SwiftUI and Combine framework. Then I used @Published property wrapper to publish a stream data from a property in a ViewModel class. By the way when I assign a new value to the property and it doesn’t send a callback to the counterpart SwiftUI view. Then I looked through a similar question in the stack overflow.

Then I followed the answer. But it doesn’t work in my case. So I declared objectWillChange in the subclass and now it works. I think that SwiftUI and Combine framework are not stable yet. So you might have this kind of issue.

// ViewModel 
var objectWillChange = PassthroughSubject<Void, Never>() 

var value: String = "Select" {
  willSet {
    self.objectWillChange.send()
  }
}

// View 
var body: some view {
  Text(self.viewModel.value)
}
