Hi João, I am a 9-year old app developer who started making apps last year! I have 2 apps on the App Store, MathFlash Fun - https://apps.apple.com/us/app/mathflash-fun/id1502858843 and Building Blox AR - https://apps.apple.com/us/app/building-blox-ar/id1519633347?mt=8&ign-mpt=uo%3D4 When I am making apps, CodeWithChris's YouTube Channel was very helpful. I also learned some basic Swift coding. I think you should create an Xcode project and just experiment with all the different parts! Congratulations, NSApps

Turn off Ask Siri in Siri settings then turn it on again

As of now, No

I have Xcode 12 beta 3 and I have never seen this issue!

What is the deployment target? If it is iOS 12.4.8 or earlier, add this to the AppDelegate class: var window: UIWindow?

I recently figured to that on devices iOS 13.4 or later this app lets you preview SwiftUI views when you are building them! It is not malware and has nothing to do with your PowerPoint theme!

Same here with the public beta I tried to install on external SSD Encountered this issue - https://developer.apple.com/forums/thread/655251 Force Rebooted my Mac Saw An error occurred installing macOS. You can try again to complete the installation"

I have iOS 14 public beta 5, but I can't see App Clip Testing or Local Experiences in Developer Settings!

It is now available - apps.apple.com/us/app/mathflash-fun-desktop-edition/id1516195356?mt=12&ign-mpt=uo%3D4 - https://apps.apple.com/us/app/mathflash-fun-desktop-edition/id1516195356?mt=12&ign-mpt=uo%3D4

Why don't you clean the build folder, re-archive it, and try again (They support Xcode 12 beta in TestFlight now)

Step 1: Go to My Apps>AppName where AppName is the name of your app! Step 2: Go to Pricing and Availability Step 3: Scroll to the Availability section Step 4: Click edit next to All Countries and Regions Step 5: Search for China and deselect it That's It!

I tried to run Big Sur from an external disk, but I ran into this - https://developer.apple.com/forums/thread/655251 problem!

UIKit UIs are made using the drag-and-drop Interface Builder. UIKit apps connect to the code using outlets and actions. SwiftUI UIs are made programmatically. SwiftUI code is controlled from the same code as the UI. SwiftUI is only in iOS 13.0 and later!

In Settings.app/Developer click clear trusted computers. when you plug in again click trust and enter your passcode.
