Failed to create IXPlaceholder for app bundle ID

Question

I have copied Xcode Version 9.0 (9A235) from my friends Macbook and replaced with my Xcode 8.3.2

When I run my app in any simulator say iPhone 8 or iPhone X, I am getting same error:

Failed to create IXPlaceholder for app bundle ID com.*****.****

Simulator is showing black screen and not loading iOS 11

Answer 1

Xcode shouldn't really be simply copied off a system where it's already installed onto a new system. The best solution would be to download the Xcode 9 GM from the developer site, or the Mac App Store when the Xcode 9 update goes live in a few days. However, before then, you could try running xcode-select --install to see if the additional required components are installed with that
