XCode App Stuck on Launch Screen No Error Log

Question

I use XCode 8.1 and using Swift 3. The app suddenly decided to stuck on the launch screen when I run it from XCode with no error log. I put breakpoint in the didFinishLaunchingWithOptions but it isn't triggered. The app doesn't shut itself completely, just keeps displaying the launch screen. Interesting thing is that when I tap the app on the device without XCode, the app works with no problem. Any idea why this is happening?

What I tried

• Removed Derived Data
• Restart XCode
• Restart the computer
• Uninstall the app
• Clean/Build

Below is what I get when it crashes.
