ODUIThreadGuard is a guard to help me check if you make UI changes not in main thread. Highly recommand you add this file to your project as early as possible.

• Passive implementation
• Throw an assertion if setNeedsDisplay, setNeedsLayout, or setNeedsDisplayInRect: is called for instantion of any UIView
• Get the thread stack to help you locate where you make the mistake

Use CocoaPods or Cathage or just pull the ODUIThreadGuard.swift file into your project.

You can change the pre compile flag to change the setting, in default, this only runs in DEBUG mode, so won't affact users in Release.

• iOS 8.0+
• Swift 3

The main development of ODUIThreadGuard is based on Swift 3.

Follow and contact me through email. If you find an issue, just open a ticket on it. Pull requests are warmly welcome as well.
