Xcode Clipboard: Copy & Paste stuck

问题:

I've just updated to Xcode 9.4.1 and experienced an issue with the clipboard being cleared randomly.

So I select a text, hit CMD+C, then go to the position I want to paste it, hit CMD+V, but either

• it plays the system alert sound and doesn't paste anything, or
• it pastes a previous snippet that I copied earlier.

Update

Still remains with Xcode 10.1

Update 2

Still remains with Xcode 11

Turning off the 'Automatically Sync Pasteboard' option in the Edit menu of the Simulator works for me. I read it in Apple forums

回答2:

This really helps! Just uncheck the Automatically Sync Pasteboard

The accepted answer doesn't work for me. See my comment there. The problem is with the Handoff.

I had the Handoff option enabled in OS X Settings > General.

After unchecking that option, I have the clipboard synced and no simulator freezes.

Also read in the Apple forums that closing the simulator while working fixes this issue. So if it happens to me I close the simulator and copy-paste works fine from that point forwards.

Haven't tried it yet but I have feeling that Eva's answer is correct in that the simulator is trying to sync your pasteboard.

** Edit **

Can confirm that Eva's answer works and I no longer have this issue when I turn of automatic syncing on the simulator
