是什么导致 Xcode 9 的 iOS 模拟器出现视觉故障，我该如何修复它们？

Question

When running applications on the simulator with Xcode 9, I regularly experience a handful of visual glitches, which include red device identifier labels and content that duplicates itself and leaves pixel mess after it moves . I did not have these issues with Xcode 8.

These occur regardless of the OS of the simulator, I replicated the issue with iOS 11 and 10.

This might be unrelated, but I use a legacy version of iClipboard (6.0.0) and a similar glitch persists inside the search bar sometimes.

What causes these glitches and what can I do to fix them?

Answer 1

Re-installing macOS High Sierra latest version (10.13.4 (17E202)) will solve this issue, i had similar issue with my Mac-book Pro.

Please be sure you are hard formatting and then re-installing the fresh OS.

Answer 2

Try switching to the last Xcode. Xcode 11.5.0 is the latest current stable version.
