Xcode 8 takes forever to land at breakpoints

Question

I just upgraded my Xcode to Version 8.0 (8A218a) , when I insert some breakpoints and start the project, it just stops for about two minutes, then goes to one breakpoint, and then takes two more to go to the next.

Update: Step over also behaves the same (very slow).

Does anyone else use 8.0 to solve this problem?

Answer 1

I had the same problem. But this only happens in iOS8. This will not happen in a simulator or iOS9 +. So updating your version of iOS may solve this problem.

Answer 2

In my case, Xcode 8 automatically added many variables to the debug area, including those that are not available in the current context. Hiding the debug area greatly improved performance.

Answer 3

I had the same problem. In iOS10.Delete Breakpoints and disable source control. He was allowed.
