Xcode Storyboards INCREDIBLY Slow after 7.3 Update

Ever since I installed the Xcode 7.3 update last night, working with Storyboards has become a nightmare. Simply changing the 'hidden' property of a UIButton takes 30 seconds now. Really not sure what changed, but it makes UI updating almost impossible.

I've uploaded a clip here (I click the hidden property and you can see how long it takes): https://youtu.be/uB5VvXEv0_U

Same issues here as well, actually on 2 different computers and different projects as well. Worked really fast before the update, now even scrolling causes the spinner to show and xcode freezes up for about 10-15 seconds.

I've since installed a second copy of Xcode (7.2.1) and the issue is not present there. Hopefully Apple can make an update to resolve this quickly.

I bought a top of the range mac book pro about a month ago. Initially loaded 7.2 - no problem. Updated to XCode 7.3 and the storyboards are a disaster. They are unbelievably slow and display things incorrectly.

Same here, after updating to 7.3 storyboard hangs after any movement, scroll or edit.

It's insanely slow. This morning I waited 30+ seconds (hello mr spinny beachball) for xcode to take me to the storyboard.


THIS MUST BE FIXED. NOW.

I had the same issue, but then I switched back to XCode 7.2.1 aaand the issue was still there.


What I have figured out is that certain combinations of components can cause issues with autolayout which makes Interface Builder incredible slow.

For me the combination was a segmented control inside a navigation bar.

When i removed it and placed segmented control in a simple view Interface builder become smooth again.


Hope this will help someone.

So looks like we are all having issues with Xcode since 7.3. No resolution. Guess we will just have to wait until a new update is available.

Are you editing your storyboard on an external display? If so, try moving it back to your built-in retina display. For me, if I edit a storyboard on my external, non-retina, display, Xcode becomes unusably slow and changing anything in the inspector panel takes an eternity. If I move the Xcode window containing my storyboard back to my built-in retina display, the problem quickly goes away. This is not fixed by the 7.3.1 update.

XCode Version 7.3 (7D175)


I had ~60 "misplaced views" nested in 5 different view controllers and once I went through and cleaned them up, it went from 15 seconds down to 3 seconds to switch between story board and code or the storyboard and the image atlases. 3 seconds is still not good, but it is much more managable than 15 seconds.

Is anyone else having this same issue in Xcode 8 (currently beta 2)? I see the same - if I move the Xcode window to my MBP display first, then open the storyboard, it is fine, but if I open it while the Xcode window is on my external Apple Thunderbolt display, the CPU churns at 100% (about 60/40 Interface Builder Cocoa Touch Tool / Xcode) until I switch back to a source file. I see this with a larger stroryboard (13 View Controllers), but can't reproduce with a simple one. Submitted bug # 27286305.

I'm having the same issue. Even with only a handful of view controllers. I put up with it for many painful weeks. At least there's a workaround...
