All storyboard, xib file don't update the frame or constraint on Macbook Pro M1 with rosetta (Encountered an error communicating with IBAgent-iOS)

Question

I try to add constraint or load some of the storyboards or XIB files in my project but the storyboard doesn't update and can't see anything. This is my error screen capture:

In the first picture, the label is shown in the simulator but the storyboard doesn't.

In the second picture, The .xib file can't load any UI items

This is my error log:

Please help me.

If the problem persists, please add Xcode, OS and used xcode commandline tools version. — shallowThought, Dec 21 '20 at 09:13
Did you find any solution? I am also facing the same issue.. but I have to use rosetta for some reason. — Khushabu, Dec 30 '20 at 11:31
I have the same issue, I am running Xcode using rosetta, because of a pod that is not compiled for arm64 simulator. — Georgi Boyadzhiev, Jan 04 '21 at 13:20

I fixed this by not using Rosetta.

This does not help if you need to open in Rosetta for some other reason. – Andrew Sowers Dec 29 '20 at 15:35
This is the only answer that worked for me. I hope this will be fixed in next xcode release. – dgp Jan 05 '21 at 08:28
this is my work around too -- works for me so far but it sucks to switching back and front to using rosetta – CaffeineShots Feb 17 '21 at 18:47

Not using Rosetta. It worked for me. But the Cocoapods need to use Rosetta on Macbook Pro M1. This drives me crazy. Hope this will be fixed in next Xcode release.

To solve the problem on Apple Silicon:

With Rosetta enabled, just add arm64 in the excluded architectures on any iOS Simulator SDK in Build Setting section and build the project.
Then close Xcode, disable Rosetta and re-open Xcode.

Please relaunch Xcode and clean build everything. It worked for me.

Can you tell more detail about the way you clean? @Muskan Arora – Trí Chồn Dec 21 '20 at 06:28
Menu Bar → Product → Clean Build or you can use the shortcut Command+Shift+K – Muskan Arora Dec 21 '20 at 06:31

Close the simulator app.

Restart xcode.

Run.

If the problem persists, "erase content and settings" on the used sim.

Make sure the latest Xcode version is installed. Make sure the version of the used command line tools fits the used X code version (Xcode preferences).
