Rosetta Simulator Run Destination not showing in Xcode 26

Question

I am currently using Xcode 16.4 on macOS Sequoia 15.7 for iOS development. On this setup, I am able to set and use the Rosetta Simulator in the run destination without any issue. [enter image description here

On the same macOS Sequoia 15.7 machine, I also installed Xcode 26.0 and can still select and use the Rosetta Simulator in the run destination. enter image description here

However, on a different MacBook, where I freshly set up macOS Tahoe 26.0 and installed Xcode 26.0, I noticed that the Rosetta Simulator option is missing from the run destination when using the same iOS project. (https://i.sstatic.net/F0BTsKJV.png) Is there any additional configuration or step I need to perform to enable Rosetta Simulator on macOS Tahoe 26.0? I would appreciate any suggestions or solutions. Thanks in advance! ^_^

• Nam Hoàng: same issue here. does anyone have any solutions?
• matt: Rosetta is going away, so it would be best to get off your dependence upon it.

Answer 1

The solution for me was to force Xcode to download a "Universal" version of the iOS 26 simulator rather than the default "Apple Silicon". Here are the steps:

1. In the top menu: Xcode -> Settings -> Components -> iOS 26.0 info symbol -> Delete

2. Force Xcode to download the "Universal" emulator by typing the following on Terminal and pressing "Enter": xcodebuild -downloadPlatform iOS -architectureVariant universal

3. Go back to Xcode, and you should now see the universal iOS 26 emulator component along with Rosetta emulators.

• Blurzschyter: Thanks @Fourth..your solution really works! I assume when I installed the 'Universal' Xcode 26.0, it will automatically installed 'Universal' simulator, but in my case, it not.
• Fourth: Glad it worked for you!
• hamid: Is it possible to download the universal simulator without deleting the Apple Silicon ?
• Fourth: You won't lose the Apple Silicon one by downloading the universal. The universal is like a bundle of both the Apple Silicon and Rosetta (x86) variations

Answer 2

I'm running into the converse, I ONLY see simulators with (Rosetta) and not any of the native arm64 simulators. I've tried the following:

1. uninstall all versions of Xcode and ComandLineTools

2. reinstall Xcode 26.0.1 and CommandLineTools for Xode 26 from the app store

3. run xcodebuild -downloadPlatform iOS -architectureVariant arm64

4. sudo rm -rf DerivedData then reluanch Xcode

5. sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

6. also tried the universal variant of iOS 26 component

I'll click on "Manage Run Destinations" and create a new simulator i.e. iPhone Air / iOS 26.0, but it won't appear in the list of runners to build on:

Run destinations

Xcode build dropdown menu

If I open the Simulator.app then launch the iPhone Air / iOS 26.0 simulator, Xcode still won't allow me to select that running simulator in the build drop down menu. (I tired quitting and restarting Xcode as well). I was seeing BOTH arm64 and Rosetta simulators, and was able to build to either in Xcode 16 prior to updating Xcode. I'm running on an M3 MacbookPro FWIW
