Hello Bro! Did you find the solution? I have the same problem on new Macbook M1

Dear edford! Thank you so much for the answer. But I have the same compiler Apple Swift version 5.3.2 on both laptops: Macbook Pro 2016 i5, Macbook Air 2020 M1. And the cause is not in the compile version, because my app builds with out any errors on intel's Macbook with the same compiler version, but on new M1 Macbook I get the error.

Thank you so much. I have signed im Preferences = Accounts = added my apple ID and still can not to install new simulators. Write a few days ago to Developer Program support, but nobody answered me.

There is a vendor library and today I tried to integrate version with Swift 5.3.2, but get another errors: 1) unable to load standard library for target arm-64-apple-ios9.0 2) Failed to build module ‘SciChart’ from its module interface, it may have been damaged or it may have triggered a bug in Swift compiler when it was produced. I thought to speed up my work when bought new Macbook M1, but now I can not work on it, because my apps is not build on IOS. Maybe it is possible to downgrade Xcode version, that will build my app with vendor's library Swift version 5.1.3? And for me it is still not clear why Xcode with the same version 12.4 and the same Apple Swift version 5.3.2 on Macbook Pro 2016 i5 can build my app, but on Macbook Air 2020 M1 can not do it, why? What the difference?

Vladko Krasavello! I was looking all days the decision, but nothing worked for me. Only your decision. Thank you so much)))

I have found the decision, build the app from Xcode, opened by rosetta: open Xcode through Rosetta - Right click on Xcode in applications folder - Get Info - set Open with Rosetta to true

Mr.Edford I have found the decision and it is so simple. I don't know why you did not tell me about this: open Xcode through Rosetta - Right click on Xcode in applications folder - Get Info - set Open with Rosetta to true. And thats it. No more pain! Thank you do much for your help)))

I got the new version of vendor's library with Swift compile version 5.3.2, but still can not build it, because have another types errors. And it is still so painy to use Xcode on new Mac M1 with out rosetta. Even if I want to add a new simulator, it is possible do it only with rosetta, with out it get the error: Could not download and install IOS 12.0 Simulator. Failed to download package from ADC. There are no valid accounts registered with Xcode that have the ability to access this resource. Contact Apple Developer Program Support to resolve account access issues. And I already connected my apple ID in Xcode, but still can not install a new simulator. It is very strange.
