Get error in XCode 12.4 on my new Macbook Air M1: unable to load standard library for target 'arm64-apple-ios8.0' failed to build module 'SciChart' from its module interface; the compiler that produced it, 'Apple Swift version 5.1.3 (swiftlang-1100.0.282.1 clang-1100.0.33.15)', may have used features that aren't supported by this compiler, 'Apple Swift version 5.3.2 (swiftlang-1200.0.45 clang-1200.0.32.28)' On my old Macbook Pro 2016, with intel chip I don't have any troubles. Both my Macbook have the same XCode version 12.4 and the same Swift version: Apple Swift version 5.3.2 (swiftlang-1200.0.45 clang-1200.0.32.28) Target: x86_64-apple-darwin20.3.0 What I already done: Reinstall XCode; Changed Swift Language Version; Deleted VALID_ARCHS reference according Xcode 12 Beta 2 - unable to load standard library for target 'arm64-apple-ios14.0-simulator'. And nothing works to me. Please can you help me! How to solve it?

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.

At the moment I have: Macbook Pro Max M1, iPad Pro 2022 - 1 piece. And I have a goal to connect two iPads by usb-c like monitors and have an extra left and right screen for my Macbook. Before I checked it with external HP monitor and it works. On the left side I had HP monitor connected by cable and on the right my iPad connected by bluetooth with sidecar. But I don't like this HP monitor and better would like to connect the second iPad and I need to buy it, but I'm not sure will it work or not. In apple Russian's service specialist can not tell me anything about it. Can you tell me please is it possible to connect two iPads to Macbook like external monitors by type-c cable? Or one by type-c cable and the second by bluetooth for example?
