Getting the same error.

Which Xcode are you using?

For Xcode 16 it is defined like that:

@available(macOS 10.15, iOS 13.0, watchOS 6.0, tvOS 13.0, *)
    public static func assumeIsolated<T>(_ operation: @MainActor () throws -> T, file: StaticString = #fileID, line: UInt = #line) rethrows -> T where T : Sendable

Getting the same issue on XCode 15.2 in Azure pipelines

[nalexn]

Well, I guess you need to either use a newer Xcode (15.4 might work), as there is no way to avoid assumeIsolated and support newest features

Xcode 15.4 did work

Confirming changing to 15.4 works for me.
