Seeing two errors:
.../Sources/HereMaps/AnnotationState.swift:2:8 Failed to build module 'heresdk'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.5.2 (swiftlang-1300.0.47.5 clang-1300.0.29.30)', while this compiler is 'Apple Swift version 5.8 (swiftlang-5.8.0.117.11 clang-1403.0.22.8.60)'). Please select a toolchain which matches the SDK.
As well as a number of errors in the swiftinterface:
@objc @_inheritsConvenienceInitializers @IBDesignable @_Concurrency.MainActor(unsafe) open class MapView : UIKit.UIView, heresdk.MapViewBase {

Application is using MainActor features, but it does not appear as though it has set iOS 13.0 minimums.
