ios - 由于某些 Swift 版本问题，无法构建模块 XCTest？

Question

我认为这发生在最近的 XCode 更新期间。我尝试过清洁和重建，但无济于事......

Failed to build module 'XCTest' from its module interface; 
the compiler that produced it, 
'Apple Swift version 5.3 (swiftlang-1200.2.26.4 clang-1200.0.29.4)',
may have used features that aren't supported by this compiler, 
'Apple Swift version 5.3 (swiftlang-1200.0.29.2 clang-1200.0.30.1)'
