Why does this Xcode 11.4 environment use macOS 10.14 ? Does Travis CI host a MODIFIED Xcode for release production ?
See Apple’s release page about Xcode 11.4, which NEED at least macOS 15.2: https://developer.apple.com/documentation/xcode_release_notes/xcode_11_4_release_notes?preferredLanguage=occ
See the log from output from my build: https://travis-ci.org/github/SDWebImage/SDWebImageSwiftUI/builds/673976569
xcodebuild: error: Failed to build project SDWebImageSwiftUI with scheme SDWebImageSwiftUITests macOS.
1356 Reason: Cannot test target “SDWebImageSwiftUITests macOS” on “My Mac”: My Mac’s macOS 10.14.6 doesn’t match SDWebImageSwiftUITests macOS’s macOS 10.15 deployment target.
