在使用 Swift 服務器框架 Vapor 時,因為用的是swiftPackageManager來管理依賴, xcode 打開項目后會自動拉取依賴,但是一直都拉取不成功,報如下錯誤:

在終端下使用xcodebuild -resolvePackageDependencies也不行,報同樣的錯誤:

?  hello git:(master) xcodebuild -resolvePackageDependencies
Command line invocation:
    /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -resolvePackageDependencies

Resolve Package Graph

Fetching https://github.com/vapor/vapor.git

Resolved source packages:
  hello: /Volumes/Work/vapor_project/hello

xcodebuild: error: Could not resolve package dependencies:
  An unknown error occurred. unexpected return value from ssl handshake -9806 (-1)

?  hello git:(master) 

在查了各種資料后發現給xcodebuild再加個選項就可以成功解決此問題;

xcodebuild -resolvePackageDependencies -scmProvider system
