Xcode不获取pod更新。

Question

开始在Swift 3和Xcode8中开发一个过时的项目。

试图使它在Xcode 10和9下工作(分别拥有它们)。用目标平台将每个已知的位置更新为11，将快速版本更新为4/5。有许多过时的豆荚会导致构建错误，所以我用pod update和pod install更新了它们。但是，Xcode没有选择新版本，特别是SKPhotoBrowser和SwiftDate分别停留在4.1.0和4.3.0版本上，尽管pod install声明安装了6.1.0和6.0.3版本。

Podfile：

# Uncomment this line to define a global platform for your project

use_frameworks!
platform :ios, '11.0'

# Firebase pods
pod 'Firebase/Storage'
pod 'Firebase/Auth'
pod 'Firebase/Crash'
pod 'Firebase/Database'
pod 'Firebase/Messaging'
pod 'Firebase/Core'
pod 'GoogleSignIn'

#Facebook Authentication Pods
pod 'Firebase/Core'
pod 'Firebase/Auth'
pod 'FacebookCore'
pod 'FBSDKShareKit'
pod 'FBSDKLoginKit'

# Lottie Animation Framework
pod 'lottie-ios'

# Regular pods
pod 'AFNetworking'
pod 'Alamofire'
pod 'BRYXBanner'
pod 'Crashlytics'
pod 'DZNEmptyDataSet'
pod 'Fabric'
pod 'Instabug'
pod 'MBProgressHUD'
pod 'PromiseKit'
pod 'SDWebImage'
pod 'SKPhotoBrowser'
pod 'SkyFloatingLabelTextField'
pod 'Stripe' ##, :inhibit_warnings => true
pod 'SVProgressHUD'
pod 'SwiftDate'
pod 'TRVideoView'
pod 'TwicketSegmentedControl'

target 'AppName' do
end

pod install

采取的步骤：

• 所有Xcode清除- cmd + shift + k，cmd + shift + alt + k，删除已删除的数据。
• pod deintegrate && pod clean和pod install
• 闭Xcode
• 重启mac

有趣的是，似乎没有什么影响Xcode状态--无论是pod更新还是荚解体，它们总是存在于旧版本中。

如何成功地使Xcode看到新版本？

Answer 1

也许您可以尝试在podfile上显式地声明版本？类似于：

pod 'SKPhotoBrowser', '~> 6.1.0'
pod 'SwiftDate', '~> 6.0.3'

如果问题解决了，那么您可以删除显式版本。
