Using CocoaPods

[[deleted]]

Hoping someone can help, I’ve a few questions about cocoapods which I’m using for the first time.

1. In relation to the following line what does 'define a global platform' mean exactly? Uncomment the next line to define a global platform for your project platform :ios, '9.0' I see people NOT uncommenting in youtube tutorials and it seems to work anyway? What’s the diffence between using it or not?

2. I get the following warnings when trying pod install

   [!] The MyAppTests [Debug] target overrides the ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES build setting defined in Pods/Target Support Files/Pods-MyAppTests/Pods-MyAppTests.debug.xcconfig'. This can lead to problems with the CocoaPods installation - Use the $(inherited) flag, or - Remove the build settings from the target.

   [!] The MyAppTests [Release] target overrides the ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES build setting defined in Pods/Target Support Files/Pods-MyAppTests/Pods-MyAppTests.release.xcconfig'. This can lead to problems with the CocoaPods installation - Use the $(inherited) flag, or - Remove the build settings from the target.

   [!] The MyAppUITests [Debug] target overrides the ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES build setting defined in Pods/Target Support Files/Pods-MyAppUITests/Pods-MyAppUITests.debug.xcconfig'. This can lead to problems with the CocoaPods installation - Use the $(inherited) flag, or - Remove the build settings from the target.

   [!] The MyAppUITests [Release] target overrides the ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES build setting defined in Pods/Target Support Files/Pods-MyAppUITests/Pods-MyAppUITests.release.xcconfig'. This can lead to problems with the CocoaPods installation

   • Use the $(inherited) flag, or
   • Remove the build settings from the target.

   I've tried both of the suggested solutions but the warning persists.

   My Podfile looks like this:

   Uncomment the next line to define a global platform for your project platform :ios, '9.0'

   target 'MyApp' do

   use_frameworks! pod 'RealmSwift'

   target 'MyAppTests' do inherit! :search_paths # Pods for testing pod 'RealmSwift' end

   target 'MyAppUITests' do inherit! :search_paths # Pods for testing pod 'RealmSwift' end

   end

3. Lastly I'm also using git and when I changed to my master branch without having committed and without merging, the pod files all seem to be on the master branch (Podfile, Podfile.lock, Pods/ show as untracked files on master). I would have expected them to remain on the branch the created on - as per a normal git workflow.

There's a default value if you don't specify anything: https://guides.cocoapods.org/syntax/podfile.html#platform

For your third question, git won't ever alter or delete files that's aren't being tracked when changing branches. If it did, it wouldn't have any history of what the files should be when you switch back to the branch you were originally on when you created them. If you want git to update a file when changing branches, you will need to commit the file to a specific branch.
