叮当：错误：链接器命令失败，退出代码为1（使用-v查看调用）Xcode 10，Xcode 10.1 Beta，Swift 4.2

Question

The project was working fine until I add these Cocoapods below:

platform :ios, '10.0'

target 'XXXXAPPNAME' do

use_frameworks!

pod 'KVNProgress'
pod 'OneSignal'
pod 'IQKeyboardManager'
pod 'AKMaskField'

end

The result of pod installation:

Analyzing dependencies
Downloading dependencies
Installing AKMaskField (2.0.3)
Installing IQKeyboardManager (6.0.4)
Installing KVNProgress (2.3.1)
Installing OneSignal (2.8.5)
Generating Pods project
Integrating client project

[!] Please close any current Xcode sessions and use `APPNAME.xcworkspace` for this project from now on.
Sending stats
Pod installation complete! There are 4 dependencies from the Podfile and 4 total pods installed.

and then, of course, I run the project with APPNAME.xcworkspace file

But it gives an error:

ld: warning: directory not found for option '-F/Users/MYNAME/Library/Developer/Xcode/DerivedData/APPNAME-foktozccazlvmoexywpkabjotonf/Build/Products/Debug-iphonesimulator/AKMaskField'

ld: framework not found AKMaskField

clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have googled it. I have read all questions/replies about the same topic in here StackOverflow. but I could not find a solution. I have removed derived Data also. It did not work.

Answer 1

There libraries are not updated for Swift 4.2 . This issue comes for any library that is missing the version attribute( s.swift_version = '4.2' ) in .podspec file. Also .swift-version is deprecated so that also needs to be removed for any of the pod. Now, either you can open issues so the developers can update their libraries for Swift 4.2 or you can fork and make the changes yourself and then point your repo. in pods. Last option is to use Xcode 9.4.1 until libraries are not updated.
