My git version is something older. I updated. CLI version Cocoapod is 1.3.1.
As you suggested me, I did ' pod update'.
Sub project 'Pod' has 4 directories, Frameworks,Pods,Products and Target Support Files. CorePlot directory exists under Pods. This CorePlot has src files(.m and .h) and Support Files directory.
Support Files dir has 3 files, CorePlot.xconfig, CorePlot-dummy.m and CorePlot-prefix.pch.
Still I can not find out info.plist file. Regarding Podfile, I have a Podfile which is written by myself. With latest CorePlot release, there is no problem. So I didn't use version restriction for CorePlot.
Still am I missing something?
Anyway, I wish CorePlot would have version method like AdMob.
With AdMob,
[GADRequest sdkVersion] can return AdMob SDK version string.
It is far much better method than some description in Pod projects files,I think.
