If I remove all the files and just put ‘InAppWebBrowser.a’ in Plugins/iOS folder, then I get below error in Xcode build:
error: Build input file cannot be found: ‘/Users/tdpl/Documents/BuildsIphone/SooperpopTest/Libraries/Plugins/iOS/iOSInAppBrowser.mm’ (in target ‘Unity-iPhone’ from project ‘Unity-iPhone’)
